| Intraosseous ganglia when associated with osteoarthrosis may be difficult to divorce from large subchondral cysts. |
| Subchondral cysts were noted to involve the bilateral capitates, the left hamate, and the right scaphoid. |
| Joint destruction occurs with erosion of juxtaarticular bone around the margins of pannus and invasion of subchondral tissue by pannus. |
| An anterior capsulotomy was then performed, followed by decortication of the subchondral bone neighboring the torn labrum. |
| Theories include vascular insufficiency or micro-fractures of the subchondral plate, with synovial fluid being forced from the synovial space into the bone. |
| It is characterized with joint cartilage degeneration, subchondral bone changes, and synovitis. |
