RESUMO

BACKGROUND: While many authors have recommended surgery for patients with persistent symptoms of external snapping hip, it is unclear which one best relieves symptoms. Concerns with iliotibial band (ITB)-modifying techniques include altering the shape of the lateral thigh and overload of the contralateral abduction mechanism. We describe a new endoscopic technique that decreases the tension of the ITB complex by releasing the femoral insertion of the gluteus maximus tendon (GMT). DESCRIPTION OF TECHNIQUE: Via an endoscopic approach, we tenotomize the GMT near its insertion at the linea aspera through two trochanteric portals, developing a space beneath the ITB. METHODS: We reviewed eight patients (nine hips) with external snapping hip nonresponsive to nonoperative treatment treated by endoscopic GMT release. There were seven women (one bilateral) and one man, with a mean ± SD age of 35 ± 13.1 years (range, 18-55 years). Mean symptom duration was 36 ± 20.3 months (range, 16-84 months). Minimum followup was 22 months (mean, 32 ± 9.3 months; range, 22-45 months). RESULTS: Snapping and pain resolved in seven patients after the initial procedure. We performed one revision procedure with complete relief of symptoms. All eight patients returned to their previous level of activity. Average modified Harris hip score was 61 points (range, 45-70 points) preoperatively and 78 points (range, 62-93 points) at latest followup. We observed no neurovascular complications. CONCLUSIONS: Our small series suggests endoscopic release of the GMT resolves pain and snapping symptoms in most patients.

RESUMO

OBJETIVOS: O propósito deste estudo é avaliar os resultados em curto prazo do tratamento artroscópico do impacto femoroacetabular. A hipótese é a de que os resultados do tratamento artroscópico são favoráveis. MÉTODOS: Entre agosto de 2003 e agosto de 2007, 28 quadris foram submetidos ao tratamento do impacto femoroacetabular pela via artroscópica. A idade média dos pacientes foi de 34 anos, com média de seguimento de 27 meses. Quanto à melhora clínica, os pacientes foram avaliados pré e pósoperatoriamente pelo Harris Hip Score (HHS) modificado por Byrd. Os pacientes foram avaliados pré e pós-operatoriamente em relação à rotação interna do quadril acometido. Os valores obtidos nos índices acima foram analisados estatisticamente através do método de Wilcoxon para a avaliação de variáveis não paramétricas. RESULTADOS: O Harris Hip Score médio pré-operatório foi de 54,2 e o pós-operatório, de 94,8 (p < 0,001). O aumento médio do HHS foi de 37,5 pontos. Houve quatro resultados bons (15 por cento) e 24 excelentes (85 por cento). Pré-operatoriamente os pacientes apresentavam rotação interna do quadril média de 17º e pós-operatoriamente, de 36º. O aumento médio de rotação interna foi de 19º (p < 0,001). CONCLUSÃO: O tratamento artroscópico do impacto femoroacetabular tem resultados satisfatórios.


OBJECTIVE: The purpose of this study is to evaluate the short-term follow-up results of arthroscopic treatment of femoroacetabular impingement. Our hypothesis is that arthroscopic treatment results are favorable. METHODS: Between August 2003 and August 2007, 28 hips had femoroacetabular impingement treated by hip arthroscopy. The mean age was 34 years, with mean follow-up period of 27 months. Clinical results were graded with the modified Harris hip score, which was measured pre-and postoperatively. Patients had also their internal rotation analyzed. These parameters were calculated by using Wilcoxon's t test for analysis of nonparametric paired samples performed. RESULTS: The mean preoperative Harris Hip Score was 54.2, improving to 94.8 postoperatively (p<0,001). The mean increase was 37.5 points. We had 4 good results (15 percent) and 24 excellent results (85 percent). Preoperatively, the patients had a mean internal rotation of 17º, and, postoperatively, 36º. The average internal rotation increase was 19º (p<0,001). CONCLUSIONS: The arthroscopic treatment of femoroacetabular impingement presents satisfactory results.
