The distal check ligament is which of the following?

The distal check ligament is which of the following?

• A. SDF
• B. Interosseous
• C. DDF
• D. Common digital extensor

Answer: (C)

The distal check ligament is tied to the deep digital flexor tendon. In the stay apparatus, this ligament anchors the DDFT as it approaches the coffin joint, limiting how far the tendon can pull the distal phalanx downward when the limb bears weight. This tethering helps keep the limb upright with minimal muscular effort. The other structures listed have different roles: one is mainly associated with the superficial digital flexor tendon, another with the suspensory/aforementioned ligaments in the fetlock region, and the common digital extensor functions elsewhere on the limb. So, the distal check ligament specifically corresponds to the deep digital flexor tendon.
