Surgical Hip Dislocation Using the Modified Hardinge Approach for Excision of Osteocartilaginous Lesions of the Acetabulum and Femoral Neck in an Adult: A Case Report.

CASE:A 20-year-old woman presented with hip pain related to an osteocartilaginous lesion arising within the cotyloid fossa. She also had a lesion along the inferior femoral neck. Resection of both lesions was performed with surgical hip dislocation through a modified Hardinge approach. CONCLUSIONS:This unusual location for an osteocartilaginous lesion can lead to substantial pain and disability. Surgical dislocation through a modified Hardinge approach is an excellent option to concurrently resect these benign lesions of the cotyloid fossa and femoral neck without the need for trochanteric osteotomy.
