The challenges of managing Gustilo IIIB tibial fractures (ie, high energy trauma with a contaminated wound >10 cm in length, severe comminution ["crumbling"] or segmental fractures, and periosteal stripping) in children are unique in part because no clear guidelines exist and the injuries may cause short-term and long-term complications. Repeated wound debridement and secondary reconstruction are required in approximately 20% of these cases in both adults and children. A 13-year-old girl presented with severe polytrauma including an open Gustilo type IIIB fracture of the left lower leg. The patient declined limb amputation; a multidisciplinary team (plastic, pediatric, orthopedic-trauma surgeons, pediatrician, psychiatrist, clinical pharmacologist, anesthesiologist, physiotherapist, nurses) was assembled in order to give the patient the best chance of a successful outcome. Multiple limb salvage and reconstructive procedures including wound debridements, necrectomies, long-term negative pressure wound therapy, soft tissue reconstructions, external bone fixation, bone osteosynthesis, multiple skin grafts, and free-flap reconstruction were provided over a period of 6 months with great success. The patient is doing well 3 years after initial injury and is walking without complications. A multidisciplinary approach and structured treatment plan are important to minimize complications, avoid unnecessary delays in treatment, decrease morbidity, and provide the patient with the best result possible. Studies examining optimal treatment strategies for children and adolescents with these complicated fractures are needed.
