UE joints, lig, bursa

Question 0

radiocarpal joint

Answer 0

• proximal=radius & articular disk
• distally = scaphoid, lunate, triquetrum
• articular disc = TFCC (triangular fibrocartilage complex)

Question 1

distal radioulnar joint

Answer 1

• proximal = ulnar notch of radius & head of ulna
• distal = articular disc
• capsule & synovial memb
• ligaments
• sacciform recess: proximal extension of capsule between distal radius/ulna

Question 2

palmar ligaments of wrist & distal radioulnar joints

Answer 2

1. ulnar collateral lig (ulna–>pisiform)
2. ulnocarpal ligament (ulnolunate & ulnotriquetrial lig)
3. radial collateral lig (radius to trapezium)
4. radiocarpal lig (radiocapitate & radiolunate lig)

Question 3

dorsal ligaments of wrist and distal radioulnar jt

Answer 3

1. dorsal radiocarpal lig (radial styloid–>prox row of carpals)
2. ulnar collateral lig
3. radial collateral lig

Question 4

intercarpal joints and ligaments

Answer 4

Interosseous (intercarpal) ligaments

• connecting proximal row carpals
• connecting distal row carpals

palmar intercarpal ligaments
-palmar radiate ligament

Dorsal intercarpal ligaments

Question 5

wrist joint injuries

Answer 5

radiocarpal

• colles fracture of distal radius
• strain of palmar radiocarpal lig (radiocapitate, radiolunate)
• fracture of scaphoid
• dislocation of lunate
  - pushed toward palmar side of wrist
