Many foals are born with swollen, floppy tongues. The cause of congenital laxity is unknown. As weight bearing is not always balanced, this can lead to abnormal limb and foot angulation. This article discusses the diagnosis, treatment, and prognosis of these conditions. Bringing a horse back from a tendon injury is a long and sometimes frustrating process. The tendon and the muscle in the area lack strength and cause the foal to use his leg improperly. If the tendon is ruptured, the horse may even walk with the toe tipped up. … Many foals are born with flaccid or weak flexor tendons. Adequate extension force is balanced against splint pressure and rubs. The main functi… Foals that do not respond to this treatment should next be splinted to force extension. "Uterine malposition is the most plausible explanation, and the one most readily accepted by clients," says Dr. Andrew Parks, professor of surgery at the University of Georgia College of Veterinary Medicine. , Horseadvice.com is where equine science and horse sense intersect, since 1997. This is not a deep flexor tendon injury but is too much stretch. Controlled exercise includes stretching the muscle-tendon unit, which can include: Trimming the feet. Flexor Laxity .....Many foals are born with flexor laxity, or looseness of their tendons. This early detection can help avoid a painful rub or blister that will slowly progress. If the foal's leg can be manually forced into normal position, its prognosis is very good. Welcome Guest! Locoweed, Sudan grass and other plants have been reported. Mild defects such as these can be managed, and most can result in a productive horse. Pathologic bone problems leading to abnormal tendon development is believed likely as well as the existence of various defects in elastin and collagen production. Tendon laxity refers to a disorder that causes weak flexor tendons. The hind feet of these foals are usually affected, though the front feet can be involved as well. There is restricted space in the uterus, and some foals become twisted or "stuck" in awkward positions that do not allow them to stretch their limbs and move about. Churro had significant tendon laxity around his carpi which allowed his joints to hyperextend backwards and collapse in towards one another – a posture known as valgus. Parks, "it is the explanation that is probably the most difficult to support from a research standpoint." Flexor tendons are long strips of fibrous tissue enclosed in a tendon sheath that run down the back of each leg. In the hind limbs, the flexors also straighten the hock. These abnormally positioned legs develop tightened or shortened ligaments and tendons. A complete lameness examination should be performed because many horses that are back-sore are protecting some other area causing lameness, such as the hocks. But how you manage your horse's injury can make all the difference in the outcome. This is normal and results in odd leg angles and stances. New research may help identify more causes for laxity and contracture in foals, but that information is still on the horizon. Symptoms may include: Unable to stand Attempting to walk on upper part of fetlocks Able to stand but knuckle in the fetlock joint or carpi Sores on the feet Rapid identification of foals with problems and aggressive treatment is still the best method of straightening out these crooked foals. Numerous case reports in the literature describe tendon contracture in foals born to mares that were exposed to various plants and toxins. The typical foal is bright and alert, but when it stands it places the palmar (plantar) surface of the hoof on the ground and the toe does not bear weight. Still have questions? Though this foal had some difficulty initially, it stood and nursed unassisted. Constant observation of these splints is necessary and, since foals grow quickly and angles should change as improvement occurs, they must be continually adjusted. It was treated medically with intravenous oxytetracycline and splints were applied to the front legs. His interests include muscle problems in sport horses, rehabilitation and other performance issues. She really looked like a mess at birth, had trouble standing and a lot of issue walking. The causes of these deformities include tendon laxity (loose tendons and weak supporting muscles), underdeveloped bones in the joint, or uneven growth of the bones of the limb. These foals will stand knuckled over to varying degrees. The foal was managed conservatively with simple exercise, and the condition resolved within one week. Those that do not resolve in this time period, should not be overlooked. Toxins, unusual plants, chemicals and possible pasture, hay or water contaminants should be investigated. Various infectious agents have been implicated, but much more research needs to be done before a definitive link can be made to any particular disease. Expired members can use this link to renew their membership, just choose a plan, sign in, and checkout. Tendon contracture and laxity problems in foals common, but still serious Uterine malposition. This foal, born with tendon contracture, has the typical "windswept" appearance with curvature of the back, hips, stifles and hocks. An online horse care and equine health encyclopedia. This laxity is again believed to be caused by trauma at the time of birth. The majority of these foals self-correct in a few days. Uterine malposition, teratogenic insults (arthrogryposis), and genetic defects have been either implicated or proved to cause contracted limbs in newborn foals. "However," adds Dr. This condition usually fixes itself with controlled exercise. Loose joints may also be the result of cleidocranial dysostosis, an inherited disorder affecting bone development. In this article, I'll walk you through the steps to recovery and tell you when and how you can help. Carpal (inferior) check ligament desmotomies and flexor tenotomies have been successfully used to correct these foals. A tendon sheath is a fibrous membrane that envelops the tendon itself. If you lift your horse's leg and manipulate his hoof while palpating the pastern with your other hand, you should be able to feel the play of the extensor branches of the suspensory ligament angling forward over the sides of the pastern … At this point in time, no treatment has been shown to be more effective or quicker than controlled rest and rehabilitation in giving a horse with an injured tendon or ligament a chance to return to full function. Tendon laxity In premature and neonatal foals, tendons and ligaments may be too relaxed instead of too contracted. Contracture occurs most commonly at the carpas or fetlock. This piece is cut to extend forward and below the level of the foal's hoof. You must be logged in to create new topics. Do you need a equine reference you could use at home, at the barn, even on the trail. Thermography or infrared camera use has been proven to be very beneficial in locating very early areas of pressure. Care must be taken to ensure that toe bruising or abscessation does not occur. Because this produces tendon or ligament laxity, it may correct angular limb deformities in young foals. The extension will force stretch the ligaments and tendons and can help resolve many cases of contracture. Until then, it is important to control those factors that have already been identified and to aggressively treat these twisted foals when they occur. "Well-managed programs seem to do an excellent job of controlling diet and environmental factors," Parks says. Tendon laxity can be present in all four limbs. "Correctly applied splints are the next best step and are usually very helpful in most cases," Stashak says. No special tests are necessary. Within 10 days, the foal had responded well, and the front legs were almost normal. In the horse, the two digital flexor tendons run down the back of each leg, with the deep digital flexor tendon lying beneath the outer or superficial tendon. The length of the extension can be reduced, as the foal's angles become more and more normal. The Tendon Support Boot is intended to be worn during exercise only and it enables horses recovering from tendon or ligament injury to be exercised safely during rehabilitation giving the maximum chance of full recovery. Affected limbs must be palpated carefully to detect ligament laxity and specific areas that may be painful. Articles and discussions on Tendon Laxity and Contracture written and moderated by an equine veterinarian. © 2021 MJH Life Sciences™ and DVM 360. These twisted foals are in fact referred to as "windswept" and, though most grow out of the condition, their early management can be complicated by their problems. Though most commonly seen in the fetlock and the pastern, it can occur in the carpus (knee), and it is more common in the rear limbs. This treatment may include firmer splinting of the entire lower limb and sometimes oxytetracycline is used as this can relax the tendons, this may be contra-indicated though given the laxity of the other limb. A striking feature of the condition is the flexor tendon laxity that leads to hyperextension of the fetlock joints. Dr. Ted Stashak, professor of surgery at Colorado State University College of Veterinary Medicine, advises that the only way to differentiate this rare condition from the more commonly seen laxity is to monitor improvement in each foal. Genetics may be more of a factor than was previously thought, and there is hope that new advances in gene mapping will shed some light on the exact reasons for the development of contracture and laxity. In severe cases these foals may precipitate dystocias. Uterine malposition is the most common reason given for these congenital contractures and laxities. These two tendons work together to flex the knee and all the joints below the knee when the horse moves. The time for concern is when the abnormalities are so bad that they prevent the foal from standing and getting around well or when the malformations do not correct rapidly. Contracted tendons are the most potentially serious problem while excessively loose or lax ligaments are probably more commonly seen. These conditions usually involve the ligaments and tendons of the lower limbs, but potentially any such structures in the body can be affected. The distal radial metaphysis, physis, epiphysis, or cuboidal bones may be the site of deviation. Horses with long pasterns and flat hooves are more likely to get tendonitis, as this conformation tends to overstretch the tendons. Maintaining these horses in support wraps over long periods, however, might lead to flexor tendon laxity (looseness) and increased risk of injury. Exercise is important and is often directly correlated to tightening of these affected tendons and a return to normal alignment of the fetlock and the bearing surface of the hoof. Heavy paper mailing tubes can be used on very small foals, but Stashak favors PVC pipe that is sized, cut and heat-bent to the appropriate angle. Usually, it is most obvious in the hind limbs with the fetlock dropping close to the ground, and occasionally the toe will lift off the ground when the foal is bearing weight on that leg. It is easy to become complacent because the vast majority of cases, even initially severe ones, usually improve in a few days. Helping Thousands of Equestrians, Farriers, and Veterinarians Every Day since 1997. Flexor tendon laxity can affect one or more limbs but usually occurs in the hind limbs (Figure 183-5). Tendinitis is a common debilitating injury seen in all types of performance horses. Horseadvice.com Better information makes for healthier horses for less cost! Weak flexor tendon in horses is also known as flaccidity or dropped fetlocks. Your assurance of excellent customer service. Extreme care must be taken to be sure that these foals receive adequate colostrum and nutrition in the first few days of life or until their condition improves. Tendon contracture and laxity in foals is not an uncommon problem and one that most equine practitioners routinely deal with just about every foaling season. Clients need to know that contractures and laxities are potentially serious problems and veterinarians should treat these conditions with the urgency they deserve. Occasionally foals are born with such a collection of contractures through their legs and upper bodies that they literally resemble rubber Gumby horses hit by a stiff wind. The presence of glucocorticoids has known adverse effects on tendon fibroblasts, such as suppression of tenocyte activity and disturbance to proteoglycan production. Filly was born with severe tendon laxity on his front fetlocks, as well as hyperextension in her knees. The affected horses exhibit hyperextension of the fetlock joints of all limbs with varying severity. There always seems to be at least one foal that is born with one of its parts too tight, too loose or somehow out of place.
