Mid & Upper Back

What It Is

Rounded shoulders from the side — the front tightens and the upper back is left holding the load.

Hyperkyphosis is a curve in the spine that makes the upper back bend forwards too much, so that it looks hunched or rounded (NHS, 2025). Over the course of time, it can become quite excessive, and it's not uncommon to see it in older people. A worsening curve is linked with poorer physical function and a higher risk of falls (Koelé, Lems and Willems, 2020).

Hyperkyphosis can sometimes be called an "increased kyphosis". One should keep in mind that having a kyphosis is normal: the upper back naturally curves forward, and to not have a kyphosis would be considered abnormal (American Academy of Orthopaedic Surgeons, n.d.).

There Are a Number of Reasons Why It Happens

1. Poor Posture

Postural kyphosis is the most common type of kyphosis. It is usually caused by poor posture or slouching and often affects teenagers (NHS, 2025). The curve is usually smooth and can often be corrected by standing up straight (American Academy of Orthopaedic Surgeons, n.d.).

2. Scheuermann's Disease

Also called Scheuermann's kyphosis, this is a structural problem in which the backs of some of the vertebrae (the bones of the spine) grow faster than the fronts during childhood and the teenage years. This makes the vertebrae wedge-shaped and causes a forward curve in the upper back (NHS, 2025; American Academy of Orthopaedic Surgeons, n.d.). Unlike postural kyphosis, it can't be corrected just by standing up straight (American Academy of Orthopaedic Surgeons, n.d.).

3. Hereditary

Sometimes hyperkyphosis occurs in families, with children developing the "same spine as their parents". Research suggests that inherited factors play a part (Koelé, Lems and Willems, 2020).

4. Weak Back Muscles

An increased kyphosis is linked with weakness of the muscles that straighten the back (Katzman et al., 2010). Staying active and keeping these muscles strong is important.

5. Degenerative Disc Disease

Wear and tear to the discs between the vertebrae can cause them to thin, especially at the front, and this is linked with a greater forward curve in the spine (Katzman et al., 2010).

6. Osteoporosis

Osteoporosis (thinning of the bones) can lead to small fractures of the vertebrae, which can make the spine curve forward more (NHS, 2025; Katzman et al., 2010). However, not everyone with hyperkyphosis has a fracture: studies of older adults have found that only around 40% of those with the most severe curves have spinal fractures (Katzman et al., 2010).

Arthritis and spinal injuries can also cause kyphosis (NHS, 2025).

Hyperkyphosis Anatomy

The spine has a natural inward curve in the neck and lower back, known as a lordosis. The opposite of a lordosis is a kyphosis, which is the natural outward (rounded) curve of the upper back, or thoracic spine (American Academy of Orthopaedic Surgeons, n.d.). A normal upper back curve is about 20 to 45 degrees, and a curve of more than 50 degrees is called hyperkyphosis (American Academy of Orthopaedic Surgeons, n.d.). The ability of the spine to stay in position depends on many parts working together. All of the vertebral bodies in the spine need to be strong enough to adequately support the head and maintain the normal shape of the spine. Ligaments, facet joints and soft tissues in the back and neck have to be strong. The back muscles have to be capable of resisting the effects of gravity that works to pull the head forward. If any damage is sustained to any of these areas, kyphotic deformities can occur.
