Objective  To investigate the effectiveness of latissimus dorsi Kiss flap for repairing composite tissue defects and functional reconstruction of upper arm. Methods  Between March 2010 and November 2016, 12 cases of composite tissue defects of upper arm were repaired by latissimus dorsi Kiss flap with blood vessel and nerve bunch. There were 8 males and 4 females with a median age of 34 years (range, 21-50 years). The reason of injury included plowing mechanical injury in 4 cases, traffic accident injury in 5 cases, electrical injury in 2 cases, and resecting upper arm soft tissue sarcoma in 1 case. There were deltoid defect in 5 cases, triceps brachii and brachialis defect in 4 cases, and deltoid, triceps brachii, and brachialis damaged in varying degrees in 3 cases. The defect area ranged from 13 cm×7 cm to 20 cm×8 cm. Among them, there were 6 cases of fracture combined with partial bone exposure, one of them with bone defect. The disease duration was 3 hours to 6 months. The flap size ranged from 10 cm×6 cm to 15 cm×7 cm, and the donor sites were directly sutured. Results  Twelve flaps survived with primary healing of wounds. Ten patients were followed up 6-26 months (mean, 14 months). At last follow-up, the flaps were soft and the skin color was similar to the surrounding skin. No obvious scar was found at donor sites. The abduction range of motion of shoulder was 30-90°. The muscle strength of brachialis were all at grade 4 or above. The superficial sensation and tactile sensation recovered partialy (S1 in 2 cases, S2 in 6 cases, S3 in 2 cases). According to Society of Hand Surgery standard for the evaluation of upper part of the function, the shoulder joint function was excellent in 2 cases, good in 4 cases, and fair in 4 cases. Conclusion  The design of the latissimus dorsi Kiss flaps are flexible, and the donor site can be directly sutured, with the nerves of the latissimus dorsi muscle can partialy reconstruct abduction function of upper arm. In general, the Kiss flap repairing upper arm defect can obtain satisfactory effectiveness.
