Tension saw construction

In horse anatomy, a tension saw construction is the sinewy transformation of two skeletal muscles of the lower leg : the fibularis tertius muscle and the flexor digitorum superficialis muscle . The sinewy peroneus tertius muscle spans the front of the rear extremity from above the knee joint to the metatarsus, while the flexor digitorum superficialis muscle spans the rear side from above the knee joint to the heel hump ( calcaneus ). This construction of two clamping devices around a central axis (lower leg bone) is similar to the clamping saw .

With this arrangement, the direction of movement of the knee and ankle joint is synchronized, that is, a flexion of the knee joint results as long as both tendon cords are intact, always also in a flexion of the ankle joint.
