Is Surgery Recommended For Kissing Spine In Horses If They Are Just To Be Paddock Animals
Kissing spine can cause severe hurting and seriously touch a horse's performance. Discover out what the signs are and how information technology can be treated...
A horse with kissing spine is idea to feel consequent, low-grade pain from its back considering the spinous processes (the sections of os that indicate up from the primary vertebrae that behave the spinal column) printing confronting or rub on each other during movement. The veterinary description of kissing spine is impingment (when the bones are touching) or overriding (when the bones overlap) dorsal spinous processes (IDSP/ODSP).
The bones with the barbed processes run from the beginning thoracic vertebra (T1) at the horse'southward withers to the last lumbar vertebra (L6) at the point of the hip, with the T13 to T18 basic being the nigh commonly affected. This is the expanse where the saddle and the rider are located.
Information technology is important to be enlightened that although changes on X-rays can exist readily identified, they are typically insufficient to brand a diagnosis. Many horses with changes on 10-ray practise not show any discomfort. This is certainly a challenging condition with more to information technology that might at first appear.

Typical signs of kissing spine
The signs of kissing spine can be subtle and are non-specific, but may include:
- The horse showing signs of discomfort (such equally shifting weight, pulling faces, biting) when being clean-cut over the back or when pressure level is applied to the back such as when the saddle is put on or girthed up
- Changes to the horse's normal temperament and demeanour when working or existence prepared to work
- The equus caballus may go hard to mount, refusing to stand up however, running backwards or forwards when the passenger'southward weight is added
- When being worked the horse may evidence signs of stiffness through the back. Information technology may be unwilling/unable to work 'on the bit' preferring a hollow or constantly changing outline or repeatedly tossing its head.
- The horse may struggle to make transitions between the paces or within a pace, dropping behind the passenger'south leg and testify a reluctance to go forwards with impulsion
- The horse may buck, rear, run away, kick out, or repeatedly shy
- Canter is often a key indicator of kissing spine with many horses struggling to pick upwards the correct lead or maintain a truthful three-beat out canter, tending to pause or go disunited instead
- A horse with kissing spine is likely to show a loss of muscle mass across its topline
- Horses may besides be reluctant to curlicue or lie downwards
Many of the typical signs can too be caused by a behavioural or training issue, or a medical status that is not related to the horse's dorsum, so keeping a note of any changes yous notice so you tin share this detailed history with a vet is cardinal so they can course part of the discussion prior to diagnosis.
It is noteworthy that some horses alive with signs of kissing spine shown on X-rays without showing signs of discomfort and savor a successful working life without requiring whatever veterinary intervention.
If your equus caballus is showing a combination of the signs above, we would recommend working with your vet and your trainer together to identify the source of the result every bit soon as possible. Further investigations are important rather than relying on vague signs or X-rays solitary.
Diagnosing kissing spine
A vet called to a suspected kissing spine case will want to hear the horse's history and will take into consideration its age, breed and gender. They volition typically undertake a consummate physical examination of the equus caballus, including easily-on palpation of the entire trunk – not just the equus caballus's back.
This volition exist followed by a lameness examination, with the equus caballus trotted-upwards in hand, potentially lunged and then worked under saddle, if this tin be done safely, so they can compare the horse'south movement and fashion of going with and without a load on its dorsum.
Some vets will inject a local anaesthetic between the spinal processes that they believe to exist troublesome — basically a nerve block — before repeating the lameness work-up. Ultimately thorough clinical imaging is the all-time way to confirm if the spinal processes are impinging on each other. As well as the often all too obvious X-ray changes, nuclear scintigraphy (bone scans), thermography, and ultrasound are also options that can provide helpful information.
"Kissing spine often has very subtle symptoms," says Dr Svend Kold, a specialist in equine orthopaedic surgery. "We watch the equus caballus being schooled and expect at everything, including the horse's demeanour, limbs, posture, whether he is accepting the bit, whether he unlocked in his back, and the expression on his face. The trot is often okay, simply the horse invariably struggles to maintain a three-trounce canter and frequently gets disunited."
What types of horses are affected?
Information technology is predominantly racehorses and competition horses who are referred for treatment. This could be because it is more noticeable in operation horses due to the physical demands on them, while in horses only used for hacking and low-level work, the trouble may go unnoticed. Alternatively, it may exist that functioning horses are more decumbent to the condition, due to the physical demands placed on them. There is also a belief the condition may be hereditary.
Veterinary literature has suggested that up to 34% of horses (which tend to exist over-represented by thoroughbreds) may evidence signs of kissing spine on X-rays, simply many do not showroom any clinical signs equally a event of them and may not accept any illness. It is always important to dominion out other causes for business organization, such equally a poorly fitting saddle, passenger issues or indeed lack of fitness.
Treatment for kissing spine
In cases where a definitive diagnosis has been made that the kissing spine are the true site of pain with the equus caballus showing obvious signs of discomfort, surgery can be used to rectify the problem. However, the original functioning adult has been modified in contempo years to offer a far less invasive, and much cheaper choice, with a far shorter recovery period.
"Instead of removing sections of bone, the ligaments betwixt the spinal processes are cutting — an Interspinous Ligament Desmotomy (ISLD)," explains Ricky Farr, MRCVS. "This can exist done under continuing sedation.
"Some of the ligaments betwixt the spinous processes in the back are cut through a very small incision (unremarkably less than 1-two cm) in the pare. This technique has gained popularity among surgeons due to being minimally-invasive and horses are frequently back into piece of work inside six to eight weeks."
The ISLD is typically best suited to cases were the spinous processes are shut and believed to be touching at times when the horse is in movement, rather than cases where the bones are significantly overlapping. In these cases, removal of bone may exist required.
The original operation, which was adult in the 1980s, saw pregnant chunks of bone removed from the spine under full general anaesthetic with recovery times of iii months or more. The adventure of complications from this blazon of surgery is also much higher.
In some cases an ISLD under standing sedation is now combined with a 'bone shave' process, where some smaller sections of bone are removed via an incision along the top of the dorsum, but which does not require a general anaesthetic.
Dr Kold explains the traditional surgery procedure: "After the incision along the dorsum, we would cut through the supraspinous ligament. Once all muscular and ligamentous attachments are severed down either side, we cut off effectually half the spinal processes, removing about three inches of bone. Next, the ligaments and skin are sutured. Afterward the procedure, a void is left, as the bone doesn't re-abound and a blood jell forms, followed by fibrous tissue."
A small United states studyi (xviii horses), published in 2020, found horses which showed improvement when having their back 'blocked' with local anaesthetic during diagnosis were more likely to experience a long-term improvement in clinical signs later on undergoing ISLD surgery than those who did not tested prior to surgery.
Non-surgical treatment options
Whether or non to operate depends on how badly the basic are pressing on each other, the individual horse's tolerance levels, his lifestyle and the owner's fiscal state of affairs.
Some horses with confirmed kissing spine tin can be successfully managed with a regular, such as twice-yearly steroid injection into the area betwixt the spinal processes. This will need to be combined with ongoing suitable physiotherapy and grooming to strengthen and maintain the horse'south core muscles and the muscles over the horses dorsum to help back up the spinal cavalcade. A rehab programme of physiotherapy and grooming to strengthen the back and core muscles volition also be required after surgery.
Equine surgeon Bruce Bladon says: "In cases where nosotros're talking about the normal flexibility of the spine occasionally resulting in the edges of the basic 'kissing', information technology is piece of cake to run into how increased muscle tone every bit a issue of physiotherapy and a change in work, might foreclose this."
Other methods that your vet may recommend to help control the pain and inflammation associated with kissing spines include:
- shock wave therapy
- therapeutic ultrasound
- non-steroidal anti-inflammatory drugs (NSAIDs)
- muscle relaxants
- chiropractic
- acupuncture
Prognosis
About horses diagnosed with kissing spine are able to render to ridden work after appropriate veterinary treatment and a recommended rehab programme is completed. In some cases they may be unable to render to the same level of work as before, simply are comfortable when working at a lower level. Research from a 2019 study2 of 71 cases dating from 2012 to 2017 undertaken in the US found 91.1% of horses successfully returned to work subsequently ISLD surgery, with 52.9% returning to the same or a higher level of performance than before surgery.
Paddock retirement is an option for most horses if the owner is unwilling or unable to undertake the advisable veterinary treatment and rehabilitation that the equus caballus requires, just some volition cope well with an adjusted riding regime, so never requite up too quickly. Very few horses with kissing spine require euthanasia, unless they have other underlying issues that cause ongoing hurting.
It is worth noting that some horses with kissing spine will also accept limb lameness that may be directly or indirectly associated with their back hurting. In some cases this lameness just becomes clear once the kissing spine has been resolved. Information technology is possible that the back pain is secondary to the lameness, so ever best to consider the bigger picture.
