What are osteophytes?

From the Guidelines

Osteophytes are bony projections that form along joint margins as a result of wear and tear on the joint, and they can cause pain, stiffness, or reduced range of motion if they press on nerves or restrict joint movement. When explaining osteophytes to a patient, it's essential to note that they are small, smooth outgrowths of bone that the body creates in response to joint damage or arthritis, as seen in the patient's case with moderate to severe tricompartmental degenerative changes and osteophyte formation 1. These bone spurs often form in joints affected by osteoarthritis, particularly in the spine, hips, knees, fingers, and feet.

Some key points to consider when discussing osteophytes with a patient include:

• Osteophytes can develop as the body attempts to repair itself when cartilage wears down, causing bones to rub against each other 1
• While many osteophytes cause no symptoms, some can lead to pain, stiffness, or reduced range of motion if they press on nerves or restrict joint movement
• Treatment depends on the patient's symptoms and may include pain medications like acetaminophen or NSAIDs (ibuprofen, naproxen) at standard doses, physical therapy to strengthen surrounding muscles, steroid injections to reduce inflammation, or in severe cases, surgical removal, as recommended by the American College of Rheumatology 1
• Maintaining a healthy weight, staying physically active with low-impact exercises, and using proper body mechanics can help manage symptoms and prevent further joint damage, as seen in the patient's case where she was able to decrease her body mass index to 28 while also strengthening her quadriceps 1

It's also important to note that the development of osteophytes is often part of the natural aging process, but factors like joint injuries, obesity, and genetic predisposition can accelerate their formation, as mentioned in the study by the American Academy of Orthopaedic Surgeons 1. By understanding the causes and symptoms of osteophytes, patients can better manage their condition and prevent further joint damage.

From the Research

Explanation of Osteophytes

• Osteophytes are fibrocartilage-capped bony outgrowths that are a feature of osteoarthritis, as stated in the study 2.
• They can be classified into different types, including marginal, central, periosteal, or capsular for extraspinal osteophytes, and traction or claw for vertebral osteophytes 2.
• Risk factors for the development of osteophytes include age, body mass index, physical activity, and genetic and environmental factors 2.

Symptoms and Treatment of Osteophytes

• Osteophytes can cause pain, limit range of motion, affect quality of life, and cause multiple symptoms at the spine 2.
• Medical treatment for osteophytes involves the use of bisphosphonates and other non-steroidal anti-inflammatory agents 2.
• Surgical treatment, such as cheilectomy for impingement syndromes during joint replacement, may be recommended in some cases 2.
• Other studies have investigated the use of intra-articular corticosteroids, hyaluronic acid, and platelet-rich plasma (PRP) for the treatment of osteoarthritis, with varying degrees of success 3, 4.

Management of Osteoarthritis

• The management of osteoarthritis is a complex and evolving field, with various pharmaceutical treatments available, including oral and topical nonsteroidal anti-inflammatory drugs (NSAIDs), COX-2 inhibitors, and intra-articular corticosteroids 5.
• Ibuprofen has been found to be effective in improving pain and function in patients with knee and hip osteoarthritis, with approximately 50-60% improvement over placebo in WOMAC scores 6.
• Other treatments, such as capsaicin, tramadol, and acetaminophen, are more controversial, and updated guidelines offer differing recommendations 5.
