Abstract:
Objective:To explore the clinical effect of repairing the ankle soft tissue defects with bone exposure using descending branch of lateral circumflex femoral artery (LCFA-db) perforator flap.Methods:From May 2014 to March 2018, 11 patients with ankle soft tissue defect with bone and tendon exposure were treated in the First Central Hospital of Baoding City ( 9 males and 2 females, aged from 19 to 47 years). VSD treatment was performed after debridement. When the wound show no signs of infection, the secondary repair was performed using the LCFA-db perforator flap. The area of the flap was 6.5 cm×4.5 cm-16.5 cm×8.5 cm. Followed-up was acquired to be used for evaluating the clinical effect.Results:There were no complications such as vasospasm or vascular crisis for transplanted flap after surgery. In 11 cases, 2 cases had necrosis of 0.5-1.0 cm in the distal part of the flap. Both were completely healed after dressing and related treatment. The flaps in the rest of patients survived successfully. The patients were followed up for 4-16 months with a mean time of 10.4 months. These flaps survived with good appearance, no swelling, no need for secondary surgery, soft texture, abrasion resistant and no pigmentation. Protective sense was restored. At the last follow-up, the American Orthopedic Foot and Ankle Society Score (AOFAS) score was ranging from 74 to 98 in 11 cases with the average score of 90.55. The outcomes were excellent in 8 cases, good in 2 cases and fair in 1 case. The donor site of the flap healed well. The flexion and extension of knee joint were normal with the good appearance and no impaired function.Conclusions:LCFA-db perforator flap may serve as an alternative option for reconstructing the ankle with soft-tissue defect.
