- MEDIAN NERVE FASCICLE TRANSFER VERSUS ULNAR NERVE FASCICLE TRANSFER TO THE BICEPS MOTOR BRANCH IN C5-C6 AND C5-C7 BRACHIAL PLEXUS INJURIES: NONRANDOMIZED PROSPECTIVE STUDY OF 23 CONSECUTIVE PATIENTS(2014) CHO, Alvaro Baik; PAULOS, Renata Gregorio; RESENDE, Marcelo Rosa de; KIYOHARA, Leandro Yoshinobu; SORRENTI, Luiz; WEI, Teng Hsiang; BOLLIGER NETO, Raul; MATTAR JUNIOR, RamesThe purpose of this study was to observe whether the results of the median nerve fascicle transfer to the biceps are equivalent to the classical ulnar nerve fascicle transfer, in terms of elbow flexion strength and donor nerve morbidity. Twenty-five consecutive patients were operated between March 2007 and July 2013. The patients were divided into two groups. In Group 1 (n=8), the patients received an ulnar nerve fascicle transfer to the biceps motor branch. In Group 2 (n=15), the patients received a median nerve fascicle transfer to the biceps motor branch. Two patients with follow-up less than six months were excluded. Both groups were similar regarding age (P=0.070), interval of injury (P=0.185), and follow-up period (P=0.477). Elbow flexion against gravity was achieved in 7 of 8 (87.5%) patients in Group 1, versus 14 of 15 (93.3%) patients in Group 2 (P=1.000). The level of injury (C5-C6 or C5-C7) did not affect anti-gravity elbow flexion recovery in both the groups (P=1.000). It was concluded that the median nerve fascicle transfer to the biceps is as good as the ulnar nerve fascicle transfer, even in C5-C7 injuries. (C) 2014 Wiley Periodicals, Inc.
