Abstract:
Objective To provide a good anatomical foundation for transposition of the branch of median nerve superficial flexor muscle repairing the movement branch of ulnar nerve to recover the function of intrinsic muscle, by anatomic study of the muscle branch of the superficial flexor muscle of the median nerve and the movement branch of ulnar nerve. Methods Twenty adult upper limb specimens immersed fixed by formalin were elected and expose the midian nerve and ulnar nerve. Then every anatomical index was measured. Simulate to manipulate that the branch of superficial flexor muscle repair the motor b ranch of ulnar nerve. Calculate the number of myelinated nerve fibers of the branch of superficial flexor muscle. Results The distance between the position into muscle and styloid process of radius and styloid process of ulna: (21.4±1.8)mm, the distance that can be separated: (27.1±1.2)mm, the transverse diameter: (1.2±0.2)mm, anteroposterior diameter: (0.7 ± 0.1 )mm. No injury separated distance between the sensory branch and motor branch of ulnar nerve: (7.1 ± 0.7)cm. The 4th muscular branches of median nerve flexor digitorum superficialis was 1378.9± 107.9. Conclusion The 4th muscular branches of median nerve flexor digitorum superficialis can be used to repair the motor branch of the ulnar nerve to recover the function of intrinsic muscle of hand.
