The use of dermal regeneration template (Pelnac®) in a complex upper limb trauma: the first Italian case report.

Dermal regeneration template (DRT) has been well widely implicated in the reconstruction of full-thickness injury. We present our experience and our clinical application of Pelnac® to achieve wound closure with complex acute, upper limb, full-thickness defect post-trauma. A 22-year-old boy presented a soft tissues loss of the back of the hand and forearm with tendon's involvement and exposure. The wound was treated with Pelnac®; the silicone layer was removed at postoperative day 30 and dermal regeneration template was reapplied at the level of the residual tendon exposure; a split-thickness skin graft (0.2 to 0.3 mm) was inserted. Clinically, the reconstructed areas demonstrated good granulation tissue at 14 days with a good take of the skin graft. There were no major acute graft loss, rejection or associated infections cells through downregulating TLR4 expression.
