Scaphoid fractures and scaphoid nonunion. Diagnosis and treatment.

Abstract

Scaphoid nonunion can cause pain, loss of wrist motion, and loss of grip strength. Because initial roentgenograms are not always definitive, patients suspected of having a scaphoid fracture despite negative initial radiographs should undergo bone scan. Treatment of acute nondisplaced fracture of the scaphoid generally nonoperative, involving immobilization in a cast. Treatment of scaphoid nonunion is generally operative, and many procedures and their associated risks are reviewed. There is no consensus about the clinical implications of scaphoid malunion.
