ClinConnect Summary

The scaphoid is the most commonly fractured carpal bone accounting for 60% of fractures. A number of case series have identified a 10%-15% nonunion rate. Scaphoid nonunion refers to a spectrum of failed healing, each of which requires a tailored approach.

Subsequent to non-union, degenerative changes with the formation of cysts, bony resorption with loss of bone stock and the development of apex dorsal angulation or the humpback deformity may occur leading to scaphoid non-union advanced collapse (SNAC) of the wrist and the formation of a proximal pole which extends with the lunate.
