Purpose
Aim of this study was to compare the use of split-thickness skin graft (STSG) with and without additional MatriDerm® application in a predominantly one-step procedure for the treatment of severe traumatic soft tissue defects of the lower limb.
Methods
This retrospective study included patients treated in a European level I trauma center between June 2013 and July 2018 in terms of a severe traumatic soft tissue defect of the lower extremity using STSG alone or in combination with the acellular dermal substitute MatriDerm®. The healing of the soft tissue defect was measured by assessment of the take rate. Outcome quality of the scar tissue was assessed using the Vancouver Scar Scale.
Results
A total of 147 cases were included in this study. The overall healing rate (number of patients with take rate ≥ 75%) was 88/147 (60%) and did not demonstrate significant differences between the treatment groups (p = 0.15). Despite the difference in wound complexity between the treatment groups, there was no difference regarding the scar tissue quality 12 months postoperatively. In about 25% of all cases, a post-operative event was mentioned that had to be revised surgically.
Conclusion
Surgical treatment with STSG and additional MatriDerm® application can be recommended as satisfactory alternative for dermis replacement in patients with severe skin defects, independent of age. The additional MatriDerm® use allows for bridging of exposed ligaments, tendons, vessels or bones without relevant differences in cosmetical outcome.
