  1. 1. MRI of the wrist joint. DR/ ABD ALLAH NAZEER. MD.
  2. 2. Indications for MRI of the wrist joint. 1. Acute and chronic wrist instability. 2. Dorsal or ulnar-sided wrist pain. 3. Wrist symptoms in adolescent gymnasts and other athletes. 4. Unexplained chronic wrist pain. 5. Acute wrist trauma. 6. Avascular necrosis. 7. Wrist malalignments. 8. Limited or painful range of motion. 9. Unexplained wrist swelling, mass, or atrophy. 10. Planning for diagnostic or therapeutic arthroscopy. 11. Recurrent, residual, or new symptoms following wrist surgery.
  3. 3. Subchondral erosion of lunate
  4. 4. Scaphoid waist fracture with subtle collapse of the proximal pole, related AVN .
  5. 5. Kienböck's Disease.
  6. 6. Kienböck's Disease.
  7. 7. Capitate avascular necrosis.
  8. 8. DISI deformity
  9. 9. DISI deformity.
  10. 10. Scapho - lunate ligament tear
  11. 11. Scapholunate and lunotriquetral ligament tear
  12. 12. 1. Scapholunate ligament tear, dorsal angulation of the lunate and proximal migration of the capitate consistent with a DISI deformity. 2. Tear of the lunotriquetral and triscaphe ligaments.
  13. 13. Triangular fibrocartilage complex tear.
  14. 14. Ulnar variance may be : neutral (both the ulnar and radial articular surfaces at the same level) positive (ulna projects more distally) negative (ulna projects more proximally) Causes trauma or mechanical distal radius/ulnar fractures with shortening (e.g. impaction) & angulation DRUJ ligamentous injuries (e.g. Galeazzi & Essex-Lopresti) surgical shortening of ulna or radius growth arrest (e.g. previous Salter-Harris fracture) congenital Madelung deformity/reverse Madelung deformity Associations positive ulnar variance is associated with ulnar impaction syndrome. negative ulnar variance is associated with Kienbock disease and ulnar impingement syndrome
  15. 15. Positive ulnar variance secondary to TFC tear.
  16. 16. Negative ulnar variance secondary to TFC tear.
  17. 17. Swelling , deformity , abnormal signal of the median nerve
  18. 18. Lipoma of the carpal tunnel.
  19. 19. Carpal tunnel syndrome caused by cysticercosis
  20. 20. Ganglion cyst.
  21. 21. Tenosynovitis Tenosynovitis is an inflammation of the tendon, either primary or secondary. Marked inflammatory tenosynovitis.
  22. 22. Tenosynvitis of abductor pollicis longus (APL) and extensor pollicis longus (EPL).
  23. 23. Tenosynovitis of the flexor tendons.
  24. 24. Tenosynovitis of all flexor tendons FDS, FDP, FPL
  25. 25. Tenosynovitis with partial tears of the EPL, ECRB and ECRL
