3.When both deep and superficial flexor tendons are involved the fetlock drops when cut behind cannon bone. 4.With complete laceration of tendons and suspensory ligament have complete extension of fetlock, with horse walking on pastern. Can be left open to heal by second intention if excessive contamination has occurred. Suturing - suture only clean wounds and only when apposition is easily acquired with close to normal anatomical positioning. Suture material should be non reactive, and should have long period of strength.
Polypropylene is best since it is strong, non reactive, and accepted for long term healing.
Three Loop Pulley - comparable strength to Compound Locking Loop. Suturing of the tendon provides only opposition of tendon ends. Not strong enough to support full functional weight. Suturing should be used to provide normal anatomical positioning, especially of the paratenon around the tendon ends. Even if the tendon cannot be brought together, the paratendon should be sutured to provide a tube for healing.
