Distal Focal Femoral Deficiency

Abstract

This report represents an interesting case of a rare distal focal femoral deficiency with a complication of hip dislocation. The deformity at the distal femur was erroneously given an initial diagnosis of proximal focal femoral deficiency, and we believe that other similar patients have been given this incorrect diagnosis. Additional reports of such patients will allow further identification of associated pathology. This study describes the features of distal focal femoral deficiency, potential orthopaedic concerns, and proposes a classification scheme for this pathology.
