Isolated osteochondroma of the femoral neck presenting as hip and leg pain. a case study

Abstract

Osteochondromas, or exostoses, are overwhelmingly found as isolated lesions although they can be present within the context of multiple hereditary exostosis. Increased exostotic load associated with multiple hereditary exostosis can lead to limb-length discrepancy, increased femoral anteversion, valgus angulation, and acetabular dysplasia. Solitary osteochondromas have been linked with bursal inflammation and pain, compression on neurovascular structures, and malignant degeneration, groin and lower extremity pain. Isolated exostosis involving the femoral neck is a rare entity which is often diagnosed late when the patient is being investigated for other problems. We present a young female with a history of hip pain for 3 years with restriction of movements around the hip joint and radicular pain which turned out to be a solitary osteochondroma of the femoral neck. Surgical excision relieved the symptoms. © MEDSPORTPRESS.
