Abstract

The noninvasive expandable prosthesis is used for limb-salvage surgery following tumor resection in skeletally immature patients. The purpose of this retrospective study is to report our experience with the Repiphysis (Wright Medical Technology, Inc; Arlington, Tennessee) noninvasive expandable prosthesis for both the lower extremity and compassionate use in the upper extremity in 12 patients between 2003 and 2008. Twelve prostheses were implanted in 12 patients with an average follow-up of 38 months (range, 12-78 months). Nine patients underwent a total of 38 expansion procedures. Mean total expansion was 4.5 cm (range, 0.8-9.9 cm). No complications of lengthening occurred. Seven nononcologic complications were noted. One infection was reported in 12 patients. The mean MSTS score after rehabilitation was 24.5 (range, 13-30). The Repiphysis noninvasive prosthesis provides acceptable functional outcomes for both upper and lower extremity implantation and appears to have an advantage as compared to conventional expandable prosthetics, which require open procedures that can potentially increase the risk of infection from repeated hardware exposure.
