Equine Swollen Leg
Tendons and ligaments play critical roles in the musculoskeletal system. Feed them well and treat them kindly.
Tendons and ligaments are specialized forms of connective tissue. Tendons connect muscle to bone. Ligaments are anchored on the bone at both ends. Both are composed of interwoven strands of type I collagen protein in a structure much like a rope. They are built to resist stretch, but both structures do stretch.
Tendons facilitate movement by pulling on bones when a muscle contracts. Stretching that occurs (e.g. when the fetlock drops during weight bearing) has an effect similar to pulling on a rubber band. When the stretch is released, the tendon snaps back to its original length, and this assists the pull of the muscle.
Ligaments are meant to restrict movement. They are able to dissipate their stress because they contain strands of elastin, a protein which can deform then resume its original shape.
Overstretching can damage any tendon or ligament. Fatigue and working in deep footing are further risk factors, as are toe grabs or overly long toes and shoes with bars or heel extensions that delay breakover. Age and PPID (Cushing's disease) also weaken these structures.
On the nutritional end, adequate protein in general is needed for connective tissue health and maintenance. The essential amino acid lysine is especially important because strengthening linkages in collagen and cross-links in elastin occur where lysine is located in their structure.
A good broad-based supplement that provides the following nutrients, many of which are commonly deficient, is an inexpensive and common-sense way to support the health of tendon and ligament tissue.
- Vitamin C and copper are two nutrients critical to maintaining the integrity and strength of these tissues.
- Magnesium deficiency has been found to cause a dramatic reduction in the protein content of tendons.
- Collagen from animals with vitamin E deficiency is deficient in strengthening cross-linkages.
- Zinc deficiency slows the rate of collagen production.
Research has discovered that nitric oxide is critical to processes that maintain the normal integrity of tendons and ligaments under and after stress. This is particularly important for athletic horses. The herb Jiaogulan is potent support for the generation of nitric oxide in pathways that help promote homeostasis and healthy tissue.
Tendons and ligaments also benefit from good old-fashioned hands-on care. Exercise is normally accompanied by a degree of inflammation. This is how tissues receive the signal to strengthen their structures and antioxidant defenses. The process is temporary but sometimes causes discomfort, heat and edema.
Simply massaging the tissue or water therapy with pressure is soothing because it facilitates blood delivery to the tissues. Adding a liniment with the right ingredients can boost the benefits:
- Aloe Vera, Chamomile, Arnica, and Comfrey are proven to contribute to the homeostatic balancing of inflammatory reactions
- Lavender essential oil gently supports circulation
Uckele Health & Nutrition, maker of CocoSoya®, offers supplements that support healthy connective tissue.
Jiaogulan supports circulation in the feet, which nourishes the tissue. Jiaogulan strongly supports the activity of endothelial Nitric Oxide Synthase. This enzyme resides in the lining of blood vessels. It synthesizes Nitric Oxide, a simple gas that is a potent dilating agent that promotes a healthy inflammatory response.
Vitamin C promotes the body’s innate resistance to pathogens and protects against damaging free radicals to maintain a healthy inflammatory response. Horses in need of tendon and ligament support may also benefit from Vitamin C supplementation since it is important to the formation of collagen, the major protein in those tissues.
Cool Muscle Liniment soothes and cools muscles and supports normal, healthy blood flow, but is gentle the coat and skin. With an all-natural 100% Aloe Vera juice base and hand tinctured herbs. Lavender Essential Oil gently encourages normal blood flow, and Comfrey Leaf supports a balanced inflammatory reaction. Organic Rosemary Extract provides antioxidant action and normal muscle relaxation
