Single-Incision Triple Pelvic Osteotomy

The routine use of the triple pelvic osteotomy for the management of acetabular dysplasia in skeletally mature patients has been replaced by the Bernese periacetabular osteotomy described by Ganz. This procedure, however, is not indicated in skeletally immature patients who require acetabular reorientation because of the risk of developing a triradiate cartilage growth arrest following the necessary surgical exposure and osteotomy pattern used in the Bernese technique. The triple pelvic osteotomy, originally described by Le Coeur in 1965, has been modified several times over the past 50 years. The single anterior incision technique is a modification of the triple pelvic osteotomy that enables supraperiosteal periacetabular triradiate–preserving osteotomies performed with the patient in the supine position. This described technique is advantageous because it enables acetabular mobilization with less surgical exposure while facilitating intraoperative radiographic assessment of acetabular reorientation by performing the procedure in the supine position.
