Résumé
BACKGROUND:Digital three-dimensional reconstruction technology is gradually applied to orthopedic diseases with the advantages of visualization,accuracy and non-invasiveness,but there is less evidence-based support for its use in artificial hip hemiarthroplasty for intertrochanteric fractures of the femur in the elderly. OBJECTIVE:To investigate the application value and economic effects of digital three-dimensional reconstruction techniques in artificial hip hemiarthroplasty of intertrochanteric fractures of the femur in the elderly. METHODS:One hundred and thirty elderly patients with intertrochanteric femur fractures admitted to Zunyi First People's Hospital from January 2019 to December 2022 were selected and randomly divided into a control group(n=65)and an observation group(n=65).Artificial hip hemiarthroplasty was performed in both groups.The control group adopted the film template measurement method for manual preoperative planning while the observation group adopted a digital three-dimensional reconstruction technique.Preoperative planning and intraoperative actual application of prosthesis compliance rate,fibrinogen,D-dimer,bilateral femoral eccentric distance difference,bilateral lower limb length difference,Harris hip function score,visual analog scale score,excellent and good rate of hip function,complications,and hospitalization cost were observed in both groups. RESULTS AND CONCLUSION:(1)The proportion of acetabular side and femoral side prosthesis in grade 0(fully compliant)was higher in the observation group than that in the control group(P<0.05).(2)Fibrinogen and D-dimer levels in the observation group were lower than those in the control group 3 days after surgery(P<0.05).(3)The difference in bilateral femoral eccentric distance and the difference in bilateral lower limb length in the observation group were smaller than those in the control group immediately after surgery(P<0.05).The differences in Harris and visual analog scale scores were not significantly different between the two groups preoperatively,6 and 12 months postoperatively(P>0.05).There was no significant difference in excellent and good rate of hip function between the two groups 12 months postoperatively(P>0.05).(4)There was no significant difference in the complication rate between the two groups(P>0.05).The hospitalization cost of the observation group was higher than that of the control group(P<0.05).(5)It is indicated that digital three-dimensional reconstruction technology applied in artificial hip hemiarthroplasty of intertrochanteric femoral fracture in the elderly can not only accurately determine the prosthesis type before surgery,but also accurately reconstruct the bilateral lower limbs offline,but its hospitalization cost is high.

BACKGROUND:Arthroplasty is the primary treatment for displaced femoral neck fractures in the elderly,and the choice of total hip arthroplasty versus hemiarthroplasty is currently the subject of considerable debate. OBJECTIVE:To compare the mid-and long-term survival status of total hip arthroplasty versus hemiarthroplasty under a direct anterior approach for displaced femoral neck fractures in the elderly based on the propensity score matching method. METHODS:One hundred and forty-seven elderly patients(≥65 years of age)with displaced femoral neck fractures were admitted from January 2016 to January 2021,of whom 88 had total hip arthroplasty(total hip arthroplasty group)and 59 had artificial femoral head replacement(hemiarthroplasty group).For the patients'preoperative comorbidities,the age-corrected Charlson Comorbidity Scale was used to quantify the scores and calculate patient frailty.The propensity score matching method was used to match the two groups 1:1 and to compare the operation time,bleeding,postoperative hospitalization time,hospitalization cost,nutritional index,postoperative complications,and mortality between the two groups after matching.Postoperative survival time was determined by Kaplan-Meier Survival analysis. RESULTS AND CONCLUSION:(1)After propensity score matching,a total of 42 matched pairs were successful in both groups,and the preoperative data of patients in both groups were balanced and comparable after matching(P>0.05).(2)Compared with the hemiarthroplasty group,operation time(79.71 minutes vs.59.07 minutes,P<0.001),bleeding volume(839.64 mL vs.597.83 mL,P=0.001),and hospitalization cost(56 508.15 yuan vs.41 702.85 yuan,P<0.001)were significantly higher in the total hip arthroplasty group.However,the mortality rate was lower in the total hip arthroplasty group than in the hemiarthroplasty group(36%vs.57%,HR=0.44,95%CI:0.23-0.87,P=0.018),and the mean survival time was longer in the total hip arthroplasty group than in the hemiarthroplasty group(59.4 months vs.43.7 months,P=0.024).(3)There were no statistically significant differences in postoperative hospitalization time,preoperative and postoperative nutritional indicators,and overall postoperative complication rate between the two groups(P>0.05).However,in terms of postoperative pain,the incidence of pain was significantly higher in the hemiarthroplasty group than that in the total hip arthroplasty group(24%vs.7%,P=0.035).(4)Overall,total hip arthroplasty has a better prognosis for survival,while hemiarthroplasty is more appropriate for patients with poor physical fitness.At the same time,postoperative pain may largely affect the quality and survival time of patients after hip arthroplasty.

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 Treatment modality is controversial in the unstable IT fractures. Ideal hemiarthroplasty treatment for unstable IT fractures should be comparable to that for FN fractures. Therefore, the aim of this study was to compare patients who underwent cementless hemiarthroplasty for a diagnosis of FN and unstable IT in terms of clinical outcomes, functional scores, and smartphone-based gait analysis data. Methods Case matching was applied to 50 patients with FN fracture and 133 patients with IT fracture who underwent hemiarthroplasty treatment, they were compared in terms of, preoperative and postoperative walking status, and Harris hip scores. Smartphone-based gait analysis was applied to 12 patients in the IT group and 14 patients in the FN group who could walk without support. Results There was no significant difference between patients with IT and FN fractures regarding Harris hip scores, preoperative, and postoperative walking status. In the gait analysis, gait velocity, cadence, step time, step length, and step time symmetry values were observed to be significantly better in patients in the FN group. Conclusion Cementless hemiarthroplasty operations for unstable IT fractures have similar hip scores to FN fractures. However, the walking speed and walking symmetry data were seen to be worse. This result should be considered in the selection of appropriate treatment. Level of evidence III; Retrospective study.
RESUMO Objetivo O tratamento das fraturas instáveis da IT possui modalidades de tratamento com diferentes teorias. Hemiartroplastia é o tratamento ideal para fraturas instáveis (IT), devendo ser comparável à hemiartroplastia para fraturas do colo femoral (FN). Portanto, o objetivo deste estudo foi comparar pacientes que foram submetidos a hemiartroplastia não cimentada para diagnóstico do FN e IT instável em seus resultados clínicos, considerando a escala de estado funcional e a análise dos dados de habilidade de marcha coletadas por um smartphone. Métodos A combinação de casos foi aplicada a 50 pacientes com fratura FN e 133 pacientes com fratura IT submetidos ao tratamento de hemiartroplastia, a habilidade de marcha pré e pós-operatório, incluindo suas pontuações Harris Hip, foram comparadas. A análise de marcha foi executada com smartphone em 12 pacientes do grupo IT e 14 pacientes do grupo CF, que conseguiam andar sem apoio. Resultados Não foram encontradas diferenças significativas entre os pacientes com fraturas IT e FN em relação às pontuações Harris Hip nem quanto ao estado de marcha pré e pós-operatório. Na análise da marcha, os valores de velocidade, cadência, tempo de passo, comprimento do passo e simetria do tempo de passo foram significativamente melhores nos pacientes do grupo FN. Conclusão As operações de hemiartroplastia não cimentada para fraturas instáveis de IT, têm pontuação de quadril semelhantes às fraturas FN. Entretanto, os dados de velocidade de caminhada e simetria de caminhada mostraram-se inferiores. Esses resultados devem ser considerados na escolha do tratamento adequado.Nível de evidência III; Estudo retrospectivo.
Résumé
Objective:To investigate the early clinical outcomes of a minimally invasive anterolateral approach (Orthopadische chirurgie munchen, OCM) versus a conventional (posterolateral approach, PLA) hemiarthroplasty in the treatment of senior femoral neck fractures.Methods:A retrospective analysis was performed on 90 elderly patients with femoral neck fractures who received anterolateral and posterolateral approaches for hemiarthroplasty in the Second Affiliated Hospital of Soochow University from December 2019 to June 2021 and were followed up. In the OCM group, there were 45 cases, including 18 males and 27 females, aged 83.33±5.29 years (range, 76-96 years); In the PLA group, there were 45 cases, including 13 males and 32 females, aged 81.87±5.00 years (range, 75-94 years). Postoperative, surgical indices, perioperative bleeding, and soft tissue injury were assessed; pain was assessed using the visual analogue scale (VAS), and hip function was evaluated using the Harris score and the University of California at Los Angeles (UCLA) score.Results:The incision length, postoperative hospital stay, hemoglobin reduction, and occult blood loss were lower in the OCM group than in the PLA group ( P<0.05), but there was no significant difference in intraoperative bleeding and postoperative transfusion rate ( P>0.05). Serum creatine kinase and C-reactive protein levels (232.98±83.70 IU/L and 81.67±48.85 mg/L) were lower in the OCM group than in the PLA group (296.93±124.58 IU/L and 104.79±36.75 mg/L) 1 day after surgery, and the differences were statistically significant ( t=2.86, P=0.005; t=2.54, P=0.013). Postoperative pain was significantly improved in all patients, and VAS scores were lower in the OCM group than in the PLA group at 12 h, 24 h, and 48 h postoperatively ( P<0.05). The time to get out of bed after surgery was 20.73±4.99 h in the OCM group compared with 41.69±13.58 h in the PLA group, with a statistically significant difference ( t=9.71, P<0.001). Harris scores (63.31±6.21 and 75.76±4.91) and UCLA scores (1.84±0.42 and 3.69±0.76) were higher in the OCM group on the day of discharge and at 1 month postoperatively than in the PLA group (52.69±10.01 and 71.33±3.66); (1.62±0.54 and 3.16±0.80) points, all with statistically significant differences ( P<0.05). However, the differences in Harris score and UCLA score between the two groups at 6 months postoperatively were not statistically significant ( P>0.05). There were two cases of intermuscular vein thrombosis in the OCM group, with a complication rate of 4% (2/45), and one case of dislocation in the PLA group, with a complication rate of 2% (1/45), there was no significant difference between the two groups ( P=1.000). Conclusion:The minimally invasive anterolateral approach is a more ideal procedure for elderly patients with femoral neck fractures undergoing hemiarthroplasty. It has the advantages of a short incision, small soft tissue damage, low occult blood loss, early removal from bed, a short postoperative hospital stay, an improvement in pain, and a good early recovery of hip function.

Abstract: Hallux rigidus is the degenerative pathology of the metatarsophalangeal joint of the hallux. This pathology causes pain and decreased movement. There are multiple surgical treatments for this pathology, all with their respective indications. We present the case of a 54-year-old patient diagnosed with hallux rigidus who had only the lateral aspect of the metatarsal head affected. This patient was treated with a novel surgical procedure, performing an interposition hemiarthroplasty using the hallucis brevis extender associated with a cheilectomy and exostectomy. The patient had a favorable clinical evolution with improvement evidenced by clinical scales, with resolution of the symptoms and without complications. Interposition hemiarthroplasty using the extensor hallucis brevis is a successful joint and movement preservation treatment for hallux rigidus in young patients with lateral unicompartmental involvement of the metatarsal head, in whom it is important to preserve movement.
Résumé
Background: Cementation of prosthesis achieves a good initial fix in an osteoporotic bone, however, arthroplasty using a cemented implant may be associated with increased mortality compared with an arthroplasty using an uncemented implant, as it has the risk of bone marrow and fat embolization with resulting intraoperative hypotension and increased incidence of deep vein thrombosis. This aim of the study wasto evaluate the complications, morbidity, and mortality rates associated with each of the procedures and study the radiographic changes, recovery to physical independence and advantages encountered in each of the procedures, and achieve stable fixation and early mobilization. Methods: Pre-operative and a postoperative assessment was done on patients who underwent Cemented and Uncemented for femoral neck fractures. After the procedure, the frequent follow-up was carried out. Clinical evaluation was done for limblength discrepancy, thigh pain, rotation of the limb, gait pattern, and range of movements.Results:The incidence of postoperative complications was higher in the uncemented group than in the cemented group. The cemented group showed significantly betterresults than the uncemented group regarding walking distance. There was a statistically significant difference between the two groups regarding Harris hip score.Conclusions: For elderly patients with a displaced femoral neck fracture a cemented hemiarthroplasty is favorable compared to an uncemented stem. There was no significant overall difference in mortality rate, cardiovascular and cerebrovascular complications, general complications, local complications, and reoperation rate.

Abstract Objective The aim of the present study was to compare functional results after Cemented Calcar replacement vis-a-vis Long stem Cemented hemiarthroplasty in patients aged more than 80 years with unstable intertrochanteric fractures. Methods The present prospective, randomized trial included 140 patients with AO/OTA type 31-A2, A3 intertrochanteric femur fracture, randomized into 2 treatment groups and followed-up for a minimum of 2 years. Sixty-seven patients in group A were treated with a cemented calcar replacing prosthesis, and 65 patients in group B were treated with a cemented long stem femoral stem prosthesis. The primary end points were hip functions at 2 years. The secondary end points were the complications encountered, mortality, surgical time, reoperation, blood loss, and activities of daily living. Results There were no major differences between the groups in terms of hip function, quality of life (health related), reoperation, mortality, and blood loss. However, the function in hip joint and activities of daily living deteriorated in both groups in comparison with prefracture levels. Conclusion In octogenarians with an unstable intertrochanteric fracture, cemented calcar replacing prosthesis has similar clinical results in comparison with long stem cemented hemiarthroplasty. Hemiarthroplasty with either implant is a good option in this subset of patients. Level of evidence: I

@#Introduction: Many surgical approaches have been described for hip hemiarthroplasty (HHA) treating femur neck fractures (FNFs). Direct lateral approach (DLA) is one of the most used. Today, the direct anterior approach (DAA) has become very attractive, but it seems to involve more intra-operative fractures. Our main endpoint was to demonstrate that the DAA may be a valid alternative comparing to the DLA. Materials and methods: Patients affected by FNFs and treated with HHA between the years 2016 and 2020 were studied. We divided the treatment of the fractures according to the surgical approach. The analysis was focused on perioperative complications and radiological outcomes. Results: There were a total of 166 patients. The DLA group included patients with an average age of 83.5 years and the DAA group of 83 years. We found similar surgical times (DLA 67 min vs DAA 61 min; p = 0,55), number of transfusions (DLA 3/person vs DAA 4/person; p = 0,91), perioperative complications (fractures: DLA 0 vs DAA 0 – dislocations: DLA 2,50% vs DAA 0) and functional outcomes (HHS: DLA 83 points vs DAA 87 points; p = 0,71). There were no statistical differences comparing diaphyseal filling (Canal Fill Index at the proximal third: DLA 0,79 vs DAA 0,78; p= 0,24), bone loss (Paprosky I: DLA 96,25% vs DAA 91,86%; p = 0,47) and prevalence of heterotopic ossification (Broker low degree: DLA 93,75% vs 95, 34%; p = 0,87). Conclusion: Analysing perioperative complications and studying post-operative radiographic evolution, our results suggest that the DAA is a valid alternative to the DLA in HHA treating FNFs.
Résumé
Obiective:To investigate the design, the key points of surgery and the outcome of short-term follow-up of hemi-elbow-arthroplastic bionic total humeral prosthesis by using 3D-print.Methods:The clinical data of 8 patients with humerus malignant tumor who underwent total humerus resection and a 3D-printed auxiliary hemi-elbow-arthroplastic total humeral prosthesis replacement from March 2018 to March 2020 at Peking University People's Hospital were retrospectively analyzed. The operative data, oncological outcome, complication profiles of prosthesis and functional status of all 8 patients were also analyzed. There were 3 males and 5 females with a mean age of 5-37 years. Histological diagnosis included 5 cases of osteosarcoma, 2 cases of Ewing's sarcoma and 1 case of chondrosarcoma.Results:The time for production of the prosthesis was (9.8±2.7) d, the operation time was (209±23) min and intraoperative hemorrhage was (569±173) ml. All the prostheses were implanted successfully and no patients experienced intraoperative complications. While 2 patients had postoperative complications, 1 case of temporary palsy of radial nerve and 1 case of local recurrence. LARS artificial ligament or hernia patch was used to reconstruct joint capsule and tendon-ligament attached around the elbow and shoulder joint. The flexion and extension of the elbow was (118±15)° (100-140°) and (11±9)° (0-25°), and the abduction and anteflexion of the shoulder was (28±12)° (15-50°) and (26±9)° (15-40°), respectively. The postoperative Musculoskeletal Tumor Society (MSTS)-93 scale score was (24.1±1.5) scores. The median follow-up time was 17 months (12-32 months), 7 patients had disease-free survival and 1 patient survived with tumor.Conclusions:The novel 3D-printed total humeral prosthesis with hemi-elbow-arthroplasty has a good perioperative safety, which is effective in restoring the function of elbow joint, solving the problem of stress concentration of ulnar marrow lever of total elbow joint prosthesis and lowering long-term wear rate and loosening rate of prosthesis.
Résumé
@#This is a case report of a bilateral posterior fracturedislocation of the shoulder after electrical shock and presents the first such patient treated with bilateral shoulder hemiarthroplasty. At first presentation, the upper limbs of the patient were in a position of internal rotation, and passive and active external rotations were painful. Radiographs and computed tomography of both shoulders showed bilateral posterior fracture-dislocation. Defects over 50% of the head articular surfaces led to unstable and unsuccessful initial closed and open reductions. The patient was then treated with cemented hemiarthroplasties with very good functional results two years post-operatively. This case presentation underlines the critical value of systematic clinical and radiographic evaluation of severe bilateral shoulder fracturedislocations, prior to the ultimate proper treatment with cemented humeral shoulder hemiarthroplasties, followed by appropriate rehabilitation programme, for successful patient outcomes.
Résumé
ABSTRACT Hallux rigidus produces a decrease in the dorsiflexion of the first metatarsophalangeal joint and is usually associated with the appearance of osteophytes. Hemiarthroplasty in the first proximal phalanx is a recommended surgical procedure in patients with advanced grade of hallux rigidus. Finite element analysis allows us to understand the biomechanical behavior of the foot. The objective of this work is to evaluate the biomechanical effects of an hemi implant placed in first proximal phalanx. Two models of finite elements are going to be compared, one free of pathologies and the other with a hemiarthroplasty in the first ray of the foot. We detected after inserting the prosthesis in the model that passive windlass mechanism is lost, and the lesser toes become overloaded, which leads to a loss of efficiency in gait as well as being able to cause postsurgical medical complications.

@#Introduction: Early femoral stem subsidence has been a concern as a predictor of the beginning of implant loosening, especially on cementless hip arthroplasty implants. This study aimed to determine the factors that affect femoral stem subsidence and outcome following hemiarthroplasty in the geriatric population. Materials and Methods: This is a retrospective study of 179 patients who underwent cementless bipolar hemiarthroplasty during the 2011-2019 period at an orthopaedic and traumatology hospital. Data on the patient's demography, pre-operative American Society Anaesthesiologist (ASA) score, body mass index (BMI), canal flare index (CFI), Dorr classification, and stem alignment were obtained. The primary outcomes were post-operative femoral stem subsidence, post-operative pain, and functional outcome using Harris Hip Score (HHS). Statistical analysis was conducted to identify risk factors associated with the primary outcome. Results: The mean femoral stem subsidence was 2.16 ±3.4 mm. The mean post-operative Visual Analog Score (VAS) on follow-up was 1.38 ± 1. Mean HHS on follow-up was 85.28±10.3. American Society Anaesthesiologist score 3 (p = 0.011, OR = 2.77) and varus alignment (p=0.039, OR = 6.963) were related to worse stem subsidence. Otherwise, neutral alignment (p = 0.045 and OR = 0.405) gave protection against femoral stem subsidence. The female gender (p = 0.014, OR 2.53) was associated with postoperative pain onset. Neutral alignment had significant relationship with functional outcomes (p = 0.01; OR 0.33). Conclusion: A higher ASA score and varus stem alignment were related to a higher risk of femoral stem subsidence. Meanwhile, neutral stem alignment had a protective effect on the femoral stem subsidence and outcome.

Objective:To investigate the clinical effect of long-stem hemiarthroplasty in the treatment of unstable intertrochanteric fracture in elderly patients with severe osteoporosis.Methods:A retrospective analysis was performed on 48 elderly patients with unstable intertrochanteric fractures of the femur with severe osteoporosis in Liaocheng People′s Hospital from April 2017 to April 2019.Twenty three patients received long-stem hemiarthroplasty (LHA group). Twenty five patients were treated with proximal femoral nail anti-rotation (PFNA) (PFNA group). PFNA group was used as the control group.The operative time, intraoperative blood loss, perioperative blood transfusion volume, number of intraoperative fluoroscopy, weight-bearing time after operation, the incidence of postoperative complications, hospitalization time, and Harris hip score of 1, 3, 6, 12 months after surgery, to investigate the efficacy of the application of long-stem hemiarthroplasty.Results:In LHA group, 23 patients were followed up for (18.6±3.9) (range from 12.0 to 26.0) months, and 25 patients in the PFNA group were followed up for (17.8±3.3)(range from 12.0 to 24.0) months.There was no significant difference in follow-up time between the two groups ( Z=-0.552, P=0.581). The operation time of LHA Group (60 (55, 73) h) was longer than that of PFNA Group (55 (50, 60) h). The intraoperative blood loss in LHA Group ((179.35±63.47) mL) was more than that in PFNA Group ((122.80±49.03) mL). The number of fluoroscopy in LHA Group (2 (2, 2) times)was less than that in PFNA Group (16 (14.5, 19.5) times). The time of weight bearing in LHA Group (4 (3, 5) d) was earlier than that in PFNA Group (33 (30, 36) d), and the differences were statistically significant ( Z=2.459, t=3.470, Z=6.216, Z=5.959; all P<0.05). There were no significant differences in perioperative blood transfusion, hospital stay and postoperative complications between the two groups (all P>0.05). Harris hip function score was significantly higher in LHA Group ((76.70±5.96), (82.13±6.38), (85.96±7.16), (88.78±7.67) points) and PFNA Group ((63.80±3.46), (71.56±2.55), (81.60±3.38), (88.08±4.83) points) increased gradually with the increase of follow-up time ( Fintra-group=432.557, Pintra-group<0.001), and the score reached the highest 12 months after operation.Harris hip function score of LHA group was higher than that of PFNA group( Finter-group=25.437, Pinter-group<0.001). There was interaction effect between follow-up time point and operation mode( Finteraction=53.464, Pinteraction<0.001). Conclusion:For the elderly patients with unstable intertrochanteric fracture with severe osteoporosis, the application of lengthened stem hemiarthroplasty can get out of bed early, reduce the complications of bed rest, reduce the number of intraoperative fluoroscopy, and recover the function of hip joint earlier and better with satisfactory results.
Résumé
Objective:To compare the advantages and disadvantages of hemiarthroplasty (HA) and reverse shoulder arthroplasty (RSA) in the treatment of complex proximal humeral fractures in the elderly patients.Methods:Pubmed, the Cochrane Library, EMBASE, and Chinese databases like CNKI, Wanfang Data and Weipu were searched for studies comparing HA and RSA in the treatment of complex proximal humeral fractures in the elderly (>60 years) from 2000 to 2020. After the studies were included and excluded by a set of inclusion and exclusion criteria and evaluated for their quality, their radiological and functional data were extracted and analyzed using software Stata 14.0.Results:Included in this meta-analysis were 11 studies with a total of 771 patients. RSA was superior to HA in outcomes like forward flexion ( SMD=-1.043, 95% CI: -1.551 to -0.534, P=0.000), abduction ( SMD=-0.811, 95% CI: -1.470 to -0.153, P=0.016), Constant score ( SMD=-0.699, 95% CI: -1.118 to -0.280, P=0.001), American Shoulder Elbow Surgeons’ Form (ASES) ( SMD=-0.931, 95% CI: -1.256 to -0.606, P<0.001), and Simple Shoulder Test (SST) ( SMD=-0.598, 95% CI: -1.181 to -0.016, P=0.044). HA led to a higher complication rate ( RR=2.14, 95% CI: 1.11 to 4.14, P=0.024), a higher joint stiffness rate ( RR=6.467,95% CI: 1.923 to 21.755, P=0.003) and a higher revision rate ( RR=5.796, 95% CI: 1.927 to 17.434, P=0.002). There were no statistically significant differences between RSA and HA in tuber healing rate ( RR=0.850, 95% CI: 0.669 to 1.080, P=0.182), internal rotation ( SMD=0.536, 95% CI: -0.394 to 1.466, P=0.259), external rotation ( SMD=-0.366, 95% CI: -0.916 to 0.184, P=0.192), implant infection ( RR=1.550, 95% CI: 0.330 to 7.286, P=0.579) or Disabilities of the Arm, Shoulder and Hand (DASH) score ( SMD=0.286, 95% CI: -0.278 to 0.850, P=0.032). Although there was no significant difference between RSA and HA in visual analogue scale (VAS) score ( SMD=0.440, 95% CI: -0.113 to 0.993, P=0.119), RSA scored better ( SMD=-1.101, 95% CI: -2.090 to -0.112, P=0.029). Conclusion:For elderly patients (>60 years) with complex proximal humeral fracture, RSA may be a more effective surgical intervention which can lead to better early and mid-term clinical outcomes than HA.
Résumé
Introduction: Intertrochanteric fractures occur in about 50% of all hip fracture events, with a mortality rate within 1 year after fracture reaching 15 to 20%. The most common treatment nowadays is either the bipolar hemiarthroplasty procedure or proximal femoral nail anti-rotation (PFNA), although there is still no consensus regarding which is better from the two, especially on patient mortality.Method: This study was an observational study using a retrospective cohort design. A total of 102 study subjects who met the inclusion requirements were grouped into 2 groups, one with bipolar hemiarthroplasty fixation treatment and another with PFNA fixation treatment. Mortality rate was recorded by survey 2 years after surgery.Result: Chi-square test showed that 2-year mortality rate after intertrochanteric fracture treated with bipolar hemiarthroplasty (21.4%) was significantly higher than the PFNA group (10.3%) (p=0.028). Bipolar hemiarthroplasty group also had longer length of stay (LoS) (50%) than the PFNA group (32.4%), albeit statistically insignificant (p=0.13). There was no significant difference between the 2-year mortality rate and LoS (p=0.976).Conclusion: Patients with intertrochanteric fractures who underwent bipolar hemiarthroplasty have significantly higher 2-year mortality rate than similar patients underwent fixation with PFNA, while they did not experience higher LoS than the PFNA group. Future prospective, multi-center study with larger sample size will be likely to validate similar fixation choice needed to decrease the mortality rate in intertrochanteric fractures.
Résumé
The aim of this prospective comparative study is to analyse the short term follow-up results of unstable inter-trochanteric fractures in the elderly treated with Bipolar hemi-arthroplasty and Dynamic hip screwfixation done in our institution from March2017 to October2018. Proximal femoral fractures in the elderly individuals have a tremendous impact on both the health care system and society. Upon treatment of inter-trochanteric factures with conservative management, it usually unites with a mal-union,non-union and with shortening, but the problem of non –union in trochanteric fractures has lessincidence. Because of complications associated with prolonged recumbency and its associated morbidities. Primary hemiarthroplasty in these patients provides for adequate fixation and early mobilization. It alleviates pain and improves function. It also prevents post-operative complications such as pneumonia, lung atelectasis and pressure sores. From our clinical observation we would suggest that unstable intertrochanteric fractures in elderly result most frequently from accidental fall (52.5%), being the most common described mechanism of injury

ABSTRACT Objective: An observational study was carried out to determine the rate of acute kidney injury (AKI) following surgery for hip fracture at our institution and to look for factors associated with AKI. Methods: Preoperative creatinine values were compared to post-operative results for all patients who underwent surgery for hip fracture at our institution between 1st January 2015 and 30th September 2016. AKI was defined as an increase in postoperative creatinine, greater than or equal to 1.5 times the preoperative value within 7 days. Chi-squared test and Student's t-test were used to look for factors associated with AKI. Results: Out of 500 patients, 96 developed an AKI (19.2%). Patients with chronic kidney disease (CKD) were more likely to develop AKI (30.8%) that those without it (17.2%, p = 0.018). Similarly, patients with 2 or more comorbidities were more likely to develop AKI (22.0%) than those without it (12.4%, p = 0.009). No statistically significant association was observed between type of surgery and AKI. Conclusion: A large proportion of patients following surgery for hip fracture developed AKI. Patients with CKD and the presence of 2 or more comorbidities had significantly higher rates of AKI. Level III evidence, Retrospective comparative study.
RESUMO Objetivo: Estudo observacional realizado no Altnagelvin Hospital para determinar a taxa de lesão renal aguda (LRA) após a cirurgia de fratura de quadril e procurar fatores associados à LRA. Métodos: Os valores de creatinina pré-operatória foram comparados aos resultados pós-operatórios em todos os pacientes submetidos à cirurgia de fratura de quadril entre 1º de janeiro de 2015 e 30 de setembro de 2016. A LRA foi definida como aumento da creatinina pós-operatória maior ou igual a 1,5 vezes ao valor pré-operatório dentro de 7 dias. Os testes qui-quadrado e t-Student foram usados para procurar fatores associados à LRA. Resultados: Dos 500 pacientes, 96 desenvolveram LRA (19,2%). Pacientes com doença renal crônica (DRC) foram mais propensos a desenvolver LRA (30,8%) do que os pacientes sem a doença (17,2%, p = 0,018). Da mesma forma, pacientes com duas ou mais comorbidades foram mais propensos a desenvolver LRA (22,0%) do que os pacientes sem comorbidades (12,4%, p = 0,009). Não houve associação estatisticamente significativa entre tipo de cirurgia e LRA. Conclusão: Após a cirurgia de fratura de quadril uma grande proporção de pacientes desenvolveu LRA. Pacientes com DRC e duas ou mais comorbidades tiveram taxas significativamente maiores de LRA. Nível de evidência III, Estudo comparativo retrospectivo .
Résumé
Resumen: Introducción: La artrosis glenohumeral conlleva a una pérdida funcional y a una disminución de la calidad de vida de muchos pacientes. Actualmente, no existe consenso en cuanto al uso de la hemiartroplastía o la artroplastía total como tratamiento definitivo para este padecimiento. El objetivo es mostrar los resultados del tratamiento de la artrosis glenohumeral primaria mediante hemiartroplastía en nuestro servicio. Material y métodos: Revisamos 19 hemiartroplastías (14 pacientes) realizadas entre 2004 y 2013 en pacientes con artrosis glenohumeral primaria sin alteración morfológica glenoidea. Se recabaron los datos de ocho pacientes (11 hemiartroplastías), valorándose el estado funcional, el dolor y la realización de actividades de la vida diaria mediante las escalas Constant, ASES y DASH preoperatorias, a los cinco años de seguimiento mínimo (rango 5-11 años), así como las complicaciones presentadas. Se comparó el estado preoperatorio y al final del seguimiento. Resultados: Se encontró una mejoría estadísticamente significativa (p < 0.05) en todos los parámetros analizados en el estudio. La media del dolor en la escala EVA disminuyó de 8.89 a 2.67. La escala ASES mejoró de 13.51 a 63.51 puntos de media. El Constant aumentó de 20.11 a 65.11 puntos. La puntuación media preoperatoria en la escala DASH fue de 73.68 y la postoperatoria de 28.30 puntos. La supervivencia media del implante fue de 81.82% a los siete años de seguimiento medio. Conclusión: Obtuvimos buenos resultados funcionales con la artrosis glenohumeral primaria, presentándose pocas complicaciones. La causa del fracaso fue la erosión glenoidea.
Abstract: Introduction: Glenohumeral osteoarthritis leads to a functional loss and a decrease in the quality of life of many patients that suffers it. Currently there is no agreement on the use of hemiarthroplasty or total arthroplasty as definitive treatment. The objective is to show the results of the treatment of primary glenohumeral osteoarthritis through hemiarthroplasty in our service. Material and methods: We reviewed 14 patients (19 hemiarthroplasties) performed between 2004 and 2013 in patients diagnosed with primary glenohumeral osteoarthritis without glenoid morphological anomaly. We managed to collect data from eight patients (11 hemiarthroplasties), assessing functional status, pain, and performing activities of daily living using the Constant, ASES and DASH scores preoperatively and at five years of minimum follow-up (range 5-11 years), as well as related complications. The preoperative status was compared to the end of the follow-up. Results: A significant improvement was found in all the parameters analyzed in the study (p < 0.05). The average pain in EVA score decreased from 8.89 to 2.67. The ASES improved from 13.51 to 63. 51 half point. The Constant increase of 20.11 points to 65.11 points. The mean preoperative score in the DASH score was 73.68 and 28.30 postoperatively. The average survival of the implant was 81.82% in the seven years of average follow-up. Conclusion: Shoulder hemiarthroplasty obtains good functional results in the treatment of primary glenohumeral osteoarthritis with few complications. The cause of the failure were glenoid erosion in all the cases.
