ABSTRACT
Objective:
To investigate the effectiveness of finger reconstruction using nail flap anastomosing the nerve branch of the first toe nail bed.Methods:
Between January 2016 and December 2022, 18 patients (18 fingers) with thumb or finger nail bed defects were admitted. There were 12 males and 6 females, with an average age of 32 years (range, 19-42 years). Four cases were finger tip tissue damage caused by machine compression, and 4 cases were distal tissue necrosis after finger replantation. There were 9 cases of thumb injury, 3 cases of index finger injury, 5 cases of middle finger injury, and 1 case of ring finger injury. There were 11 cases of distal nail damage and 7 cases of distal nail root (including nail root) damage. The time from injury to admission was 1-5 hours, with an average of 2 hours. After debridement and anti-infection treatment for 5-7 days, the wounds in size of 1 cm×1 cm to 4 cm×3 cm were reconstructed by using nail flaps anastomosing the nerve branches of the first toe nail bed. The size of the nail flaps ranged from 1.5 cm×1.5 cm to 4.5 cm×3.5 cm. The donor sites were repaired with the flaps in 16 cases and skin graft in 2 cases.Results:
All nail flaps, flaps, and skin grafts survived after operation and the wounds healed by first intention. All patients were followed up 6-12 months (mean, 10 months). The nails of 18 cases were all grown, in which 16 cases had smooth nails with satisfactory appearances, 1 case had uneven nails, and 1 case had obvious scar hyperplasia around the suture opening. At 6 months after operation, the two-point discrimination of the skin flap was 4-8 mm (mean, 6 mm). Meanwhile, the skin grafts and flaps at the donor sites regained protective sensation, good abrasion resistance, and had no negative effect upon walking and wearing shoes.Conclusion:
The application of a nail flap that anastomoses the nerve branch of the first toe nail bed for finger reconstruction has minimal damage and can achieve good nail bed repair results.Key words
