Pathological Changes in Osteoarthritis

Pathological Changes in Osteoarthritis

1. Remodeling of bone contour


2. Fibrillation and focal loss of hyaline cartilage


3. Marginal Osteophytes (ossification of new fibro-cartilage)


4. Subchondral sclerosis


5. Cysts


6. Secondary Bursitis


7. Capsular Thickening


8. Osteochondral Body


9. Synovial Hyperplasia


10. Secondary enthesopathy

What is enthesopathy?

In medicine, an enthesopathy refers to a disorder involving the attachment of a tendon or ligament to a bone. This site of attachment is known as the entheses.

If the condition is known to be inflammatory, it can more precisely be called an enthesitis.

Features of Osteoarthritis (FCPS July 2010)

1. Deformity of joints


2. Coarse crepitus due to rough articular surface


3. Bouchard’s nodes at distal interphalangeal joints


4. Heberden’s nodes at proximal interphalangeal joints


5. Structural changes are permanent

Ans: T T F F T

Bouchard’s node

Bouchard’s nodes are hard, bony outgrowths or gelatinous cysts on the proximal interphalangeal joints (the middle joints of fingers or toes.)

Heberden’s node

Heberden’s nodes are hard or bony swellings that can develop in the distal interphalangeal joints (DIP) (the joints closest to the end of the fingers and toes).
