*The '''carpometacarpal joint''' between the distal carpal bones and the proximal metacarpals

The joint is a synovial joint, comprised of a common outer fibrous capsule and three inner synovial pouches, one for each joint. Numerous ligaments add to the stability of the joint and ensure movement is largely limited to the [[Planes and Axes - Anatomy & Physiology|sagittal plane]], although no collateral ligaments exist in the dog between the radius and the proximal metacarpals. This allows a very small amount of rotation.

*'''Collateral ligaments''' extend from the radius to the metacarpal bones on the medial and lateral aspect of the carpus.

*The carpal canal houses both the deep digital flexor tendon and the deep branch of the superficial digital flexor.

 

The metacarpal joint is defined by the presence of palmar [[Bones and Cartilage - Anatomy & Physiology#Types of Bone|'''sesamoids''']], which allow the flexor tendons to pass over the sharp change in angle presented by the joint. These are paired on each digit, with the exception of the first digit where it exists.
