Abstract:
Objective:To explore the clinical effects of modified anterograde homodigital neurovascular island flap for repairing soft tissue defects in the distal part of the finger.Methods:The data of patients with fingertip defects in the Department of Hand and Foot Surgery, the First Affiliated Hospital of Wannan Medical College from September 2019 to June 2021 were analyzed retrospectively. All the patients were treated with double V-Y designed modified anterograde homodigital neurovascular island flaps. The survival of these flaps and wound healing were observed after operation. At the last follow-up, sensibility of the flap was assessed. Hand function was evaluated according to the upper limb function evaluation standard of the Chinese Society of Hand Surgery.Results:The patients comprised 12 males and 3 females with an average age of 46 years (26-67 years). Single-finger defects were noted in all cases. The injured included 7 thumbs, 4 index fingers, 2 middle fingers, 1 ring finger, and 1 little finger. The area of wound defect was 1.0 cm×1.0 cm-1.3 cm×1.4 cm. All flaps survived in 15 cases and the wounds healed well. All cases were followed up 6-12 months (mean, 8.9 months). At last follow-up visited, the discrimination distance between the two points was 4-6 mm (mean, 5.1 mm), and the hand function was excellent in 9 cases and good in 6 cases.Conclusions:The modified anterograde homodigital neurovascular island flap has reliable blood supply, long advance distance and satisfactory sensation recovery, which is an effective method for reconstructing small-size finger tip defects.
