ObjectiveTo study the clinical effect of thenar flap in repair of finger skin defect or phalanx exposed wounds. Methods31 cases with distal fingers skin defect or phalanx exposed wounds were divided into control group (15 cases) and observation group (16 cases). Patients of the control group received finger artery retrograde island flap repair; and patients of observation group were treated with thenar flap repair treatment. After operation, patients of the two groups were given anti-infection and symptomatic treatment; 2 weeks after surgery the wound stitches were removed. Clinical effect and healing of wounds were compared between the two groups. ResultsAfter wound healing, the skin flap color and appearance were not significant difference with the wounded fingers; the wounded fingers had satisfactory appearance, skins were not damaged and fester. After postoperative functional exercise, the wounded fingers obtained excellent grip function. In the observation group, the wound healing was good in 4 cases and excellent in 11 cases; 1 case with distal flap or small superficial area of necrosis, the wound gradually healed after dressing. In control group, 8 cases were excellent, 1 cases were good, 6 cases were poor. The good and excellent rate of observation group was 93.8% (15/16), significantly higher than that of control group 60% (9/15), the difference was statistically significant (P＜0.05). ConclusionThenar flap for repair of finger skin defect or bone exposed wound, is simple and effective, safe, can remain the fingertip appearance and function of injured fingers.
