Open fractures of the tibia in children.

We treated 38 patients from 4 to 15 years old and with open growth plates for open fractures of the tibia. The average follow-up was 33 months (range, 9-122). All patients had repeated operative debridement, parenteral antibiotics, and immobilization by cast or fixation. Outcomes were analyzed with respect to age at the time of injury, grade of injury, and type of immobilization. The time to union was prolonged and averaged 21 weeks (range, 6-82). No patients younger than 11 years required bone grafting for union. The deep infection and nonunion rate was 8%, with all of these occurring in patients older than 11 years. Clinically significant leg-length discrepancy or functional limitation was encountered only in patients with an ipsilateral femur fracture or with deep infection requiring osseous debridement. Our data suggest that open tibia fractures in children older than 11 years have nonunion and infection rates that parallel those of adult patients, but that younger children have a more benign course. With aggressive wound care and adequate stabilization, few complications or sequelae should occur in open tibial shaft fractures in younger patients.
