A bone spur in the neck is a small, bony projection that grows along the edges of the vertebrae in your cervical spine. These growths, called osteophytes, develop gradually as part of the body’s response to wear and tear on the spinal discs and joints. Most bone spurs cause no symptoms at all. In fact, MRI studies of adults over age 75 show that roughly 94% have bone spurs in their cervical spine, and the vast majority never know it.
When bone spurs do cause problems, it’s because they’ve grown large enough to press on a nerve or crowd the spinal cord. That’s when neck pain, numbness, or difficulty with coordination can develop.
How Bone Spurs Form
The discs between your neck vertebrae lose water content and flatten as you age. This changes how weight and force are distributed across the spine. Bone spurs appear to be the body’s attempt to re-balance that load, essentially building extra bone to stabilize a joint that’s becoming less cushioned. The process involves stem cells near the joint surface that get activated and begin forming new bone and cartilage, using the same biological pathways your skeleton used when it first developed in the womb.
This means bone spurs aren’t random deposits. They contain active, living bone tissue with regions of cartilage, fibrous tissue, and bone marrow. They grow slowly over years or decades, which is why they’re far more common in older adults, though they can appear earlier in people with spinal injuries, poor posture, or jobs that put repetitive stress on the neck.
Common Causes
The primary driver is osteoarthritis of the cervical spine, sometimes called cervical spondylosis. As the cartilage cushioning the facet joints wears down, bone responds by growing outward. Degenerative disc disease accelerates this: as discs thin, the vertebrae shift closer together, increasing friction and triggering spur formation at the disc margins.
Other contributing factors include prior neck injuries (even old whiplash), inflammatory conditions like ankylosing spondylitis, and genetics. Spending long hours with your head tilted forward, whether at a desk or looking at a phone, increases the mechanical load on the cervical spine and can speed up degeneration over time.
Symptoms That Signal a Problem
A bone spur sitting quietly on the edge of a vertebra won’t cause any symptoms. Problems start when a spur grows into a space occupied by nerves or the spinal cord. There are two main patterns.
Nerve Root Compression
When a bone spur narrows the foramen, the small opening where a nerve exits the spine, it can pinch that nerve root. This is called cervical radiculopathy. The symptoms follow the path of the affected nerve: pain that radiates from the neck into the shoulder, arm, or hand, along with tingling or numbness in specific fingers. For example, a spur compressing the nerve at the C7 level typically causes weakness when extending the wrist and tingling in the index, middle, and ring fingers. A C8 compression affects grip strength and causes numbness in the little finger.
Spinal Cord Compression
This is more serious. When bone spurs narrow the spinal canal itself, they can press on the spinal cord, a condition called cervical myelopathy. The symptoms are often subtle at first: clumsiness in the hands, difficulty with fine motor tasks like buttoning a shirt or holding a cup, and an unsteady walk. People often describe feeling less coordinated without being able to pinpoint why. Numbness and tingling in both the hands and feet can develop, and in severe cases, bladder or bowel function can be affected. Because the onset is gradual, many people attribute these changes to “just getting older” before the real cause is identified.
Less commonly, large bone spurs growing toward the front of the spine can press on the esophagus or airway, causing difficulty swallowing, voice changes, or breathing issues during sleep.
How Bone Spurs Are Diagnosed
Standard X-rays can reveal bone spurs and show how much disc space has been lost. Flexion and extension X-rays, taken while you bend your neck forward and backward, help determine whether the affected vertebrae are still moving normally or have become unstable.
MRI provides a more detailed picture, showing soft tissues like discs, nerves, and the spinal cord alongside the bony changes. It’s the best tool for determining whether a bone spur is actually compressing a nerve or the spinal cord. CT scans are sometimes added when the bony anatomy needs to be seen in finer detail, particularly to evaluate spurs on the small joints along the sides and back of the vertebrae, or to rule out calcification of the ligaments running behind the vertebral bodies.
One important caution: imaging findings don’t always match symptoms. Many people with prominent bone spurs on MRI have no pain, and some people with significant pain have only modest imaging findings. A thorough physical exam remains essential for connecting what the images show to what you’re actually experiencing.
Non-Surgical Treatment
Most symptomatic bone spurs in the neck improve with conservative treatment. The spur itself doesn’t go away, but the inflammation and nerve irritation around it can be reduced enough that symptoms resolve or become manageable.
First-line options include over-the-counter anti-inflammatory pain relievers, periodic icing of the neck, and short rest periods between activities that aggravate symptoms. Physical therapy plays a central role: a therapist can work on posture correction, neck strengthening, and gentle stretching to take pressure off compressed nerves. For people whose posture has shifted to compensate for pain, manual manipulation can help restore more balanced alignment.
When these approaches aren’t enough, cortisone injections can deliver targeted anti-inflammatory relief directly to the area around the affected nerve. Prescription muscle relaxants are sometimes used short-term if neck muscle spasms are contributing to pain. For bone spurs affecting swallowing, modifications like changing food textures and adjusting head position while eating can reduce symptoms enough to avoid surgery.
When Surgery Becomes Necessary
Surgery is typically reserved for cases where conservative treatment has failed after a reasonable trial, or where neurological deficits are progressing. Signs of worsening spinal cord compression, such as increasing clumsiness, gait problems, or changes in bladder function, generally warrant surgical evaluation sooner rather than later because spinal cord damage can become permanent if left too long.
One common approach is a cervical laminoforaminotomy, a minimally invasive procedure often done on an outpatient basis. Through a small incision on the back of the neck, the surgeon shaves away a thin layer of the lamina (the bony plate protecting the spinal cord) and removes the bone spur and any disc material crowding the nerve. For more extensive compression, a procedure called anterior cervical discectomy and fusion (ACDF) removes the disc and spur from the front of the spine and fuses the adjacent vertebrae together. Disc replacement is an alternative that preserves motion at the treated level.
Recovery is faster than many people expect. Studies tracking patients after both fusion and disc replacement surgery found that the majority returned to driving within about two weeks and were back at work within roughly the same timeframe. Most patients stopped needing pain medication within six to seven days after surgery.
What Happens if You Leave Them Alone
Bone spurs that aren’t causing symptoms don’t need treatment. They may never cause problems, and having them on an X-ray or MRI doesn’t mean you’ll develop pain or nerve issues down the road.
Symptomatic bone spurs are a different matter. When a spur is compressing a nerve root, the pain and tingling can often be managed conservatively, and many people find that symptoms improve over weeks to months. But when a spur is compressing the spinal cord, the stakes are higher. Prolonged spinal cord compression can cause weakness and numbness in the arms and legs that may not fully reverse even after the pressure is relieved surgically. That’s why progressive neurological symptoms, especially difficulty with balance, hand coordination, or bladder control, warrant prompt evaluation rather than a wait-and-see approach.
