RADIOCARPAL JOINT
|
articulation b/w radius and proximal carpals; biaxial, condyloid joint filled with synovial fluid (AKA wrist joint)
|
|
LIGAMENTS THAT SUPPORT THE RADIOCARPAL JOINT
|
medial (ulnar collateral ligament), lateral (radial) collateral ligament
|
|
MEDIAL COLLATERAL LIGAMENT (WRIST)
|
connects the ulnar styloid to the triquetrum and hamate; limits radial deviation
|
|
LATERAL COLLATERAL LIGAMENT (WRIST)
|
connects the radial styloid to the scaphoid and trapezium; limits ulnar deviation
|
|
MIDCARPAL JOINTS
|
articulation b/w the proximal and distal row of carpals; non-axial, plane joints gliding movements of the carpals bones
|
|
LIGAMENTS THAT SUPPORT THE MIDCARPAL JOINT
|
dorsal intercarpal ligament, palmar intercarpal ligament
|
|
DORSAL INTERCARPAL LIGAMENT
|
connects radius to the proximal carpals posteriorly; stabilizes carpals during wrist flexion
|
|
PALMAR INTERCARPAL LIGAMENT
|
connects radius to proximal carpals anteriorly; stabilizes carpals during wrist extension
|
|
CARPOMETACARPAL (CMC) JOINT
|
articulation b/w the distal row of carpals and the metacarpals; biaxial, modified saddle
|
|
