Question

a joint is most stable in which position?

a) close-packed position

b) equally stable in an open-packed and maximal loose-packed position

c) open-packed position

d) maximal loose-packed position

Explanation:

In joint biomechanics, the close - packed position of a joint is when the joint surfaces are maximally congruent, which provides the greatest stability. Open - packed and maximal loose - packed positions have less congruency and thus less stability. So a joint is most stable in the close - packed position.

Answer:

a) Close - Packed position
