If you may be suffering from Kissing Spine, please Schedule an appointment with one of our Neurosurgeons as soon as possible.
What is Kissing Spine?
Kissing spine occurs when two or more of the small bony projections on the vertebrae, called spinous processes, lie so close together that they touch or rub against one another. This abnormal contact causes inflammation, pain, and changes in the surrounding bones and soft tissues. The condition most commonly affects the lower back in people, although veterinarians also commonly diagnose the condition in horses.
The contact between adjacent spinous processes can restrict normal spinal movement and produce pain, particularly during movements that extend the back. Some people have closely spaced spinous processes without symptoms, while others develop chronic back pain because repeated contact irritates the affected area. Kissing spine describes this structural abnormality of the spine, with symptoms ranging from none to persistent pain.
Symptoms of Kissing Spine
People with kissing spine often experience back pain that worsens during movements that increase contact between the affected spinous processes. Symptoms vary in severity depending on the degree of irritation and inflammation, and some people remain symptom-free despite having the condition. When symptoms develop, they can interfere with daily activities and reduce spinal mobility.
Symptoms may include:
- Localized pain in the affected area of the spine
- Pain that worsens when bending backward or extending the back
- Tenderness over the affected vertebrae
- Stiffness and reduced range of motion in the spine
- Muscle spasms or tightness in the back
- Pain during prolonged standing, walking, or physical activity
- Discomfort that improves with rest or forward bending
- Reduced ability to perform activities that require spinal extension
Causes of Kissing Spine
Several factors can contribute to the development of kissing spine by reducing the space between adjacent spinous processes. Age-related degeneration, repetitive stress on the spine, poor posture, and excessive spinal extension commonly increase pressure between these bony structures. Previous back injuries, degenerative disc disease, arthritis, and abnormal spinal alignment can also alter normal spinal mechanics and promote contact between the spinous processes. In some cases, congenital differences in spinal anatomy create a higher risk, while repeated physical activities that place excessive strain on the lower back may accelerate progression and worsen inflammation.
Treatment for Kissing Spine
Mild Cases:
Specialists usually begin treatment for mild kissing spine with conservative approaches that reduce pain and improve spinal function. Physical therapy strengthens the muscles that support the spine, improves posture, and increases flexibility while reducing pressure between the spinous processes. Activity modification, rest, nonsteroidal anti-inflammatory drugs (NSAIDs), and heat or ice therapy can help relieve pain and inflammation. Some patients also benefit from corticosteroid injections when persistent inflammation limits daily activities.
Severe Cases:
Severe kissing spine may require surgical treatment when conservative therapies fail to provide adequate relief or when chronic pain significantly affects quality of life. Neurosurgeons may remove part of the affected spinous process or perform other procedures that increase the space between adjacent vertebrae and reduce painful contact. Following surgery, patients typically participate in a structured rehabilitation program that restores strength, mobility, and spinal stability while supporting long-term recovery.
