Abstract：Objective To investigate the effects of the flow-through type anterolateral femoral perforators flap pedicled with the oblique branch of lateral circumflex femoral artery in repairing wound on the back of the hands caused by hot pressure injury.Methods From March 2021 to July 2024,Department of Hand Surgery,Suzhou Ruihua Orthopedic Hospital used the flow-through type anterolateral femoral perforators flap pedicled with the oblique branch of lateral circumflex femoral artery to repair wound on the back of the hands of 15 patients caused by hot pressure injury.There were 6 cases of left hand,8 cases of right hand,1 case of both hands,2 cases of back of hand,13 cases of back of hand and fingers.The wound area ranged from 5.0 cm × 4.0 cm to 18.0 cm × 9.0 cm,and the flap area ranged from 6.0 cm × 5.0 cm to 20.0 cm × 10.0 cm.The flap donor sites of all patients were sewn directly.All flaps are repaired 7 to 14 days after the injury.The survival of all flaps was observed postoperatively,and the appearance and feeling of the flaps and the functional recov-ery of the donor and recipient sites were followed up regularly.Results All 15 flaps in this study survived.Postoperative follow-up time ranged from 6 to 13 months,with an average of 8 months.All 15 patients underwent flap thinning 3 to 6 months after surgery,and 4 of them underwent syndactyly division surgery at the same time as flap thinning.At the last follow-up visit,all patients had good flaps,feeling re-stored to S1 to S2,linear scars remained at the donor site of the thigh,and the walking function of the lower limbs was normal.The efficacy of flap repair was evaluated according to the comprehensive flap evaluation scale.The results were rated as excellent in 11 cases,good in 4 cases.The hand function of the patients in this study was evaluated using the trial standard for partial upper limb function evaluation of the Branch of Hand Surgery of the Chinese Medical Association.The results were rated as excellent in 5 cases,good in 7 cases,and fair in 3 cases,with an excellent and excellent rate of 80％.Conclusion The flow-through type anterolateral femoral perforators flap pedicled with the oblique branch of the lateral circumflex femoral artery can reduce the damage to the donor site and avoid damage to the blood sup-ply to the recipient site.This surgical method can achieve satisfactory recovery of hand function and appearance,and is an ideal surgical method for repairing hot pressure injuries on the back of the hand.
