Functional splinting of upper limb injuries with gauze-based topical negative pressure wound therapy

Complex hand injuries can be difficult to dress effectively and achieve adequate splintage of the hand in a functional position. During the past 7 years, we have had a great deal of success with topical negative-pressure dressings in the management of complex blast-related extremity war injuries. We have more recently changed to using a gauze-based system and have found this particularly useful in dressing complex hand injuries. We have been able to use this vacuum dressing system to splint the hand in a position of function. This provides an easily applied dressing that, through topical negative pressure, promotes wound healing and ensures a resting functional position, thus minimizing postoperative stiffness. We have not been able to achieve this as efficiently with standard dressings and plaster-of-Paris casts. This article details the technique of functional splinting of complex hand injuries using a gauze-based, topical negative-pressure dressing system.
