ABSTRACT
INTRODUCTION:
Attaining active glenohumeral external rotation (aGHER), whether via primary reconstruction or spontaneous recovery, is infrequent in patients with neonatal brachial plexus palsy (NBPI). We evaluated the effectiveness of triceps-to-teres minor motor branch transfers to restore this function, both performed primarily (i.e., in conjunction with microsurgical plexus reconstruction) or secondarily (after primary surgery has failed to restore aGHER). PATIENTS ANDMETHODS:
This was a retrospective study of 12 children with NBPI undergoing triceps-to-teres minor motor branch transfer via an axillary approach, six undergoing primary surgery and six secondary. The primary outcome was post-operative restoration of aGHER in abduction. The primary-surgery group consisted of six children of mean age 8 months (range 5-11) with partial injuries ranging from C5-C6 to C5-C8. The secondary-surgery group included six patients with C5-C6 injuries of mean age 43 months (range 23-120), undergoing re-operation a mean 40 months (range 18-116) after their primary surgery.RESULTS:
No complications occurred after surgery. At a mean follow-up of 22 months (range 14-30), aGHER in abduction only was restored in one patient in the primary group while in the secondary group, aGHER in abduction was restored in all patients to a mean 73° (range 70-80) after a mean follow-up of 16 months (range 6-26).CONCLUSIONS:
Triceps-to-teres minor motor branch transfer is not indicated as primary surgery for NBPI. However, they can be effective in children in whom primary surgery has failed to restore aGHER, even if the spinal accessory nerve is unavailable for transfer to the infraspinatus motor branch.
