Abstract:
Objective:To study the clinical value of artificial dermis combined with autologous thin skin graft in the repair of burn scar contracture in joints.Methods:A total of 52 patients with burn scar contractures were enrolled in the No.5 Hospital of Baoding from July 2015 to April 2018. According to different methods of repair, 26 cases were used in each group. The observation group was treated with artificial dermis combined with autologous thin skin graft. The control group was treated with medium-thickness skin grafting. The survival rate of autologous skin was compared between the two groups. The tissue of artificial dermal polyester fiber was taken and HE staining was performed to observe the pathological changes. The Vancouver skin scar assessment score (VSS), functional activity, infection rate, wound healing time, and VSS score after healing of the donor site were compared between the two groups.Results:The survival rate of autologous skin in the observation group (92.31%) was not significantly different from that in the control group (84.62%) ( P>0.05). Compared with preoperative, the VSS scores at 3, 6 months and 1 year after operation in both groups were decreased ( P<0.05). The VSS scores of the observation group were lower than those of the control group at 3, 6 months and 1 year ( P<0.05). The excellent rate of functional activity in the observation group (100.00%) was higher than that of the control group (76.92%) ( P<0.05); There was no significant difference in the infection rate (3.85% vs 7.69%) and healing time of skin grafting area between the two groups ( P>0.05). The healing time of donor site was shorter than that of the control group ( P<0.05). The VSS score of the donor site was lower than that of the control group ( P<0.05). Conclusions:Artificial dermis combined with autologous thin skin graft can be used in patients with burn scar contracture in joints, which can improve the scarring of skin grafting area and donor site, shorten the healing time of donor site and improve the function of burn scar contracture joint.
