====Distal Interphalangeal Joint====

* Movement - extension, slight flexion.  

The distal interphalangeal joint allows extension and slight flexion movements. The joint capsule attaches to the articular periphery of the bones and has a small fibrocartilagenous bead in the palmar aspect. The '''collateral ligaments''' connect the distal part of the middle phalanx to the sides of the ungual crest of the distal phalanx. The '''dorsal ligament''' connects the proximal dorsal border of the extensor process of the distal phalanx. These are paired in dogs and function is to keep the claw raised until contraction of the deep digital flexor acts to overcome their tension.
