===Distal Interphalangeal (Coffin) Joint===

===Distal Interphalangeal (Coffin) Joint===

The coffin joint, between the distal trochlea of the middle phalanx, distal phalanx and the distal sesamoid ('''navicular bone'''), allows extension and slight flexion movements. The '''navicular bursa''' lies between the navicular bone and the deep digital flexor tendon. The joint capsule attaches to the articular periphery and has two pouches, a small dorsal and larger palmar pouch.  The dorsal pouch extends under the common digital extensor tendon to just proximal of the coronary band. The palmar pouch extends under the deep digital flexor tendon to the approximately half way up the middle phalanx. It dips between the distal phalanx and sesamoid and bulges laterally where it is related to the collateral ligaments.

It dips between the [[Phalanges - Horse Anatomy#Distal Phalanx|distal phalanx]]  and sesamoid and bulges laterally where it is related to the collateral ligaments.  

The '''collateral ligaments''' connect the distal part of the middle phalanx to the medial and lateral sides of the proximal distal phalanx. The '''distal sesamoid ligaments''' connect the distal border of the navicular bone to the flexor surface of the distal phalanx. The '''collateral sesamoid ligaments''' are fibroelastic ligaments that attach to the proximal phalanx with the collateral ligaments of the pastern joint and insert to the proximal border of the navicular bone. The ungual/lateral cartilages have a series of ligaments going to the medial/lateral surfaces of the three phalanges and distal sesamoid. There is also a fibrous band connecting the inner surfaces of the cartilages by crossing the superficial aspect of the deep digital flexor tendon.
