Axillary to Radial Nerve Transfer for Elbow Extension in the Tetraplegic Patient: A Case Series

The ARNT provided at least M3 strength in 13 of 22 (59%) limbs. An additional 4 limbs achieved M2, providing functional benefit to the patient. Patients with a preoperative ICHST score of 3 or 4 all achieved antigravity strength overhead. No functional deficits due to donor nerve sacrifice was observed. Further investigation will be necessary to establish predictive factors for success of patients with ICHST scores 1 and 2. Overall, the ARNT is a good option for recovery of triceps function.
