Timing of debridement: When to do it, and who should perform it?

The timely and effective management of open fractures continues to be a challenge in modern orthopaedic practice. Lower limb high energy fractures with complex soft tissue injuries require multi-disciplinary care to achieve the best results. Despite an extensive published literature on open fractures, the timing of debridement and the most appropriate personnel to perform it continue to be a source of debate. National guidelines on the topic are few but they suggest immediate debridement for open fractures with highly contaminated wounds and debridement within 12 to 24 h is considered desirable for less contaminated wounds. There is actually limited evidence linking timing of debridement to infection risk but the largest studies recently published do indicate a link between delay to debridement and increasing infection risk. Most studies on management are based on a clinical model where the initial debridement and fixation are performed by an orthopaedic surgeon and if required delayed coverage and closure is subsequently carried out by a plastic surgeon. More recently, studies have proposed an alternative approach, with initial debridement and temporary fixation followed within 48 h with a further debridement, definitive fixation and flap cover with a combined orthoplastic team. Reported results have been favourable. This is a significant change in management and there are limited data at present to determine if this approach will improve results in the most complex open fractures.
