Abstract:
Objective:To investigate the clinical effect of anterolateral thigh perforator flap (ALTPF) combined with transfer of fascia lata in reconstruction of complex tissue defects of hand and foot.Methods:From July 2021 to October 2023, 9 patients with complex tissue defects of hand and foot were treated with ALTPF combined with fascia lata in the Department of Orthopaedic Microsurgical Repair and Reconstruction of Fuyang People's Hospital Affiliated to Anhui Medical University. There were 2 males and 7 females with an average age of 28.1 (range, 4-65) years old. Three patients had extensor tendon defects in 6 digits of dorsal hands, 5 had extensor tendon defect in 10 toes of dorsal foot, 1 had a defect of anterior tibial tendon and 1 had Achilles tendon defect in posterior ankles. The sizes of soft tissue defect ranged from 8.0 cm×6.0 cm to 15.0 cm×10.0 cm, and the lengths of tendon defect ranged from 6.0 to 13.0 cm. Preoperative Doppler ultrasound was used to locate the distribution of perforating branches in the anterolateral thigh region. According to the characteristics of wound, ALTPFs and fascia lata were designed and harvested. Fascia lata with an appropriate size of 1.5 cm×8.0 cm-4.5 cm×15.0 cm were taken to bridge the defects of the tendon and the Achilles tendon. The wounds were reconstructed with flaps sized 9.0 cm×6.5 cm-18.0 cm×7.5 cm. Nine fascia lata donor sites and 8 flap donor sites were sutured directly. One donor site was treated with a skin graft of ipsilateral ilioinguinal region. The survival and complications of the flaps and donor sites were observed through outpatient follow-up visits, WeChat reviews and home visits, etc. The hand function was assessed according to the Evaluation Standard of Upper Limb Functional of Hand Surgery of Chinese Medical Association, and the foot and ankle function was assessed according to the Mazur score standard of joint range of motion and motor function.Results:All patients were included in follow-up for 4-24 (mean, 13.4) months with complete clinical data being collected. All 9 ALTPFs survived and healed primarily. A linear scar left in donor sites in 8 patients, and mild lamellar scar at skin graft in 1 patient. Texture and colour of the flaps were similar to the surrounding tissue without secondary flap thinning surgery. Combined with postoperative rehabilitation training, satisfactory function recoveries were achieved. Hand function of 3 patients were evaluated according to Evaluation Standard of Upper Limb Functional of Hand Surgery of Chinese Medical Association, 2 patients were excellent and 1 was good. Ankle and foot functions in 6 patients were evaluated according to the range of motion of ankle and foot and Mazur score standard for motor function, 4 patients were excellent and 2 were good.Conclusion:ALTPF combined with fascia lata transfer can reconstruct the complex tissue defects of hand and foot. Of which, 1 donor site can meet the requirements of 2 types of tissues reconstruction at the same time, and with minimal damage to the donor site as well as an precise reconstruction of the recipient site. It avoids staged surgery, shortens the treatment time and reduces the cost of treatment.
