Comparative StudyReliability of functioning free muscle transfer and vascularized ulnar nerve grafting for elbow flexion in complete brachial plexus palsy.
We compared outcomes of primary vascularized ulnar nerve grafts from the C5 root neurotizing biceps and brachialis muscles, and gracilis functioning free muscle transfer neurotized by the distal spinal accessory nerve, as a primary or salvage procedure after complete brachial plexus injury. At 45 months, three of eight primary vascularized ulnar nerve graft patients regained grade 4 elbow flexion, while one regained grade 3. ⋯ Although vascularized ulnar nerve graft-based primary reconstructions can provide useful elbow flexion, this was achieved in less than half the cases. We consider primary gracilis functioning free muscle transfer neurotized by the distal spinal accessory nerve as the most reliable reconstruction for the restoration of elbow flexion in complete brachial plexus injury.

Case ReportsRestoration of shoulder abduction in brachial plexus avulsion injuries with double neurotization from the spinal accessory nerve: a report of 13 cases.
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.

The natural history of recovery of elbow flexion after obstetric brachial plexus injury managed without nerve repair.
In this study, we report the outcome for spontaneous recovery of elbow flexion in obstetric brachial plexus injury managed without nerve reconstruction. Excluding those with transient paralysis, our records revealed 152 children with obstetric brachial plexus injury born before our unit routinely offered brachial plexus reconstruction. Five had had nerve repairs. ⋯ The mean isometric elbow flexion strength, in 39 patients, was 63% (range 23%-100%) of the normal side. It appears to be rare for elbow flexion not to recover spontaneously, although recovery occurs later in more severe injuries. It is doubtful if nerve reconstruction can improve elbow flexion above the likely spontaneous recovery in babies with obstetric brachial plexus injuries.
