Quick Answer: What is cervical kyphosis?
Cervical kyphosis is a rare condition in which the neck's seven vertebrae become abnormally straight or curve forward instead of their natural backward curve. [4] Causes include degenerative disc disease, ankylosing spondylitis, trauma and prior spine surgery. [4] Pressure on nerves can cause weakness and numbness. [4] It is reversible with physical therapy in mild cases and surgery in severe ones. [4]
Key takeaways
Cervical kyphosis means the neck has lost its natural backward curve (lordosis) and either sits straight or bends forward. [4] The result can range from no symptoms at all to serious nerve compression that changes how you walk, move your hands, and even look at the world.
The cervical spine has 7 vertebrae with cushioning discs between them, supported by muscles and ligaments that keep the bones aligned and the neck flexible. [4]
The neck curve sets your natural gaze level. [4] In severe cases, kyphosis can tilt your gaze permanently downward.
Cervical kyphosis is a rare condition that can affect both children and adults. [4]
Causes include ankylosing spondylitis, degenerative disc disease, birth defects of the spine, tumors, trauma, and prior spine surgery, including laminectomy, a procedure meant to relieve pressure that can unintentionally change how the head is supported. [4]
Symptoms are linked to pinched nerves (radiculopathy) and spinal cord compression (myelopathy): reduced neck motion, swallowing difficulty, headaches, unstable walking, loss of hand dexterity, muscle weakness, pain, poor bladder or bowel control, and tingling or numbness. [4]
Mild cases are treated without surgery using medication and physical therapy, including neck exercises and traction. Therapy works for many people but not all. [4]
Surgery is recommended when pain or neurological symptoms appear, and can be performed from the back of the neck, the front near the throat, or both, using plates, rods, and screws. [4]
The forward curve is reversible, and correcting it can drastically improve quality of life. [4]
Some straightening of the neck spine happens naturally with age. Prevention focuses on regular physical activity and avoiding excessively large pillows. [4]
What the research says
Surgery can restore alignment and function in children. In a retrospective series of 16 patients aged 18 or younger with cervical kyphosis (mean age 14.2 years, most with a syndrome or prior trauma), surgical correction improved the Nurick grade from 2.8 to 1.8 and the modified Japanese Orthopaedic Association (mJOA) score from 11.3 to 14, and reduced the Cobb angle (the measure of the curve) from 40.7 degrees to 14.9 degrees. Early complications were hemodynamic instability during surgery in 3 patients and a wound complication in 1, over a mean follow-up of 76.9 months. This was a small single-center study combined with a literature review (Kumarasamy et al., Spine Deform, 2024). [1]
Combining front and back approaches corrects more but carries more risk. A review comparing surgical strategies found that the combined anterior and posterior approach achieved greater correction and was more likely to restore a normal inward curve, but it carried higher rates of postoperative neurological deterioration, complications, revision surgery, and mortality than the anterior-only approach. The authors recommend planning surgery for each person individually and note that no randomized trial has settled the question (Han et al., Eur Spine J, 2011). [2]
A multicenter study found the same trade-off. In 17 children with cervical kyphosis from three spine centers (mean age 11.9 years), 14 had surgery, 1 was treated with a Minerva brace, and 2 were observed. Over a mean follow-up of 32.4 months, combining anterior and posterior surgery gave significantly greater correction than either approach alone (P = 0.014). Neck pain and myelopathy were the most common symptoms (Alfawareh et al., Spine Surg Relat Res, 2024). [3]
What Is Cervical Kyphosis?
The spine is not one long straight column. Each section has its own natural curve, and the neck section, called the cervical spine, normally curves gently toward the back of the body. This backward curve is called lordosis. In cervical kyphosis, that curve is lost. [4] The neck spine becomes abnormally straight, or worse, it curves in the opposite direction, toward the front of the body. [4]
The shape of your neck matters more than it might seem. Your neck's curve determines the level of your natural gaze, which is where your eyes rest when you look straight ahead. [4] When the curve reverses into a forward bend, the head tilts forward with it. In severe cases, a person's gaze is tilted permanently downward.
Because the posture resembles the stiff, upright neck of a soldier at attention, cervical kyphosis is also commonly called "military neck." [4]
Some straightening of the cervical spine happens naturally as you get older. [4] But a true kyphotic curve, one that bends toward the front, is a distinct medical condition that deserves attention, especially when it causes pain or nerve problems.
Cervical Kyphosis Symptoms
Cervical kyphosis does not always cause symptoms. Whether you feel anything depends on the severity of the curve and how much pressure it puts on nearby structures. When symptoms do appear, they are frequently related to two mechanisms: pinched nerves (radiculopathy) and spinal cord compression (myelopathy). [4]
Symptom | What it looks like |
Decreased range of motion | Difficulty turning or tilting the head and neck; in permanent cases, a permanently downward gaze |
Difficulty swallowing (dysphagia) | Trouble getting food or liquid down normally |
Headache | Pain in the head that may radiate from the strained neck |
Instability when walking | Unsteady gait, balance problems, or difficulty coordinating steps |
Loss of fine motor function in hands | Trouble with precise hand tasks like buttoning clothing or writing |
Muscle weakness | Weakness in the shoulders, arms, or hands |
Pain | Pain in the neck, back, shoulders, or arms |
Poor bladder or bowel control | Reduced control over urination or bowel movements |
Tingling or numbness | Pins-and-needles sensations in the shoulders, arms, or hands |
Note that some symptoms, such as loss of bladder or bowel control and walking instability, can be signs of spinal cord compression (myelopathy), and it's important to seek care if you notice them. [5]
What Causes Cervical Kyphosis?
Several conditions can change how the neck spine is shaped or supported, pushing it out of its natural backward curve.
Cause | How it leads to kyphosis |
Ankylosing spondylitis | An inflammatory condition that causes the vertebrae to fuse together, locking the spine in an abnormal shape |
Degenerative disc disease | The discs between the vertebrae wear down over time, changing how the bones stack and curve |
Spinal abnormalities present at birth | Structural differences in the spine exist from birth |
Spine tumors | Growths in the spine alter bone structure and alignment |
Trauma or injury of the spine | Physical damage changes how the cervical vertebrae sit |
Prior spine surgery | Previous operations can alter the mechanics of the neck |
Laminectomy | Surgery to relieve compression (often from spinal stenosis) removes part of the bone (the lamina), changing how the head is supported and allowing the head's weight to shift forward and progress the kyphotic deformity |
The laminectomy connection is worth understanding. Laminectomy removes the back part of a vertebra to take pressure off the spinal cord. But removing that supporting bone can change how your head rests on the cervical spine. Without the usual support, the weight of the head shifts forward, and over time that forward pull can progress the kyphotic deformity. [4]
Who Is at Risk?
Cervical kyphosis is a rare condition. It can occur in both children and adults. [4] Risk comes less from who you are and more from what your spine has been through: injury, degeneration, inflammatory disease, or surgery.
How Is Cervical Kyphosis Diagnosed?
Diagnosis starts with a conversation about your medical history and symptoms, followed by a physical exam in which the provider checks your balance, movement, posture, reflexes, and strength. [4]
Imaging confirms the picture:
Test | What it shows |
X-ray | The overall alignment and curve of the cervical spine |
MRI | Detailed images of the spinal cord, nerves, and soft tissues to detect compression |
CT scan | Cross-sectional bone images for precise structural detail |
Cervical Kyphosis Treatment
Treatment depends on how severe the curve is and whether it is causing symptoms.
Nonsurgical Treatment (Mild Cases)
Mild cervical kyphosis is usually managed without surgery. Medications reduce pain and inflammation. [4] Physical therapy uses neck exercises or traction to relieve pain and may restore the normal neck curve. [4] Physical therapy may not work for everyone.
Surgical Treatment (Severe or Progressive Cases)
Surgery is recommended when the kyphosis causes pain or neurological symptoms, such as muscle weakness, tingling, or coordination issues. [4] The type of surgery depends on whether the spine is flexible or rigid. A spine stiffened by ankylosing spondylitis, for example, is treated differently from a flexible curve. [2] [4]
Approach | Where it's performed |
Posterior | Through the back of the neck |
Anterior | Near the throat |
Combined anterior + posterior | Both areas, for complex corrections |
During the operation, surgeons may cut away or remove portions of bone and use metal plates, rods, and screws to hold the spine in its corrected position. [4] The three surgical goals are to relieve compression of the spinal cord and nerves, restore the shape of the spine, and stabilize the spine. [4]
Recovery and Prognosis After Surgery
After surgery, you can expect a hospital stay, a period of rest, and limited movement while your provider tracks recovery closely. Physical therapy may then help you move better with less pain. [4]
Like all major procedures, cervical kyphosis surgery carries risks: infection, bleeding, blood clots, anesthesia reactions, and the added risk of spinal cord injury. Because the spine runs from the head to the pelvis as one connected structure, correcting one section may lead to problems elsewhere along the chain. [4]
Despite these risks, the overall outlook is encouraging: most children and adults do well with surgery, and realigning the spine and reducing pain can drastically improve quality of life.
Can Cervical Kyphosis Be Prevented?
In many cases, cervical kyphosis cannot be prevented, especially when it stems from trauma, birth abnormalities, tumors, or the after-effects of surgery. [4]
There are steps you can take in specific situations, however:
If you have ankylosing spondylitis or degenerative disc disease, talk with your provider about physical therapy and appropriate exercise. Regular physical activity reduces pain, increases strength and flexibility, and helps prevent further deterioration. [4]
Avoid excessively large pillows when sleeping on your back. A very tall pillow bends the neck forward during sleep, which can increase neck flexion in a harmful way over time. [4]
Can Cervical Kyphosis Be Reversed?
Yes. The forward curve is reversible. Physical therapy can be effective in mild cases, and surgery can correct the curve in severe kyphosis and relieve its symptoms. [4] Untreated, however, the condition can cause pain, disability, and decreased quality of life. [4] If your neck has lost its curve, talking to your provider about your options is the best first step.
Living With Cervical Kyphosis
Living with cervical kyphosis means paying attention to how your neck affects your daily life: how far you can turn your head, whether swallowing feels normal, and whether your hands are losing strength or coordination. Early evaluation matters, because the same condition that causes mild stiffness today can press on the spinal cord years from now.
When to Call a Doctor
Contact a healthcare provider if you notice changes in your walking, loss of balance or clumsiness, new or worsening neck pain, or numbness, tingling or weakness in your hands or fingers. [5] Loss of bladder or bowel control is also a symptom of spinal cord compression (myelopathy). [5] If you have cervical kyphosis, talk to your provider about your treatment options. [4]
Conclusion
Cervical kyphosis is a rare but meaningful change to the shape of your neck spine. Whether it comes from disc degeneration, an inflammatory disease, injury, or surgery, the consequences of a reversed neck curve extend far beyond posture. They can affect your gaze, your balance, your hands, and your quality of life. The good news is that the curve is reversible. Mild cases often respond to medication and physical therapy, and surgical options for severe cases aim to relieve pressure, restore the spine's shape, and stabilize the neck for the long term. Understanding the warning signs of pain, swallowing difficulty, numbness, weakness, and an unsteady gait puts you in a strong position to catch the condition early and protect your mobility.

Frequently Asked Questions
What is cervical kyphosis?
Cervical kyphosis is a rare condition in which the cervical spine, the seven vertebrae of the neck, loses its natural backward curve (lordosis) and instead sits straight or curves toward the front of the body.
What is cervical kyphosis also called?
Cervical kyphosis is commonly called "military neck" because the stiff, straight-necked posture resembles a soldier at attention.
Why is it called military neck?
The straightened, rigid neck posture looks like the upright head position of a military soldier standing at attention.
What does a normal cervical spine look like?
The normal cervical spine curves gently toward the back of the body (lordosis). The neck has seven vertebrae with cushioning discs between them, held in place by muscles and ligaments.
What does kyphosis mean in general?
Kyphosis describes a curve that bends toward the front of the body, the opposite of the normal cervical curve, which bends toward the back.
What is lordosis?
Lordosis is the natural inward curve of the cervical spine, opening toward the back of the body. Cervical kyphosis is the loss of this lordosis.
Is cervical kyphosis the same as cervical lordosis?
No. Lordosis is the normal curve. Kyphosis is the abnormal straightening or forward bending that replaces it.
Is some straightening of the neck normal?
Yes. Some straightening of the cervical spine happens naturally with age. True kyphosis, bending toward the front, is a distinct condition.
How rare is cervical kyphosis?
Cervical kyphosis is a rare condition that can occur in both children and adults.
Can children get cervical kyphosis?
Yes. It can occur in children as well as adults, particularly when spinal abnormalities are present at birth.
What causes cervical kyphosis?
Causes include ankylosing spondylitis, degenerative disc disease, spinal abnormalities present at birth, spine tumors, trauma or injury, prior spine surgery, and laminectomy.
Can ankylosing spondylitis cause cervical kyphosis?
Yes. Ankylosing spondylitis causes the vertebrae to fuse together, which can lock the neck spine into an abnormal forward curve.
How does degenerative disc disease cause cervical kyphosis?
The discs between the vertebrae wear down over time, changing how the bones stack together and allowing the curve to reverse.
Can cervical kyphosis be present at birth?
Yes. Spinal abnormalities present at birth can cause the neck to curve abnormally.
Can spine tumors cause cervical kyphosis?
Yes. Tumors in the spine alter bone structure and alignment, potentially pushing the neck into a forward curve.
Can trauma cause cervical kyphosis?
Yes. Trauma or injury to the spine can change how the cervical vertebrae sit and curve.
Can prior spine surgery cause cervical kyphosis?
Yes. Previous operations on the spine can alter the mechanics of the neck and contribute to kyphosis.
What is a laminectomy?
Laminectomy is surgery to relieve pressure on the spinal cord, often to treat spinal stenosis. It removes part of the vertebra called the lamina.
How can laminectomy cause cervical kyphosis?
Removing the lamina changes how the head is supported on the cervical spine. The head's weight shifts forward, and over time that forward pull can progress the kyphotic deformity.
Does cervical kyphosis always cause symptoms?
No. Symptoms depend on the severity of the curve and whether it compresses nerves or the spinal cord.
What are the main symptoms of cervical kyphosis?
Symptoms include decreased range of motion of the head and neck, difficulty swallowing, headache, instability when walking, loss of fine motor function in the hands, muscle weakness in the shoulders, arms or hands, pain in the neck, back, shoulders or arms, poor bladder or bowel control, and tingling or numbness.
What is radiculopathy?
Radiculopathy is the medical term for a pinched nerve. Cervical kyphosis symptoms frequently relate to pinched nerves in the neck.
What is myelopathy?
Myelopathy is compression of the spinal cord. Severe cervical kyphosis can press on the cord and produce symptoms like walking instability and loss of hand control.
Can cervical kyphosis change my gaze?
Yes. The neck curve determines your natural gaze level. In severe cases, the forward curve tilts the gaze permanently downward.
Can cervical kyphosis cause difficulty swallowing?
Yes. Difficulty swallowing (dysphagia) is one of the recognized symptoms of cervical kyphosis.
Can cervical kyphosis affect my hands?
Yes. Loss of fine motor function and muscle weakness in the hands are symptoms of nerve or spinal cord compression from the curve.
Can cervical kyphosis cause bladder problems?
Yes. Poor urinary or fecal control can be a symptom of spinal cord compression (myelopathy), and it's important to seek care if you notice it.
How is cervical kyphosis diagnosed?
Through medical history, symptom review, and a physical exam checking balance, movement, posture, reflexes, and strength, plus imaging with X-ray, MRI, or CT scan.
What does an X-ray show for cervical kyphosis?
An X-ray shows the overall alignment and curve of the cervical spine.
What does an MRI show for cervical kyphosis?
An MRI shows detailed images of the spinal cord, nerves, and soft tissues, revealing any compression.
What does a CT scan show for cervical kyphosis?
A CT scan provides cross-sectional images of the bone for precise structural detail.
How is mild cervical kyphosis treated?
Mild cases are treated without surgery, using medications that reduce pain and inflammation and physical therapy with neck exercises or traction.
Does physical therapy always work for cervical kyphosis?
No. Physical therapy may relieve pain and restore the normal neck curve for many people, but it may not work for everyone.
What is cervical traction?
Traction is a physical therapy technique that gently pulls the head and neck to relieve pressure and pain.
When is surgery recommended for cervical kyphosis?
Surgery is recommended if the kyphosis causes pain or neurological symptoms such as muscle weakness, tingling, or coordination issues.
What determines the type of cervical kyphosis surgery?
The flexibility of the spine. A rigid spine from ankylosing spondylitis requires a different approach than a flexible curve.
What is a posterior approach in cervical kyphosis surgery?
The posterior approach enters through the back of the neck.
What is an anterior approach in cervical kyphosis surgery?
The anterior approach operates near the throat, on the front of the spine.
Can both approaches be used together?
Yes. Complex corrections may combine anterior and posterior approaches.
What hardware is used in cervical kyphosis surgery?
Surgeons may use metal plates, rods, and screws to stabilize the corrected spine.
What are the goals of cervical kyphosis surgery?
To relieve compression of the spinal cord and nerves, restore the shape of the spine, and stabilize the spine.
What does recovery from cervical kyphosis surgery involve?
A hospital stay, rest, and limited movement while the provider tracks recovery closely, often followed by physical therapy.
What are the risks of cervical kyphosis surgery?
Infection, bleeding, blood clots, anesthesia reactions, and the added risk of spinal cord injury.
Can correcting one part of the spine cause problems elsewhere?
Yes. Because the spine runs from head to pelvis, correction in one part may lead to problems in another part.
Do most people do well after cervical kyphosis surgery?
Yes. In general, most children and adults do well with surgery, and realignment plus pain reduction can drastically improve quality of life.
Is cervical kyphosis reversible?
Yes. The forward curve is reversible, through physical therapy in mild cases and surgery in severe cases.
Can you prevent cervical kyphosis?
In many cases it cannot be prevented. But regular physical activity and appropriate exercise help when the cause is ankylosing spondylitis or degenerative disc disease.
Why does exercise help prevent worsening cervical kyphosis?
Regular physical activity reduces pain, increases strength and flexibility, and helps prevent further deterioration of the spine.
Do large pillows affect cervical kyphosis?
Avoiding excessively large pillows can reduce harmful neck flexion when lying on your back during sleep.
When should I seek urgent care for cervical kyphosis?
Call your healthcare provider if you notice changes in your walking, loss of balance or clumsiness, new or worsening neck pain, or numbness, tingling or weakness in your hands or fingers. Loss of bladder or bowel control is also a symptom of spinal cord compression.
