2) Uniform joint space narrowing (cf Osteoarthritis)
3) subluxation (ulnar common)
Osteoarthritis:-
DIP, First carpometacarpal, weight bearing (spine, hips, knee)
1)Asymmetric narrowing of joint space
2) Subchondral sclerosis
3) Osteophytes and spurs
4) Degenerative cysts
Tuberculous:-
commonly affects thoracis/lumbar spine(Pott's)- can cause both osteomyelitis and arthritis, erosions(destruction) of the adjacent vertebrae, causing collapse, kyphotic angulation and occasionaly cord compression.
Can affect knee/other joints.
history, ZN stain of the exudate, microscopy of the synovium for granuloma, giant cells, PPD test, etc to support the diagnosis.
