How do the SDFT and its check ligaments contribute to standing?

• A. They maintain tendon alignment and transmit load during weight bearing, aiding joint stabilization
• B. They cause hyperextension
• C. They are not involved in weight bearing
• D. They primarily rotate the limb

Answer: (A)

The SDFT and its check ligaments act as a passive support system that lets the horse stand by keeping the limb stable and bearing some of the load without constant muscle effort. When weight is on the leg, the superficial digital flexor tendon tightens and the proximal and distal check ligaments anchor it to the bones of the fetlock and pastern. This alignment practice helps transmit load through the tendons and bones, preventing the joints from collapsing and maintaining proper joint position. So the combination mainly stabilizes the limb during weight bearing and supports standing. It doesn’t cause hyperextension, and it’s not about rotating the limb.
