PURPOSE: A late finding of some hips treated for @entity572 ( @entity572 ) is a growth disturbance of the lateral proximal femoral physis, which results in caput valgum and possibly @entity571 . Current treatment options include complete epiphysiodesis of the proximal femoral physis or a corrective proximal femoral osteotomy. Alternatively, a transphyseal screw through the inferomedial proximal femoral physis that preserves superolateral growth might improve this deformity. METHODS: This study evaluates the effect of such a transphyseal screw on both femoral and acetabular development in @entity1 with caput valgum following open treatment of @entity572 . These @entity1 were followed clinically and radiographically until skeletal maturity. Preoperative and postoperative radiographs were assessed, measuring the proximal femoral physeal orientation (PFPO), the head-shaft angle (HSA), Sharp's angle and the center edge angle of Wiberg (CE angle). RESULTS: Thirteen hips of 11 consecutive @entity1 were followed prospectively. The age at the time of transphyseal screw placement was between 5 and 14  years. The mean improvement of the PFPO and HSA was 14   (p  <  0.01) and 11   (p  <  0.001), respectively. The mean improvement of Sharp's angle and CE angle was 4.7   (p  <  0.01) and 5.8   (p  <  0.02), respectively. Five @entity1 underwent screw revision. CONCLUSIONS: A transphyseal screw across the proximal femoral physis improved the proximal femur and acetabular geometry.
