What is kyphosis?
Kyphosis is a condition where the upper back curves forward more than normal, creating a rounded or hunched appearance. It's sometimes called a "hunchback" or "roundback," and it can affect people of all ages, from children to older adults.
A normal spine has gentle curves that help with balance and movement. But when the upper curve becomes too steep—usually more than 50 degrees—it’s considered kyphosis. For some, the curve is mild and doesn’t cause any problems. For others, it can lead to back pain, stiffness or a noticeable change in posture.
Kyphosis can happen for different reasons. It may be caused by poor posture, injuries, weakened bones from osteoporosis or certain medical conditions. In kids and teens, it can also be related to a growth issue called Scheuermann’s disease.
Treatment depends on what’s causing the curve and how severe it is. Some people may just need physical therapy or exercises to improve posture. Others might need a back brace or surgery.
Hyperkyphosis
Hyperkyphosis means the curve in the spine is more severe than normal. It usually shows up in adults over 40 and is often linked to osteoporosis or spine fractures. As bones weaken or collapse, the curve can become more noticeable and may cause back pain, stiffness or trouble standing up straight.
Cervical kyphosis
This type affects the neck. Instead of curving slightly backward like it should, the neck curves forward or becomes too straight. This can cause a stiff, upright posture, sometimes called “military neck.” It may lead to neck pain, limited movement or nerve problems in more serious cases.
Congenital kyphosis
This type is present at birth. It happens when the bones in a baby’s spine don’t form the right way or are fused together. Congenital kyphosis can get worse as the child grows and usually needs to be watched closely by a specialist. In some cases, surgery may be needed early on.
Scheuermann’s kyphosis
This type happens when the bones in the spine grow unevenly during childhood. The front of the bones become wedge-shaped, which causes a more noticeable curve. It’s a structural issue and tends to be more rigid than postural kyphosis. It often shows up in teens and may need physical therapy, a back brace or sometimes surgery.
Postural kyphosis
This is the most common type and is usually caused by poor posture or slouching. It often shows up during the teenage years and is more common in girls than boys. The spine itself is still normal, and the curve usually improves with better posture, stretching and strengthening exercises.
Types of kyphosis
There are different types of kyphosis, and each one has its own cause and treatment. Some types are more common in children and teenagers, while others usually appear later in life. Knowing which type you have can help guide the right care.
When to see a doctor
You should see your doctor if noticeable changes in your or your child’s spine concern you. Sometimes, children and teenagers are referred to a doctor for kyphosis after a scoliosis screening at school. The sooner you or your child gets a diagnosis, the earlier you can start treatment.
Kyphosis symptoms
Kyphosis symptoms can range from mild to more serious, depending on how much the spine is curved and what causes it. Some people may not notice any symptoms at first, especially if the curve develops slowly over time.
Common signs of kyphosis include:
- A rounded or hunched upper back
- Head that leans forward or sits lower than the shoulders
- Back pain or stiffness, especially in the upper or mid-back
- Fatigue after standing or sitting for long periods
- Tightness in the back or hamstrings
- In more severe cases, trouble breathing or nerve problems
Kyphosis causes
Kyphosis can have different causes depending on your age, overall health and how the spine is affected. Some cases are related to posture, while others are caused by changes in the bones of the spine.
Common causes include:
- Poor posture: Slouching over time, especially in teens, can lead to postural kyphosis.
- Spinal development issues: Conditions like Scheuermann’s disease cause the bones in the spine to grow unevenly, leading to a curved back.
- Congenital defects: Some babies are born with spine bones that didn’t form properly, which can cause kyphosis as they grow.
- Osteoporosis: This bone-thinning condition can lead to weak or fractured vertebrae, especially in older adults.
- Spinal injuries: Trauma or fractures in the spine can lead to a more severe forward curve.
- Degenerative diseases: Conditions like arthritis can break down the spine over time and lead to kyphosis.
Kyphosis risk factors
Your risk of getting kyphosis depends on your age and family history. Hyperkyphosis becomes more likely as you get older, while postural and Scheuermann’s kyphosis are more common in teenagers. Congenital kyphosis develops before birth.
Scheuermann’s and congenital kyphosis are structural problems without a clear cause. However, you’re more likely to get postural or hyperkyphosis if you have any of the following:
- Connective tissue disorders: Ehlers-Danlos syndrome and similar disorders affect the connective tissue supporting your bones.
- Family history: Studies suggest some forms of kyphosis are partly caused by your genes.
- Poor posture: Slouching can stretch the muscles and ligaments of the spine in children and adults. Physical inactivity and sitting for long periods can worsen your posture.
- Sex: Females are more likely to have postural kyphosis, while Scheuermann’s kyphosis affects twice as many boys as girls.
Complications
If kyphosis becomes more severe or isn’t treated, it can lead to other health problems over time. Possible complications include:
- Chronic back pain: A more pronounced curve can lead to long-term pain or discomfort
- Breathing problems: In severe cases, the curve can press on the lungs and make it harder to breathe
- Limited movement: Stiffness in the spine can affect posture, flexibility and daily activities
- Nerve issues: In rare cases, the curve can pinch nerves, causing numbness or weakness in the arms or legs
- Changes in appearance: A noticeable hunch or rounded back may affect confidence and self-esteem
Most people with kyphosis don’t develop serious complications, especially with early care. If you notice changes in posture, pain or other symptoms, talk with your doctor to help prevent long-term problems.
How is kyphosis diagnosed
If you or your child shows signs of kyphosis, your doctor will start with a thorough evaluation to understand the cause and severity of the curve. Diagnosing kyphosis involves several steps, including a medical history, physical exam and imaging tests. This helps your healthcare provider choose the best treatment plan for you.
Kyphosis treatment
Treatment for kyphosis depends on the type, cause and how severe the curve is. Many people with mild kyphosis manage their symptoms well with simple steps like exercise and posture correction. For more serious cases, additional treatments may be needed to reduce pain, improve posture and prevent the curve from getting worse.
