ABSTRACT
ABSTRACT OBJECTIVE: To present our experience and preliminary results from using controlled hip dislocation to treat cam-like femoroacetabular impingement, in teenagers and young adults with sequelae of slipped capital femoral epiphysis. METHODS: This was a retrospective analysis on 15 patients who were treated in a tertiary-level hospital between 2011 and 2013. The following data were collected for analysis from these patients' files: demographic data, surgical procedure reports, joint mobility evaluations, patients' perceptions regarding clinical improvement and whether they would choose to undergo the operation again, previous hip surgery and complications. The exclusion criteria were: follow-up shorter than six months, the presence of any other hip disease, osteotomy of the proximal femur performed at the same time as the osteochondroplasty and incomplete medical files with regard to the information needed for the present study. RESULTS: Fifteen patients (17 hips) who underwent osteochondroplasty to treat femoroacetabular impingement were evaluated. Nine of them were women, the mean age was 18 years old and the minimum follow-up was two years. Two patients underwent osteochondroplasty bilaterally; eight patients were operated on the left side and five on the right side. In 14 cases, the greater trochanter was lowered (relative lengthening of the neck) in association with the osteochondroplasty. For 13 patients, their previous surgery consisted of fixation of an occurrence of slipped capital femoral epiphysis; for six patients (eight hips), flexor osteotomy was performed previously; and for one patient, hip arthroscopy was performed previously. Fourteen patients presented improvement of mobility and hip pain relief, in comparison with before the operation, and they said that they would undergo the operation again. Two complications were observed: one of loosening of the fixation of the greater trochanter and one of heterotopic ossification. CONCLUSION: The preliminary results from this study suggest that osteochondroplasty through controlled surgical hip dislocation is a good option for treating femoroacetabular impingement. Through this method, the patients reported achieving improvement of joint mobility and hip pain, with few complications.
RESUMO OBJETIVO: Relatar nossa experiência e os resultados preliminares com a luxação cirúrgica controlada do quadril no tratamento do impacto femoroacetabular (IFA) tipo CAM em adolescentes e adultos jovens com sequela de epifisiólise femoral proximal. MÉTODOS: Análise retrospectiva de 15 pacientes tratados em hospital terciário, onde foram selecionados prontuários de pacientes que fizeram o procedimento de 2011 até 2013. Os dados coletados para análise foram: dados demográficos, descrição do procedimento cirúrgico, avaliação da mobilidade articular, impressão subjetiva do paciente no que se refere à melhoria clínica e se optariam por fazer a cirurgia novamente, cirurgias anteriores no quadril e complicações. Foram excluídos pacientes com seguimento menor do que seis meses, portadores de outras doenças do quadril, submetidos a osteotomias do fêmur proximal no mesmo momento da osteocondroplastia e cujo prontuário estivesse incompleto quanto às informações necessárias para o presente estudo. RESULTADOS: Foram avaliados 15 pacientes e 17 quadris submetidos a osteocondroplastia para o tratamento do IFA, nove pacientes eram do sexo feminino, média de 18 anos e seguimento mínimo de dois anos. Quanto à lateralidade, oito pacientes foram operados do lado esquerdo e cinco do lado direito, além de dois pacientes nos quais a osteocondroplastia foi feita de forma bilateral. Em 14 casos, abaixamento do trocânter maior (alongamento relativo do colo) foi associado à osteocondroplastia. Treze pacientes tinham como cirúrgia prévia a fixação da epifisiólise, em seis (oito quadris) foi feita osteotomia flexora prévia e um fez uma artroscopia do quadril. Em 14 pacientes houve melhoria da mobilidade e da dor no quadril, quando comparada com o pré-operatório. Esses 14 pacientes relataram que fariam a cirurgia novamente. Foram observadas duas complicações, uma soltura da fixação do trocânter maior e uma ossificação heterotópica. CONCLUSÕES: Os resultados preliminares deste estudo sugerem que a osteocondroplastia pela técnica da luxação cirúrgica controlada do quadril é uma boa opção no tratamento do impacto femoroacetabular. Por esse método os pacientes relataram melhoria da mobilidade articular e dor no quadril e tiveram poucas complicações.

PURPOSE: To evaluate the clinical characteristics and the functional results of the osteochondral lesions of the talus (OLT) treated with arthroscopic osteochondroplasty. MATERIALS AND METHODS: The study was based on 25 cases (25 feet) of osteochondral lesion of talus that were treated with arthroscopic osteochondroplasty from May 1997 to June 2005 with at least 1 year follow-up. Follow-up period was average 21.8 months. The average age was 37.2 years old. Male patients were 22 while female were 3. Postoperative evaluation was performed with American Orthopedic Foot and Ankle Society (AOFAS) Functional score, patient satisfaction and complications. RESULTS: Ninety-two percent of patients had trauma history. Seventy-two percent of the lesions were located at the medial dome. As for the cartilage classification, 56% were fibrillation/fissure lesions while 44% were flap tears. Visual analogue scale (VAS) pain score improved from 6.8 points to 2.2 points, and AOFAS score improved from 71.3 points to 87.3 points. Eighty-eight percent of the patients were satisfied with the surgery and average period of returning to previous job was 6.5 weeks. CONCLUSION: We concluded that the arthroscopic osteochondroplasty is a viable surgical option for the osteochondral lesion of the talus.
