Adult kyphosis can have varying symptoms and degrees of severity, from minor changes in the shape of your back, to severe deformity, nerve problems, and chronic pain. Kyphosis is most common in the thoracic spine, though it can also affect the cervical and lumbar spine.
What vertebrae is affected from kyphosis and lordosis?
Kyphosis (also called hyperkyphosis or dowager’s hump) describes an abnormal curvature of the upper back that causes a rounded or hunched back. Lordosis (also called swayback) describes an abnormal inward curvature of the lower back (lumbar spine, just above the buttocks).
Which area of the spine does lordosis affect?
The spine normally curves at the neck, the torso and the lower back area. When the spine curves too far inward, the condition is called lordosis or swayback. Lordosis can cause pain that sometimes affects the ability to move. It is usually found in the lower back.
What region causes lordosis?
Similarly, kyphosis historically refers to abnormal convex curvature of the spine. The normal outward (convex) curvature in the thoracic and sacral regions is also termed kyphosis or kyphotic. The term comes from the Greek lordōsis, from lordos (“bent backward”)….

What affects lordosis?
But if your curve arches too far inward, it’s called lordosis, or swayback. Lordosis can affect your lower back and neck. This can lead to excess pressure on the spine, causing pain and discomfort. It can affect your ability to move if it’s severe and left untreated.
What muscles are affected by kyphosis?
Kyphosis increases tension in the shoulder muscles, including the pectoralis major, subclavius, and pectoralis minor, and the shoulders show excessive internal rotation. Also, the rotator cuff muscles responsible for stability are weakened1, 2).
What part of the spine does kyphosis affect?
The lumbar spine has a lordotic curve (outward curve). Kyphosis can affect the lumbar spine, especially in a region called the thoracolumbar region—the area where the thoracic and lumbar regions come together.
What is loss of lordosis?
Abnormal spine curvature does not follow the normal spine curves and results in a loss of the body’s alignment and center of gravity. Loss of lordosis is the flattening of the normal spinal lordosis in either the lumbar or cervical spine.
What is the lumbar region?
The lumbar region of the spine, more commonly known as the lower back, consists of five vertebrae labeled L1 through L5. The lumbar region is situated between the thoracic, or chest, region of the spine, and the sacrum. These muscles can spasm or become strained, which is a common cause of lower back pain.
Which vertebrae are affected by lordosis?
Lordosis is found in all age groups. It primarily affects the lumbar spine, but can occur in the neck (cervical). When found in the lumbar spine, the patient may appear swayback, with the buttocks more prominent, and in general an exaggerated posture. Lumbar lordosis can be painful, too, sometimes affecting movement.
What is the difference between lordosis and kyphosis?
The terms ‘lordosis’ and ‘kyphosis’ refer to the spine’s natural curves, and when these curves fall beyond a normal range, the conditions are also called ‘lordosis’ and ‘kyphosis’. Normal lordotic curves are found in the neck (cervical spine) and the lower back (lumbar spine). Lordotic curves bend forwards, towards the body’s center.
Can kyphosis cause pain in the lower back?
Pain can also be felt in the lower back if the kyphosis of the upper spine causes a counteractive curvature in the lumbar spine. With congenital kyphosis, patients are born with the condition as it develops in utero. This form develops due to a malformation in the spinal column.
How many lordotic and kyphotic curves are in the human spine?
In the human spine, there are two lordotic curves (lordosis): one in the neck (cervical) and the other in the lower back (lumbar). But there is only one kyphotic curve located in the upper and mid-back (thoracic spine).
Is it normal to have lordosis in thoracic region?
Similarly, lordotic curves should never be seen in the thoracic region of the spine. Additionally, the lordotic or kyphotic of the spine are considered normal when they present within acceptable limits. As mentioned earlier, lordosis and kyphosis are references to spinal curves.
