Clinical Trial Summary

This study is to evaluate the outcome of using transfixing hip k wire in Developmental dysplastic hip in patients with hypoplastic head and severe generalised ligamentous laxity.

Description:

The goal of treatment in developmental dysplasia of the hip (DDH) is to obtain and maintain a stable concentric reduction.

Surgical treatment is done by open reduction through a medial approach or anterolateral approach with pelvic osteotomy,capsulorhaphy, femoral shortening and derotational osteotomy.

Transfixing the femoral head with Kirschner wire during open reduction has long been thought to provide stability to the hip without damaging the femoral head or the acetabulum and to decrease the risk or re-dislocation.

The aim of this study is to assess the effect of transfixing the hip with Kirschner wire during the operative treatment of hip dysplasia in children after the walking age on the final radiological and clinical results and to compare the risks with the benefits of adding this step.
