AbstractScaphoid fracture is the most common carpal fracture. Nonunion rate has been reported around 10 to 15% of scaphoid fractures. Risk factors for scaphoid nonunion are known as location, displacement, poor vascularity, time to treatment etc. The goals of surgical treatment for scaphoid nonunion are to achieve bony union, to correct carpal deformities and also to prevent progressive carpal instability and arthritis. Scaphoid nonunion can cause scaphoid nonunion advanced collapse (SNAC) which is a pattern of progressive degenerative radiocarpal and midcarpal arthritis secondary to posttraumatic pathomechanics of the scapholunate joint. Achieving bony union is essential to prevent carpal collapse or arthritis. To improve bony union, many surgical procedures including various forms of bone grafting have been developed and attempted. However, there is a controversy about which procedure is the most effective. In this review, we provide an overview of surgical treatment methods for scaphoid nonunion and discuss proper surgical strategies for scaphoid nonunion which requires surgical management.
