The suspensory ligament relieves stress from which ligaments?

The suspensory ligament mainly functions to support the fetlock and carry part of the weight that would otherwise press on the flexor tendons. Running along the palmar/plantar aspect from the cannon bone to the proximal sesamoid bones, it acts like a spring and prevents excessive extension of the fetlock during weight-bearing. By taking on this load, it reduces the stress on the digital flexor tendons—the superficial and deep digital flexor tendons—helping them bear less of the load themselves. The other structures mentioned have stabilizing or guiding roles (collateral ligaments provide side-to-side stability; annular ligaments organize tendons around the joint; dorsal ligaments have different support functions) and aren’t the ones relieved by the suspensory ligament.
