Kyphosis is a normal rounding curve that is seen in the in the upper back. Hyperkyphosis, or hunchback, occurs when the angle of the outward curve is exaggerated. The sooner hyperkyphosis is treated, the better the outcome.

Three main types of hyperkyphosis and their causes include:
Other causes of hyperkyphosis are unknown.
Factors that may increase your chance of hyperkyphosis include:
Hyperkyphosis may cause:
Most cases can be diagnosed during a physical exam. Some cases are found at school during a scoliosis check. Your doctor will ask about your symptoms and medical history. A physical exam will be done to look for abnormal curve in the spine, rounded shoulders, and a hump on the back. Some tests may be done to rule out or confirm other conditions that may be causing hyperkyphosis.
Your doctor may recommend imaging tests to see the spinal curve and the structures around it. These may include:
Your doctor may need to measure how well you breathe if the curve is severe enough. This can be done with pulmonary function tests.
There are a variety of treatments available for hyperkyphosis, depending on the severity. You may need additional treatment to resolve any underlying conditions that contribute to your hyperkyphosis. Your doctor may refer to you a specialist who treats spinal disorders.
Options include the following:
Your doctor may recommend an observation period to see if the curve progresses, or if there are any changes in your symptoms. This means you may have more follow-up appointments. If you notice any progression, changes, or worsening of symptoms, you should contact your doctor.
Your doctor may refer you to a physical therapist to learn specific exercises. This may include strength work, stretching, and overall conditioning. You may also be taught how to maintain a correct posture. You may be instructed to sleep on a firm mattress.
Nonsteroidal anti-inflammatory drugs (NSAIDs) may be given for pain or discomfort.
Braces are sometimes used. They can help correct hyperkyphosis or reduce discomfort.
Surgery may be used when the curve is severe, progresses, or when other treatment methods fail. The goal of surgery is to correct the exaggeration of the curve. The spine is corrected with a metal rod, hooks, or screws in the back bones. Surgeons also use a bone graft to promote new growth and stability.
Vertebral compression fractures are sometimes treated with special cement. The cement is injected into the affected vertebral bodies to restore shape.
There are no current guidelines to prevent hyperkyphosis.
