BACKGROUND: Wounds that heal slowly may pass through a subacute phase and proceed to reach a chronic situation. The latter may heal slowly, if at all. These wounds often heal by secondary intention with a single layer of epithelium that has a tendency to break down. Methods that expedite healing by full-thickness skin usually involve operative procedures. A nonoperative method of achieving coverage of tardy wounds with full-thickness skin, partial or complete depending on the wound, would be valuable.
PATIENTS AND METHODS: A device has been designed that approximates the wound margins by applying constant low-grade tension over a period of days or weeks. One or more devices have been applied to the wounds of 25 patients to date.
RESULTS: Healing has been obtained in those patients (20) where the devices were used optimally. In 5 patients, optimal use was not possible, mostly for socioeconomic reasons; the latter included noncompliance, insurance problems, economic difficulties, and personal considerations. In these 5 cases, healing was obtained in the 3 that were available for follow-up, full-thickness skin coverage being estimated by grid photography to be in the 80% to 90% range. One patient was lost to follow-up after the wound was 95% covered by full-thickness skin. One patient whose wound reduced in size declined further treatment after 12 days of treatment.
CONCLUSIONS: It appears that when constant-tension, low-grade force is applied to subacute and chronic wounds, healing is accelerated and, depending on the wound, a considerable number of ulcers can be closed by full-thickness skin.
