Wound coverage using modified tissue expansion.

We describe the use of a "lacing apparatus" across large and complex wounds to accomplish wound closure. This technique utilizes the principles of tissue expansion (exploiting inherent extensibility of the skin, mechanical creep, and biologic creep) but is able to employ them in situations in which traditional tissue expansion (utilizing implantable expanders) is not practical. After preparation, the wounds are laced with large nylon suture, which is tightened on a daily basis, typically allowing closure of even massive wounds within 8 to 10 days. In this report, we describe the technical details of wound preparation, application of the lacing apparatus, and postoperative execution of the expansion leading to final wound closure. This technique is particularly valuable in the upper arm, trunk, and lower extremity but has limited application in the distal forearm and the distal third of the lower extremity.
