What it is (overview)

A Cervical Spine X-Ray (AP & Lateral) is a common diagnostic imaging test that uses a small amount of ionizing radiation to create pictures of the bones in your neck (the cervical spine). “AP” stands for anteroposterior, meaning the X-ray beam passes from front to back, and “lateral” means the image is taken from the side. Together, these two views help the clinician evaluate the vertebrae (neck bones), the overall spinal alignment, and the spaces between the bones.

This test does not directly measure pain or nerve function—it shows the structure of the neck. It can reveal problems such as fractures, dislocations, abnormal curvature, and signs of degenerative changes (wear-and-tear arthritis). In many cases, it may also suggest issues like reduced disc height or bone spurs, which can sometimes relate to stiffness, reduced range of motion, or symptoms that travel into the shoulder or arm.

Results are usually reported as “normal” or they may describe findings such as straightening of the normal neck curve, misalignment, narrowing between vertebrae, osteophytes (bone spurs), or evidence of a break. A normal X-ray generally means there is no visible fracture or major alignment problem; however, some causes of neck pain (like muscle strain, ligament injury, or early disc problems) may not show up on X-ray. If symptoms are severe or persist, your clinician may recommend additional tests such as CT or MRI.

When & why it's usually done

Healthcare providers commonly order a cervical spine X-ray when someone has neck pain or a neck injury and they need a quick look at the bony structures. It is often used to check for injury after trauma and to assess chronic or worsening symptoms that may be related to arthritis or changes in the vertebrae.

This test is usually done to:

Evaluate trauma or possible fracture after events such as a fall, sports injury, workplace injury, or motor vehicle collision (including suspected whiplash). It can help detect fractures, dislocations, and abnormal spinal alignment that may require urgent care.

Investigate persistent or recurrent neck symptoms such as ongoing neck pain, stiffness, reduced range of motion, or pain that worsens with certain movements. X-rays can show degenerative changes in the cervical spine that may contribute to symptoms.

Assess posture and alignment issues when there is concern for abnormal curvature or shifting of vertebrae, especially if symptoms are accompanied by headaches, limited neck mobility, or visible changes in posture.

Follow known spine conditions to monitor progression of degenerative disease, stability after an injury, or changes over time. In some cases, it may also be used in pre-operative planning or post-treatment checks (based on clinician guidance).

Tell your radiology team if you are pregnant or might be pregnant. While X-rays use low doses and the neck is far from the abdomen, pregnancy precautions are still important. Also inform them about prior neck surgery or implanted hardware, since this can affect how images look.

Common diseases related to it

• Cervical spondylosis (age-related degenerative changes/arthritis of the cervical spine)
• Degenerative disc disease (suggested by disc space narrowing and related bony changes)
• Cervical spine fractures (from trauma such as falls or car accidents)
• Whiplash-associated disorders (X-ray may help rule out fracture or major instability)
• Spondylolisthesis (slippage/misalignment of one vertebra over another)
• Spinal stenosis (may be suggested by degenerative changes; MRI/CT often needed for confirmation)
• Osteoarthritis of the facet joints (a common cause of neck stiffness and pain)
• Kyphosis or loss of normal cervical lordosis (abnormal curvature or straightening of the neck)
• Ankylosing spondylitis or other inflammatory arthritis (may show characteristic bony changes over time)

Health goals where it may help

• Identifying the cause of neck pain by evaluating the cervical spine vertebrae and spinal alignment
• Ruling out serious injury (such as fractures or dislocations) after a neck injury or trauma
• Guiding treatment decisions for physical therapy, activity modification, pain management, or referrals to spine specialists
• Monitoring degenerative changes in the cervical spine over time (arthritis, disc space narrowing, bone spurs)
• Supporting safe return to activity after injury by documenting stable alignment and healing (as directed by a clinician)
• Planning further evaluation (helping decide if CT or MRI is needed for nerves, discs, or soft-tissue concerns)
