Abstract:
Objective:To summarize the effect of reverse homodigital dorsal thumb flap in repairing thumb pulp defect.Methods:A retrospective case series study was conducted to analyze the clinical data of patients with thumb pulp defects admitted to the People's Hospital of Renqiu from March 2010 to June 2020. The dorsal homodigital island flap of the proximal phalanx was designed and harvested. During the procedure, the proximal digital artery of the perforator vessels of the flap was cut off and ligated. The digital artery pedicled flap was retrograde transferred to cover the thumb pulp defect. 9-0 line was used to anastomose the dorsal digital nerve with the proper digital nerve. The donor site was repaired with a free skin graft.Results:A total of 68 cases of thumb pulp defects were enrolled, all of whom were accompanied by exposure of the tendon of the distal phalanx. There were 39 males and 29 females, aged from 18 to 63 years (average of 35.8 years). The size of the proximal dorsal island flap was 2.0 cm × 3.0 cm to 3.1 cm × 4.2 cm. All flaps and skin grafts survived, and wounds healed primarily. All patients were followed up for 6 to 28 months (mean, 10.6 months). The color, texture, and contour of the flaps were good. All repaired thumbs got the normal function of extension and flexion. At the last follow-up, the two-point discrimination of flaps was 4-11 mm.Conclusions:It has the advantages of small trauma, simple operation, and good curative effect, using the homodigital dorsal thumb flap to repair the thumb pulp defect.
