Distal Finger Reconstruction by Bilateral Lateral Hallux Osteo-onychocutaneous Free Flap.
ANNALS OF PLASTIC SURGERY(2019)
摘要
Objective: In this report, we present our experience on the use of bilateral lateral hallux osteo-onychocutaneous free flaps for reconstruction of distal finger and the aesthetic and functional results of this technique in a series of cases. Patients andMethods: From February 2005 to May 2015, 7 patients underwent finger reconstruction distal to the distal interphalangeal joint using the bilateral lateral hallux osteo-onychocutaneous free flaps. The mean age was 29.3 years (range, 24-33 years). The lateral hallux osteo-onychocutaneous flaps were harvested from bilateral donor sites. The size of each flap was designed based on the size of half distal finger defect. The lateral hallux osteo-onychocutaneous free flaps from both donor sites were combined to reconstruct the distal finger. More than 50% of hallux nail was preserved in each of donor sites, which was covered with a local flap. Results: All flaps used for reconstruction survived without complications after surgery. The average length of follow-up was 93.4months (range, 16-163months). All reconstructed distal fingers showed good aesthetic appearance, except one that underwent a secondary debulking procedure. The average total active motion of the finger was 215.7 degrees (range, 200-230 degrees). Neither pain nor numbness sensation in the reconstructed fingers was complained by the patients. The donor site morbidity was minimal. All patients had pain-free and good function outcome in both feet. Conclusions: The use of the bilateral lateral hallux osteo-onychocutaneous free flaps may provide an option for distal finger reconstruction with satisfactory function and anesthetic outcomes with minimal hallux donor site morbidity.
