PURPOSE: The primary objective was to compare the re-fracture incidence of both radius and ulna fracture in 2 groups treated using intramedullary Kirschner wires (K-wires) where the wires were exposed in group I and buried in group II. The secondary objective was to compare the final functional outcomes and complications incidence.
METHODS: Between March 2019 and February 2021, 60 pediatric patients with unstable radius and ulna fractures amenable to surgical intervention using intramedullary K-wires were randomized into group I (K-wires were exposed above the skin by 2 cm) or group II (K-wires were buried under the skin). In group I, K-wires were removed in the outpatient clinic, while in group II, they were removed under general anesthesia as a day-case procedure. Functional outcome per Price criteria was reported at 1-year follow-up.
RESULTS: Included patients had a mean age of 7.6 years (range: 5 to 10 y). The mean operative time was significantly higher in group II (32.33±7.51 vs. 36.77±8.70 min, P =0.03), with no difference regarding intraoperative x-ray exposure (43.12±15.52 vs. 41.6±11.96 s, P =0.67). Fracture union was achieved after a mean of 44±2.6 days in group I and 43±1.87 days in group II, with no difference between both groups ( P =0.34). One patient had re-fracture in group I and no patients in group II; however, the difference was insignificant ( P =0.12). Infection occurred in 2 patients in each group. All patients reported excellent scores per Price criteria and achieved full wrist and elbow range of motion compared with the contralateral noninjured side.
CONCLUSIONS: Exposed implants are a safe option when dealing with forearm fractures in patients younger than 11 years old, with the added advantage of fewer hospital admissions. Furthermore, it had a similar complication rate and functional outcomes compared with buried implants.
