Kyphosis: what it is, types, causes, symptoms and treatment

Kyphosis is a curve in the spine that makes the top of your back look hunched or rounded. Treatment may not be needed unless the curve is severe or causing problems. It is often caused by bad posture or a problem with the structure of the spine, and sometimes follows a spinal injury or conditions such as arthritis and osteoporosis.

Key facts

At a glance.

  • What it is

    The NHS describes kyphosis as a curve in the spine that makes the top of your back look hunched or rounded.

  • Main symptom

    A hunched or rounded upper back, sometimes with rounded-looking shoulders. A slight curve may cause no other symptoms.

  • Common causes

    The NHS says it is often caused by bad posture or a problem with the structure of the spine, and can sometimes follow a spinal injury or conditions like arthritis and osteoporosis.

  • Three main types

    The NHS lists postural kyphosis (the most common, often affecting teenagers), Scheuermann's kyphosis and congenital kyphosis (rare).

  • Is treatment always needed?

    No. The NHS says treatment is usually only needed if kyphosis is causing problems, and depends on the cause and how severe the curve is.

  • Exercise

    The NHS says you should be able to exercise with kyphosis, and strengthening core muscles can help. Exercises can reduce back pain and stiffness but will not improve the curve or stop it getting worse.

What is kyphosis?

Every spine has gentle natural curves. In kyphosis the curve at the top of the back is bigger than usual. The NHS says a spine with kyphosis has a bigger curve at the top compared with a spine without kyphosis, which is why the upper back and sometimes the shoulders look rounded.

The NHS notes that treatment may not be needed unless it is severe or causing problems, so a rounded back is not automatically a medical problem.

What causes kyphosis? The three main types

The NHS says kyphosis is often caused by bad posture or a problem with the structure of the spine. It can also sometimes happen after a spinal injury or as a result of conditions like arthritis and osteoporosis. It lists 3 main types.

Main types of kyphosis (NHS)
TypeCauseWho is affected
Postural kyphosisUsually bad postureOften teenagers; the most common type
Scheuermann's kyphosisThe back of the spinal bones (vertebrae) grow quicker than the front, so the vertebrae become wedge-shaped and the spine curvesChildren and teenagers (the NHS mentions braces for children with mild to moderate Scheuermann's kyphosis)
Congenital kyphosisA baby's spine does not develop properly and curves as they growRare; present from birth

What are the symptoms of kyphosis?

The NHS says the main symptom is a hunched or rounded upper back, and sometimes rounded-looking shoulders. If the top part of the spine is only slightly curved you may have no other symptoms.

If the curve is more noticeable or gets worse, it can cause back pain and stiffness. A severe curve can cause more serious problems, such as very bad back pain and difficulty breathing.

How is kyphosis diagnosed?

The NHS says to see a GP if you think you or your child might have kyphosis. A GP may refer you to a specialist (an orthopaedic surgeon) who will do tests. The specialist may examine your back while you are bent forwards to see how severe the curve is and how flexible you are, and may check your arms and legs. You may have an X-ray and an MRI scan to look at the spine in more detail.

How is kyphosis treated?

The NHS says treatment is usually only needed if kyphosis is causing problems. If it is needed, it depends on the cause and how severe the curve is. A child may have regular hospital appointments to check whether the curve is getting worse, and the NHS says it may get worse until they have stopped growing.

  • Paracetamol or anti-inflammatory medicine to ease back pain; check with a GP or pharmacist which type of pain relief is most suitable.

  • Physiotherapy to help improve posture and relieve back pain and stiffness.

  • A brace (a rigid support worn around the torso) to help straighten the spine if a child has mild to moderate Scheuermann's kyphosis. The NHS says a brace should only be worn under the supervision of a specialist such as an orthopaedic surgeon.

  • Surgery to straighten the spine if the curve is severe, getting worse or causing very bad pain. The NHS says spinal surgery is usually only done if the benefits outweigh the risks.

Exercise, posture and living with kyphosis

The NHS says you should be able to exercise with kyphosis, and that strengthening the core muscles, the muscles around your tummy and lower back, can help. It advises speaking to a healthcare professional before starting if you are new to exercise or have not exercised for a while.

If you have physiotherapy you may be given specific exercises to reduce back pain and stiffness. The NHS is clear, though, that they will not improve the curve in your spine or stop it getting worse. The NHS also points to its back pain pilates video workout and the Chartered Society of Physiotherapy's video exercises for back pain.

Kyphosis compared with scoliosis

Kyphosis is sometimes confused with scoliosis, but they are different. The NHS describes scoliosis as the spine twisting and curving to the side, most often starting in children aged 10 to 15, with signs such as a visibly curved spine, uneven shoulders or one shoulder or hip sticking out. Kyphosis is a forward rounding of the upper back.

The NHS says that in around 8 in every 10 cases the cause of scoliosis is unknown, and that scoliosis is not thought to be linked to bad posture, exercise or diet. For kyphosis, by contrast, the most common type is related to posture.

NHS and private pathways in general terms

On the NHS, kyphosis is usually first assessed by a GP, who may refer you to an orthopaedic specialist for examination and imaging. Physiotherapy may be offered through the NHS, and in many areas you can refer yourself to NHS community musculoskeletal services without seeing a GP first.

Private orthopaedic and physiotherapy services are also available on a self-paid or insured basis. If a child needs a brace, the NHS says it should only be worn under the supervision of a specialist.

Frequently asked

Quick, plain-English answers to the questions we hear most.

  • What is kyphosis?

    The NHS describes it as a curve in the spine that makes the top of your back look hunched or rounded. Treatment may not be needed unless it is severe or causing problems.

  • What causes kyphosis?

    The NHS says it is often caused by bad posture or a problem with the structure of the spine. It can also follow a spinal injury or result from conditions such as arthritis and osteoporosis.

  • What are the types of kyphosis?

    The NHS lists three main types: postural kyphosis, which is the most common and often affects teenagers; Scheuermann's kyphosis, where the spinal bones grow unevenly; and congenital kyphosis, which is rare and present from birth.

  • What are the symptoms of kyphosis?

    The main symptom is a hunched or rounded upper back. A slight curve may cause no other symptoms, but a bigger curve can cause back pain and stiffness, and a severe curve can cause very bad pain and difficulty breathing.

  • Can kyphosis be corrected?

    Treatment depends on the type and severity. The NHS lists physiotherapy, pain relief, a brace for children with mild to moderate Scheuermann's kyphosis, and surgery for a severe, worsening or very painful curve.

  • Can exercise fix kyphosis?

    The NHS says you should be able to exercise and that strengthening core muscles can help, but exercises will not improve the curve in your spine or stop it getting worse. They can reduce back pain and stiffness.

  • How is kyphosis diagnosed?

    A GP may refer you to an orthopaedic surgeon who will examine your back while you bend forwards and check your arms and legs. The NHS says you may have an X-ray and an MRI scan.

  • Does kyphosis get worse over time?

    It can. The NHS says a more noticeable curve can cause pain and stiffness, and in children it may get worse until they have stopped growing, so they may have regular appointments to check it.

  • Can kyphosis affect breathing?

    The NHS says a severe curve in the spine can cause more serious problems, including very bad back pain and difficulty breathing. See a GP if you are worried about a curve.

  • Is kyphosis the same as scoliosis?

    No. The NHS describes scoliosis as the spine twisting and curving to the side, while kyphosis is a forward curve that makes the upper back look rounded. The two can need different treatment.
