In scaphoid fractures, delayed diagnosis and nonunion are fairly common as a result of several factors, including the difficulty of radiographic diagnosis of non-displaced fractures and underestimation of the injury by the patient. Main factors to consider when deciding treatment are the type of fracture and fracture stability. In the stable nonunion (Type D1 according to the Filan and Herbert classification, or linear type of Ikeda's classification), percutaneous screw fixation without bone graft is recommended. The indications of non-vascularized bone grafting are as follows: (1) arthroscopic cancellous bone graft in type D1 and cystic type of Ikeda's classification. (2) tricortical bone graft from the iliac crest in type D2 or D3 if the possibility of avascular necrosis of the proximal fragment is excluded. In this paper, our non-vascularized bone grafting for scaphoid nonunion would like to be described mainly about principles and type of fixation. DOI: 10.1007/s00590-016-1868-6
