Broke scaphoid. diagnosed 8mth later. failed bone graft. avascular necrosis. do not want fusion. apart frm arthritis is there anything to worry about?

Scaphoid fracture : Post traumatic avascular necrosis of scaphoid if untreated will lead to collapse of scaphoid with resultant distorted anatomy ( architecture of carpal bones ) . This will lead to degeneration and progression of degenerative arthritis in the wrist with pain and restricted mobility.

Wrist instability: Any time your normal anatomy is altered there is a risk of instability of the joint, increase laxity of ligaments.
