The treatment of Gustilo type IIIB and IIIC open fractures remains a challenging problem, because the infection rate is 15-45%. Infection can lead to serious complications such as osteomyelitis or amputation. The intra-wound continuous negative pressure and irrigation treatment (IW-CONPIT) was developed for infected wounds and intractable ulcers, and is very effective in suppressing infection and accelerating wound healing. Here the IW-CONPIT was applied to severe open fractures for the purpose of preventing infection. After thorough debridement and lavage of the wound, bony stabilization is performed by external fixation. Dermal matrix is grafted onto any areas where the bone or tendon is exposed. A sponge containing two tubes is placed over the entire surface of the wound including the dermal matrix. Then it is covered with a film dressing to make the wound completely airtight. A bottle of physiologic saline solution is attached to one tube, and a continuous aspirator is attached to the other. This system maintains negative pressure on the wound surface, which is continuously irrigated. Thirty-five patients were treated with this method. A superficial infection developed in two cases but was resolved by additional debridement and continued application of IW-CONPIT. Complete wound healing was obtained with split thickness skin graft in all cases. There were no complications such as osteomyelitis, delayed bone union or amputation. IW-CONPIT was able to definitively prevent wound infection in Gustilo type ⅢB open fractures. We believe this method will become a standard treatment option for this condition.
