Advanced degenerative changes as cartilage thinning and loss associated with subchondral edema and cystic changes are seen at radiocarpal and ulnocarpal as well as proximal row of the wrist bones.
Marginal osteophyte formation also is seen at the distal part of the radius and ulna bones.
TFCC tearing is associated with the fluid signal at the distal radioulnar joint.
The fluid signal also is seen around the flexor carpi radialis tendon related to tenosynovitis.
Although osteoarthritis of the wrist is routinely diagnosed using plain film, a thorough assessment of TFCC, tendons, and cartilage injuries using MR imaging or MR arthrogram remains necessary before any surgical procedure.
