Abstract: Objective To explore the efficacy of microvascular technology combined with perforator flap repair in the treatment of soft tissue defects in hand injuries.Method 98 patients with hand injury soft tissue defects admitted to our hospital from August 2018 to February 2023 were selected as the study subjects.The patients were randomly divided into a control group and an observation group using a random number table method,with 49 cases in each group.The control group was treated with thoracoabdominal pedicle flap repair,while the observation group was treated with microvascular technology combined with perforator flap repair.Compare the efficacy,visual analogue scale (VAS) score,histopathological score,total finger mobility (TAM) score,sensory function grading,and comprehensive quality of life assessment questionnaire 74 (GQOLI-74) score between two groups before and after treatment.Result After 6 months of surgery,the therapeutic effect of the observation group was significantly higher than that of the control group (95.92% vs 79.59%)(P<0.05).On postoperative days 3 and 7,the VAS score of the observation group was significantly lower than that of the control group,while the histopathological score was significantly higher than that of the control group (P<0.05).After 6 months of surgery,the TAM score and sensory function grading in the observation group were (3.37±0.43) and (4.17±0.12) levels,respectively,higher than those in the control group (2.27±0.26) and (3.32±0.12) levels (P<0.05).After 6 months of surgery,the psychological,physical,social,and material function scores of the observation group were significantly higher than those of the control group (P<0.05).Conclusion The combination of microvascular technology and perforator flap repair has a significant therapeutic effect on patients with hand injury tissue injury,which can improve their hand sensation and motor function,alleviate pain,and improve tissue healing and quality of life.
