Abstract:
Objective:To explore the clinical efficacy of the first dorsal metatarsal artery pedicled lateral toe bilobed flap in repairing the finger pulp defects of two adjacent fingers.Methods:This study was a retrospective observational study. From January 2018 to December 2022, 9 patients with finger pulp defects in two adjacent fingers who met the inclusion criteria were admitted to the Department of Burns and Plastic Surgery of the 988 th Hospital of Joint Logistics Support Force of PLA, including 6 males and 3 females, aged 26 to 48 years. The injured fingers were the index finger and middle finger (5 cases) or the middle finger and ring finger (4 cases). After debridement, the wound area of a single finger ranged from 1.2 cm×0.8 cm to 3.2 cm×2.8 cm. The finger pulp defects of two adjacent fingers were repaired with the first dorsal metatarsal artery pedicled lateral toe bilobed flap, and the two adjacent fingers were sutured together. The area of single flap ranged from 1.5 cm×1.0 cm to 3.5 cm×3.0 cm. The wound in the flap donor site was sutured directly or repaired with full-thickness skin graft from the groin region. The finger separation surgery was performed 3 weeks after surgery. The survival and blood supply of flaps, and survival of skin grafts and wound healing of the donor sites were observed after surgery. During follow-up, the texture, sliding, and shape of the flap, movement function of the finger, and the shape and function of the foot donor site were observed. At the last follow-up, the sensory of the flap was evaluated according to the sensory evaluation standard of the British Medical Research Council, and the hand function was evaluated according to the functional evaluation trial standard for severed finger replantation of the Hand Surgery Society of the Chinese Medical Association. Results:After surgery, all the flaps of 9 patients survived without vascular crisis. The flaps were soft in texture and good in shape. One patient had partial necrosis at the edge of the skin graft in the toe, and the wound healed after dressing change; the skin grafts in the toe in the other 8 patients survived, and the wounds healed well. During follow-up of 12 to 18 months after surgery, the flaps had soft texture, good elasticity, low sliding, and good shape. The finger movement function was normal. The wound in foot donor site recovered well without ulceration and deformity, and walking was not affected. At the last follow-up, the sensation of the flaps was sensitive, of which 8 flaps reached S3 and 10 flaps reached S3 + in sensation, and the two-point discrimination distance of the flaps was 9-13 mm. The functional scores of the affected fingers were 85 to 95, all of which were excellent. Conclusions:The first dorsal metatarsal artery pedicled lateral toe bilobed flap can repair finger pulp defects of two adjacent fingers at the same time, and the appearance, sensation, and function of the affected fingers recovered well after surgery, with less damage to the foot donor site. It is one of good methods to repair finger pulp defects of two adjacent fingers in clinic.
