Additional Option

Nerve transfer between the spinal accessory nerve (SAN) and the suprascapular nerve (SSN) is a standard technique in shoulder reanimation. In cases of global brachial plexus injury, donor nerves are few and at times severely traumatized owing to extensive traction forces. This precludes the application of standard nerve transfer techniques. The authors offer the use of the contralateral SAN as an additional option in the reinnervation of an injured SSN in such circumstances. To the best of their knowledge, this is the first successful attempt of this technique to be reported in the literature.

Background Optimal dynamic reconstruction of shoulder function requires a functional suprascapular nerve (SSN). Nerve transfer of the distal spinal accessory nerve (dSAN) to the SSN will in many cases restore very good supraspinatus and infraspinatus function. One potential cause of failure of this nerve transfer is an unrecognized more distal injury of the SSN. An anterior approach to this transfer does not allow for visualization of the nerve at the scapular notch which is a disadvantage when compared with a posterior approach to the SSN. Methods All patients of the senior author (S.F.) with traumatic brachial plexus injuries undergoing spinal accessory nerve to SSN transfer via the posterior approach were analyzed. Results Of the 58 patients, 11 (19.0%) demonstrated abnormal findings at the notch. In two of these 11 patients (18.2%), reconstruction was abandoned due to severe injury of the nerve. There was a higher rate of clavicular fractures in patients with SSN injuries at the notch, compared with no SSN injury at the notch (63.6 vs. 12.8%). Conclusion The dSAN to SSN transfer is a reliable reconstruction for restoration of shoulder external rotation and abduction. There is a high proportion of injuries to the nerve at the notch, which can be best appreciated from a posterior approach. The authors, therefore, advocate a posterior approach for this nerve transfer.

Single Donor

In upper (C5-C7) and total (C5-T1) root avulsion brachial plexus injury, a method of double neurotization from a single donor spinal accessory nerve to two target nerves (suprascapular nerve and axillary nerve) may be done, leaving donor nerves available for reconstruction procedures to restore other aspects of upper limb function. A mean range of shoulder abduction of 91° (SD 25°) was achieved through this procedure in our study of 13 cases, of which seven cases were C5-C7 root avulsion and six cases were C5-T1 root avulsion brachial plexus injuries. Six of the former group and three of the latter group achieved >90° shoulder abduction. The technique of double neurotization from a single donor nerve provides favourable results in restoring shoulder abduction in avulsion brachial plexus injuries. Level of evidence: IV
