Describe the articulations of the transverse tarsal joint
What will be an ideal response?
ANS:
The transverse tarsal joint (TT) is a composite S-shaped joint that lies transversely across the foot. It is formed by the talonavicular joint medially and the calcaneocuboid joint laterally. The talonavicular joint is a fairly mobile plane joint that has already been described as part of the TCN. The calcaneocuboid is also a plane synovial joint, formed by two reciprocally convex-concave facets on the calcaneus and the cuboid. This facet shape requires that the moving segment move in opposite directions intra-articularly, limiting the motion that can take place.
