ABSTRACT
A 16-year old male patient visited the hospital complaining of inguinal pain and internal snapping of right hip joint. In physical examination, the patient was presumed to be diagnosed femoroacetabular impingement (FAI) and acetabular labral tear. In radiologic evaluation, FAI and acetabular labral tear were identified and bony tumor associated with internal snapping was found on the posteromedial portion of the femoral neck. Despite of conservative treatment, there was no symptomatic improvement. So arthroscopic labral repair, osteoplasty and resection of bony tumor were performed. The tumor was pathologically diagnosed as osteochondroma through biopsy and all symptoms improved after surgery. There was no recurrence, complication or abnormal finding during 1 year follow up. Osteochondroma located at posteromedial portion of femoral neck can be a cause of internal snapping hip and although technical demands are challenging, arthroscopic resection can be a good treatment option.

PURPOSE: This study evaluated the usefulness of ultrasonography for a diagnosis of acetabular labral tear in femoroacetabular impingement (FAI). MATERIALS AND METHODS: From March 2010 to October 2011, an ultrasonographic examination was performed in 58 patients(58 hips: 26 men and 32 women) with acetabular labral tear. The sensitivity and positive predictive value of ultrasonography were evaluated for 58 cases with acetabular labral tear confirmed by hip arthroscopy. RESULTS: The sensitivity and positive predictive value for an acetabular labral tear using ultrasonography was 89.6% and 100%, respectively. The concordance rate of an acetabular labral tear between arthroscopy and ultrasonography was 84.6%. CONCLUSION: Hip ultrasonography can make a significant contribution to a pathologic diagnosis and isa useful diagnostic tool for acetabular labral tears.
