Abstract
Purpose: Intramedullary blunt K-wire fixation was performed for pediatric forearm fractures and we report the clinical results.
Methods: From January 2014 to December 2017, we retrospectively reviewed 35 patients who underwent surgical treatment for pediatric forearm fractures under 14 years of age. The location of the fracture, pre- and postoperative angulation, and the union time were evaluated using simple radiographs. Patients were evaluated for postoperative immobilization period, postoperative range of motion of the wrist and elbow joints, and postoperative complications.
Results: The mean age of the patients was 8.1 years. The fracture site was the both in 22 cases, the radius in 8 cases, and ulna in 5 cases. The location of fracture was 10 cases in distal diaphysis, 22 cases in mid-shaft, and 3 cases in proximal diaphysis. The mean postoperative immobilization period was 5 weeks and bone union was achieved at 4 weeks. Bony union was obtained in all cases and all cases showed normal range of motion. There were no major complications such as re-fracture, pin fracture, or infection.
Conclusion: Intramedullary blunt K-wire fixation for pediatric forearm fractures may be one of the treatment methods that can be considered regardless of the location of the fracture with few complications.
