Abstract Total hip arthroplasty (THA) is a successful surgery in the treatment of hip pain, but there are potential complications, of which dislocation is one of the most common. Dislocation management is a challenging problem that requires a multimodal approach, and the use of dual mobility implants is an option. We present a patient with a history of femoral neck fracture who underwent THA with a double mobility implant. On the 18th postoperative day, after a fall to the ground, she developed prosthesis dislocation and had a complication after closed reduction, a subsequent intraprosthetic dislocation. After a radiographic diagnosis, the patient presented mechanical signs of hip flexion caused by a disassociated double mobility implant. The revision surgery was indicated, but the patient chose not to perform the necessary surgical procedure. A careful postoperative study of the radiographs revealed an eccentric femoral head and evidence of disassociated implantation in the surrounding soft tissues. Radiographs after closed reduction of intraprosthetic dislocations should be examined thoroughly.
Resumo A artroplastia total do quadril (ATQ) é uma cirurgia bem-sucedida no tratamento da dor no quadril, mas existem complicações potenciais, das quais a luxação é uma das mais comuns. O gerenciamento das luxações é um problema desafiador que requer uma abordagem multimodal, e o uso de implantes de mobilidade dupla é uma opção. Apresentamos uma paciente com história de fratura do colo do fêmur que foi submetida a ATQ com um implante de dupla mobilidade. No 18° dia pós-operatório, após queda ao solo, a paciente evoluiu com luxação da prótese e teve uma complicação após redução fechada, uma luxação intraprotética subsequente. Após um diagnóstico radiográfico, a paciente apresentou sinais mecânicos na flexão do quadril causados por um implante de mobilidade dupla desassociado. A cirurgia de revisão foi indicada, mas a paciente optou por não realizar o procedimento cirúrgico necessário. O estudo pós-operatório cuidadoso das radiografias revelou uma cabeça femoral excêntrica e evidências do implante desassociado nos tecidos moles circundantes. As radiografias após a redução fechada das luxações intraprotéticas devem ser examinadas minunciosamente.

Abstract Small osteolabral avulsions of the hip can be easily missed, and postreduction stress testing and computed tomography (CT) scans of the hip should be performed to look for these injuries. The usual modality of treatment of these unstable osteolabral avulsions is suture anchors, Herbert screws or spring plates. But when the bony avulsion is small, the use of these implants becomes a tedious job. We present a novel technique to fix small osteochondral avulsion fractures not amenable to fixation using screws or spring plates. We performed a retrospective analysis of 57 cases of patients who underwent open reduction and internal fixation for posterior fracture dislocation of the acetabulum, and we identified 6 cases of small posterior labral osteochondral fragments leading to instability. These injuries were fixed using a novel method. The mean Harris Hip Score at the final follow-up was of 92.5. Fixation of osteochondral avulsions associated with posterior hip fracture dislocation can be a difficult task if the bony fragment is small. Our technique is a simple, cost-effective and reliable way of fixing such avulsions with satisfactory outcomes.
Resumo Pequenas avulsões osteolabrais do quadril podem passar despercebidas, e testes de estresse pós-redução e tomografia computadorizada do quadril devem ser realizados para sua detecção. O tratamento dessas avulsões osteolabrais instáveis geralmente é feito com âncoras de sutura, parafusos de Herbert ou placas-molas. Em avulsões ósseas pequenas, porém, o uso desses implantes é um trabalho tedioso. Apresentamos uma nova técnica de fixação de pequenas fraturas com avulsões osteocondrais não passíveis de fixação com parafusos ou placas-molas. Realizamos uma análise retrospectiva de 57 casos de pacientes submetidos à redução aberta e fixação interna de fratura-luxação posterior do acetábulo, e identificamos 6 casos em que um pequeno fragmento osteocondral labral posterior causava instabilidade. Essas lesões foram corrigidas com um novo método. A pontuação média no Harris Hip Score no último acompanhamento foi de 92,5. A fixação de avulsões osteocondrais associadas a fratura-luxação posterior do quadril pode ser difícil se o fragmento ósseo for pequeno. Nossa técnica é uma maneira simples, econômica e confiável de corrigir tais avulsões com resultados satisfatórios.

Abstract Objective To evaluate surgeons' performance in resecting CAM-type deformities using a realistic arthroscopic surgery simulator. Methods An arthroscopic simulator was created using low-cost materials with the help of a GTMax Core A1 3D printer and the programs Invesalius and Meshmixer 2017, which were used to develop femoral head parts in ABS material, with the presence of a CAM-type deformity, to mimic a femoroacetabular impact situation. After the operations were performed by 16 surgeons, the femurs were compared to a previous model with deformity and another without, using Cloudcompare, and parameters such as the volumetric difference between the operated femurs, with and without deformity, the minimum and maximum distance between them, the percentage of the deformity resected, the estimated time for total resection of the deformity, as well as a qualitative analysis based on the images and graphs provided by the program representing the areas of the parts resected, were evaluated at the end. Results The average resection speed was 34.66 mm3/min (SD = 46 mm3/min, max = 147.33; min = −2.66). The average resection rate was 26.2% (SD = 34.7%, max = 111; min = −2). Qualitative analysis showed hyporesection of deformities and sometimes hyperresection of nondeformed areas. The simulator was highly rated by the surgeons, with a tactile sensation very similar to real surgery, according to them. Conclusion Arthroscopic simulators have proved very useful in training less experienced surgeons.
Resumo Objetivo Avaliar o desempenho de cirurgiões na ressecção de deformidades tipo CAME fazendo uso de um simulador realista de cirurgia artroscópica. Métodos Um simulador artroscópico foi criado a partir de materiais de baixo custo com auxílio de uma impressora 3D GTMax Core A1 e dos programas Invesalius e Meshmixer 2017, que foram utilizados para criar peças de cabeça de fêmur em material ABS, com a presença de uma deformidade tipo CAME, a fim de mimetizar uma situação de impacto femoroacetabular. Após as operações serem realizadas por 16 cirurgiões, os fêmures foram comparados a um modelo prévio com e outro sem deformidade pelo programa Cloudcompare, sendo avaliados ao final parâmetros como diferença volumétrica entre os fêmures operados, com e sem deformidade, distância mínima e máxima entre eles, porcentagem da deformidade ressecada, tempo estimado para ressecção total da deformidade, além de uma análise qualitativa feita com base nas imagens e gráficos fornecidos pelo programa representando as áreas das peças efetivamente ressecadas. Resultados A velocidade média de resseção foi de 34,66mm3/minuto (DP = 46 mm3/min, max = 147,33 mm3/min; min = −2,66 mm3/min). A média de ressecção obtida foi de 26,2% (DP = 34,7%, max = 111%; min = −2%). A análise qualitativa demonstrou uma hiporresecção das deformidades e, por vezes, hiperresecção de áreas não deformadas. O simulador foi muito bem avaliado pelos cirurgiões, tendo uma sensação tátil bem semelhante à cirurgia real segundo os mesmos. Conclusão Simuladores artroscópicos se mostraram muito úteis no treinamento de cirurgiões menos experientes.

Resultados: Foi identificado um total de 14.138 pacientes, com maior acometimento de pessoas do sexo masculino, com idade entre 15 e 44 anos. Como causas mais frequentes, destacaram-se os traumatismos de quadril e coxa, seguidos de traumatismos de membros superiores (ombro, antebraço, braço, punho e mão) e cabeça. Como tempo médio de permanência hospitalar, houve 4.693 diárias entre 2011 e 2021 secundárias a complicações em enfermarias e unidade de terapia intensiva, elevando cerca de 2,37% os valores repassados pelo SUS no período estudado. Em resumo, a análise da incidência de traumas nas emergências de um município do interior de Minas Gerais revela uma preocupante tendência em que homens na faixa etária de 15 a 44 anos emergem como as principais vítimas. Esse padrão pode ser influenciado por fatores como ocupação, comportamentos de risco e mobilidade. Conclusão: A compreensão dessa demografia específica é crucial para direcionar estratégias de prevenção e resposta adequadas. A implementação de medidas educativas, segurança no trânsito e promoção da saúde mental pode contribuir para mitigar os impactos dos traumas nesse grupo demográfico, melhorando sua qualidade de vida e a saúde geral da comunidade.
Objective: To determine the epidemiological profile of patients assisted by the unified health system, in a certain municipality in the interior of Minas Gerais, as well as the financial expenses and the financial transfer to trauma care centers. Material and methods: This is an ecological, descriptive study, carried out from data collection by SIH-SUS, from January 2011 to December 2021 in a municipality in the interior of Minas Gerais. Results: a total of 14,138 patients were identified, with greater involvement of male people aged between 15 and 44 years. As the most frequent causes, trauma to the hip and thigh stood out, followed by trauma to the upper limbs (shoulder, forearm, arm, wrist and hand) and head. As for the average length of hospital stay, there were 4,693 daily stays between 2011 and 2021 secondary to complications in wards and the intensive care unit. Increasing about 2.37% in the values transferred by the unified health system between the studied decade. In summary, the analysis of the incidence of trauma in emergencies in a municipality in the interior of Minas Gerais reveals a worrying trend in which men aged 15 to 44 years emerge as the main victims. This pattern can be influenced by factors such as occupation, risky behavior and mobility. Conclusion: Understanding this specific demographic is crucial to targeting appropriate prevention and response strategies. The implementation of educational measures, road safety and mental health promotion can help to mitigate the impacts of trauma in this demographic group, improving their quality of life and the general health of the community.

OBJECTIVE@#To investigate the clinical effect of total hip replacement (THA) in the treatment of traumatic arthritis secondary to acetabular fracture.@*METHODS@#From October 2019 to June 2022, 15 patients with secondary traumatic arthritis of acetabulum fracture were treated with THA. There were 8 males and 7 females, aged from 40 to 76 years old with an average of (59.20±9.46) years old. Prosthesis loosening, dislocation of hip joint, range of motion of hip joint, nerve injury and other conditions were recorded before and after surgery. Harris score, visual analogue scale (VAS) and imaging were used to evaluate hip joint function and surgical effect.@*RESULTS@#Follow-up time ranged 6 to 39 months with an average of (18.33±9.27) months. All the 15 patients successfully completed the operation, no nerve and blood vessel injury during the operation, postoperative wound healing was stageⅠ, no infection, one case of acetabular side prosthesis loosening at half a year after operation, and recovered well after revision surgery, one case of hip dislocation was cured after open reduction treatment, no adverse consequences. Harris score at the last postoperative follow-up was (88.60±4.01) points, compared with the preoperative (47.20±11.77) points, the difference was statistically significant (P<0.05), and VAS at the lateat postoperative follow-up was 1 (1) points, compared with the preoperative 8 (2) points, the difference was statistically significant (P<0.05). At the last follow-up, the pain symptoms were relieved or disappeared, and the joint function was satisfactory. The imaging data of the latest follow-up showed joint was well pseudoradiated, no abnormal ossification occurred, and the prosthesis was not loose.@*CONCLUSION@#THA is effective in the treatment of traumatic arthritis secondary to acetabular fracture and can effectively improve the quality of life of patients. Preoperative comprehensive evaluation and bone defect evaluation of patients, and intraoperative management of acetabulum, femur, internal fixation and bone defect are key factors for the success of surgery.

Femoral intertrochanteric fracture is one of the common types of fractures in the elderly. With the general improvement of medical and living standards, the number of elderly people is increasing, and the problem of osteoporosis has also become relatively prominent. Therefore, low violence can usually cause fractures in this area of the elderly, which has a significant negative impact on the quality of life of elderly patients. With the further development of medical technology and internal fixation materials, the emergence of proximal femoral nail antirotation(PFNA) has greatly improved the treatment effect of femoral intertrochanteric fractures in elderly patients. However, with the increasing number of patients treated, internal fixation failures have gradually been reported. In recent years, proximal femoral biomimetic intramedullary nail(PFBN) has been reported to have good clinical efficacy. Therefore, this article mainly elaborates on the theoretical basis, design characteristics, biomechanics, and clinical efficacy research of PFBN, providing more reference for the clinical treatment of femoral intertrochanteric fractures in elderly patients in the future.

Objective To investigate the effect of ultrasound guided block of pericapsular nerve(PENG)combined with lateral femoral cutaneous nerve(LFCN)on analgesia,stress response and postoperative cognitive function in patients undergoing hip replacement.Methods 102 patients who underwent hip Joint replacement in our hospital from September 2020 to September 2022 were selected and randomly divided into control group(51 cases)and study group(51 cases).The control group was given ultrasound guided iliac fascia space block(FICB),and the study group was given ultrasound guided PENG combined with LFCN block.The perioperative related indicators,postoperative analgesia effect,stress response indicators and postoperative cognitive function of the two groups were compared.Results There was no statistically significant difference in the comparison of surgical time between the two groups(P＞0.05).The amount of sufentanil used and the number of analgesic pump used within 48 hours after surgery in the study group were significantly lower than those in the control group(P＜0.05).The first postoperative time of getting out of bed and hospitalization in the study group were significantly shorter than those in the control group(P＜0.05).There was no statistically significant difference in VAS scores between the two groups at 6 h,12 h,24 h,and 48 h after surgery(P＞0.05).The VAS scores of the study group were significantly lower than those of the control group at 6 h,12 h,and 24 h after surgery(P＜0.05).The heart rate(HR)and Mean arterial pressure(MAP)of the control group were higher at the time of block(T1),30 min of block(T1)(T2),and the end of block(T3)than at the time of entry(T0)(P＜0.05).HR and MAP of the study group were significantly lower than those of the control group(P＜0.05).The MMSE scores of the two groups at 6 h,12 h,24 h,and 48 h after surgery were lower than those before surgery(P＜0.05),but the MMSE scores of the study group were significantly higher than those of the control group(P＜0.05).Conclusion Using ultrasound guided PENG combined with LFCN block for patients undergoing hip Joint replacement can more effectively reduce the amount of opioids and the number of use of analgesia pump,reduce postoperative pain in the exercise state,reduce stress reaction,and have less impact on cognitive function,so as to promote faster recovery of patients.

Objective To explore the feasibility of automating the measurement of abduction angle after total hip arthroplasty(THA)on postoperative radiographs by using deep learning algorithms.Methods The data were retrospectively collected.A total of 381 cases were used to develop deep learning model.Two radiologists annotated the key points on the images(lateral-superior point and medial-inferior point of acetabular cups,tear drops).The data was split into training dataset(304 cases),tuning dataset(38 cases),and test dataset(39 cases).A 2D U-net model was trained to segment the key points and the abduction angle were automatically meas-ured.After development of the model,an external validation dataset was collected(143 cases).Dice similarity coefficient(DSC)and mean absolute error(MAE)were used to evaluate the prediction efficiency of the model in the test dataset and the external validation dataset.Bland-Altman test was used to analyze the agreement between the abduction angle measured automatically by the model and the physician measurement.Results The DSC were 0.870-0.905 and 0.690-0.750 in the test dataset and the external validation dataset,and the corresponding MAE were 0.311-0.561 and 0.951-1.310.For the result of Bland-Altman analysis,only 6.52％(3/46)and 2.08％(3/144)of the abduction angle measurements in the test dataset and external validation dataset were outside the 95％limit of agreement(LoA).In the qualitative evaluation of the abduc-tion angle,the agreement of the model with the physician were 97.8％and 90.3％in the test dataset and the external validation dataset.Conclusion It is feasible to use deep learning algorithms to automatically measure the abduction angle after THA on X-ray images,achieving similar accuracy to that of physician.
