Abstract
Sometimes serious tension occurs in the radial nerve when doing internal fixation for distal humerus shaft fracture or neurorrhaphy for radial nerve injury. Medial transposition of radial nerve on fracture site can avoid direct radial nerve injury by fracture fragment, radial nerve tension by plating for distal humerus shaft fracture, and also safe from neural tension during neurorrhaphy of damaged radial nerve. We reported here total 6 cases of backward transposition of radial nerve including 2 cases of radial nerve injury associated with humerus fracture and 4 cases of comminuted fracture of humerus shaft.

(A) Clinical photograph showing complete rupture of radial nerve with nerve gap.
(B) After removal of plate & screws, 2 cm nerve gap was found.
(C) After sufficient mobilization, and neurorrhaphy of ruptured radial nerve through fracture site, the nerve (arrow) was transposed on backside of humerus without tension.
