The extensor branch of the suspensory ligament connects with which tendon?

The extensor branch of the suspensory ligament connects with which tendon?

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

Answer: (D)

The extensor branch of the suspensory ligament threads into the extensor mechanism to help stabilize the fetlock during weight-bearing. It splits from the interosseous ligament near the fetlock and runs distally to blend with the common digital extensor tendon. This connection allows the suspensory ligament to influence the extensor system, aiding extension of the fetlock as part of the stay apparatus. The other tendons listed are flexors (like the superficial and deep digital flexors) or have separate roles, so they don’t receive this extensor-branch connection from the suspensory ligament.
