Abstract:
Objective To investigate the clinical efficacy of membrane induction technique(Masquelet)combined with free ultrathin anterolateral thigh perforator flap(ALTP)in reconstructing foot and ankle wounds.Methods This is a prospective study.Sixty-three patients with foot and ankle wounds complicated with bone defects admitted to Hefei Second People's Hospital from January 2022 to June 2023 were selected and randomly divided into control group(n=32)and study group(n=31).Control group was treated with traditional bone grafting combined with ultrathin ALTP,while study group was treated with Masquelet technique combined with ultrathin ALTP.Clinical data of both groups were collected,and flap efficacy,bone healing,ankle joint function,and daily living ability were compared at 6 and 12 months after surgery.The incidence of complications was compared between the two groups after 12 months of postoperative follow-up.Results There were no statistically significant differences in clinical data such as age,gender,cause of injury,injury site,and wound area between the two groups(P>0.05).By the end of follow-up,the median follow-up time was 17(12-28)months,and the follow-up rate at 12 months after surgery was 100.0%.There was no statistically significant difference in flap survival rate between study group and control group[100.0%(31/31)vs.87.5%(28/32),P=0.129].There were no statistically significant differences in the excellent and good rates of wound healing,flap sensation,flap morphology,flap temperature,donor site scar at 6 months after surgery,as well as wound healing,flap temperature,donor site scar,and bone healing at 12 months after surgery between the two groups(P>0.05).The excellent and good rates of bone healing at 6 months after surgery,the excellent and good rates of flap sensation and flap morphology at 12 months after surgery,and the scores of American Orthopaedic Foot and Ankle Society(AOFAS)and Activities of Daily Living(ADL)scale at 6 and 12 months after surgery in study group were significantly higher than those in control group(P<0.05).The incidence of complications in study group at 12 months after surgery was significantly lower than that in control group(P<0.05).Conclusion Masquelet technique combined with ultrathin ALTP in reconstructing foot and ankle wounds is beneficial to flap survival,bone healing,and recovery of ankle joint function,which can improve patient's daily living ability and reduce the incidence of postoperative complications.
