Overview
X Ray
Hallmark of rheumatoid arthritis are :
- Soft tissue swelling:
- This is an early finding in the course of rheumatoid arthritis.
- Soft tissue swelling is fusiform and periarticular results from of joint effusion, edema, and tenosynovitis.
- Joint space narrowing can be symmetrical or concentric.
- Marginal erosions can result from the erosion by pannus of the bony “bare areas”
Hand and wrist findings
- Common joints involved are:
- PIP and MCP joints (especially 2nd and 3rd MCP)
- Ulnar styloid
- Triquetrum
- Findings seen are:
- Subchondral cysts
- Ulnar deviation of the MCP joints
- Boutonniere and swan neck deformities
- Hitchhiker’s thumb deformity
- Scapholunate dissociation, ulnar translocation
- Ankylosis
Feet
- Various radiological findings are:
- Subtalar joint involvement
- Posterior calcaneal tubercle erosion
- Hammertoe deformity
- Hallux valgus
Shoulder
- Distal clavicle erosions
- Erosions of the superolateral aspect of the head of the humerus
- High riding shoulder due to subacromial-subdeltoid bursitis
Knee
- Joint effusions
- Loss of joint space
- Prepatellar bursitis
Hip
- Concentric loss of joint space
- Acetabular protrusio
Spine
- Atlantoaxial subluxation
- Atlantoaxial impaction: cephalad migration of C2
- Osteoporosis and osteoporotic fractures
- Erosion of spinous processes
