Increased sclerosis of the proximal pole of the scaphoid with evidence of a waist fracture in keeping with non union and AVN of the proximal pole. There is also widening of the scapholunate interval. Joint space narrowing, osteophytosis and mild subchondral sclerosis of the radioscaphoid articulation in keeping with osteoarthritis.

Impacted fracture of the scaphoid waist. Widening of the scapholunate interval.

Case Discussion

Degeneration of the radioscaphoid articulation is the first stage of a SLAC and SNAC wrist. In this case, the cause is SLAC as the widening that the capitate will migrate proximally through is the scapholunate interval rather than the un-united scaphoid fracture.
