Kissing spines, also known as overriding dorsal spinous processes (ODSP), is a common condition in horses that can lead to pain and performance issues. As a horse owner, understanding this condition is crucial for the health and well-being of your equine companion. In this blog, we will explore what kissing spines are, their symptoms, diagnosis, treatment options, and preventive measures.
What are Kissing Spines?
Kissing spines occur when the spinous processes of the vertebrae in a horse’s back come into contact with one another. This can lead to inflammation, pain, and discomfort, significantly affecting a horse's ability to perform and enjoy its work.
Symptoms of Kissing Spines
Recognising the symptoms of kissing spines is essential for early intervention. Common signs include:
Back Pain: Horses may exhibit signs of discomfort when pressure is applied to their back.
Changes in Behaviour: A horse may become more irritable or resistant to being saddled or ridden.
Altered Gait: Look for signs of lameness or a change in the horse's normal gait.
Difficulty with Lateral Movements: Horses may struggle with bending or turning.
Muscle Atrophy: Over time, you may notice a loss of muscle mass along the back.
Diagnosis of Kissing Spines
If you suspect your horse may have kissing spines, it is essential to consult with a veterinarian. The diagnosis typically involves:
Physical Examination: A thorough check for pain and sensitivity in the back area.
X-rays: Radiographs can confirm the presence of overriding spinous processes.
Ultrasound: This may be used to assess soft tissue involvement and inflammation.

Treatment Options
Treatment for kissing spines varies depending on the severity of the condition. Options include:
Conservative Management: This may involve rest, pain relief medications, anti-inflammatories, chiropractic care and rehabilitation
Physical Therapy: Techniques such as massage, chiropractic adjustments, and stretching exercises can help.
Injections: Corticosteroid injections may be used to reduce inflammation and pain.
Surgery: In severe cases, surgical intervention may be necessary to remove the affected spinous processes.
Preventive Measures
While not all cases of kissing spines can be prevented, there are steps you can take to minimise the risk:
Proper Saddle Fit: Ensure your saddle fits correctly to avoid undue pressure on the back.
Regular Check-Ups: Schedule routine visits from your McTimoney Animal Chiropractor to monitor your horse's back health.
Strengthening Exercises: Engage in exercises that build core strength and improve flexibility.
Warm-Up and Cool Down: Always warm up before riding and cool down afterwards to maintain muscle health.
Conclusion
Kissing spines can be a serious condition that affects your horse's comfort and performance. As a responsible horse owner, being aware of the symptoms and seeking prompt veterinary care can make a significant difference in your horse’s quality of life. By implementing preventive measures, you can help keep your horse healthy and happy.
