Abstract:
:Congenital pseudarthrosis of the tibia presents surgeons with one of the most challenging of all orthopedic problems. The results of various forms of surgical treatment are rarely successful. This is a preliminary report on an implanted direct current bone growth stimulator (DCBGS) for treatment of congential pseudarthrosis of the tibia. The implanted stimulator achieved encouraging results in 6 patients when it was used in conjunction with cancellous bone grafting and efficient immobilization of the tibia. The leg requires long-term protection of the fracture site until skeletal maturity is complete.
