Radiocarpal and Midcarpal Joints Movement

• flexion and extension have same amount of rom (85 degrees) and opposite joint ROMs:

  • flexion = RC 50 degrees, MC 35 degrees
  • extension = RC 35 degrees, MC 50 degrees
  • think about it logically as theres 2 palmar ligaments at RC joint, so less extension available
  • limiting factors are opposites as well
