What are the most common suspensory injuries in horses?
injury to the middle third, or body, of the ligament is easiest to diagnose, but least frequent. National Hunt racehorses and point-to-pointers are most likely to suffer this injury, called body desmitis. damage to the inside or outside branch of the suspensory ligament is also common, particularly in horses which jump, called branch desmitis.
What is a suspensory ligament sprain in horses?
A sprain of the horse suspensory ligament (suspensory desmitis) is usually restricted to one of three areas: injury to the upper third of the ligament (called high, or proximal, suspensory desmitis) is common in horses in all disciplines
What is suspensory body desmitis in horses?
Suspensory body desmitis (injury to the body of the suspensory) is arguably the most common type of injury to the suspensory ligament. Many horses are able to function in spite of the injury during its early stages, often causing the injury to become chronic.
How well will my horse recover from suspensory damage?
How well your horse will recover from suspensory damage depends on which part of the ligament is injured and how bad the damage is, but severe injuries are often career limiting. However, if you’re clued up on signs of potential injury and can target a problem early, the chances of your horse making a good recovery are significantly increased.
How do you treat suspensory injury?
Treatment of a suspensory injury The vet will seek to eliminate any predisposing causes such as poor foot balance or inappropriate shoes; reduce inflammation by the use of cold therapy, laser treatment or therapeutic ultrasound; and to encourage good quality repair of the damaged fibres.
Can a suspensory ligament heal on its own?
Treatment for Strained Suspensory Ligament Ligaments do not have the same propensity to heal naturally as many other parts of the body, and so 're-sewing' the suspensory ligament is often necessary in order to correct the penis injury.
What does a suspensory injury look like?
With a torn suspensory branch, you may see swelling at and above the fetlock on the injured side and the area may be warm to the touch and sensitive to pressure. When the outside branch is torn, lameness may be more obvious when the horse travels with the injured leg on the outside of a circle.

Can a horse fully recover from a suspensory injury?
Ligaments heal slowly. A mild strain may take six to eight weeks, but a tear can take eight to 12 months. High hind suspensory injuries can be especially frustrating because your horse's anatomy makes it hard to follow healing there and harder to know when your horse is ready to return to work.
How do you rehab a horse from suspensory injury?
Rehabilitation Of Tendon And Ligament InjuriesCooling down the inflammation by cold hosing the area is often a first step. ...

What is the usual amount of time required for a horse to heal sufficiently from suspensory ligament Desmitis?
Horses with forelimb injuries are usually able to return to full work 6 –12 mo after surgery depending on the rate of healing. Horses with hind limb prox- imal suspensory injuries can take up to 18 mo before being in full work.
How do you tell if a horse has a tendon injury?
What are the first signs of tendon injury? Damage to a tendon causes inflammation, heat and swelling. Minor fiber damage leads to slight enlargement of the affected part that will feel warmer than the corresponding area on the other limb. Mild strains do not cause lameness.
How much does suspensory ligament surgery cost?
Suspensory ligament release costs between $15,000 and $25,000. While it may release some of the outside penis, the scar tissue formation often causes the penis to retract. Plus it can destabilize the penis, and the ligament can reattach, which puts the patient out thousands of dollars.
How is suspensory ligament injury diagnosed in horses?
Diagnosis of suspensory ligament injuries in horses Ultrasound scans can show a variety of changes to any part of the suspensory ligament. X-rays can be used to check for damage to the adjacent cannon, splint, or sesamoid bones. Occasionally, a bone scan is required to locate the problem.
What happens if the suspensory ligament is damaged?
Tear of the suspensory ligament which is exceedingly rare in clinical practice often results in erectile dysfunction as well as penile instability and changes the angle of erection to a more ventral plane. Physical examination and ultrasound are insensitive methods in the diagnosis of tear of PSL.
What happens if the suspensory ligament is damaged?
Tear of the suspensory ligament which is exceedingly rare in clinical practice often results in erectile dysfunction as well as penile instability and changes the angle of erection to a more ventral plane. Physical examination and ultrasound are insensitive methods in the diagnosis of tear of PSL.
Can you ride a horse with degenerative suspensory ligament?
Riding is not advised for horses with DSLD, due to lameness, instability, and risk of further suspensory breakdown. Degenerative suspensory desmitis occurs in varying degrees and can be managed with shoeing changes, exercise restrictions, and supportive care.
What is the usual amount of time required for a horse to heal sufficiently from suspensory ligament Desmitis?
Horses with forelimb injuries are usually able to return to full work 6 –12 mo after surgery depending on the rate of healing. Horses with hind limb prox- imal suspensory injuries can take up to 18 mo before being in full work.
Can you stretch your suspensory ligament?
The stretchers are not strong enough to stretch the suspensory ligaments that hold the penis under the pubic bone. Therefore the penis behind the ligaments which is about half of the total penis length is not likely to be advanced unless the ligaments are released by my MISL procedure.
What ligament is used to help a horse's fetlock?
The suspensory ligament stretches to let the fetlock sink under the horse’s weight, absorbing shock, and then springs back as he moves off the leg. | © Amy K. Dragoo/aimmedia

How often should I reassess a horse for reinjury?
“I like to reassess with ultrasound every 30 to 60 days, or if the horse shows any sign of reinjury during the rehabilitation,” Dr. Barrett says.
Why is my horse lame?
The horse is lame on the injured leg, but the lameness can be subtle or obvious. It all depends on how badly the ligament is injured. In a severe case, the ligament may sustain a core lesion—a gap in the heart of the ligament—or rupture, leaving the horse lame at the walk. In a mild injury, just a few fibers tear and the horse may be barely off. Ignoring that subtle lameness is dangerous, though. If he keeps working and stressing the ligament, he’s likely to end up with a more severe injury.
What is a torn suspensory ligament?
An unwelcome possibility in both these scenarios is a torn suspensory ligament, an injury that has the potential to limit or end your horse’s career. This ligament has an important role—it supports the horse’s fetlock—and full recovery from a serious tear is never certain.
How to tell if a ligament is damaged?
Bruising, infections and injuries to tendons can produce similar heat and swelling. Your veterinarian can locate the problem with a hands-on exam, flexion tests and local nerve blocks. An ultrasound scan can help pin down the location and reveal the extent of damage to the ligament, and X-rays will show if bone is involved.
What does lots of work in collected gaits stress?
Lots of work in collected gaits stresses the hind limbs and increases the risk of a suspensory injury. | © Amy K. Dragoo/aimmedia
What causes a horse to be lame?
Damage at the proximal part or top of the suspensory ligament invariably causes lameness — varying from mild to severe — which, if the horse rests, can improve rapidly. The lameness tends to be worst when the horse moves in circles with the affected limb on the outside.
How to tell if you have suspensory desmitis?
Signs of suspensory desmitis. A ligament sprain causes heat, swelling and pain. When the middle third, or body, of the suspensory ligament is sprained the signs are easy to detect as there is often obvious swelling that can be seen on both the inside and outside of the injured leg. Heat is easily felt on close examination of the limb.
How does suspensory ligament affect horses?
Suspensory ligament injuries in horses can affect the animal’s future athletic ability. In order to understand why and how injuries occur, it is helpful to be familiar with the structures involved. Ligaments attach bones to each other and act as supports. The suspensory ligament in the horse is a strong, broad, ...
How to treat a proximal suspensory lesions?
Cold therapy and bandaging will usually reduce the swelling, making a definitive diagnosis easier. Once the injured soft tissue structure has been identified, your vet can assess the extent of the damage using an ultrasound scanner, however this is often easier for body or branch lesions than clearly imaging proximal suspensory lesions by ultrasound.
Why do horses have crooked lower limbs?
conformation can play a role – a horse with a crooked lower limb will overload one side of the fetlock and predispose it to a branch injury. poor foot balance is commonly seen in horses which injure the origin of the ligament.
What is the injury to the upper third of the ligament called?
injury to the upper third of the ligament (called high, or proximal, suspensory desmitis) is common in horses in all disciplines. injury to the middle third, or body, of the ligament is easiest to diagnose, but least frequent. National Hunt racehorses and point-to-pointers are most likely to suffer this injury, called body desmitis.
Why does my fetlock swell?
An injury to the inside or outside branch of the ligament will cause swelling on one side of the fetlock. Take care not to confuse this with a swelling due to direct trauma, such as getting cast.
What is a forelimb PSD?
Forelimb PSD is usually characterised by a lameness that’s at its worst when the affected limb is on the outside of a circle on a soft surface. In the early stages, the lameness may improve quickly with rest, but recur when work is resumed. Branch injuries and hindlimb injuries have less consistent patterns of lameness.
Why do horses get lame?
Suspensory injury is a common cause of lameness in all types of horse, however there are certain risk factors…. young, extravagant-moving horses who lack strength and co-ordination may be more at risk of forelimb PSD than older, stronger, better balanced horses. upper level dressage horses are particularly prone to hindlimb PSD.
What is the upper third of the suspensory ligament?
the upper third of the ligament, which is known as proximal suspensory desmopathy (PSD) and may include damage where the ligament attaches to the cannon bone. the body of the ligament, which is the middle third of the suspensory ligament. the branches, which can involve a small lesion that’s contained locally or more widespread tears.
What causes PSD in horses?
These injuries may be the result of a single traumatic event – for example, a horse jumping onto the side of a bank and pulling a front shoe off, resulting in abnormal loading of the suspensory ligament – or due to repetitive overload.
How to tell if a horse has inconsistent ligament thickness?
This can be assessed by facing the side of your horse’s leg, placing your thumbs on the sides of the ligament and running them down his leg – they should remain equidistant. If they get pushed further apart in the lower part of the limb, this usually reflects enlargement of the branch.
What is a branch injury?
the branches, which can involve a small lesion that’s contained locally or more widespread tears. These injuries may also include damage where the ligament attaches to the sesamoid bones
Why is it important to treat soft tissue injury early?
As with any soft tissue injury, recognising the problem early and treating it appropriately is the key to successful management. This is because if injuries go unre cognised, other problems may develop, which can hinder your horse’s chances of recovery – for example, a proportion of horses who’ve had PSD in their hindleg for a while develop pain in the sacroiliac region, which can become a limiting factor for future performance.
How does the suspensory ligament become damaged?
Excessive stress can occur to the ligament when a horse lands after a jump or when it travels at fast speeds. Essentially, an over-stretching injury can occur resulting in damage to the ligament. The damage may be only slight tearing of fibers at the level of their 'origin' (upper cannon bone) or their 'insertion' (sesamoid bones). The damage is usually accumulative over a period of time and may be considered a type of 'repetitive strain injury'. Alternatively a 'core lesion' i.e., 'hole' can be seen (with ultrasound scan examination) in the centre of the body of the ligament or in a branch of the ligament where a number of fibers have ruptured. These injuries usually have a more sudden onset. Complete rupture may occur, in extreme cases, but this is fortunately uncommon.
How can I recognize that my horse has damaged his suspensory ligament?
Clinical signs vary with the site of the injury and the severity of the damage. When the origin of the suspensory ligament is damaged (known as 'proximal suspensory desmitis'), the condition is often 'bilateral' i.e., in both fore or both hindlimbs. There is usually no heat or swelling but there may be some pain when the area just below the back of the carpus ('knee') or hock is pressed firmly with the leg in a flexed position. In these horses the lameness may be subtle and (especially in the hindlimb) often develops gradually and goes undiagnosed for some time. In the forelimbs the lameness may be inconsistent and somewhat variable. When the hindlimbs are affected, the lameness is usually more consistent. The lameness usually becomes worse with exercise, may improve with rest and is usually more obvious when the horse is exercised on a soft surface. In many cases the horse may show signs of poor performance but no overt lameness.
What treatment options are available and can my horse make a full recovery?
Again this depends on the site and severity of the damage and how quickly the condition is diagnosed.
What can be done to follow the repair process?
With body or branch injuries, sequential ultrasound scan examinations are the most useful way to monitor the healing process. In the case of proximal suspensory desmitis, ultrasound changes often lag behind the improving clinical picture and the degree of lameness is often used to assess how well the horse is responding. Depending on the degree of damage, follow-up scans should be performed at one and three months and certainly before any significant increase in exercise level. Any increase in exercise should be made gradually to avoid over stretching the incompletely healed tissues.
Is the injury likely to recur?
Also, the repaired tissue is different in structure and mechanical properties than the original, healthy ligament tissue. Therefore the ligament will always be compromised in structure and function rendering it susceptible to re-injury. However, if the horse is given sufficient time for repair and a careful and sensible approach is made to re-introduction to exercise, re- injury is less likely to occur.
What is the prognosis for proximal suspensory desmitis?
Proximal Suspensory Desmitis - In the forelimbs the prognosis is good. Often a course of 'Extracorporeal Shockwave Therapy' and a period of rehabilitation is all that is necessary. Occasionally this will be done in conjunction with a steroid injection into the region of the origin of the ligament. In the hindlimbs the prognosis for conservative treatment is less good as the anatomy of the hindlimb is slightly different to that in the forelimb which complicates the healing process. Shockwave therapy and medication of the site of injury may be successful depending on the degree and duration of lameness. If this fails a surgical procedure called a 'Plantar Metatarsal Neurectomy and Fasciotomy' can be performed. This is a very common procedure and has a high success rate.
How to repair a suspensory ligament?
Suspensory ligament body and branch injuries: Minor damage to suspensory body and branches will usually repair given sufficient time. This usually means box rest initially with rehabilitation such as cold hosing to reduce inflammation. In acute injuries where a core lesion is present there are substances that can be injected directly into the damaged area of the ligament under ultrasound guidance. These are aimed at improving the structure of the healing tissue and vary in efficacy and popularity. Your veterinarian will advise you if this form of treatment may be appropriate for your horse. In more chronic cases, shockwave therapy is commonly used, followed by a period of controlled exercise, the duration of which depends upon the initial amount of damage. Lameness associated with more severe branch injuries may persist due to the amount of 'fibrosis', or 'scar tissue', that forms around the branch itself. In these cases a surgical procedure called 'suspensory branch splitting' may be required. In cases where a fragment of sesamoid bone has broken away with the damaged ligament (avulsion fracture), the prognosis is poorer.
How to ice a horse's leg?
Cold therapy: There are many ways to ice a horse’s legs, but Ice Horse makes a pair of boots specifically meant for suspensory injuries. The boots cover the leg from the hock to the hoof, and use cooling packets instead of raw ice, which makes less of a mess in the stall or wash rack. Keeping the injured leg and ligament cool, with ice or poultice or another treatment, begins the process of recovery. Coating the leg in cool clay, like poultice is useful, too.
What tests are used to diagnose a suspensory ligament injury?
Flexion tests, nerve blocks, radiography and ultimately ultrasound can be used to diagnose the injury. Treating the suspensory injury begins with time off to let the ligament begin to recover. In difficult cases, surgery may be required to remove blood clots. Veterinarians may prefer different methods of treatment.
Which ligament protects the fetlock from hyperextension?
The suspensory ligament, which attaches at the back and the upper cannon bone in both the fore front and hind limbs, supports and protects the fetlock from hyper-extension. It’s a long ligament, which runs close to the back of the cannon bone before splitting in two, where it connects to one of the sesamoid bones at the back of the fetlock.
What is shockwave therapy for horses?
Other modalities: There are a variety of new therapies on the market that could be useful in rehabilitating a horse with a suspensory injury. Stem cell therapy is one of the most popular options among medical professionals.
Why is my horse weak?
Because there isn’t necessarily “heat” in the leg at the source of a tear or strain in soft tissue, diagnosing a suspensory injury can be difficult. Lameness in the affected limb can be subtle, but will get worse over time if not treated. Generally, the horse will become weaker, especially in that leg.
What do boots cover?
The boots cover the leg from the hock to the hoof, and use cooling packets instead of raw ice, which makes less of a mess in the stall or wash rack. Keeping the injured leg and ligament cool, with ice or poultice or another treatment, begins the process of recovery.
Why do horses over stretch?
Too much stress can cause it to over-stretch, and ultimately damage it. Horses generally injure the suspensory ligament when landing after a jump or while traveling at high speeds. Usually injury occurs over a period of time and strain, and is not necessarily limited to one incident.
What is the function of the suspensory ligament?
The suspensory ligament’s function is crucial to a horse’s movement since it prevents excessive extension of the fetlock joint during the weight bearing or stance phase of the stride.
What happens when the load placed on the suspensory ligament exceeds the collective strength of the entire fiber bundle groups?
Injury to the suspensory ligament occurs when the load placed on it exceeds the collective strength of the entire fiber bundle groups, causing tearing, fraying or rupturing of the individual fibers or fiber bundle groups.
Why do horses gasp when they hear a suspensory injury?
Most people, when they hear their horse has a suspensory injury, have the same gasping response because there’s no quick fix. ”. According to a 1999 study performed by the University of California, Davis, Center for Equine Health, suspensory ligament injuries were the most common injuries or conditions affecting horses, second only to colic.
Why is early diagnosis of suspensory injury important?
As is the case with many injuries, early diagnosis of a suspensory injury is immensely important because the earlier it’s detected, the better chance at confining damage to only heat and inflammation.
Where are the suspensory branches?
The suspensory branches are proximal to the sesamoid bones and the distal sesamoidean ligaments are distal (or below). The distal sesamoidean ligaments lay deep within the soft tissue of the pastern, thus prohibiting easy visualization of inflam-mation or swelling.
Where is the suspensory ligament located?
The suspensory ligament consists of a strong band of fibrous tissue that begins at the top and back of the cannon bone between the splint bones. Approximately two thirds of the way down the cannon bone, the suspensory ligament splits into two branches (medial and lateral), each of which inserts into one
What happens when a horse travels at fast speeds?
Unnecessary stress can occur to the suspensory ligament when a horse travels at fast speeds, lands wrong after a jump or applies too much force to the area. Typically, the damage is cumulative over a period of time and may be considered a repetitive strain injury.
Where is the suspensory ligament located?
The suspensory ligament is a fibrous structure that runs from behind the knee or hock down the limb to insert on the sesamoid bones just above the fetlock joint. It consists of an origin at the top, a body in the middle, and, a little farther down, a bifurcation, where it splits into two structures: a medial (inner) and lateral (outer) suspensory branch. Each branch attaches to the related medial or lateral sesamoid bone. The ligament and its branches form an integral component of the suspensory apparatus, suspending the fetlock during maximum weightbearing when, without these structures, the joint would collapse to the ground.
Can a suspensory branch injury cause lameness?
However, inflammation in the area can cause pain that can result in potentially performance-limiting lameness. In some cases branch injury can also result in effusion (fluid accumulation) and arthritis in the fetlock joint. Even in horses that show no clinical signs of branch injury, veterinarians might detect one following flexion tests or ultrasound during a prepurchase examination, which can result in failure to sell or a reduced selling
Mechanism
Risks
- The suspensory doesnt work alonea team of ligaments and other structures support the legbut its an essential player. And if the horse overloads a leg, it can give way under the stress. Injuries can occur at any point along the ligament:
Pathophysiology
- A high or proximal tear occurs when the fibers that make up the ligament tear at or near its origin at the top of the cannon bone. In some cases a bit of bone tears away with them or a hairline crack may appear in the bone.
Causes
- In a body tear, the ligament tears somewhere between the point where it leaves the cannon bone and the point where it branches. Sometimes the splint bones on either side of the cannon are yanked and irritated or even broken at the tip when this happens. Branch tears can occur in one or both branches. Sometimes a bit of one of the sesamoid bones breaks off in the process. (Sever…
Other animals
- Horses in different disciplines seem prone to different types of suspensory injuries, Dr. Barrett adds. Some studies have indicated that dressage horses are more prone to injuries at the origin of the ligament, while jumpers more often get injuries in the suspensory branches. Researchers at the Animal Health Trust Equine Center in Britain found that dressage horses are more likely to g…
Symptoms
- Trouble Signs The horse is lame on the injured leg, but the lameness can be subtle or obvious. It all depends on how badly the ligament is injured. In a severe case, the ligament may sustain a core lesiona gap in the heart of the ligamentor rupture, leaving the horse lame at the walk. In a mild injury, just a few fibers tear and the horse may be barely off. Ignoring that subtle lameness i…
Diagnosis
- But with so many structures packed into the lower leg around the suspensory, these injuries can be tricky to spot. Even with severe injury, the signs can be confusing. Bruising, infections and injuries to tendons can produce similar heat and swelling. Your veterinarian can locate the problem with a hands-on exam, flexion tests and local nerve blocks. An ultrasound scan can hel…
Treatment
- Ligaments heal slowly and they tend to heal poorly with weak scar tissue in place of the strong stretchy tissue that was damaged. To get the best result, work with the vet to develop a rest and rehabilitation program for your horse. The details of the program will vary with the location and severity of his injury, Dr. Barrett says, but these are the basic elements: Cool down: Heat and sw…
Prevention
- Stall rest: During the cool-down period, which typically lasts two weeks to a month (depending on the injury), your horse should be on complete stall rest. Exercise aggravates suspensory injuries at this pointhealing cant start if the torn fibers are constantly yanked and tugged.
Results
- Rechecks: Repeat ultrasound exams are an essential tool for recovery at every step. Your horse will seem sound long before the ligament is fully healed, and ultrasound scans are the only way to know whats going on inside. As the ligament heals, theyll show that lesions are filling in and that the fibers are increasingly dense and uniform. I like to reassess with ultrasound every 30 to 60 d…
Prognosis
- Injuries at the origin often take longer to heal than body or branch injuries. Dr. Barrett explains. The ligament is surrounded by fascia (bands of fibrous connective tissue) there, creating a sort of compartment. A condition called compartment syndrome can develop, in which swelling within the compartment restricts blood flow. That slows healing, she says. Its also painful.
Function
- PRP is plasma (the straw-colored liquid portion of blood) with high concentrations of platelets, blood cells that release growth factors that spur healing. Bone marrow is also rich in growth factors, and it is one of several kinds of body tissue that contains stem cells (another is fat). Stem cells have the ability to transform into different types of tissue. In suspensory injuries, the hope i…
Cost
- Stem cells may provide a better base for healingthats the hope, anyway, Dr. Barrett says. But, she notes, Regenerative treatments require culturing the horses own cells and ultrasound-guided injection, so they are expensive. Costs vary in different parts of the country, but usually PRP and bone-marrow treatments are equivalent in cost to three shock-wave treatments, and stem-cell tr…
Society and culture
- Desmoplasty, in which the surgeon makes a series of small stab incisions into the ligament. The idea is to stimulate the growth of blood vessels and fibrous tissue in the damaged area, increasing circulation and improving healing. This surgery is done less now than in years past, Dr. Barrett says.
Clinical significance
- Fasciotomy with (or sometimes without) neurectomy of the deep branch of the lateral plantar nerve. In fasciotomy, the surgeon cuts the tough band of tissue that traps the top of the ligament between the two splint bones, relieving compartment syndrome. The neurectomy part of the procedure, which involves cutting the deep branch of the lateral plantar nerve, relieves pain. Thi…
