What does the interspinous ligament do?

What does the interspinous ligament do?

Function. The role of the interspinous ligament is to limit flexion (bending forwards) through restricting separation of the spinous processes of the vertebral column.

What is interspinous ligament Desmotomy?

Interspinous ligament desmotomy allows affected horses to return to some level of performance, regardless of the severity of radiographic and scintigraphic findings.

What movement does the interspinous ligament limit?

Primary Spinal Ligaments Include:

Ligament Spinal Region Limits…
Interspinous Lumbar Flexion
Intertransverse Lumbar Lateral flexion
Iliolumbar Sacroiliac joints Stability & some motion
Sacroiliac Sacroiliac joints Stability & some motion

How do you treat a thoracic sprain?


  1. Rest as directed. Move slowly and carefully.
  2. Apply ice or heat as directed. Ice decreases pain and swelling and may help decrease tissue damage.
  3. Use an elastic wrap or back brace as directed. These will help keep the injured area from moving so it can heal.
  4. Go to physical therapy as directed.

How much does kissing spine surgery cost for a horse?

Mostly due to the general anesthesia involved, the cost of this surgery is higher – around $2,500-$3,000, generally. And due to the level of invasiveness, the horse may take several weeks longer to recover once home.

Is kissing spine arthritis?

When two or more of these spinous processes are too close together, they may touch, which results in severe back pain from arthritic changes, inflammation, and even microfractures. These impinging spinous processes are called kissing spines.

How serious is a thoracic sprain?

When the thoracic or lumbar spine is strained or sprained, the soft tissues become inflamed. This inflammation causes pain and may cause muscle spasms. Thoracic or lumbar strain or sprain can be very debilitating.

What’s the success rate of interspinous ligament desmotomy?

Interspinous ligament desmotomy (ISLD) was first described in 2012 (Coomer et al., 2012) with a remarkable 95 percent success rate. A recent study found that 53 percent of horses are at equivalent or higher level of performance three years post ISLD (Prisk and García‐López, 2019).

How many horses have impinging spinous processes ( ISP )?

Impinging spinous processes (ISP) have been found in 86 to 92 percent of racehorses at post-mortem and in 37 percent of normal horses, so their presence radiographically is not necessarily associated with thoracolumbar pain.

How is pain attributed to a horse?

If the horse has a reproducible clinical sign, diagnostic analgesia is the most reliable way of attributing pain to a region. Infiltration of local anaesthetic between impinging spinous processes is commonly used; the author injects 10ml either side of the affected sites under radiographic guidance.

How are corticosteroids used to treat back pain in horses?

Corticosteroids are injected into the space between the dorsal spinous processes to reduce inflammation and pain. With this treatment, more than half of horses are expected to experience reoccurring back pain within the first year and require additional injections or treatment.
