Patient Data
The left femoral head ossification center is small and the femoral head is laterally subluxed. The acetabulum is shallow and dysplastic.
Although the size of the femoral head ossification center, the femoral epiphysis is flattened and widened. The acetabular appearance is better, but it remains dysplastic and the hip remains laterally subluxed and uncovered.
Acetabular osteotomy has been performed and the femoral head is now in joint and well covered. There is heterotopic new bone formation laterally at the site of the osteotomy.
Case Discussion
These three x-rays taken over the course of two and a half years demonstrate features of developmental dysplasia of the hip (DDH) on the left.
