Abstract

Posttraumatic tibial pseudarthrosis is a relatively uncommon complication of tibia fractures in children. Although reported as a successful method of treating tibial nonunions in adults, distraction osteogenesis through a nonunion site via ring external fixation has not been described in children. The authors report three consecutive cases of distraction through an angulated, shortened, hypertrophic, posttraumatic nonunion to achieve successful union and concurrent correction of deformity. Distraction was carried out using a ring fixator with computer-guided correction. Union was achieved in each of the three patients with complete correction of deformity and length. Lengthening of 8 to 31 mm was achieved. The length of time in the external fixator ranged from 7 to 27 weeks. Pin tract infections developed in all patients; they were treated successfully using oral antibiotics. No deep infections or other significant complications developed. Each patient was followed up for at least 1 year.
