Abstract
Purpose
T-condylar (T-C) fractures of the distal humerus are rare in children. There is no accepted treatment for such an injury, and there is a lack of reports evaluating the outcome of T-C fractures treated by closed reduction and percutaneous fixation. The aim of this study was to evaluate the feasibility of closed reduction and percutaneous K-wire and screw (CRPKS) fixation in patients with type II and III T-C fractures according to the Toniolo-Wilkins classification modified by Canavese et al. (TWC classification).
Methods
The clinical data of 12 consecutive patients (8 males, 4 females) who were younger than 14 years of age and who had a T-C fracture that was managed by CRPKS were retrospectively evaluated. Fractures were classified according to the TWC classification. The baseline information of the patients, carrying angle (CA) and Mayo Elbow Performance Score (MEPS) were used to evaluate clinical and functional outcomes; related complications were recorded. Statistical analysis was performed.
Results
The mean age at the time of injury was 11.6 ± 1.8 years (range, 8–14). The time from injury to surgical treatment was 1.5 ± 1.0 days (range, 0–3), and the mean follow-up duration was 33.7 ± 12.3 months (range, 18–61). Surgery lasted 45.7 ± 7.6 min on average (range, 35–58). All fractures healed in 4.9 ± 1.0 weeks on average (range, 4–7). At the last follow-up visit, the CA was 12.6° ± 5.8° on the injured side and 13.8° ± 1.8° on the uninjured side (p=0.432). The MEPS was 100 (95, 100) on the injured side and 100 (100, 100) on the uninjured side (p=0.194). Three complications were recorded.
Conclusion
Good functional and radiological outcomes can be expected in pediatric patients with type II and III T-C fractures treated by CRPKS. The technique is relatively simple to perform and has a lower rate of complications.
