Distraction Osteogenesis Technique for the Management of a Gustillo Type I Tibial Shaft Fracture Initially Managed with an Intramedullary Nail Device.

Abstract

Fractures of the tibia shaft are the most common long bone fractures, especially in young male adults. Due to specific anatomical features, these fractures are more common than any other long-bone fracture. This is one of the main reasons they are associated with twice the incidences of deep infection compared with any other bone and can be combined with the presence of segmental bone defect. Many reconstruction techniques have been used to manage such cases, including Ilizarov technique, Masquelet technique, vascularized fibula transfer, and the monolateral external fixator. We present a case of a 21-year-old male patient who was admitted to our hospital for a Gustillo type I tibial shaft fracture which was initially treated by an intramedullary nail device. Two months postsurgery the patient presented with clinical signs of infection in the area of the fracture site, confirmed by an osteolytic lesion revealed radiographically. A surgical operation was performed that included a tibial osteotomy proximal to the defected bone, bone excision, and application of a LRS external fixation device. Antibiotic therapy was administrated based grown cultures, and regular follow-up X-ray revaluation was performed. After six months, the bone was radiologically united, the frame was removed, and the leg was protected in a walking boot while the patient used only partial weight bearing. The treatment of segmental bone defects associated with infection and soft tissue loss presents a great challenge, and the choice of the appropriate method requires further study.
