A 39-year-old man presented with weakness and a nonmobile mass in the buttock of 5 months' duration. Hip flexion was limited to 70 degrees. Strength was diminished for both ankle/foot plantar and dorsiflexion. Sensation was decreased on the plantar and dorsal foot. A pedunculated osseous mass measuring 6x4 cm on the posterior femoral neck was seen on plain radiographs and magnetic resonance imaging. Electromyography showed moderate sciatic neuropathy of the peroneal and tibial branches. The patient underwent excision of the tumor through a posterior approach. Due to the risk of weakening the neck, two 7.3-mm cannulated screws were passed percutaneously into the head with fluoroscopic guidance. The final pathological report indicated the tumor was an osteochondroma. At 22-month follow-up, he had full resolution of the neurologic findings. Postoperatively, the patient reported improvement in numbness and tingling in the leg but continued to have moderate buttock pain. Left hip flexion increased to 115 degrees at last follow-up.The importance of protecting the medial femoral circumflex artery during approaches to the hip is paramount. In this case, the tumor arose from the central aspect of the quadratus femoris, with the superior muscle protecting the medial femoral circumflex artery from harm. Although osteochondromas are a rare cause of mass effect, they should be considered in the differential diagnosis of sciatic nerve compression in this anatomical location.

The role of hip arthroscopy in the management of femoroacetabular impingement (FAI) has been advancing rapidly. In this case report, we describe the use of hip arthroscopy to successfully treat a femoral neck osteochondroma that caused a symptomatic labral tear in a 37 year old woman. Hip arthroscopy offers several advantages to surgical dislocation of the hip in the management of intraarticular pathology and FAI. Hip arthroscopy is minimally invasive without the significant trauma to hip musculature, is useful in treatment of labral tears generated by FAI, and can be used to resect small lesions on the femoral head.

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.

The purpose of this study is to demonstrate the assessment of intra-capsular femoral head and neck tumors, and to describe the arthroscopic surgical technique used to resect and fill the bone defects. Three cases of benign femoral head and neck lesions are presented. Two benign enchondromas and one benign osteochondroma were resected arthroscopically. Traction was used in one case. Modified Harris Hip Score improved in all three cases to scores of 95 or greater with an average improvement of 16 points with a minimum follow up of 15 months. Arthroscopic surgical resection of intra-capsular femoral hip lesions offers an effective alternative to open resection. This technique offered good outcomes in the limited cohort. We suggest that arthroscopic resection of intra-capsular femoral hip lesions be considered in relevant cases as an alternative to open resection.
