What role do the ligaments of the wrist joint play in wrist motion?
What will be an ideal response?
ANS:
The ligaments check intercarpal motion and are partially responsible for the sequence of movement during wrist motions. That is, the ligaments result in the bones of the distal carpal row acting as a unit; the ligaments are also responsible for close-packing the scaphoid to the distal carpal row at neutral position (as the wrist extends from full flexion) and for close-packing all the carpal together at 45 ° of hyperextension (as the wrist extends from the fully flexed position).
