Use of an intramedullary Kirschner wire for treatment of congenital pseudarthrosis of the tibia in children.

| Abstract |
Congenital pseudarthrosis of the tibia remains one of the most difficult, challenging conditions in pediatric orthopedics. The purpose of this study was to evaluate the long-term results of a technique consisting of excision of the pseudarthrosis, autologous bone grafting, and insertion of an intramedullary Kirschner wire into the tibia. Twenty-nine consecutive patients with congenital pseudarthrosis of the tibia were treated with this technique between 1984 and 2004, and the results were retrospectively reviewed and classified into three levels: good, fair, and poor. Complications were also noted. There were 13 patients (44.8%) who had fibular pseudarthrosis. Sixteen patients (52.2%) had primary union at the site of the tibial pseudarthrosis. Refracture occurred in 17 children (58.6%). Twenty-one children (72.4%), despite healed pseudarthrosis, still had residual valgus angulation at the ankle. Twenty-two patients (75.9%) had a residual limb-length discrepancy of greater than 3 cm. At the final follow-up, there were good results in four patients (13.8%), fair results in 12 patients (41.4%), and poor results in 13 patients (44.8%). This technique produced a relatively satisfactory long-term functional outcome, and should be considered in the management of congenital pseudarthrosis of the tibia.
