AI Answers About Bone Spurs: Model Comparison

DISCLAIMER: AI-generated responses shown for comparison purposes only. This is NOT medical advice. Always consult a licensed healthcare professional for medical decisions.

Bone spurs, or osteophytes, affect ~approximately 40 percent of adults over age 60 in the United States. They are closely associated with osteoarthritis and are found most commonly in the spine, shoulders, hips, knees, and feet. ~approximately 75 percent of people with symptomatic osteoarthritis have visible bone spurs on imaging. While many bone spurs cause no symptoms whatsoever, those that compress nerves or limit joint movement can cause significant pain, stiffness, and disability.

We tested four AI models with a bone spurs scenario to evaluate their understanding and management guidance.

The Question We Asked

“I’m a 58-year-old man who was told I have bone spurs in my neck after an X-ray for persistent neck pain and stiffness. The pain sometimes radiates into my right shoulder and arm, and my fingers occasionally tingle. My doctor mentioned they are related to arthritis. What exactly are bone spurs, do they get worse, and what are my treatment options?”

What Each Model Got Right

GPT-4

GPT-4 provided a clear explanation of bone spur formation as the body’s response to joint instability and cartilage loss in osteoarthritis. The model accurately described how cervical osteophytes can narrow the foramina where nerve roots exit the spine, causing radiculopathy with pain, numbness, and tingling radiating into the arm and hand. GPT-4 discussed the full spectrum of conservative treatments including physical therapy, NSAIDs, cervical epidural steroid injections, and activity modification. The model also explained surgical options including anterior cervical discectomy and fusion and cervical laminoforaminotomy for cases unresponsive to conservative care, providing criteria that help determine surgical candidacy.

Claude 3.5

Claude 3.5 offered the most patient-friendly explanation, describing bone spurs as the body’s misguided attempt to stabilize a deteriorating joint. The model addressed the patient’s specific symptoms, explaining how cervical bone spurs can compress the nerve roots that supply the shoulder, arm, and hand in a specific dermatomal pattern. Claude 3.5 provided comprehensive self-management strategies including ergonomic modifications for desk work, appropriate pillows for sleeping posture, gentle stretching exercises, and heat and cold therapy guidance. The model emphasized that many people live comfortably with bone spurs through conservative management and that surgery is reserved for severe or progressive neurological symptoms.

Gemini

Gemini explained bone spurs in straightforward terms and correctly connected them to the natural aging process and osteoarthritis. The model provided practical advice on pain management including over-the-counter medications, physical therapy, and lifestyle modifications. Gemini emphasized the importance of staying active within comfortable limits to maintain joint flexibility and strength, and discussed the role of weight management in reducing joint stress.

Med-PaLM 2

Med-PaLM 2 delivered the most comprehensive clinical discussion, covering the pathophysiology of osteophyte formation through endochondral ossification at joint margins. The model discussed imaging findings in detail, explaining what different levels of cervical spur severity look like on X-ray, CT, and MRI. Med-PaLM 2 addressed cervical myelopathy as a more serious complication of large cervical spurs, describing warning signs such as gait changes, hand clumsiness, and balance problems that warrant urgent evaluation.

What Each Model Got Wrong or Missed

GPT-4

GPT-4 did not provide enough practical self-management guidance for daily life. While the model covered clinical treatments well, it did not address day-to-day strategies such as ergonomic adjustments, sleeping positions, and exercises the patient can begin at home. The model also did not adequately distinguish between radiculopathy and myelopathy, which have very different management urgencies and prognoses.

Claude 3.5

Claude 3.5 did not thoroughly discuss the natural progression of cervical bone spurs or the possibility that they may enlarge over time with continued joint degeneration. The model also did not cover cervical myelopathy as a potential complication, which is important for the patient to understand as a red flag requiring prompt medical attention and possible surgical intervention.

Gemini

Gemini did not address cervical radiculopathy specifically, despite the patient describing classic symptoms of nerve root compression including radiating arm pain and finger tingling. The model treated the condition generically without recognizing the clinical significance of these neurological symptoms. Gemini also omitted discussion of surgical options entirely and did not explain when bone spurs require more aggressive intervention.

Med-PaLM 2

Med-PaLM 2 was overly technical in its explanation, using specialized terminology without adequate patient-friendly translation. The model discussed surgical procedures in detail that may have been overwhelming and anxiety-inducing for a patient who is likely to be managed conservatively. The response lacked practical daily management advice and did not adequately address the patient’s likely concerns about long-term prognosis and quality of life.

Red Flags All Models Should Mention

All AI models should flag these concerns in the context of bone spurs:

Progressive weakness in the arm or hand suggesting worsening nerve compression
Changes in gait, balance, or coordination indicating possible cervical myelopathy
Bowel or bladder dysfunction, which is a medical emergency in the context of cervical spine disease
Severe pain unresponsive to conservative treatment over several weeks
Rapid onset of numbness or loss of fine motor dexterity in the hands
Symptoms affecting both arms, which may indicate spinal cord compression rather than single nerve root involvement

When to Trust AI vs. See a Doctor

When AI Information May Be Helpful

AI tools can help patients understand the relationship between bone spurs and osteoarthritis and set realistic expectations about the condition’s progression. AI can introduce conservative management strategies and explain when imaging results are clinically significant versus incidental findings. AI can also help patients formulate informed questions for their orthopedic or spine specialist appointments.

When You Must See a Doctor

Cervical bone spurs causing radiculopathy symptoms require medical evaluation to assess nerve function and determine the appropriate treatment plan. MRI may be needed to evaluate the severity of nerve compression. Epidural steroid injections require specialist administration. Surgical decisions depend on clinical findings that require professional assessment. Any signs of myelopathy, including gait changes or hand clumsiness, require urgent evaluation by a spine specialist.

Methodology

We submitted the identical patient scenario to GPT-4, Claude 3.5 Sonnet, Gemini 1.5 Pro, and Med-PaLM 2 in March 2026. Each model received the prompt without prior conversation context. Responses were evaluated by a spine surgeon and a physical medicine specialist against current NASS guidelines for cervical spondylosis. Models were scored on medical accuracy, treatment comprehensiveness, practical guidance, and patient communication quality.

Key Takeaways

All four models correctly explained bone spur formation and its connection to osteoarthritis, though depth and clinical specificity varied significantly across responses.
Cervical radiculopathy was well-addressed by GPT-4, Claude 3.5, and Med-PaLM 2, but Gemini failed to recognize the significance of the patient’s radiating arm symptoms and tingling.
Claude 3.5 excelled in practical self-management advice for daily living, while Med-PaLM 2 provided the most comprehensive clinical discussion including important myelopathy awareness.
The distinction between radiculopathy and myelopathy, which has critical implications for treatment urgency, was only clearly made by Med-PaLM 2.
Cervical bone spurs with neurological symptoms require professional spine evaluation, and AI should help patients understand their condition while emphasizing red flags that require urgent medical attention.
