    Abstract Abstract Objective To evaluate the clinical and radiographic results as well as complications related to patients undergoing arthroscopic treatment of subspine hip impingement. Methods We retrospectively evaluated 25 patients (28 hips) who underwent arthroscopic treatment of subspine impingement between January 2012 and June 2018. The mean follow-up was 29.5 months, and the patients were evaluated clinically by using the Harris hip score modified by Byrd (MHHS), the non-arthritic hip score (NAHS), and in terms of internal rotation and hip flexion. In addition, the following items were evaluated by imaging exams: the center-edge (CE) acetabular angle, the Alpha angle, the presence of a sign of the posterior wall, the degree of arthrosis, the presence of heterotopic hip ossification, and the Hetsroni classification for subspine impingement. Results There was an average postoperative increase of 26.9 points for the MHHS, 25.4 for the NAHS (p < 0.0001), 10.5° in internal rotation (p < 0.0024), and 7.9° for hip flexion (p < 0.0001). As for the radiographic evaluation, an average reduction of 3.3° in the CE angle and of 31.6° for the Alpha angle (p < 0.0001). Eighteen cases (64.3%) were classified as grade 0 osteoarthritis of Tönnis, and 10 (35.7%) were classified as Tönnis grade 1. Two cases (7.1%) presented grade 1 ossification of Brooker. Most hips (n = 15, 53.6%) were classified as type II of Hetsroni et al. Conclusion In the present study, patients undergoing arthroscopic treatment with subspine impingement showed improvement in clinical aspects and radiographic patterns measured postoperatively, with an average follow-up of 29.5 months.

    Abstract Among the options for femoral reconstruction in total hip arthroplasty (THA) revision procedures, in cases of extensive circumferential defects, is the use of proximal femoral allografts. This technique makes it possible to correct the hip abductor mechanism and the leg length discrepancy, as well as presenting osteoconductive potential. The authors report the clinical and radiographic results from two cases of THA revision using this technique, with a minimum follow-up of 20 years.

    Abstract Stable slipped capital femoral epiphysis (SCFE) is the most common disease in the adolescent hip, with an estimated frequency of 10.8 in every 100,000 individuals. Recent studies of the biomechanics of femoroacetabular impingement indicate that small anatomical deformities of the hip arising from SCFE can potentially cause permanent acetabular chondral damage. There is no consensus about the best treatment option, especially for cases of moderate or severe chronic slippage (Southwick classification). Some authors recommend treatment with fixation in situ, in the belief that remodeling of the residual deformity of the femoral neck during growth allows proper function of the hip joint. Others recommend correction at the site of the deformity (subcapital realignment), aiming for the anatomical reduction of the epiphysis and seeking to reduce the risk of chondral degeneration. The authors of this Technical Note present an alternative to the classical techniques of subcapital realignment for the treatment of moderate and severe chronic and stable SCFE, which allows adequate access to the hip joint and anatomical reduction of the slippage, besides having the theoretical advantage of rapid rehabilitation of the patient.

    Abstract Objective: To compare clinical and imaging results and complications between patients treated for femoroacetabular impingement (FAI) who underwent either anterior open surgery or an arthroscopic approach, with a minimum follow-up of two years.
    Methods: This retrospective case-control study included patients submitted to FAI surgical treatment between November 2007 and March 2012. Patients treated with open surgery were compared with those treated with arthroscopy. Patients were clinically assessed by the modified Harris Hip Score, Non-Arthritic Hip Score, and internal hip rotation. Patients were radiographically assessed by the center-edge angle, joint space width, alpha angle, neck-head index, degree of arthrosis, and presence of heterotopic ossification of the hip.
    Results: In the study period, 56 patients (58 hips) with FAI were included; 16 underwent open surgery and 40 underwent arthroscopy. The 40 patients treated by the arthroscopic route had a mean follow-up of 29.1 months, and 75.6% presented good or excellent clinical results. The radiographic evaluation parameters progressed to normal levels. The 16 patients who underwent open surgery had a mean follow-up of 52 months, and 70.58% presented good or excellent clinical results. The radiographic evaluation parameters progressed to normal levels. Postoperative clinical and radiographic results were considered similar in both groups.
    Conclusions: Arthroscopy and open surgery treatments for FAI provided comparable clinical and radiographic results. However, a higher rate of complications was observed in the open surgery group.

    Abstract Purpose: The purpose of this study was to analyze the clinical and radiographic results of revision of loose total hip replacements, using proximal femoral allografts and a cemented implant.
    Material and methods: We retrospectively reviewed of 28 consecutive patients. Twenty patients were available for study. Each patient was scored using a modified Harris Hip Score. Radiographs were examined for endosteal and periosteal reabsorption, allograft-host union, trochanteric migration, component loosening and heterotrophic calcification.
    Results: The mean pre-operative Harris hip Score was 34 points. At the latest follow-up, the meanscore was 80 points. Nineteen cases (95%) had combined femoral defects and one patient (5%) had a segmental defect, according to the AAOS classification. Allograft resorption was seen in eight (40%) hips. There were 18 cases (90%) of allograft union, one (5%) of partial union and one (5%) of nonunion. There was one case of trochanteric migration (more than 1 cm). All femoral components were radiographically stable. The reconstruction was considered successful in 18 patients (90%).
    Conclusion: The use of proximal femoral allografts in femoral revision of loose total hip replacements has high survival and satisfactory clinical results at an average period of eight years postoperatively.

    Abstract Objetivos: O objetivo do presente trabalho é avaliar a deformidade dos ossos pélvicos e sua correlação com ângulo centro-borda acetabular (CE).
    Métodos: Foi realizado um estudo prospectivo caso-controle, entre agosto de 2014 e abril de 2015. Os critérios de inclusão foram pacientes consecutivos com idades entre 20 e 60 anos. Os critérios de exclusão foram: doença metabólica, cirurgia prévia de quadril ou coluna, radiografia evidenciando artrose de quadril ≥ Tönnis 2, displasia do desenvolvimento do quadril (DDQ) severa, sobrecobertura acetabular global, sinal do cruzamento das linhas acetabulares, deformidades decorrentes de epifisiólise ou Legg-Perthes-Calveé, e radiografia sem qualidade adequada. Foram avaliados na radiografia anteroposterior (AP) de pelve: o ângulo CE, índice acetabular (IA), sinal do cruzamento das linhas acetabulares, mensuração do eixo horizontal e vertical da hemipelve superior e inferior (H1: Linha Horizontal 1, hemipelve superior; H2: Linha Horizontal 2, hemipelve superior; V1: Linha Vertical, hemipelve superior; HR: Linha Horizontal, hemipelve inferior; VR: Linha Vertical, hemipelve inferior). As mensurações H1, H2, V1, HR e VR foram consideradas assimétricas quando, na comparação de uma hemipelve em relação ao lado contralateral, evidenciou-se uma diferença > 5 mm. Os pacientes foram separados em dois grupos: controle e grupo 1.
    Resultados: O total de pacientes avaliados no período foi de 228 (456 quadris). De acordo com os critérios estabelecidos, foram incluídos neste estudo 93 pacientes. A idade média foi de 39,9 anos (20 a 60 anos, desvio padrão [DP] = 10,5), e o ângulo CE médio do quadril direito foi de 31,5° (20° a 40°) e do esquerdo de 32,3° (20° a 40°). Um total de 38 pacientes foi incluído no grupo controle, sendo que com relação à H1, foi constatada aferição assimétrica em 4 casos (10,5%), H2 em 5 (13,1%), V1 em 7 (18,4%), HR em 5 (13,1%), e VR em 1 caso (2,63%). No grupo 1, foram incluídos 55 pacientes, sendo que com relação à H1, foi constatada aferição assimétrica em 24 casos (43,6%), H2 em 50 (90,9%), V1 em 28 (50,9%), HR em 16 (29,09%), e VR em 8 casos (14,5%). Na comparação entre o grupo controle e o grupo 1, observou-se diferença estatisticamente significativa para a assimetria das mensurações H1, H2 e V1 ( p  < 0,001).
    Conclusão: No presente trabalho, evidenciou-se correlação entre variação do ângulo CE acetabular e assimetria da hemipelve superior. Os presentes autores acreditam que o melhor entendimento das alterações morfológicas pélvicas permite uma maior facilidade no diagnóstico das deformidades articulares do quadril. ; Objective: The purpose of the present study was to evaluate the pelvic bone deformities and its correlation with the acetabular center-edge (CE) angle.
    Methods: Between August 2014 and April 2015, we prospectively evaluated patients aged between 20 and 60 years old. The exclusion criteria were: metabolic disease, previous hip or spine surgery, radiograph showing hip arthrosis ≥ Tönnis two, severe hip dysplasia, global acetabular overcoverage, acetabular crossover sign, hip deformities from slipped capital femoral epiphysis (SCFE) or Leg-Perthes-Calveé, and bad quality radiographs. At anteroposterior (AP) pelvic radiographs, we have evaluated: the CE angle, the acetabular index (IA), the acetabular crossover sign, the vertical and horizontal superior and inferior pelvic axis (H1: Horizontal line 1, superior pelvic axis; H2: Horizontal line 2, superior pelvic axis; V1: Vertical line, superior pelvic axis; HR: Horizontal line, inferior pelvic axis; VR: Vertical line, inferior pelvic axis). The superior and inferior pelvic axis were considered asymmetric when there was a difference ≥ 5 mm between both sides. Patients were divided into two groups: control and group 1.
    Results: A total of 228 patients (456 hips) were evaluated in the period. According to the established criteria, 93 patients were included. The mean age was 39.9 years old (20 to 60 years old, standard deviation [SD] = 10,5), and the mean CE angle in the right hip was 31.5° (20 o to 40°), and in the left 32.3° (20 o to 40°). The control group had 38 patients, with asymmetric H1 in 4 cases (10.5%), H2 in 5 (13.1%), V1 in 7 (18.4%), HR in 5 (13.1%) and VR in 1 (2.63%). Group 1 had 55 patients, with asymmetric H1 in 24 cases (43.6%), H2 in 50 (90.9%), V1 in 28 (50.9%), HR in 16 (29.09%) and VR in 8 (14.5%). Comparing both groups, there was statistical significance for H1, H2 and V1 asymmetry ( p  < 0.001).
    Conclusion: In the present paper, we observed the correlation between variation in the acetabular CE angle and asymmetry of the superior hemipelvis. The present authors believe that a better understanding of the pelvic morphologic alterations allows a greater facility in the diagnosis of hip articular deformities.
