Object

The clinical outcomes of patients with brachial plexus injuries who underwent double fascicular transfer (DFT) using fascicles from the median and ulnar nerves to reinnervate the biceps and brachialis muscles were evaluated.

Methods

The authors conducted a retrospective chart review of 29 patients with brachial plexus injuries that were treated with DFT for restoration of elbow flexion. All patients underwent pre- and postoperative clinical evaluation using the Medical Research Council grading system.

Results

The mean patient age was 37 years (range 17–68 years), and there was a mean follow-up of 19 ± 12 months (range 8–68 months). At the most recent follow-up, all but 1 patient (97%) had regained elbow flexion. Eight patients recovered Grade M5, 15 patients recovered Grade M4, and 4 patients recovered Grade M3 elbow flexion strength. There was no evidence of functional deficit in the donor nerve distributions.

Conclusions

Study results demonstrated the reliable restoration of M4–M5 elbow flexion following double fascicular transfer in patients with brachial plexus injuries.

The authors report a case of long thoracic nerve (LTN) palsy treated with two-level motor nerve transfers of a pectoral fascicle of the middle trunk, and a branch of the thoracodorsal nerve. This procedure resulted in near-total improvement of the winged scapula deformity, and a return of excellent shoulder function. A detailed account of the postoperative physical therapy regimen is included, as this critical component of the favorable result cannot be overlooked. This case establishes the two-level motor nerve transfer as a new option for treating LTN palsy, and demonstrates that nerve transfers should be considered in the therapeutic algorithm of an idiopathic mononeuritis.
