Overview
Facet arthropathy is wear-and-tear arthritis of the spinal facet joints, which are small joints on the back of the spine that help guide motion. As these joints degenerate, the cartilage can thin, the joint capsule can become irritated, and bone spurs may form. This process can lead to back or neck pain and stiffness, especially with movements that load the joints, like bending backward or twisting. Some people may also feel pain that seems to radiate into the buttock or thigh, although true nerve symptoms depend on whether nearby structures are irritated or compressed.
Symptoms
Pain is often felt in the back or neck and may be worse with extending the spine backward, standing for long periods, or repeated twisting. You may notice stiffness, reduced range of motion, and soreness in the muscles alongside the spine. In the lumbar spine, discomfort can sometimes refer into the buttock and upper leg without following a clear nerve pattern. If facet irritation contributes to narrowing around nerve pathways, you may also experience tingling or burning, but this is not always present.
Causes
Facet arthropathy most commonly develops as part of normal aging and long-term mechanical stress on the spine. Disc degeneration, repeated micro-injury, poor spinal alignment, and higher loads (from heavy lifting, prolonged postures, or occupational demands) can accelerate facet joint wear. Less commonly, a prior injury to the spine or a congenital or acquired instability can change how forces are distributed across the facet joints. Over time, inflammation and structural changes within the facet joints can drive ongoing pain.
Risk Factors
Your risk increases with age because the facet joints naturally undergo degenerative changes. Occupations or activities that involve frequent bending, lifting, twisting, or long periods of standing or sitting can increase cumulative stress on the spine. Prior spinal injury, body weight that adds extra load to the spine, and reduced trunk strength or flexibility can make symptoms more likely and harder to control. Smoking can also negatively affect spinal health and tissue recovery.
Prevention
You can reduce flare-ups and slow progression by maintaining good trunk strength and mobility through safe, regular exercise and physical therapy. Using proper lifting and movement mechanics, avoiding prolonged sustained postures, and taking strategic breaks can lower repetitive stress on facet joints. Weight management and overall cardiovascular conditioning can reduce the load transmitted through the spine. A consistent home program for posture, core stabilization, and flexibility often helps keep symptoms from recurring.
How the Diagnosis Is Evaluated
Clinicians usually start with a history focused on when pain occurs, what motions worsen it, and whether symptoms follow a nerve distribution. A physical exam looks for tenderness over the facet region, pain reproduced with extension and rotation, and assessment of strength, sensation, and reflexes to rule out significant nerve involvement. Imaging such as X-ray or MRI may be used when symptoms are persistent, severe, or associated with neurologic findings, but degenerative findings alone do not always explain pain. To confirm the facet joints as the pain source, diagnostic medial branch blocks may be recommended in selected cases.
Nonsurgical Treatment Options
Treatment typically begins with activity modification and a structured physical therapy program focused on core and hip strength, postural control, and mobility while avoiding painful end-range movements. Over-the-counter or prescription pain relief may include acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs) when appropriate for your health profile, along with topical anti-inflammatories or heat therapy. If pain persists, clinicians may offer image-guided corticosteroid injections to the facet joints or targeted medial branch blocks to reduce inflammation and help identify the pain generator. For longer-term relief in properly selected patients, radiofrequency ablation of the medial branch nerves may be considered after successful diagnostic blocks. In some practices, platelet-rich plasma (PRP) is discussed as a non-surgical option, though evidence and availability vary by clinic and situation.
When to Seek Medical Attention
Seek prompt medical attention if you develop new or progressive weakness, numbness, trouble walking, or symptoms that rapidly worsen. Go urgently if you have bowel or bladder changes, saddle numbness, severe unrelenting pain, fever, unexplained weight loss, or a history of cancer. If pain follows a significant trauma or you cannot bear weight due to pain, you should be evaluated urgently. Otherwise, schedule a routine appointment if pain lasts beyond a few weeks, keeps returning, or limits daily activities despite home care.
Frequently Asked Questions
It often feels like aching or sharp pain in the neck or back that is worse with extension, standing, twisting, or certain positions.
Clinicians may use exam findings and imaging selectively, and diagnostic medial branch blocks can help confirm the facet joints are generating pain.
Next Steps
If your symptoms are persistent or recurring, consider an evaluation by a clinician or physical therapist to confirm the pain source and start a tailored exercise plan. If you have neurologic symptoms or pain is severe, seek medical care sooner so appropriate imaging and testing can be considered. A stepwise approach-starting conservatively and escalating only when needed-often provides the best results.
