Abstract
Legg-Calvé-Perthes disease (LCPD) commonly causes sequelae in the hip joint morphology. A common variant is an oversized, nonspherical femoral head, associated with a short femoral neck and elevated greater trochanter, which leads to femoroacetabular impingement (FAI). The innovative Ganz technique for surgical hip dislocation opened up new treatment possibilities for FAI, including LCPD sequelae, without increasing the risk of avascular necrosis of the femoral head. In the ellipsoid coxa magna resulting from LCPD, joint wear is more accentuated in the central portion of the femoral head; the lateral third remains intact as it does not articulate with the acetabulum. A femoral head reduction osteotomy technique developed for such cases resects the damaged portion of the femoral head and restores its sphericity. Short-term outcomes are encouraging. The present case report presents a patient with LCPD sequelae submitted to a femoral head reduction osteotomy.
Study carried out at the Department of Orthopedics and Traumatology Centro Hospitalar Tondela-Viseu, Viseu, Portugal.
