Managing severe flexion deformity of the lower femur in a young child

Abstract

A severe flexion deformity of the knee that prevented a 2-year-old-child from walking caused by a 90° flexion of the lower right femur is presented. It was managed surgically by a large closed-trapezoid wedge extension-shortening osteotomy resulting in gaining the ability to walk. This case report represents a dilemma of diagnosis and management and discusses a well-planned trapezoid excision shortening osteotomy to save the neurovascular structures.
