Abstract

Ischiofemoral impingement (IFI) has been described in the medical literature as a cause of hip pain. IFI occurs due to an abnormal contact or reduced space between the lesser trochanter and the lateral border of the ischium and is an often unrecognised cause of pain and snapping in the hip. Association of multiple exostoses and a skeletal dysplasia characterised by an abnormal modelling of bone metaphysis and osseous deformities is highly characteristic of this disease. Consequently, multiple exostoses may narrow the ischiofemoral space and cause impingement and pain, even in the absence of malignant transformation. Surgical excision of exostosis of the lesser trochanter is a safe and effective method of treatment for patients with IFI. We present a case of left hip pain with incidental finding of hereditary multiple osteochondroma causing IFI and discuss the predisposing factors and review of literature.
