Purpose and background Humeral shaft fractures associated with median nerve palsy in children are not commonly seen and reported in the literature. The purpose of this retrospective study is to discuss the injury pattern, treatment options, nerve recovery, and functional outcome in these injuries. Methods We treated twelve children with median nerve palsy between 2012 and 2015. We analyzed the clinical presentations, radiological features, fracture type, displacement, treatment modality, nerve recovery pattern, time to bone union, functional outcome, 2-point discrimination (PD), range of movements, DASH score, and complications interpreted. Results The mean follow-up was 67.3 (range 59–80 months). 7/12 patients with median nerve injury recovered with hanging U slab/Shoulder immobilizer/Functional brace. Three patients who had median nerve entrapped at the fracture site required microsurgical nerve repair, and two patients required neurolysis alone. 11/12 patients (92%) had an excellent motor and sensory recovery (M5/S4) with a full range of movement. All patients achieved an excellent radiological union. The mean time to bone union was 13.5 weeks (range 11–18 weeks). The mean time for complete median nerve motor recovery in 11 patients was 25.4 weeks (range 22–26 weeks), and sensory recovery was 30.4 weeks (24–42weeks). The mean 2PD was 5.4 mm (range 5–7 mm). THE mean DASH score was 5.2 (range 2.3–18.2). One patient had M2/S3 recovery because of a treatment delay of >180 days. Conclusions We can treat acute humeral shaft fractures associated with median nerve injuries with hanging U slab/Shoulder immobilizer/Functional brace to achieve a complete nerve recovery, good radiological union, and excellent functional results. In cases of delayed humeral shaft fractures with nerve entrapment and poor nerve recovery, neuroma excision and microsurgical nerve repair give excellent results. Level of evidence IV. |
