surgery for scaphoid nonunion with humpback deformity

Scaphoid nonunion may result in a so-called "hump back" deformity when the scaphoif flexes at the nonunion, and carpal collapse develops. If union is the only yardstick by which outcome is assessed, your scaphoid may heal--but you may not regain adequate wrist extension and you may be at risk down the road for arthritis.

Accordingly, I will carefully assess your xray when you visit the office. If you have a DISI deformity (extended lunate bone), and a scaphoid nonunion, you may require a structural bone graft and screw--so that the scaphoid deformity is corrected. Indeed, long-term outcome is going to be most ideal if your scaphoid heals without a persistent hump back deformity. This will be critical to restoring wrist extension, which is generally lost when a hump back deformity is present because of the associated carpal collapse.
