Question 9

Carpometacarpal Joints II-V

Answer 9

• Arhtrokinemtaic motion largely follows osteokinematic motion of distal carpal movement in open kinematic chain.
• Palmar movement of the distal carpals will result in palmar movement of the CMC for II-V.
• Dorsal movement of the distal carpals will result in dorsal movement of the CMC for II-V.
• Radial movement of the distal carpals will result in radial movement of the CMC for II-V.
• Ulnar movement pf the distal carpals will result in ulnar movement of the CMC for II-V.
