Object In C7–T1 brachial plexus palsies, finger extension and flexion are absent. At the authors' institution, finger flexion has been successfully reconstructed by transferring the brachialis motor branch to the anterior interosseous nerve. However, there is no reliable method for restoring finger extension. In the present study, the authors examined the surgical results of transferring the supinator motor branch to the posterior interosseous nerve. Methods Since October 2007, the authors have performed a supinator motor branch transfer to the posterior interosseous nerve in 4 patients. The patients underwent follow-up every 3–4 months postoperatively. Results Finger extension appeared between 5 and 9 months in the first 3 cases and demonstrated promising improvement over time. One recent case remains under follow-up. Conclusions A supinator motor branch to posterior interosseous nerve transfer leads to reliable recovery of thumb and finger extension. Therefore, it is a viable option for C7–T1 brachial plexus palsies.

OBJECT The objective of this study was to report the results of pronator quadratus (PQ) motor branch transfers to the extensor carpi radialis brevis (ECRB) motor branch to reconstruct wrist extension in C5–8 root lesions of the brachial plexus. METHODS Twenty-eight patients, averaging 24 years of age, with C5–8 root injuries underwent operations an average of 7 months after their accident. In 19 patients, wrist extension was impossible at baseline, whereas in 9 patients wrist extension was managed by activating thumb and wrist extensors. When these 9 patients grasped an object, their wrist dropped and grasp strength was lost. Wrist extension was reconstructed by transferring the PQ motor to the ECRB motor branch. After surgery, patients were followed for at least 12 months, with final follow-up an average of 22 months after surgery. RESULTS Successful reinnervation of the ECRB was demonstrated in 27 of the 28 patients. In 25 of the patients, wrist extension scored M4, and in 2 it scored M3. CONCLUSIONS In C5–8 root injuries, wrist extension can be predictably reconstructed by transferring the PQ motor branch to reinnervate the ECRB.

The accessory nerve and the motor branch of the cervical plexus have been used as donor nerves in neurotisation procedures for brachial plexus palsy. However, there are few reports in the literature that describe their anatomy in detail. The aim of this study is to delineate the applied anatomy of these nerves. We emphasise their course in the posterior triangle of the neck as well as within the trapezius muscle. Fourteen cadavers were dissected. We identified nerves not reported before and they are the lateral cutaneous branches of C3 and C4. The deep branch of C4 is present in all the cases; it supplies the trapezius muscle and we believe it contains motor fibres. The accessory nerve gives a branch in the neck in only one case. The accessory nerve joins the deep branch of C4 in 93.3% of the cases. Clinical implications of the findings would be discussed.
