RESUMO
The authors reviewed 37 children presenting with closed, unstable fractures of the proximal phalangeal head. Fractures were classified as intra-articular (n = 15), including 14 unicondylar and 1 bicondylar, or extra-articular (n = 22), including 20 subcondylar and 2 comminuted subcondylar. Eighteen patients underwent closed reduction with K-wire fixation (n = 11) or dynamic skeletal traction (n = 7). Nineteen patients underwent open reduction with K-wire fixation (n = 14) or miniscrews (n = 5). Results were considered excellent when the active range of motion (ROM) of the proximal interphalangeal joint was > or = 90 degrees (n = 26); fair, active ROM, 70 to 89 degrees (n = 6); and poor, active ROM < 70 degrees (n = 5). The intra-articular fractures were rated 9 excellent, 5 fair, and 1 poor. The extra-articular fractures were rated 17 excellent, 1 fair, and 4 poor. The 18 closed reductions, K-wire fixation (n = 11) and traction (n = 7), were rated 16 excellent and 2 fair. The 19 open reductions, K-wire fixation (n = 14) and miniscrew fixation (n = 5), were rated 10 excellent, 4 fair, and 5 poor. Closed reduction showed better results than open reduction. Dynamic skeletal traction proved to be simple and effective in treating these injuries.
