Objective To investigate the clinical application of the forearm interosseous dorsal artery perforator sublobe flaps in repairing two wounds in dorsal hand or wrist. Methods Between October 2009 and October 2012, 12 patients with two wounds in the dorsal hand or wrist were included in the study. There were 4 cases of skin defects (grade IV) and bone exposure caused by machine injury, 3 cases of skin defects with bone and tendon exposure caused by traffic accident, and 3 cases of skin defect and tendon exposure caused by crash injury of heavy object, with a duration of 3-12 hours (mean, 6 hours) between injury and admission; defects in the wrist and tendon exposure were caused by tumor resection in 2 cases. Four cases had metacarpal fractures. The size of larger skin and soft tissue defects ranged from 4.0 cm×3.5 cm to 5.0 cm×3.0 cm, and the size of smaller defects was from 2.5 cm×2.0 cm to 4.0 cm×3.0 cm. The flap size was from 6 cm×4 cm to 8 cm×3 cm and 3.0 cm×2.5 cm to 5.0 cm×3.0 cm. The donor sites were directly sutured or repaired with free skin graft. Results All the flaps survived, and wound healed in first stage. All the cases were followed up 6-36 months (mean, 20 months). The flaps had good color and texture. Three cases underwent secondary surgery of thinning the flaps. At last follow-up, two-point discrimination of flaps was 10-14 mm, 12 mm on average. According to function standard for evaluation of upper extremity with total active motion of the fingers from the Hand Surgery Society of Chinese Medical Association, the results were excellent in 10 cases, and good in 2 cases. Conclusion Forearm interosseous dorsal artery perforators sublobe flaps can be used to repair two wounds in the dorsal hand or wrist simultaneously, and it has the advantages of simple operation, less injury at donor site, and reliable blood supply.
