ABSTRACT
Between 1993 and 1998, 32 male patients with brachial plexus injuries were surgically
treated. Eighteen interfascicular grafting and 71 extraplexal neurotization procedures
were performed separately or in combination. Donor nerves were the intercostals, spinal
accessory, phrenic, contralateral C7, and cervical plexus, in order of frequency.
Patients were followed for a minimum of 24 (average, 35) months. Biceps function was
best following grafting the musculocutaneous nerve itself, or neurotization with the
phrenic nerve (100 percent grade 4), followed by neurotization with the intercostals
(89.5 percent grade 3 or more) and last, grafting the C5 root or upper trunk (grade
3 in one of three patients). Phrenic to suprascapular neurotization produced the best
results of shoulder abduction (40 to 90 degrees), followed by combined neurotization
of the spinal accessory to suprascapular and phrenic to axillary (20 to 90 degrees).
Sensory recovery over the lateral forearm and palm varied from S2 to S3+, according
to the method of reconstruction.
