  • ANATOMICAL STUDY AND CLINICAL APPLICATION OF LONG HEAD OF TRICEPS MUSLE FOR RECONSTRUCTION OF SHOULDER ABDUCTION

    OBJECTIVE: To study the morphological character of long head of triceps muscle for clinical application in reconstruction of shoulder abduction. METHODS: Forty-four upper extremities of fixed human adult cadavers were carefully dissected. The origins and the pedicles of blood vessels and nerves of long head of triceps muscle, as well as the maximum available size of the muscles, were measured. Six cases of clinical application of long head of triceps muscle for reconstruction of shoulder abduction were followed up for 3 to 11 months. RESULTS: The origins in the dorsal side of long head of triceps muscle were muscular and the ventral side were tendinous, which was 7.6 to 13.3 cm in length and 1.6 to 3.4 cm in width. The distance from the origin to the neurovascular pedicle was 5.7 to 11.4 cm. The radial nerve, which innervated the muscles, could be dissected for 2.9 to 11.8 cm in length. The blood supplies to the triceps muscle were from humeral artery (43.2%), 1.0 to 6.0 cm in length and 1.6 to 2.4 mm in diameter, and from humeral profundus artery (45.5%), 1.5 to 4.4 cm in length and 0.9 to 2.4 mm in diameter, if the vessel was separated to the humeral artery, the length was 1.5 to 6.3 cm. The neurovascular pedicles were multiple branched. In the 6 cases of clinical application of the triceps muscles, the operated shoulder could abduct from 5 degrees preoperatively (0 degree to 10 degrees) to 77.3 degrees (50 degrees to 90 degrees) postoperatively. CONCLUSION: In accordance to the anatomical character of the triceps muscles, the long head of triceps muscle is a suitable choice for reconstruction of shoulder abduction with optimistic outcomes.

  • COMPRESSION OF THE DEEP BRANCH OF ULNAR NERVE AT THE WRIST

    OBJECTIVE To investigate the compression factor and clinical manifestation of the compression of deep branch of the ulnar nerve at the wrist. METHODS Anatomic study was done on both sides of 10 cadavers, the deep branch of ulnar nerve, the Guyon’s canal and the flexor digiti minimi brevis pedis were observed. Then from Jan. 1990 to Jan. 1997, 5 patients with compression of the deep branch of ulnar nerve at the wrist were treated clinically. Among them, there were 4 males and 1 female, aged from 37 to 48 years and the course of disease ranged from 1 to 5 months. RESULTS The motor branch of the ulnar nerve passed under the tendinous arcade of flexor digiti minimi brevis pedis. Occasionally, the branch of ulnar artery overpassed the motor branch. Clinically, the tendinous arcade compressed the motor branch was released, and after 2 to 4 years follow-up, the clinical results were satisfactory. CONCLUSION The main compression factor of the ulnar nerve at the wrist is the tendinous arcade of the flexor digiti minimi brevis pedis, the tendinous arcade should be released sufficiently during the operation.
