DDF check ligaments are weaker in the pelvic limb and sometimes absent.

DDF check ligaments are weaker in the pelvic limb and sometimes absent.

• A. True
• B. False
• C. Not known
• D. Always present

Answer: (A)

In the stay apparatus, ligaments that connect the deep digital flexor tendon to the surrounding bones help limit excessive flexion during weight bearing. In the pelvic (hind) limb, these DDF check ligaments are not as consistently robust as in other limbs; they can be weaker and are sometimes absent. This variation reflects how the hind limb achieves stability primarily through other structures and mechanisms, such as the reciprocal action between the stifle and hock and the surrounding ligaments and tendons, rather than relying as heavily on a strong DDF check ligament. So the statement is correct: DDF check ligaments are weaker in the pelvic limb and may be absent in some individuals.
