Osteophytes are bony lumps (bone spurs) that grow on the bones of the spine or around the joints.
They often form next to joints affected by osteoarthritis (a condition that causes joints to become painful and stiff).
Osteophytes can grow from any bone, but they're most often found in the:
Osteophytes don't always cause symptoms. They can cause problems if they:
For example, osteophytes that occur in the:
Osteophytes tend to form when the joints have been affected by arthritis.
Osteoarthritis damages cartilage, which is the tough, white, flexible tissue that lines the bones and allows the joints to move easily.
Osteoarthritis mostly occurs in the knees, hips, spine and small joints of the hands and base of the big toe.
As the joints become increasingly damaged, new bone may form around the joints. These bony growths are called osteophytes.
Osteophytes can also form in the spine as a result of ankylosing spondylitis (a type of arthritis that specifically affects the spine).
See your GP if you have joint pain or stiffness, or if you have other symptoms in an area of your body, such as numbness or nerve pain. They'll investigate the underlying cause.
Your GP will ask you about your symptoms and they may examine the affected area. They may test your joint movements and muscle strength. They'll also look at your medical history.
Osteophytes don't usually cause pain, but the associated arthritis might.
If you're in pain, over-the-counter painkillers, such as paracetamol or ibuprofen, may help. Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID), which can also help reduce any swelling and inflammation.
If you're overweight, losing weight will help by relieving some of the strain on your joints.
A physiotherapist may also be able to help you by recommending exercises that can strengthen the muscles surrounding the problem area, and by helping to improve your range of movement.
Surgery can sometimes be used to help manage any underlying arthritis in the joint. It can be helpful for osteoarthritis that affects your hips, knees or joints, particularly those at the base of your thumb.

There's usually no need to remove an osteophyte, unless it's irritating a nerve in the spine or restricting a joint's range of movement. If you do need surgery to remove an osteophyte, your surgeon will explain the procedure's risks and benefits.
