Abstract:
Objective:To summarise the clinical application and results of superficial peroneal artery perforator flaps in tiled reconstruction of thumbs and fingers.Methods:From June 2020 to June 2022, 8 patients with finger or thumb defects (4 thumbs, 2 index fingers and 2 middle fingers) received digit reconstruction in the Department of Hand Surgery, Suzhou Ruihua Orthopaedic Hospital. Two thumbs (2 patients) were reconstructed with a free partial hallux nail flap combined with a free perforator flap of superficial peroneal artery and an iliac bone graft, 1 thumb was reconstructed with a free partial hallux nail flap combined with a free perforator flap of superficial peroneal artery, 1 thumb and 2 middle fingers were reconstructed with free perforator flaps of superficial peroneal artery combined with iliac bone grafts, and 2 index fingers were reconstructed with lobulated free perforator flaps of superficial peroneal artery. The sizes of the flaps were 1.8 cm×3.2 cm-4.0 cm×10.0 cm. Lengths of iliac crest were 1.5-4.0 cm. The donor sites were directly sutured in 5 patients, skin grafts in 2 and superficial peroneal artery perforator flap reconstruction in 1 patient. Postoperative observations included survival of the digits and healing of the bone grafts. Monthly scheduled postoperative follow-ups were conducted at outpatient clinics and via telephone or WeChat reviews, covering function and appearance of the reconstructed digits, impact on the function and appearance of donor sites as well as the satisfaction of patients.Results:All 8 reconstructed digits survived in one stage and all the 5 bone grafts healed at 3 to 4 months after surgery. The mean postoperative follow-up period was 10 months, ranged 4 to 20 months. The texture of the reconstructed digits was close to that of the recipient site and good in elasticity, without purplish while in cold, nor ulceration, obvious bloating and pigmentation. Sensation of the digit pulps was recovered to S 2 to S 3, and the sensation in touch, pain and temperature were restored. TPD was not checked. There was no noticeable hyperplasia nor pain in the recipient and donor sites. There was no obvious hyperplasia or pain at the donor sites for the hallux nail flap, and the skin grafts or flaps in the donor sites survived well without ulceration or pain and the function of the donor feet were not affected. Functions of the reconstructed digits were assessed according to the Functional Assessment Criteria for Thumb and Finger Reconstruction of the Society for Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, 4 patients achieved in excellent and 4 in good. According to the University of Michigan Hand Profile Questionnaire (MHQ), patient satisfaction was found very satisfied with 4 patients and satisfied with the other 4 patients. Conclusion:The superficial peroneal artery perforator flap has advantages of thin and large area with pleasant texture, better sensation recovery and less damage to the donor site. It is an ideal flap for reconstruction of thumbs and fingers.
