title: Surgical technique for an 'almost' percutaneous triple pelvic osteotomy for femoral head coverage in children 6-14 years of age.
abstract: A relatively simple triple pelvic osteotomy using two cosmetically small skin incisions can provide excellent coverage of the femoral head. An adductor approach and a bikini approach are used to do the osteotomy. The 'almost' percutaneous pelvic osteotomy successfully increases femoral head coverage in a concentric hip joint. The VCA angle of Lequesne and the center-edge angle of Wiberg both show significant improvement in the coverage of the femoral head. Three-dimensional computed tomography scanograms may provide a more graphic representation before and after surgery. Preoperatively, this is especially useful in evaluating posterior acetabular coverage of the femoral head. The almost percutaneous pelvic osteotomy is another possible triple pelvic osteotomy for procedures for hip dysplasia. It has a relatively low learning curve in comparison with other triple pelvic osteotomies for hip dysplasia in children aged 6-14 years. With careful patient selection, femoral head coverage can be improved with small incisions that are cosmetically acceptable.
