Presentation
Long history of a left-sided limp.
Patient Data
The left acetabulum has a steep contour and is shallow. Left femoral head has lost its normal rounded shape and is flattened with a short femoral neck. Plate and screws are seen following a previous left proximal femoral osteotomy.
The right femoral head is also mildly uncovered with a reduced center edge angle and a mildly shallow acetabulum consistent with acetabular dysplasia.
Case Discussion
Appearance is compatible with acetabular dysplasia (developmental dysplasia of the hip).
Typical appearances of developmental dysplasia of the hip, worse on the left. Developmental dysplasia in its more severe form is often diagnosed by screening during the first year of life. Patients with a milder form of the disease may present later as adults with vague hip symptoms, pain or limping or with secondary osteoarthritis.
