Abstract:
Objective:To explore the clinical effects and value for application of the tibial flap of the second toe with the vascular pedicle including a plantar vein on the reconstruction of fingertip soft tissue defects.Methods:From October 2020 to August 2022, retrospective analysis of 12 patients (12 digits) were treated at the Department of Hand Surgery, Suzhou Ruihua Orthopaedic Hospital for small soft tissue defects of fingertip. The patients were 9 males and 3 females and aged 29-54 years, at 38 years in average. The fingertip defects were measured at approximately 1.2 cm × 0.8 cm to 1.2 cm × 1.2 cm. In the surgery, a tibial flap of second toe was designed to reconstruct the defect in fingertip. The flap were designed on the tibial of second toe without an extended incision in dorsal foot. The pedicle of the flap carried with the lateral proper digital artery, a nerve and the plantar vein of the second toe. At the recipient site, the artery, nerve and vein carried by the pedicle of the flap were end-to-end anastomosed with the digital artery, digital nerve and subcutaneous vein of the finger. The flaps were measured at 1.5 cm×1.0 cm - 1.5 cm×1.5 cm in size. All donor sites were reconstructed with skin grafts from the ipsilateral calf. Scheduled postoperative follow-ups were conducted at the outpatient clinic. The Michigan Hand Function Questionnaire (MHQ) evaluation criteria was employed to assess the recovery of hand function, and Total Active Movement (TAM) was used to evaluate the recovery of range of motion of the interphalangeal joints of the affected fingers.Results:All 12 flaps in the fingertips survived. Postoperative follow-ups lasted from 6 months to 2 years, with an average of 11 months. One flap was slightly bloated and a flap aesthetic surgery was followed at 3 months after the primary reconstructive surgery, and the rest of flaps were all in good appearance. TPD was found at 12 -14 mm for all flaps at 9 months after surgery. All donor sites in the feet and calfs had primary healing, without a contracture or rupture of skin graft or an obvious dysfunction at the donor sites. According to the evaluation criteria of the MHQ, 8 patients were very satisfied with the overall appearance of the hand, and 4 were satisfied. Finger movement was evaluated according to TAM criteria, all 12 fingers were rated excellent.Conclusion:Reconstruction of a fingertip defect with a tibial flap of the second toe with the vascular pedicle including a plantar vein of the second toe has a good clinical efficacy. It has advantages in flap harvest, avoids an extended incision on dorsal foot, and makes a minimal damage to the donor site.
