ABSTRACT
Objective:To explore the application effect of remazolam besylate in elderly hip fracture surgery and its impact on anesthesia recovery quality and bone metabolism indicators.Methods:A total of 100 elderly patients with hip fractures admitted to Ningde Hospital from January 2021 to April 2022 were selected, all of whom underwent hip replacement surgery. According to the random number table method, they were divided into an observation group ( n=50) and a control group ( n=50). We observed the use of drugs such as remifentanil besylate combined with sufentanil for anesthesia induction and remifentanil combined with other drugs for anesthesia maintenance; The control group received anesthesia induction with drugs such as midazolam combined with sufentanil, and anesthesia maintenance with drugs such as remifentanil. Comparisons were made between the analgesic effects of anesthesia, the quality of anesthesia recovery, and the levels of hemodynamic and bone metabolism indicators at different time points between the two groups. Results:The postoperative recovery time, eye opening time, and extubation time of the observation group were shorter than those of the control group (all P<0.05); The total incidence of restlessness and coughing was lower in the control group than in the control group ( P<0.05); There was no statistically significant difference in the levels of serum osteocalcin (BGP), parathyroid hormone (PTH), and bone alkaline phosphatase (BALP) between the two groups after treatment (all P>0.05); The heart rate (HR) and mean arterial pressure (MAP) of the observation group during skin cutting (T 2) and 5 minutes after extubation (T 3) were lower than those of the control group (all P<0.05), and SpO 2 was higher than that of the control group ( P<0.05). The excellent rate of anesthesia and analgesic effect in the observation group was significantly higher than that in the control group ( P<0.05). Conclusions:Remazolam besylate has a good clinical effect in hip surgery, and the quality of anesthesia recovery is relatively high, but it has little effect on the postoperative bone metabolism indicators.
ABSTRACT
Objective:To analyze the feasibility and clinical efficacy of mirror reconstruction in total hip arthroplasty (THA) assisted by visual treatment solution (VTS) for patients with Crowe type II-III developmental dysplasia of the hip (DDH).Methods:Included in this study were 67 patients (67 hips) with unilateral Crowe type II-III DDH undergoing primary THA from June 2022 to August 2023. According to the reconstruction position of the rotation center, the patients were divided into mirror group and high group. There were 37 patients (37 hips) in the mirror group, reconstructed by referring to the rotation center of contralateral normal hip, with 8 males and 27 females, aged 40.9±16.7 years old and 30 patients (30 hips) in the high group, reconstructed by the "high hip center" strategy, with 7 males and 23 females, aged 38.3±11.1 years old. The radiographic results between the affected hip and the normal hip in 12 months postoperatively and the clinical results before and after the operation were compared.Results:All the operations for patients with Crowe type II-III DDH were completed successfully. The operation time, intraoperative blood loss and the follow-up time in the mirror group were 113.9±22.9 min, 287.8 ±181.6 ml and 12.8±1.8 months, respectively, while those in the high group were 118.0±26.2 min, 293.3±125.8 ml and 13.7±2.3 months respectively without significant difference between the two groups. In 12 months postoperatively the rotation center height, greater trochanter height and femoral offset of 37 hips in the mirror group were 16.1±3.8 mm, 17.7±5.2 mm and 34.4 ±5.1 mm, respectively, which were not significantly different from those of the normal side, while the HHS and WOMAC osteoarthritis index were significantly improved compared to those before operation from 32.3±5.3 and 76.9±5.4 points to 84.3±6.3 and 9.4±2.5 points ( t=-34.222, P<0.001; t=64.486, P<0.001). In the high group, the rotational center height, greater trochanter height and femoral offset of 30 hips were 27.9±3.7 mm, 25.4 ±7.9 mm and 35.4 ±6.2 mm, respectively, which were significantly higher than those in the normal side ( t=-15.706, P<0.001; t=-6.494, P<0.001; t=-2.555, P=0.016), and the HHS and WOMAC osteoarthritis index were significantly improved compared to those before operation from 30.9±4.8 and 78.7±5.3 points to 79.5±4.9 and 13.9±3.3 points ( t=-37.339, P<0.001; t=64.375, P<0.001). The HHS and WOMAC osteoarthritis index in the mirror group significantly improved compared with the high group in 12 months postoperatively ( t=3.404, P=0.001; t=-6.315, P<0.001). The X-ray at last follow-up showed that all prostheses were in a stable position. Conclusion:Compared with the high hip center reconstruction, satisfactory outcomes in terms of functional recovery and radiographic evaluation could be achieved in patients with Crowe type II-III DDH undergoing VTS-assisted THA of mirror reconstruction. The application of mirror reconstruction is expected to achieve the goal of restoring the anatomical structure and function of the primary hip after THA.
ABSTRACT
Objective:To investigate the effect of pelvic rotation around coronal axis on the placement angle of acetabular prosthesis after total hip arthroplasty.Methods:According to Murary's definition, the angle between the acetabular axis and the sagittal plane was defined as the acetabular abduction angle, and the angle between the acetabular axis and the coronal plane as the anterior inclination angle. A simple mathematical solid geometry model was established by using the mathematical software GeoGebra to simulate the dynamic changes of the acetabular prosthesis when it rotated around the coronal axis, and the calculation formula of the dynamic changes of the anterior inclination and abduction angle of the acetabular prosthesis was derived. MatLab software was used to generate the function graph of pelvis forward inclination and abduction angle and deduce the motion of acetabular prosthesis.Results:The dynamic changes of acetabular tilt angle and abduction angle when the pelvis rotated around the coronal axis were functionally related to the anterior-posterior tilt of the pelvis in a nonlinear pattern. When the pelvis rotates around the coronary axis, the anterior inclination angle formula is α 1=arcsin (sinβ 1×cosα×cosθ+cosβ 1×sinα); When the acetabulum axis faces downwards the abduction angle formula is θ 1=arccot (cosβ 1×cotθ-sinβ 1×tanα/sinθ); When the acetabulum axis faces upwards the abduction angle formula is θ 1=π-abs[arccot (cosβ 1×cotθ-sinβ 1×tanα/sinθ)] withα being the initial acetabular forward angle, θ being the initial acetabular abduction angle, α 1 being the forward angle of the acetabular prosthesis after pelvic rotation, θ 1 being the external expansion angle of the acetabular prosthesis after pelvic rotation and β 1 being the rotation angle of the pelvis around the coronal axis. When the pelvis is tilted backward, the anterior inclination angle of the acetabular prosthesis increases first and then decreases, and the abduction angle continues to increase. When the pelvis is tilted forward, the abduction angle decreases first and then increases, and the anterior inclination angle continues to decrease to negative. Conclusion:When the initial anterior inclination angle and abduction angle of acetabular prosthesis change, the curve of anterior inclination and abduction angle change accordingly. The larger the initial anterior inclination angle is, the faster it reaches its peak value, and the larger the peak value is, the faster the abduction angle changes. The larger the initial abduction angle is, the slower the initial anterior inclination angle and the abduction angle change.
ABSTRACT
Objective:To evaluate the relationship between preoperative serum bilirubin concentrations and postoperative delirium (POD) in the patients undergoing knee or hip replacement.Methods:Medical records from 413 patients undergoing knee or hip arthroplasty were selected from August 2020 to October 2023 at Qingdao Municipal Hospital using a nested case-control design based on the PNDABLE study cohort. The patients were divided into POD group ( n=77) and non-POD group ( n=336) according to whether POD occurred. Univariate analysis was used to analyze the influencing factors. Logistic regression was used to identify the risk factors for POD. The significance of mediation effect was tested. The receiver operating characteristic curve was drawn to evaluate the accuracy of risk factors in predicting POD. Results:There were significant differences in age, education time, ratio of diabetes history, Memorial Delirium Assessment Scale score, total bilirubin concentration, direct bilirubin concentration, indirect bilirubin concentration, Aβ 42 concentration, p-tau concentration, t-tau concentration, Aβ 42/p-tau ratio and Aβ 42/t-tau ratio between POD group and non-POD group ( P<0.05). The results of logistic regression analysis showed that preoperative serum total bilirubin, direct bilirubin and indirect bilirubin were risk factors for POD ( P<0.05). The results of mediation effects showed that the concentration of total tau protein in CSF partly mediated the relationship between high serum total bilirubin, direct bilirubin and indirect bilirubin concentrations and POD. The area under the receiver operating characteristic curve of total bilirubin, direct bilirubin and indirect bilirubin combined with CSF biomarker concentrations in predicting POD was 0.83 ( P<0.001). Conclusions:Preoperative elevated concentrations of total bilirubin, direct bilirubin and indirect bilirubin are risk factors for POD in the patients undergoing knee or hip replacement. CSF t-tau concentration has a partly mediating role in the association between serum total bilirubin, direct bilirubin and indirect bilirubin concentrations and the development of POD.

ABSTRACT
ABSTRACT BACKGROUND: The High Activity Arthroplasty Score (HAAS) is a self-administered questionnaire, developed in British English, that reliably and validly measures the levels of sports activities in patients following hip and knee arthroplasty surgery. OBJECTIVE: To cross-culturally adapt the HAAS to Brazilian Portuguese language. DESIGN AND SETTING: A cross-sectional study was conducted at a public university hospital in Brazil. METHODS: The Brazilian version of the HAAS was created through a six-step process: translation, synthesis, committee review, pretesting, back-translation, and submission to developers. The translation step was conducted by two independent bilingual translators, both native speakers of Brazilian Portuguese. The back-translation was performed by an independent translator, a native speaker of British English. To ensure the questionnaire's comprehensibility, 46 volunteers (51% men; average age 34-63) participated in the pre-testing step. RESULTS: The cross-cultural adaptation process necessitated modifications to certain terms and expressions to achieve cultural equivalence with the original HAAS. CONCLUSION: The HAAS has been translated from English into Brazilian Portuguese and culturally adapted for Brazil. The validation process for HAAS-Brazil is currently underway.

Abstract Hip arthroplasties are surgical procedures widely performed all over the world, seeking to return functionality, relieve pain, and improve the quality of life of patients affected by osteoarthritis, femoral neck fractures, osteonecrosis of the femoral head, among other etiologies. Periprosthetic joint infections are one of the most feared complications due to the high associated morbidity and mortality, with a high number of pathogens that may be associated with its etiology. The aim of the present study was to analyze aspects correlated with the occurrence of infection, diagnosis and prevention of periprosthetic joint infections in the hip associated with Staphylococcus aureus after corrective surgery for hip fractures. This is a systematic review of the literature carried out in the databases indexed in the Medical Literature Analysis and Retrieval System Online (MEDLINE) carried out in accordance with the precepts established by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. Twenty studies that addressed the diagnosis and prevention of periprosthetic joint infections after hip fractures were selected for analysis. It is observed that there is no consensus in the literature on preventive measures for the occurrence of such infectious processes. Among the risk factors for the occurrence and severity of infections by S. aureus after hip arthroplasties, obesity, longer surgical time, older age, immunosuppression, recent use of antibiotics, and multicomorbidities were mentioned. The use of biomarkers for early diagnosis, as well as screening, decolonization, and antibiotic prophylaxis processes are among the preventive procedures proposed in the literature.
Resumo As artroplastias de quadril são procedimentos cirúrgicos largamente realizados em todo o mundo buscando retorno da funcionalidade, alívio da dor e melhora da qualidade de vida dos pacientes acometidos por quadros de osteoartrite, fraturas de colo de fêmur e osteonecrose da cabeça femoral, dentre outras etiologias. As infecções articulares periprotéticas são uma das complicações mais temidas pela elevada morbimortalidade associada, com elevado número de patógenos que podem estar associados à sua etiologia. O objetivo do presente estudo foi analisar aspectos correlacionados à ocorrência da infecção, diagnóstico e prevenção de infecções articulares periprotéticas no quadril associadas a Staphylococcus aureus após cirurgia corretiva de fraturas de quadril. Trata-se de uma revisão sistemática de literatura realizada nas bases de dados indexadas na Medical Literature Analysis and Retrieval System Online (MEDLINE, na sigla em inglês) realizada de acordo com os preceitos estabelecidos pela metodologia Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA, na sigla em inglês). Foram selecionados para análise 20 estudos que abordavam o diagnóstico e prevenção de infecções articulares periprotéticas após fraturas de quadril. Observa-se que não há consenso na literatura sobre medidas preventivas para ocorrência de tais processo infecciosos. Dentre os fatores de risco para ocorrência e gravidade das infecções por S. aureus após artroplastias de quadril foram citados obesidade, maior tempo cirúrgico, maior idade, quadros de imunossupressão, uso recente de antibióticos e multicomorbidades. O uso de bio-marcadores para diagnóstico precoce, bem como processos de triagem, descolonização e antibioticoprofilaxia estão entre os procedimentos preventivos propostos na literatura.

Abstract Objective The present study aimed to compare the cure rate recovery time and Merle d'Aubigné-Postel functional (MAPF) score after single-stage surgery (C1T) or two-stage surgery (C2T) to treat prosthetic infections of the hip considering sociodemographic and clinical features of the patients. Materials and Methods The present retrospective study occurred in a single center from 2011 to 2014 with 37 studied cases including 26 treated with C1T and 11 with C2T. We compared the cure rate recovery time and MAPF score in the two groups as well as the sociodemographic and clinical features of the patients. We also considered surgical complications and the most common infectious agents. Results The C1T group had a faster functional recovery than the C2T group but there were no significant differences in the cure rate surgical complications or MAPF score. However C1T group patients were significantly younger which may have influenced the outcomes. Staphylococcus spp. was the most common infectious agent (62%). Conclusion Although C2T appears superior regarding infection cure C1T may be preferable for faster functional recovery. However it is critical to consider individual patient characteristics when choosing treatment. Further research with a larger sample size is required to confirm these results.
Resumo Objetivo Comparar a taxa de cura, o tempo de recuperação e a pontuação na escala funcional de Merle d'Aubigné-Postel (EFMA) entre a cirurgia em tempo único (C1T) e a cirurgia em dois tempos (C2T) no tratamento de infecções protéticas do quadril, considerando as características sociodemográficas e clínicas dos pacientes. Materiais e Métodos Foi realizado um estudo retrospectivo num único centro, entre 2011 e 2014, com um total de 37 casos estudados, sendo 26 tratados com C1T e 11 com C2T. Foram comparadas a taxa de cura, o tempo de recuperação e a pontuação EFMA entre os dois grupos, bem como as características sociodemográficas e clínicas dos pacientes. Foram também consideradas as complicações cirúrgicas e o agente infeccioso mais comum. Resultados O grupo C1T teve uma recuperação funcional mais rápida do que o grupo C2T, mas não houve diferenças significativas na taxa de cura, nas complicações cirúrgicas ou na pontuação EFMA. No entanto, o grupo C1T era significativamente mais jovem, o que pode ter influenciado os resultados. Staphylococcus spp. foi o agente infeccioso mais comum (62%). Conclusão Embora a C2T pareça ser superior em termos de cura de infecção, a C1T pode ser preferível para uma recuperação funcional mais rápida. No entanto, as características individuais dos pacientes devem ser consideradas na escolha do tratamento. São necessárias mais pesquisas com um tamanho de amostra maior para confirmar estes resultados.

Abstract It is not common to encounter arteriovenous malformations (AVMs) during total hip arthroplasty (THA). We report the present case to draw attention to the possibility of an AVM during the direct anterior approach (DAA) for THA, which, if not borne in mind, may lead to the myriad of complications related to excessive bleeding. An 81-year-old female presented to the emergency department with a left femoral neck fracture. She elected to undergo a THA via the DAA. Abnormal appearing blood vessels were present near the ascending circumflex branches, which provided difficulty in achieving hemostasis. Excessive blood loss was noted, and the patient received one unit of packed red blood cells during the operation. Hemoglobin and hematocrit dropped in the days following surgery, requiring several additional transfusions of blood products. When the patient complained of progressive left leg swelling on postoperative day 3, a computed tomography revealed large hematomas within the left adductors and the left iliopsoas muscle. Active extravasation was identified arising from a branch of the left profunda femoral artery, as well as an arteriovenous fistula (AVF) in this area. Bleeding was controlled by selective endovascular coil embolization. As of current knowledge, this is the first reported intraoperative discovery of congenital arteriovenous malformation (AVM) with subsequent development of postoperative arteriovenous fistula and associated symptomatic hematomas in the setting of THA using the DAA. Early recognition and intervention of vascular malformations is essential in preventing potential limb- or life-threatening surgical complication.
Resumo Não é comum encontrar malformações arteriovenosas (MAV) durante a artroplastia total do quadril (ATQ). Relatamos o presente caso para chamar a atenção para a possibilidade de uma MAV durante a abordagem anterior direta (AAD) para ATQ, que se não for considerada, pode levar a uma miríade de complicações relacionadas ao sangramento excessivo. Uma mulher de 81 anos foi apresentada ao pronto-socorro com fratura no pescoço do fêmur esquerdo. Ela optou por se submeter a uma artroplastia total do quadril (ATQ) através da AAD. Vasos sanguíneos aparentemente anormais estavam presentes perto dos ramos circunflexos ascendentes, proporcionando dificuldade em alcançar hemostasia. A perda excessiva de sangue foi notada e a paciente recebeu uma unidade de glóbulos vermelhos embalados durante a operação. Hemoglobina e hematócrito caíram nos dias seguintes à cirurgia, exigindo várias transfusões adicionais de produtos sanguíneos. Quando a paciente reclamou de inchaço progressivo na perna esquerda no terceiro dia pós-operatório, a tomografia computadorizada revelou hematomas grandes dentro dos adutores esquerdos e do músculo iliopsoas esquerdo. A extravasão ativa foi identificada a partir de um ramo da artéria femoral esquerda, bem como de uma fístula arteriovenosa (FAV) nesta área. O sangramento foi controlado por embolização seletiva da bobina endovascular. A partir do conhecimento atual, esta é a primeira descoberta intraoperatória relatada de MAC congênita com desenvolvimento subsequente de FAV pós-operatória e hematomas sintomáticos associados no cenário de ATQ utilizando a AAD. O reconhecimento precoce e a intervenção de malformações vasculares são essenciais para prevenir possíveis complicações cirúrgicas de membros ou de risco de vida.

Abstract Objective To analyze the profile and perception ofpatients on the waiting list for total hip arthroplasty (THA) about performing elective surgeries during the COVID-19 pandemic. Methods From July to November 2021, patients on the THA waiting list were interviewed during outpatient consultations. To compare the groups regarding categorical variables, the Chi-square test or Fisher's exact test was applied, and for quantitative variables the Mann-Whitney test was applied. The results were calculated using the Statistica program version 7. Results 39 patients answered the questionnaire. The mean age was 58.95 years, with 53.85% male. Approximately 60% expressed concern about contracting or transmitting COVID-19 to their family members after hospitalization for THA. 58.9% of patients felt hampered by the delay in scheduling elective surgeries during the pandemic. 23% lost or had a family member who lost their job during the pandemic, with a statistical difference for the group under 60 years old (p = 0.04). Conclusion Most patients were concerned about becoming infected and exposing family members to COVID-19 after surgery and noted damage due to suspensions and delay in scheduling elective surgeries. The economic impact of the pandemic was revealed by the rate of 23% of respondents who lost or had a family member who lost their job during the pandemic, being higher in patients under 60 years of age (p = 0.04).

Abstract Objectives Although osteonecrosis of the femoral head is a prevalent condition, its effects on gait parameters have not been thoroughly studied and are not well-established in the current literature. The primary aim of the present study is to describe gait in patients with a diagnosis of osteonecrosis. Methods This is a cross-sectional study. Nine patients diagnosed with osteonecrosis of the femoral head who were regularly followed-up at an outpatient clinic were selected for the present study and underwent gait analysis using Vicon Motion Capture Systems. Spatiotemporal data was obtained, and joint angles were calculated using an Euler angle coordinate system. Distal coordinate systems were used to calculate joint momentsand forceplatestoobtaingroundreactionforces. Results Patients with osteonecrosis presented with slower velocity (0.54 m/s ± 0.19) and smaller cadence (83.01 steps/min ± 13.23) than healthy patients. The pelvic obliquity range of motion was of 10.12° ± 3.03 and rotation was of 18.23° ± 9.17. The mean hip flexion was of 9.48° ± 3.40. Ground reaction forces showed reduced braking and propelling forces. Joint moments were reduced for flexion and adduction (0.42 Nm/kg ± 0.2 and 0.30 Nm/kg ± 0.11, respectively) but the abduction moment was increased (0.42 Nm/kg ± 0.18). Conclusions The present study showed that osteonecrosis of the femoral head presents compensatory gait mechanisms, with increased pelvic motion and decreased knee flexion to protect the hip joint. Decreased moments for hip flexion and adduction were also identified and muscle weakness for those groups may be correlated to the disease.
Resumo Objetivos Embora a osteonecrose da cabeça do fêmur seja uma lesão prevalente, seus efeitos sobre os parâmetros da marcha não foram minuciosamente estudados e não estão bem estabelecidos na literatura atual. O objetivo principal do presente estudo é descrever a marcha em pacientes com osteonecrose. Métodos Trata-se de um estudo transversal. Nove pacientes com diagnóstico de osteonecrose da cabeça do fêmur, sob acompanhamento regular em ambulatório, foram selecionados para o presente estudo e submetidos à análise da marcha com Vicon Motion Capture Systems. Os dados espaciais e temporais foram obtidos e os ângulos articulares foram calculados com o sistema de coordenadas angulares de Euler. Sistemas de coordenadas distais e plataformas de força foram utilizados para o cálculo de momentos articulares e de forças de reação ao solo, respectivamente. Resultados Os pacientes com osteonecrose apresentaram menor velocidade (0,54 m/s ± 0,19) e menor cadência (83,01 passos/minuto ± 13,23) do que pacientes saudáveis. As amplitudes de movimento de obliquidade e rotação pélvica foram de 10,12°± 3,03 e 18,23° ± 9,17, respectivamente. A média de flexão do quadril foi de 9,48° ± 3,40. O estudo das forças de reação ao solo revelou redução das forças de frenagem e propulsão. Os momentos articulares de flexão e adução caíram (0,42 Nm/kg ± 0,2 e 0,30 Nm/kg ± 0,11), mas o momento de abdução aumentou (0,42 Nm/kg ± 0,18). Conclusões O presente estudo mostrou que a osteonecrose da cabeça do fêmur é associada a mecanismos compensatórios da marcha, com aumento da movimentação pélvica e diminuição da flexão do joelho para proteção da articulação do quadril. A redução dos momentos de flexão e adução do quadril também foi identificada e a fraqueza destes grupos musculares pode estar correlacionada à doença.

Abstract Objective To evaluate the clinical and radiographic results and survival of the acetabular revision surgery of total hip arthroplasty with cemented implant without the use of reinforcement ring, associated with structural homologous bone grafting. Methods A total of 40 patients (44 hips) operated from 1995 to 2015 were retrospectively analyzed. Radiographs were evaluated according to the classification of the acetabular bone defect, graft shape, and the presence of osseointegration. Cases were considered as failures when the migration of the implant was > 5 mm in any direction, and/or the progression of radiolucency lines around the acetabular component were > 2 mm. We verified the association of radiographic findings with cases of failure using statistical tests and analyzed survival using the Kaplan-Meier curve. Results Of the 44 hips, 45.5% of the acetabular defects were Paprosky type 3A and 50% were 3B. In 65% of the hips, the graft configuration was classified as Prieto type 1 and in 31% as type 2. No radiographic evidence of osseointegration was observed in 13.6% of the cases. We observed 9 (20.5%) reconstruction failures. A correlation was observed between reconstruction failure and the absence of radiographic signs of graft osseointegration. Conclusion We observed good clinic and radiographic results, with survival of 79.54% in a mean follow-up of 9.65 years. Also, there was an association between absence of radiographic signs of osseointegration of the structural graft and failure in this series of patients with large bone defects. The failures did not correlate with the severity of the acetabular bone defect, thickness, or graft configuration.

Métodos Um total de 40 pacientes (44 quadris) operados de 1995 a 2015 foram analisados retrospectivamente. As radiografias foram avaliadas de acordo com a classificação do defeito ósseo acetabular, o formato do enxerto e à presença de osteointegração. Foram considerados casos de insucesso a migração do implante > 5 mm em qualquer direção e/ou a progressão de linhas de radioluscência em torno do componente acetabular > 2mm. Verificamos a associação dos achados radiográficos com os casos de falha utilizando testes estatísticos e analisamos a sobrevida utilizando a curva de Kaplan-Meier. Resultados Dos 44 quadris, 45,5% dos defeitos acetabulares eram Paprosky tipo 3A e 50%, 3B. Em 65% dos quadris, a configuração do enxerto foi classificada como tipo 1 de Prieto e em 31% como tipo 2. Não foi observada evidência radiográfica de osteointe-gração em 13,6% dos casos. Observamos 9 (20,5%) falhas de reconstrução. Foi observada correlação entre falha da reconstrução com a ausência de sinais radiográficos de osteointegração do enxerto. Conclusão Observamos bons resultados clínicos e radiográficos, com sobrevida de 79,54% em seguimento médio de 9,65 anos. Também houve associação entre ausência de sinais radiográficos de osteointegração do enxerto estrutural e falha nesta série de pacientes com grandes defeitos ósseos. As falhas não se correlacionaram com a severidade do defeito ósseo acetabular, espessura ou configuraçãodoenxerto.

Abstract Objective The present study aims to evaluate the effectiveness of the periarticular hip infiltration technique in the postoperative period of total hip arthroplasty. Methods This is a randomized double-blind controlled clinical trial in patients with femoral neck fractures or hip osteoarthritis submitted to a total hip arthroplasty at our institution. The periarticular infiltration technique consisted of the administration of an anesthetic (levobupivacaine) and a steroid (dexamethasone) agent in the nociceptor-rich tissues of the hip after orthopedic implants placement. The control group received an injection of 0.9% saline into the same tissues. Pain, range of motion, and use of opioid analgesic agents after 24 and 48hours of the procedure were evaluated, as well as the presence of adverse effects, time to resume walking, and total hospitalization time. Results The study evaluated 34 patients. The experimental group required fewer opioid agents between 24 and 48 hours. The reduction in pain scores was greater in the placebo group. Conclusion Periarticular anesthetic infiltration as a method of postoperative analgesia for total hip arthroplasty reduced the rates of opioid intake between 24 and 48hours. It provided no benefits regarding pain, mobility, length of stay, or complications.
Resumo Objetivo Este estudo tem como objetivo avaliar a eficácia da técnica de infiltração periarticular do quadril no pós-operatório de artroplastia total do quadril. Métodos Estudo clínico randomizado duplo-cego controlado. O estudo foi realizado nos pacientes com fratura de colo femoral ou osteoartrose de quadril, submetidos ao procedimento cirúrgico de artroplastia total do quadril em nossa instituição. A técnica de infiltração periarticular consistiu na aplicação da combinação de um anestésico (levobupivacaína) com um corticosteroide (dexametasona) nos tecidos ricos em nociceptores do quadril, após a colocação dos implantes ortopédicos. No grupo controle, foi realizada infiltração de soro fisiológico 0,9% nos mesmos tecidos. Após 24 e 48 horas do procedimento, foram avaliados os quesitos de dor, amplitude de movimentos, uso de analgésicos opióides, presença de efeitos adversos, período do início da deambulação e o tempo total de hospitalização. Resultados Trinta e quatro pacientes foram estatisticamente avaliados no estudo. Foi observada uma redução no consumo de opioides entre 24 e 48 h no grupo experimental.

Abstract Objective The present study aims to assess the reproducibility of digital planning for cementless total hip arthroplasty (THA) among surgeons with different levels of experience. In addition, it attempts to determine the degree of planning reliability based on a contralateral THA or on a spherical marker positioned at the greater trochanter for calibration. Methods Two evaluators with different experience levels (A1 and A2) performed independently the retrospective digital surgical planning of 64 cementless THAs. Next, we compared the planning with the implants used in the surgery. The reproducibility was excellent when planning and implants were identical; proper in case of a single-unit variation; and inappropriate if there was variation in two or more units. The present analysis also determined the calibration accuracy between the contralateral THA and the spherical marker at the greater trochanter level. Results The present study demonstrated greater success when the most experienced evaluator performed the planning and greater accuracy for the contralateral THA. When splitting the analysis per parameter (contralateral THA or spherical marker), there was a statistical difference only for the planning of A1 and the implants used in the surgery. This difference occurred in the excellent category, with 67.3% for contralateral THA compared with 30.6% for a spherical marker (p < 0.001), and in the inappropriate category, with 7.1% for contralateral THA compared with 30.6% for a spherical marker (p < 0.001). Conclusions Digital planning is more accurate when performed by an experienced evaluator. The contralateral prosthesis head was a better reference than a marker on the greater trochanter.
Resumo Objetivo Avaliar a reprodutibilidade do planejamento digital da artroplastia total de quadril (ATQ) sem cimento entre cirurgiões com diferentes níveis de experiência e o grau de confiabilidade no planejamento baseado na ATQ contralateral com o método de marcador esférico posicionado ao nível do trocanter maior. Método Dois avaliadores com níveis de experiência diferentes (A1 e A2) realizaram de forma independente o planejamento digital operatório retrospectivo de 64 ATQs sem cimento. O planejamento foi comparado com os implantes utilizados na cirurgia, sendo classificados como: excelentes, quando idênticos; adequados, quando houve variação de uma unidade; e inadequados, quando ocorreu variação de duas ou mais unidades. Na presente análise, também foi avaliada a acurácia do parâmetro de calibragem entre a ATQ contralateral comparada com o marcador esférico ao nível do trocanter maior. Resultados O estudo demonstrou maior êxito no planejamento quando realizado pelo avaliador mais experiente, com maior acurácia na ATQ contralateral. Ao fragmentar a análise de acordo com o parâmetro utilizado (ATQ contralateral ou marcador esférico), houve diferença estatística apenas na comparação do planejamento do avaliador A1 com os implantes utilizados na cirurgia. Esta diferença ocorreu na classificação excelente com 67,3% em ATQ contralateral como parâmetro contra 30,6% com marcador esférico (p < 0,001) e inadequado de 7,1% contra 30,6%, respectivamente (p < 0,001). Conclusões A acurácia do planejamento digital é mais precisa quando realizada por um avaliador experiente e a utilização da cabeça de prótese contralateral como referência se mostrou superior à utilização de um marcador no trocanter maior.

Abstract Objective Tranexamic acid (TXA) is an antifibrinolytic that is widely used for decreasing blood loss and blood transfusion rates in total hip arthroplasty. However, there is limited evidence of topical TXA usage in hip hemiarthroplasty for femoral neck fractures. The present study aimed to evaluate the effects of topical TXA on blood loss and on blood transfusions in femoral neck fracture patients who underwent cemented bipolar hemiarthroplasty. Methods Twenty-six patients with femoral neck fractures who were scheduled for bipolar cemented arthroplasty were randomized into two groups. The first group of 12 patients received topical TXA during their operation, whereas 14 patients in the second group received a placebo. Hematocrit was measured at 6 and 24 hours postoperatively. Blood transfusions and postoperative complications were also recorded. Results Total blood loss was not different between the TXA group and the control group (TXA group: 459.48 ± 456.32 ml, and control group: 732.98 ± 474.02 ml; p = 0.14). However, there were no patients within the TXA group who required a blood transfusion, while there were 4 patients in the control group who received allogenic blood transfusions (p = 0.044). There were no postoperative complications, such as wound complication, venous thromboembolism, or cardiovascular complications within either group. Conclusion Topical TXA could not decrease total blood loss but was able to reduce transfusion rates in patients who underwent cemented bipolar hip hemiarthroplasty in femoral neck fractures. Further studies in doses of topical TXA in a larger sample size would be beneficial. Level of Evidence II.
Resumo Objetivo O ácido tranexâmico (TXA) é um antifibrinolítico amplamente utilizado para diminuir as taxas de perda de sangue e de transfusão de sangue na artroplastia total do quadril. No entanto, há evidências limitadas de uso tópico de TXA na hemiartroplastia do quadril para fraturas no pescoço femoral. O presente estudo teve como objetivo avaliar os efeitos do TXA tópico na perda de sangue e transfusões de sangue em pacientes com fratura femoral que foram submetidos a hemiartroplastia bipolar cimentada. Métodos Vinte e seis pacientes com fraturas no pescoço femoral e programados para artroplastia cimentada bipolar foram randomizados em dois grupos. O primeiro grupo de 12 pacientes recebeu TXA tópico durante a operação; no segundo grupo, 14 pacientes receberam placebo. O hematócrito foi medido às 6 e 24 horas no pósoperatório. Também foram registradas transfusões de sangue e complicações pósoperatórias. Resultados A perda total de sangue não foi diferente entre o grupo TXA e o grupo controle (grupo TXA: 459,48 ±456,32 ml; e grupo controle: 732,98 ±474,02 ml; p = 0,14). No entanto, não houve pacientes dentro do grupo TXA que necessitaram de transfusão de sangue, enquanto 4 pacientes no grupo controle fizeram transfusões de sangue halogênicas (p = 0,044). Não houve complicações pós-operatórias, tais como complicação da ferida, tromboembolismo venoso ou complicações cardiovasculares dentro de qualquer grupo. Conclusão O TXA tópico não conseguiu diminuir a perda total de sangue, mas foi capaz de reduzir as taxas de transfusão, em pacientes submetidos a hemiartroplastia de quadril bipolar cimentada em fraturas no pescoço femoral. Outros estudos com doses de TXA tópico em um tamanho amostral maior seriam benéficos. Nível de Evidência II.

Abstract Objective The aim of the present study was to determine the influence of resident involvement on acute complication rates in revision total hip arthroplasty (THA). Methods Using the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database, 1,743 revision THAs were identified from 2008 to 2012; 949 of them involved a resident physician. Demographic information including gender and race, comorbidities including lung disease, heart disease and diabetes, operative time, length of stay, and acute postoperative complications within 30 days were analyzed. Results Resident involvement was not associated with a significant increase in the risk of acute complications. Total operative time demonstrated a statistically significant association with the involvement of a resident (161.35 minutes with resident present, 135.07 minutes without resident; p< 0.001). There was no evidence that resident involvement was associated with a longer hospital stay (5.61 days with resident present, 5.22 days without resident; p= 0.46). Conclusion Involvement of an orthopedic resident during revision THA does not appear to increase short-term postoperative complication rates, despite a significant increase in operative times.
Resumo Objetivo O objetivo do presente estudo foi determinar a influência do envolvimento dos residentes nas taxas de complicações agudas na revisão da artroplastia total do quadril (ATQ). Métodos Utilizando o banco de dados do American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP, na sigla em inglês), foram identificadas 1.743 revisões de ATQs entre 2008 e 2012; 949 delas envolveram um médico residente. Foram analisadas informações demográficas, incluindo gênero e raça, comorbidades, incluindo doenças pulmonares, doenças cardíacas e diabetes, tempo de permanência e complicações agudas pós-operatórias no prazo de 30 dias. Resultados O envolvimento dos residentes não foi associado a um aumento significativo no risco de complicações agudas. O tempo de operação total demonstrou associação estatisticamente significativa com o envolvimento de um residente (161,35 minutos com residente presente, 135,07 minutos sem residente; p< 0,001). Não houve evidência de que o envolvimento do residente tenha sido associado a um maior tempo de internação hospitalar (5,61 dias com residente presente, 5,22 dias sem residente; p= 0,46). Conclusão O envolvimento de um residente ortopédico durante a revisão da ATQ não parece aumentar as taxas de complicações pós-operatórias de curto prazo, apesar de um aumento significativo nos tempos operacionais.

Objective:To investigate the application value of auricular point pressing with beans combined with Chinese medicine for rehabilitation in older adults after total hip arthroplasty.Methods:This is a prospective case-control study. A total of 80 older adult patients with femoral neck fractures who underwent total hip arthroplasty at Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine from September 2020 to January 2022 were included in this study. These patients were randomly divided into a control group and an observation group, with 40 patients per group. The control group underwent conventional interventions, while the observation group underwent auricular point pressing with beans combined with Chinese medicine. Clinical efficacy was compared between the two groups.Results:The overall response rate in the observation group was 85.00% (34/40), which was significantly higher than 65.0% (26/40) in the control group ( χ2 = 4.27, P = 0.036). Before surgery, there were no significant differences in various indicators between the two groups (all P > 0.05). At 2 weeks after surgery, the hemoglobin level and Harris scores in the observation group were higher than those in the control group ( t = -7.11, -5.81, both P < 0.05). At 1 and 3 days and 2 weeks after surgery, the D-dimer level, prothrombin time, activated partial thrombin time, thrombin time, Visual Analogue Scale score, and Pittsburgh Sleep Quality Index (PSQI) in the observation group were significantly lower than those in the control group (all P < 0.05). At 3 days and 2 weeks after surgery, C-reactive protein, thigh and calf circumference of the affected limb in the observation group were significantly lower than those in the control group ( t = 2.34, 6.85, 4.47, 3.89, 6.63, 4.35, all P < 0.05). After surgery, the time to get off the bed and the length of hospital stay in the observation group were (3.58 ± 2.43) days and (7.14 ± 2.18) days, respectively, which were significantly shorter than (5.47 ± 2.35) days and (9.13 ± 2.14) days in the control group ( t = 3.54, 4.12, both P < 0.001). The incidence of postoperative deep vein thrombosis in the observation group was 5.00% (2/40), which was significantly lower than 10.00% (4/40) in the control group ( χ2 = 0.72, P = 0.396). Conclusion:Auricular point pressing with beans combined with Chinese medicine can promote rapid rehabilitation of older adult patients with femoral neck fractures after total hip arthroplasty.
ABSTRACT
Femoral neck fracture (FNF) in the elderly patients is currently a major health challenge worldwide, with excessive consumption of medical resources, high incidence of complications as well as suboptimal outcome and prognosis. Hip joint arthroplasty (HJA) has been the mainstream treatment for FNF in the elderly, but the conventional surgical approaches and techniques are still confronted with a series of bottlenecks such as dislocation, limp and limb length discrepancy. In recent years, direct anterior approach (DAA) for HJA (DAA-HJA) has been a major new choice in the field of joint replacement, which achieves improved clinical effectiveness of HJA in the treatment of elderly FNF, due to the fact that DAA approach involves the neuromuscular interface and accords with the idea of soft tissue retention and enhanced recovery after surgery. However, there is still a lack of unified understanding of standard technique and procedure of DAA-HJA in the treatment of elderly FNF. Therefore, relevant experts from the Hip Joint Group of Chinese Orthopedics Association of Chinese Medical Association, Youth Arthrology Group of Orthopedic Committee of PLA, Orthopedic Committee of Chongqing Medical Association, Branch of Orthopedic Surgeons of Chongqing Medical Doctor Association and Sport Medicine Committee of Chongqing Medical Association were organized to formulate the " Chinese expert consensus on the technical standard of direct anterior hip arthroplasty for elderly femoral neck fracture ( version 2023)" based on evidence-based medicine. This consensus mainly proposed 13 recommendations covering indications, surgical plans, prosthesis selections, surgical techniques and processes, and postoperative management of DAA-HJA in elderly patients with FNF, aiming to promote standardized, systematic and patient-specific diagnosis and treatment to improve the functional prognosis of the patients.
ABSTRACT
Objective:To compare the long-term clinical outcomes between cannulated screw internal fixation for stable femoral neck fractures and arthroplasty for unstable ones in the elderly patients.Methods:A retrospective study was conducted to analyze the 542 patients with femoral neck fracture who had been admitted to Department of Orthopedics and Traumatology, Beijing Jishuitan Hospital, Capital Medical University from May 2015 to April 2017. The 542 patients were divided into 2 groups based on fracture stability and treatment method. In the stable group (Garden type Ⅰ, type Ⅱ, and abduction compression type) of 121 cases who underwent cannulated screw internal fixation, there were 28 males and 93 females with a mean age of (77.6±8.1) years, and 20 cases of type Ⅰ, 101 cases of type Ⅱ, and 34 cases of abduction compression type by the Garden classification. In the unstable group (Garden type Ⅲ, type Ⅳ, and type Ⅱ with a posterior tilt angle >20°) of 421 cases who underwent arthroplasty, there were 130 males and 291 females with a mean age of (78.7 ± 6.9) years, and 14 cases of type Ⅱ, 403 cases of type Ⅲ, and 4 cases of type Ⅳ by the Garden classification. The postoperative mortality, reoperation rate, and mobility at the last follow-up were compared between the 2 groups.Results:There were no statistically significant differences in the baseline characteristics, except for serum albumin concentration and peripheral white blood cell count at admission, between the 2 groups, indicating comparability ( P>0.05). The hospital stay in the stable group [5.0 (4.0, 6.0)d] was significantly shorter than that in the unstable group [6.0 (5.0, 8.0)d], and the follow-up time for the stable group [54.4 (49.3, 58.7) months] significantly longer than that for the unstable group [52.2 (46.0, 59.3) months] ( P<0.05). A total of 158 patients (45 cases in the stable group and 113 cases in the unstable group) were lost to the last follow-up. At the last follow-up, the mortality in the stable group (18.4%, 14/76) was significantly lower than that in the unstable group (31.5%, 97/308), the reoperation rate in the former (15.8%, 12/76) significantly higher than that in the latter (3.6%, 11/308), and the capability of daily activities in the former (by the fracture mobility scoring: level 1 in 35 cases, level 2 in 13 cases, level 3 in 3 cases, level 4 in 2 cases, and level 5 in 1 case) significantly better than that in the latter (level 1 in 99 cases, level 2 in 47 cases, level 3 in 24 cases, level 4 in 22 cases, and level 5 in 5 cases) (all P<0.05). Conclusion:Compared with the arthroplasty for unstable femoral neck fractures, cannulated screw internal fixation for stable femoral neck fractures leads to a lower long-term mortality and a better capability of daily activities, but a significantly higher reoperation rate.
