Non-union is incomplete consolidation of a fracture, without effective formation of a uniting callus. Despite better understanding of the physiology of bone consolidation, management of tibial non-union remains a challenge for orthopedic surgeons. Several treatments have been developed in recent decades, and we now have a range of techniques, with indications based on type of non-union, prior treatments, available equipment, and the surgeon's experience. Firstly, there are surgical techniques such as osteo-periosteal decortication, cancellous iliac graft, or inter-tibiofibular graft. The decision to fix the non-union (or revise existing fixation) and choice of type of internal fixation depend on the stability of the fracture site. There are also non-operative biological and biochemical consolidation stimulation techniques: local injection of bone-marrow, platelet-rich plasma (PRP) or bone morphogenetic protein (BMP). Stimulation can also be physical, applying ultrasound or an electromagnetic field to the non-union site. Each technique may be used in isolation or association.Le texte complet de cet article est disponible en PDF.
