  21. Acceptable for scaphoid? • Why or why not 21

  22. 22

  23. Positioning error? 23

  24. The separation of the proximal radius and ulna indicates that the elbow was rotated from a true AP projection 24

  25. The humerus and forearm are not in the same parallel plane to the IR (epi’s) • and the elbow is extended beyond 90°. • (?) 25

  31. 31 Bennett's fracture • is caused by forced abduction of the thumb • there is a dislocation of the base of the first metacarpal although a fragment continues to articulate with the trapezium.                                          <>

  32. 32 Rheumatoid Osteo Arthritis

  33. 33 RHEUMATOID ARTHRITIS

  34. Rheumatoid arthritis RA - inflammatory disease 3x more common in females

  35. Osteoarthritis of fingers. Note narrowing of interphalangeal joints with spurring and erosions OA - Non inflammatory joint disease involves the articular cartilage – Aging /erosion

  36. 36

  37. 37 Transradial styloid perilunate fracture-dislocation

  38. Fracture of the trapezium (greater multangular) 38

  40. Torus /buckle fx 40

  41. Impacted fracture with bulging of the periosteum. Torus or Buckle 41

  42. Which carpel bone is the most common for fracture? 42

  44. Extension-Compression Fracture of Distal Radius Colles’ Fracture FX WITH POSTERIOR DISPLACEMENT 44

  49. Colle's fractures usually occur when an adult falls on a hyperextended, outstretched hand. There is frequently an associated fracture of the ulnar styloid. Secondary degenerative arthritis may develop at the wrist joint. Same as Colles except there is volar displacement and angulation of the distal fragment
