Clinical Effect On The Treatment Of Open Wound Of Tendon Of Hand And Foot With Artificial Dermis Combined With Autologous Blade-thick Skin Graft

Objectives To explore the clinical effect of the combination of artificial dermis and splitthickness autologous skin graft for the treatment of exposed hand-foot-tendon wounds,so as to provide more reasonable and effective treatment solutions.Methods A total of 50 patients suffering from exposed hand-foot-tendon wounds in Tangshan Gongren Hospital were enrolled from January 1st,2018 to January 1st,2021 as the research objects.Based on the boundary of October 1st,2019,they were divided into the control group(n=25)and observation group(n=25).After their admission,all patients obtained the routine dressing change for the preparation of the wound.When the wound surface was cleaned and reached the skin grafts conditions,the patients in control group performed the simple autologous skin flap transplantation,while the patients involved in observation group were given artificial dermis to cover the wound in the first stage,and then two weeks later,they accepted the autologous broad-blade skin grafting.Subsequently,the postoperative efficacy of the two groups was compared after the wound was healed.Results After 6 months of follow-ups,the healing time of donor site in observation group was shorter than that in control group,and the healing time of the wounded area was longer than that in control group.In terms of wounded area and donor site,the scores of Vancouver Scar Scale(VSS)were less in observation group both than those in control group.In the two groups,the scores of VSS at 6 months after the wound healing were significantly lower than those at 3.the patients in observation group were more satisfactory to the surgery outcomes than these in control group,and the incidence of malformation was lower in control group(P<0.05).Conclusions It is preliminarily believed that,compared with the autologous skin flap transplantation,the overall treatment effect of artificial dermis with autologous splitthickness skin graft treatment is better for patients developing with exposed hand-foottendon wounds,and the surgery is simpler and easier to be operated,thus indicating the lowest risk.Therefore,it deserves to be promoted clinically.Figure 3;Table 5;Reference 128...
