Screw Fixation Alone for Scaphoid Fracture Nonunion.

Scaphoid fracture nonunion can often lead to pain, arthrosis, and disability. While typically the result of delayed diagnosis or inadequate treatment, it can sometimes occur even if the initial care was timely and appropriate. Whereas early recognition of acute fractures allows for nonoperative management, nonunions frequently require surgical treatment. Traditionally, this has involved open debridement and bone grafting. However, some publications suggest that certain stable nonunions may be amenable to percutaneous debridement and fixation without formal bone grafting. Although certain characteristics appear to be appropriate indications for such management, well-designed clinical studies are needed to better define them.
