There are a variable number of bursae in the spinal column. They are normally located between the spinous processes of the cervical and lumbar segments. Bursitis of these structures can result in neck or back pain. In the neck, interspinous bursitis has been associated with several rheumatological conditions such as polymyalgia rheumatica, rheumatoid arthritis, and crystalopathies. In the lumbar spine the condition is also known as "kissing-spine" disease and occurs in the context of degenerative change.
