Purpose
Nonunions are a very rare complication after surgical treatment of displaced forearm fractures in children, but can occur in both the radius or ulna. The aim of this study is to evaluate predisposing factors for non-unions and to discuss treatment options.
Methods
We conducted a retrospective analysis of all patients who were treated primarily or secondary at our institution for nonunion after forearm fractures and operative treatment. Therefore, we retrospectively reviewed the medical charts and radiographs of affected patients from 1990 to 2020. We analysed demographic and fracture-related data as well as treatment options.
Results
Twenty-seven cases were identified. Median age was 12 years (7–16 years). The ulna was affected in 20 cases and the radius in 7. The most common location for ulna nonunion was the middle third of the shaft, and for the radius the mid and distal shaft. In 21 cases an open reduction was required. In 9 cases technical problems were identified. In most cases (26/27) a hypertrophic nonunion occurred. 10 of 27 (37%) nonunions healed without any surgical management after 9 (7–15) months. The median age of the conservatively managed group was 10 (6–13) years, younger than in the group with managed with reoperation [median 13 (7–16) years]. Indications for surgical intervention were increasing deformity, pain and limitation of movement.
Conclusion
Open reduction and technical problems seem to be influencing factors. A conservative approach can be adopted in asymptomatic patients, otherwise an operative management, constituting plate osteosynthesis with or without bone grafting, should be performed.
