The hallmark of<unk>  arthritis is soft tissue swelling, joint space narrowing, and erosions. Hand and wrist findings on xray include subchondral cysts, ulnar deviation of the MCP joints, boutonniere and swan neck deformities, hitchhiker’s thumb deformity, scapholunate dissociation, ulnar translocation, and ankylosis. Feet findings on xray are subtalar joint involvement, posterior calcaneal tubercle erosion, hammer-toe deformity, and hallux valgus. Findings of shoulder such as distal clavicle erosions, erosions of the superolateral aspect of the head of the humerus, and high riding shoulder due to subacromial-subdeltoid bursitis. Knee findings include  joint effusions, loss of joint space, and prepatellar bursitis. Hip findings include concentric loss of joint space and acetabular protrusio. Spine findings are atlantoaxial subluxation, atlantoaxial impaction: cephalad migration of C2, osteoporosis, and osteoporotic fractures, and erosion of spinous processes.
