6. Fig. 5
A Kellegren-Lawrence score of 4 was determined for this 69-year-old man 16 years after STT arthrodesis for rotary subluxation of the scaphoid with early SLAC changes. This patient was excluded from statistical analysis of secondary degenerative arthritis because of the preexisting arthritic changes.

7. Fig. 6
The key surgical issue is scaphoid position. Normally the scaphoid lies 47° to the long axis of the radius. In rotary subluxation of the scaphoid it can collapse past 90°. Fusing the STT joint changes wrist mechanics and requires greater than normal flexion of the scaphoid, ideally to 55° to 60°
