Lesser Trochanter Osteochondroma as an Etiology for Ischiofemoral Impingement: A case report

Study design: Case Report
Abstract: Introduction: Ischiofemoral impingement (IFI) syndrome is a non-articular source of hip pain caused by compression of the quadratus femoris muscle in the space between the ischial tuberosity and the lesser trochanter of the femur. Among the rare structural causes of IFI, Osteochondroma (OC), a benign bone tumor, can present as a space-occupying lesion, reducing the ischiofemoral space and leading to soft tissue impingement. Case Report: We report a case of a 33-year-old male patient presenting with a six-month history of clicking and progressive left gluteal pain. Examination and Imaging studies revealed a narrowed ischiofemoral space associated with an OC arising from the medial aspect of the lesser trochanter. Surgical resection of the lesion led to complete resolution of the symptoms and restoration of hip function. Conclusion: This case highlights the need for a high index of suspicion for structural causes of IFI and underscores the importance of magnetic resonance imaging in the diagnosis. Early surgical intervention for OC -induced IFI can result in excellent clinical outcomes.
