Spinal deformity is an abnormal alignment or curve of the bony vertebral column. Adult scoliosis and kyphosis can be caused by age-related wear and tear on the back or complications from past surgeries.
What are the abnormal spinal curves?
Abnormal curvature in the spine can put it out of alignment. Abnormal curvature seen from the side is called sagittal imbalance. Types of sagittal imbalance include kyphosis, flatback syndrome, and chin-on-chest syndrome. Abnormal curvature of the spine seen from the back is called scoliosis.
Can a curved spine be corrected?
In moderate to severe cases, scoliosis may be corrected through bracing and/or surgery. If you suspect scoliosis, you should consult your doctor about an appropriate treatment plan.
What is a normal spine look like?
The normal spine has an S-shaped curve when viewed from the side. This shape allows for an even distribution of weight and flexibility of movement. The spine curves in the following ways: The cervical spine curves slightly inward, sometimes described as a backward C-shape or lordotic curve.
How much curve in spine is normal?
Front and side views of the body show normal alignment of the spine bones and the natural curves. When viewed from the front the spine is perfectly straight, but from the side it has three curves (Fig. 1). This curvature absorbs the shock of footsteps and positions our head naturally over the pelvis and hip.
What are the primary spinal curves?
In a normal spine there are four types of spinal curvatures important to balance, flexibility, and stress absorption and distribution.
|Type of Spinal Curves||Curve Description|
|Cervical Lordosis||20 to 40 degrees|
|Thoracic Kyphosis||20 to 40 degrees|
|Lumbar Lordosis||40 to 60 degrees|
Is it normal to have a curved spine?
In normal, healthy individuals, the spine always curves. However, it occurs in a very specific way. SpineUniverse explains that this curve is normally only visible when viewed from a side (aka lateral) view.
Is your spine meant to be straight?
It may not be what your mother told you, but the spine is not meant to be straight. Because of its position, the spine has to take pressure, weight, and force from structures that, by comparison, tend to be heavier and bulkier. An example is your pelvis, which is a large bone into which the spine wedges.
What degree is a normal spine?
Anything less than 10 degrees is considered normal variation in a normal individual. The curvature takes place in three dimensions. Normally, the spine is straight when looking at a person from the front or back. When looking at a person from the side, the spine is curved.
Which spinal nerves affect which parts of the body?
The nerves of the cervical spine go to the upper chest and arms. The nerves in your thoracic spine go to your chest and abdomen. The nerves of the lumbar spine then reach to your legs, bowel, and bladder. These nerves coordinate and control all the body’s organs and parts, and let you control your muscles.
What are two functional reasons for the natural curves of the human spine?
First and foremost, proper curvature of the spine gives it flexibility and creates support. The offsetting curves of each section create a spring-like structure, enabling the spine to act as a natural shock-absorber.
