Abstract:
Objective:To explore the effect of the treatment of tendinous mallet finger deformity by the minimally invasive percutaneous quantitative suture technique eight times.Methods:A retrospective analysis was performed on patients with fresh tendinous mallet fingers who underwent surgery in the Department of Hand and Foot Microsurgery of Nanjing Jiangbei Hospital from April 2021 to April 2022. During the procedure, the extensor digitalis tendon in the zone Ⅰ was sutured percutaneous with 3-0 thread monofilament sutures in the "quantitative 8-stitch method" according to the pre-marked number sequence of 1 to 8, and fixed at the base of the distal phalanx via a constructed bone tunnel. Removal of the Kirschner wire 8 weeks, the brace was used to fix the affected finger in the dorsal extension. The flexion and extension of the affected finger were gradually strengthened. The function of the affected finger was evaluated according to the Crawford standard after operation and follow-up: the active flexion and extension range of motion of each joint of the affected finger and the contralateral healthy finger was measured, and the total active ranges of motion of the finger were recorded. Finger function was evaluated according to the total active range of motion (TAM) system of the American Association of Hand Surgeons.Results:A total of 10 patients (10 digits) were enrolled, including 7 males and 3 females, and the age ranged from 20 to 52 years old, with an average age of 36.5 years old. The distance of tendon break was ≤10 mm. The operation time of the patients was 20-30 min, with an average of 24.5 min. The intraoperative blood loss was minimal. All 10 cases were followed up and the follow-up period was 6 to 12 months, with an average of 7 months. Mallet finger deformities were all corrected postoperatively, dorsal skin of fingers without a scar, there were no knot exposure, skin necrosis and other complications. At the last follow-up, the mean active range of motion of the distal interphalangeal joint was 84.4° and the mean TAM of the injured finger was 265.6°. According to TAM system assessment criteria: 8 cases were excellent, and 2 cases were good.Conclusions:Satisfactory therapeutic outcome for the treatment of tendinous mallet finger deformity can be achieved by the minimally invasive percutaneous quantitative suture technique eight times. It is a simple, safe, and effective method with minimal invasion.
