AbstractRelease and autografting remains a mainstay of treatment of cutaneous and joint-associated contractures. However, owing to secondary contraction of grafts and the increase of children undergoing burn reconstructive surgery, recurrence of contractures is not uncommon. Locally available, well-vascularised tissue that will contract minimally and grow with the patient is the ideal for contracture release. Many 'predesigned' cutaneous flaps have been described, but use of these may involve tailoring a defect to fit a known flap. We introduce the concept of the 'ad hoc' perforator flap, an improvised island flap based on a perforator, innominate or otherwise, that happens to be adjacent to a particular soft-tissue defect and can be reliably raised on scarred skin. We carried out a retrospective analysis of all patients undergoing contracture release within our unit. Twenty-three ad-hoc perforator flaps in 20 patients were carried out between 2000 and 2005. Eleven of the 20 patients were children, and all but one case was subsequent to a burn injury. Fifteen of the 23 flaps were upper limb. In one case, a significant complication involving total flap loss occurred. Only one patient required a skin graft to close the flap donor site, and no patients required revisional surgery for contracture recurrence. The ad hoc perforator flap is a safe and simple technique for the management of contractures, and fulfils the ideal of well-vascularised tissue that can grow with the patient. The flap can be designed as required and, with experience, the concept is applicable not only to contracture release, but many other reconstructive scenarios.
