ABSTRACT
Objective:
To investigate the clinical effect of the first dorsal metatarsal-dorsal phalangeal artery flap in repairing large area of soft tissue defect on the palmar side of finger.Methods:
From February, 2016 to June, 2018, 11 fingers of 11 patients (7 males and 4 females, aged 19-46 years old with an average of 32.5 years old) with large area of soft tissue defect on the palmar side of the finger were repaired with the first dorsal metatarsal-dorsal phalangeal artery flap. These included 3 with the first dorsal metatarsal-first dorsal phalangeal artery blood supply, and 8 with the first dorsal metatarsal-second dorsal phalangeal artery blood supply. In which 3 with retained finger pulp was for repairing the defects and bridging arteries, including 1 flexor tendon defect repaired by the extensor digitorum brevis tendon of the second toe with the flap. The type of blood vessel was Gilbert I detected by CDU before surgery. The area of the flaps was from 1.5 cm×5.0 cm to 3.0 cm×8.0 cm. The donor area of the flaps was compressed with full thickness skin grafts of the shank. The follow-up data was collected by outpatient clinic visits and telephone interviews.Results:
All the 11 flaps survived and were followed-up for an average of 14 months, ranged from 6 months to 24 months. The colour and texture of the flaps were good. Sensing of temperature, pain and touch restored, without swelling. Function of the fingers was well restored. The range of motion of distal and proximal interphalangeal joints was closed to normal. The TPD of the flaps was 5-11 mm, with an average of 8 mm. Ten had primary wound healing in the donor sites of foot. One case had necrosis of the proximal toe of the skin graft and healed after dressing change. Long-term follow-up of the skin grafting area was wear-resistant, and does not hinder walking without rupture.Conclusion:
Application of the first dorsal metatarsal-dorsal toe artery flap to repair large area of soft tissue defect on the palmar side of finger has number of advantages such as it, covers the wound and carry the tendons, bridges the arteries at the same time, plus delivers satisfactory outcome.
