How does the suspensory relieve stress from the DDFT/SDFT?

• A. Absorbs concussion and gives impulsion
• B. By lengthening the limb
• C. By reducing blood flow to the area
• D. By increasing joint temperature

Answer: (A)

The suspensory apparatus acts like a spring in the leg. When the horse lands, the suspensory ligament stretches and absorbs the concussion from impact, storing elastic energy. As it recoils, it helps push the leg forward, providing impulsion. This spring-like action takes a portion of the load that would otherwise be carried by the deep and superficial digital flexor tendons, helping to protect them from excessive stress.

So, the primary effect is absorbing concussion and aiding propulsion. It doesn’t lengthen the limb, alter blood flow, or raise joint temperature, which aren’t functions of the suspensory mechanism.
