Objective To explore the clinical application of the flap supported by perforating branch of the radial artery superior wrist catena-form blood vessel in repairing hand and wrist wound. Methods Between March 2010 and March 2013, 24 cases of severe wounds in wrist were repaired with the flap supported by perforating branch of forearm radial artery and catena-form blood vessel. There were 15 males and 9 females, aged 19-54 years (mean, 37 years). In 22 patients with trauma, there were 9 cases of machine injury, 5 cases of traffic accident injury, 5 cases of crash injury of heavy objects, 1 case of sharp instrument injury, and 2 cases of electrical injury, with a mean disease duration of 11 days (range, 2-20 days). In 2 patients with tumor excision wound, there were 1 case of right forearm liposarcoma and 1 case of left forearm squamous-cell carcinoma, with the disease duration of 7 days and 3 months, respectively. All cases complicated by bone and tendon exposure. The size of defect was 4.5 cm×4.0 cm to 10.0 cm×7.5 cm, and the size of the flap was 6.0 cm×4.0 cm to 20.0 cm×8.5 cm. The donor site was directly sutured or repaired by skin graft. Results Partial flap necrosis occurred in 1 case, and was cured after dressing change; the other flaps survived, and primary healing of incision was obtained. The patients were followed up 6-36 months (mean, 20 months). The flap featured good color and texture, and also recovered protective sensation at 6 months after operation, with a mean two-point discrimination of 12 mm (range, 11-14 mm). No ulcers of the flap was observed. At last follow-up, according to Hand Surgery Society of Chinese Medical Association for functional evaluation of upper limb, the function was rated as excellent in 19 cases, good in 4 cases, and fair in 1 case. Conclusion The flap supported by perforating branch of forearm radial artery and catena-form blood vessel can be used to repair wound in wrist, which has no injury to the radial artery, and it also could be used for the patients with ulnar and radial artery injuries. Thus it is an ideal method to repair wound in the wrist because the operation is simple, and the flap has good appearance and texture.
