What is another term for the suspensory ligament of the navicular bone?

• A. Lateral collateral ligaments of the navicular
• B. Supraspinous ligaments of the navicular
• C. Medial collateral ligaments of the navicular
• D. Deep digital flexor tendon sheath

Answer: (A)

The suspensory ligament of the navicular bone is another term for the navicular collateral ligaments, specifically the lateral one. These ligaments run at the sides of the navicular bone to stabilize it within the coffin joint, helping suspend and support the navicular from the surrounding structures. The other options don’t describe this hoof structure: the supraspinous ligaments are parts of the spine, the medial collateral ligament is the opposite side but not the commonly used term for the suspensory structure of the navicular, and the deep digital flexor tendon sheath is a synovial covering around the tendon, not a ligament of the navicular bone.
