New proposal for skin grafts on tendon-exposed wounds

Abstract

Performing a skin graft is not feasible for tendon-exposed defect reconstruction because tendons are fibrous connective tissues with relatively poor blood supply. This study proposes a method to effectively perform skin graft surgery in tendon-exposed wounds. A 48-year-old male patient with diabetes mellitus had a very large left dorsal foot defect (8×8 cm). The wound bed had healthy granular tissue, with tendon exposure. The tendons were turned over so that the posterior side would behave as the anterior side. The edge of the paratenon was then fixed together to the surrounding granulation tissue or dense remnant fascia using ab-sorbable sutures, and the close granulation tissue was approximated and buried. A split-thickness skin graft was performed after 1 week. The graft site was stably taken on postoper-ative day 3. A small disruption was then observed at the graft site within 1 week postopera-tively, but conservative treatment was continued for 1 month, after which the defect site was completely restored. This technique can increase the success rate of skin grafts for defects with tendon exposure.
