Answer

When only a single joint is affected, radiography is important to exclude other diseases. Basic radiographic changes in JIA include the following:

  • Soft tissue swelling

  • Osteopenia or osteoporosis

  • Joint-space narrowing

  • Bony erosions

  • Intra-articular bony ankylosis

  • Periosteitis

  • Growth disturbances

  • Epiphyseal compression fracture

  • Joint subluxation

  • Synovial cysts
