Abstract:
Objective:To investigate the method and outcome of reconstruction of thumb soft tissue defect by index finger proximal dorsal island flap supplied by the second dorsal metacarpal artery (SDMA).Methods:From August, 2015 to December, 2017, 12 cases of thumb soft tissue defect were treated by index finger proximal dorsal island flap supplied by SDMA. The site of defect ranged from 2.0 cm×2.4 cm to 5.5 cm×3.0 cm, and the flap area ranged from 2.2 cm×2.6 cm to 6.0 cm×3.3 cm. The donor site was repaired by split-thickness skin graft from the forearm of the injured limb. All patients received regular outpatient follow-up after surgery. The appearance, texture, sensory recovery and donor site of the flap were observed.Results:All the 12 flaps had 5-16 (8.8 in average) months follow-up and survived, the donor site and wounds healed in primary stage. The appearance, sensory and function of the flaps were good. There were no scar contracture on the donor sites, and no pain and limitation of motion in the joints. At the last follow-up, according to the Criteria for Function Assessment of Upper Limbs by the Branch of Hand Surgery of Chinese Medicine Association, the thumb functions were excellent in 11 cases and good in 1 case.Conclusion:Index finger proximal dorsal island flap supplied by SDMA is easy to operate, and has constant blood supply, improved rotation angle of the flap vessel base. It is a good method to repair the soft tissue defect of thumb.
