Internal fixation of scaphoid fractures.

Scaphoid fracture fixation is indicated in certain acute situations and for scaphoid nonunion. Internal fixation requires an understanding of the distinctive scaphoid anatomy with relation to its shape, blood supply, fracture healing, and radiographic evaluation. The choice of surgical approach varies with the fracture configuration and procedure planned. A variety of innovative implants are available to accomplish internal fixation of the scaphoid. The ultimate goal is to achieve union and restore stability to the carpus.
