Keinbock's: Cystic changes in the lunate indicate potentially keinbock's disease, which occurs most commonly when the ulna is slightly shorter than the radius. Sometimes immobilization helps, but a distal radius decompression surgery can revascularize the lunate and prevent collapse.

Depends: The tfcc (triangular fibrocartilage complex) is a complicated structure that supports the wrist on the ulnar (pinky) side. A possible explanation for the findings you describe would be one of several ulnar-sided impaction syndromes where there is excessive load bearing across that side of the wrist. The changes you describe are typical. See a hand specialist to determine if treatment is needed.
