Use of tissue expanders for wound closure of spinal infections or dehiscence.

Posterior spinal incisions that are made through skin and have been compromised by radiation or prior incisions can be difficult to obtain stable closure. In addition, if a wound has developed a postoperative infection or wound dehiscence caused by poor wound healing, severe complications can develop. The technique of expanding adjacent normal skin with implantable tissue expanders has been used in select cases with success. The techniques and indications for tissue expansion in posterior lumbar wounds is reviewed and several case reports presented.
