股前外侧穿支皮瓣与胸腹带蒂皮瓣对手外伤组织缺损修复的应用效果及对创面愈合程度的影响.

Objective: To explore the effect of anterolateral thigh perforator flap and thoracoabdominal pedicled flap on the repair of hand traumatic tissue defect and the effect on wound healing. Methods: A total of 119 patients with hand trauma tissue defects admitted in our hospital from December 2018 to December 2020 were selected as the research objects, and they were randomly divided into 2 groups. They were the control group (n=59, using thoracic-abdominal pedicle flap repair) and the observation group (n=60, using anterolateral thigh perforator flap repair). The excellent and good rates of the two groups were compared. The hand wound area, wound healing degree and tissue healing time before and after treatment were compared between the two groups. The scores of Jamar grip strength, TAM and dash were compared between the two groups. The flap survival rate, flap crisis rate and vascular anastomosis time of the two groups were compared. Results: By comparing the excellent and good rate of the two groups, it was found that the number of excellent patients in the observation group was 21 cases, the number of good patients was 35 cases, the excellent and good rate was 93.33%, the number of excellent patients in the control group was 16 cases, the number of good patients was 30 cases, the excellent and good rate was 77.97%, the observation group was higher than the control group (P<0.05); After treatment, compared with the control group, the hand wound area, tissue healing time and DASH score of the observation group were significantly reduced, and the degree of wound healing and TAM and Jamar grip strength were significantly increased(P<0.05). By comparing the flap survival rate, postoperative flap crisis rate and vascular anastomosis time of the two groups, it was found that there was no significant difference in the flap crisis rate and vascular anastomosis time of the two groups (P>0.05), but the flap survival rate of the two groups was significantly different, and the observation group was significantly higher than the control group (P< 0.05). Conclusion: The application of anterolateral thigh perforator flap and thoracoabdominal pedicled skin flap in the repair of hand trauma tissue defect has obvious repair effect, but the application of anterolateral thigh perforator flap can improve the treatment effect, improve the wound healing degree, reduce the healing time, improve the hand movement of patients, and improve the survival rate of postoperative flap, which is worthy of clinical application and promotion.
