• Patients and methods This single center retrospective study reviews the management and outcomes of 117 consecutive patients with humeral shaft fractures and associated radial nerve palsy (RNP) treated over a 20-year period (1986–2006). A total of 101 fractures were managed conservatively and 16 fractures underwent external fixation for poor bony alignment. Sixteen grade 1 and 2 open fractures underwent wound toileting alone. No patients underwent initial radial nerve exploration or opening of the fracture sites. Results All patients achieved clinical and radiological bony union at a mean of 8 weeks (range 7–12 weeks). There were no complications or pin tract infections in the operated patients. A total of 111 cases had initial spontaneous RNP recovery at a mean of 6 weeks (range 3–24 weeks) with full RNP recovery at a mean of 17 weeks (range 3–70 weeks) post-injury. Fourteen patients had no clinical/EMG signs of nerve activity at 12 weeks and 6 subsequently failed to regain any radial nerve recovery; 2 had late explorations and the lacerated nerves underwent sural nerve cable neurorraphy; and 4 patients underwent delayed tendon transposition 2–3 years after initial injury, with good/excellent functional outcomes. Conclusions Humeral fractures with associated RNP may be treated expectantly. With low rates of humeral nonunion, 95% spontaneous nerve recovery in closed fractures and 94% in grade 1 and 2 open fractures, one has the opportunity of waiting. If at 10–12 weeks there are no clinical/EMG signs of recovery, then nerve exploration/secondary reconstruction is indicated. Late tendon transfers may also give good/excellent functional results.
