Introduction: Proximal ulnar and median nerve injury result in an unfavorable outcome .the purpose of this study was to explore the possibility of sensory reconstruction of the ulnar nerve and median nerve by transfer of the superficial branch of the radial nerve.

Material and methods: Fifteen cadaver specimens were dissected at the proposed nerve coaptation site .A computer-based image analysis system was employed to analyzed the data of myelinated axon ,fascicle, nerve cross-sectional area, fascicle area of the transverse semi-thin sections

Results: The axon number ranged from 202 to 5405 with an average of 2308±528(Mean±SEM) for the superficial branch of the radial nerve (SBRN), from 152 to 7285 with an average of 3152±674 for the superficial branch of the ulnar nerve (SBUN), from 468 to 6065 with an average of 2446±668 for the sensory part of the median nerve (SMN). The nerve cross-sectional area was 1.68 ±0.46 mm2 in the SBRN, 2.07 ±0.36 mm2 in the SBUN and 2.58 ±0.77 mm2 in the SMN. Comparison of the SBRN to the SBUN and the SMN revealed that the SBRN had comparable axon number and nerve cross-sectional area to the SBUN and SMN. It makes the SBRN as a suitable donor nerve for transfer to the SBUN or the SMN.

Conclusion: Our finding of the study support the possibility of sensory-transfer for reconstruction after proximal injury of the ulnar nerve or the median nerve
