Background: Oberlin et al presented a new technique for nerve transfer that completely changed the prognosis of patients with brachial plexus injury. Currently, most of the literature addresses cases submitted to early surgical intervention, before 12 months from injury, showing consistent good results. The aim of this study was to evaluate the feasibility of the Oberlin procedure in late presentation cases (≥12 months), comparing the elbow flexion strength with patients operated earlier. Methods: We retrospectively reviewed 49 patients with partial brachial plexus injuries submitted to the Oberlin procedure. They were divided into 2 groups. Group A included 39 patients operated with <12 months of injury. The mean postoperative follow-up was 22.53 months. The interval from injury to surgery varied from 4 to 11 months (±8.45 months). Group B included 10 patients with surgery ≥12 months after injury. The mean postoperative follow-up was 32 months. The interval from injury to surgery ranged from 12 to 19 months (±15.4 months). Patients were evaluated monthly after surgery and the elbow flexion strength was measured using the British Medical Research Council scale. Results: In Group A, 24 patients presented with either good (M3) or excellent (M4) elbow flexion strength. In Group B, 9 patients presented with either good (M3) or excellent (M4) elbow flexion strength. A significant difference was not seen in the postoperative elbow flexion strength among the 2 groups. Conclusion: Biceps reinnervation with the Oberlin procedure is still feasible and should be attempted after more than 12 months of injury in partial brachial plexus injuries.
