Percutaneous opening wedge varus osteotomy with a multidrilling guide in Perthes' disease: a technical note on two cases.
We report a technique of percutaneous opening wedge intertrochanteric femoral osteotomy using a multidrilling guide with application of an Ilizarov external fixator in the management of Perthes' disease, and describe the early results obtained in two children. The average operative time was 96.5 min and the duration of external fixation was 51.5 days. Intraoperative blood loss was less than 20 ml. There were no significant complications. This percutaneous technique offers several advantages over currently available methods for surgical containment of Perthes' disease. These include a small incision, soft tissue preservation, sufficient stability, easy procedure, and short time in fixator.
