Have you ever felt an unusual pain or stiffness when bending a joint or performing daily activities? Sometimes, after getting an X-ray, your doctor might mention, "You have a small bony growth." Medically, these are called osteophytes, but in common terms, they are known as "bone spurs." Don't be alarmed by the name—let's break down exactly what these are and how to manage them.
What exactly are bone spurs?
Simply put, these are smooth, hard pieces of bone that grow on the ends of your bones, especially where two joints meet. They look like a small mound or projection on the surface of the bone. In many cases, they don't cause any problems at all. However, if these spurs begin to rub against another bone, a nerve, or a tendon, that is when pain, stiffness, and discomfort usually start.
Bone spurs can develop in various parts of the body, such as:
- Hands
- Shoulders
- Neck
- Spine
- Hips
- Knees
- Heels
Many people don't even know they have them until they are discovered incidentally during an X-ray taken for an unrelated issue.
Why do bone spurs form?
The most common cause is the wearing down of joints, known as Osteoarthritis. Think of cartilage as a cushion—like a shock absorber in a vehicle—that sits between your joints to prevent bones from rubbing together and to help the joint move smoothly. As we age, gain weight, or use our joints over a long period, this cushion wears away.
When this happens, your body senses the damage and tries to "repair" the area. It attempts to strengthen the damaged region by growing extra bone. These new, extra bone growths are what we see as bone spurs.
Beyond this, there are several other factors:
- Other joint damage: Conditions like Rheumatoid arthritis, Lupus, or Gout can cause joint damage that leads to spurs.
- Injuries: After an injury to a joint or tendon, the body may form spurs while trying to heal the area.
- Overuse: If someone participates in activities like running or dancing for many years, the constant pressure on the joints can lead to their development.
- Genes: If someone in your family has them, you may be more prone to developing them as well.
- Obesity: Excess body weight puts significant pressure on your joints, particularly the knees and hips, accelerating wear and spur formation.
- Diet: Certain nutritional deficiencies may play a role.
- Spinal Stenosis: The narrowing of the path where spinal nerves travel can also lead to bone spurs in the spine.
What are the symptoms of bone spurs?
As mentioned, often there are no symptoms. However, if the spur grows large enough to compress a nerve, tendon, or nearby bone, you may experience the following:
| Symptom | Description |
|---|---|
| Joint pain | Pain occurring in or around the affected joint. |
| Joint stiffness | Difficulty or pain when trying to bend or move the joint. |
| Numbness or weakness | If a spinal bone spur presses on a nerve, you might feel numbness or weakness in your arms or legs. |
| Muscle spasms | Muscle cramps, pain, or weakness. |
| Bumps under the skin | Particularly in the hands and fingers, you may be able to feel or see lumps under the skin. |
Most importantly, these symptoms may worsen when you exercise or use the affected joint.
Sometimes, a piece of a bone spur can break off and become trapped within the joint. This is known as a "loose body." If this happens, the joint can become "locked," making it impossible to move.
How is it diagnosed?
If you have these symptoms, you should consult your primary care physician. They may refer you to a rheumatologist or an orthopedic specialist.
- Physical Exam: Your doctor will examine the joint to check for swelling, tenderness, or visible lumps.
- X-ray: This is the primary and simplest test to identify bone spurs, as they show up clearly on X-ray images.
- Other tests: Depending on the severity, you may need additional tests to check for nerve damage or soft tissue impact.
- CT Scan: This provides highly detailed cross-sectional images of the inside of your body.
- MRI Scan: Uses magnets and radio waves to create detailed images of bones, cartilage, tendons, and nerves.
- Electroconductive tests: These tests help determine if a nerve has been damaged by a bone spur.
Treatments and home care
If you don't have symptoms, treatment is usually unnecessary. However, if you are in pain or experiencing discomfort, your doctor may suggest the following treatments:
Pain and swelling management
Your doctor may recommend over-the-counter pain relievers like acetaminophen or ibuprofen to manage pain and swelling.
A word of caution: Never take pain relievers for a long period without medical supervision, as they can cause side effects. If you need to use them for more than a month, please speak with your doctor to discuss alternative treatment plans.
Other treatments
- Rest: Resting the affected joint is crucial when pain increases.
- Steroid shots: Your doctor may inject steroids directly into the joint to quickly reduce inflammation and pain.
- Physical therapy: This is a very effective treatment. A physical therapist can guide you through exercises to strengthen the muscles around the joint, improve your range of motion, and reduce pain.
Surgery
If conservative treatments do not work, or if the bone spur significantly restricts your daily activities, surgery to remove the extra bone growth may be the final option.
Can they be prevented?
While it is difficult to prevent bone spurs caused by natural wear and tear (osteoarthritis), you can reduce the risk of those caused by other factors:
- Wear good footwear: Choose shoes that aren't tight, provide ample room for your toes, support your arch, and have cushioning to absorb impact.
- Wear thick socks: These can help prevent shoes from rubbing against your skin.
- Proper exercise: Weight-bearing exercises like walking or climbing stairs help keep bones strong.
- Maintain a healthy weight: Losing excess weight reduces the pressure on your joints, which is one of the best ways to reduce the risk of developing bone spurs.
The most important thing is that if you have joint pain, swelling, or stiffness, do not ignore it—seek medical advice promptly. Early diagnosis and treatment can often prevent the type of damage that leads to bone spurs.
Take-Home Message
- Bone spurs are extra bone growths. They are often harmless.
- Pain only occurs if these spurs compress nerves, tendons, or other bones.
- The primary cause is osteoarthritis, which occurs as we age.
- Avoid long-term self-medication for pain. Always consult your doctor.
- Maintaining a healthy weight, wearing supportive footwear, and avoiding activities that damage your joints can help prevent them.
