A small degree of lordosis is normal. Too much curving is called swayback. Causes Lordosis tends to make the buttocks appear more prominent. Children with hyperlordosis will have a large space underneath the lower back when lying face up on a hard surface.Some children have marked lordosis, but, most often fixes itself as the child grows. This is called benign juvenile lordosis.Spondylolisthesis may cause lordosis. In this condition, a bone (vertebra) in the spine slips out of the proper position onto the bone below it. You may be born with this. It can develop after certain sports activities, such as gymnastics. It may develop along with arthritis in the spine.SpondylolisthesisSpondylolisthesis is a condition in which a bone (vertebra) in the spine moves forward out of the proper position onto the bone below it.Read Article Now Book Mark Article Much less common causes in children include:Achondroplasia, a disorder of bone growth that causes the most common type of dwarfism AchondroplasiaAchondroplasia is a disorder of bone growth that causes the most common type of dwarfism.Read Article Now Book Mark Article Muscular dystrophy Muscular dystrophyMuscular dystrophy is a group of inherited disorders that cause muscle weakness and loss of muscle tissue, which get worse over time.ImageRead Article Now Book Mark Article Other genetic conditions Home Care Most of the time, lordosis is not treated if the back is flexible. It is not likely to progress or cause problems. When to Contact a Medical Professional Contact your health care provider if you notice that your child has an exaggerated posture or a curve in the back. Your provider must check to see if there is a medical problem. What to Expect at Your Office Visit The provider will do a physical exam. To examine the spine, your child may have to bend forward, to the side, and to lie flat on a table. If the lordotic curve is flexible (when the child bends forward the curve reverses itself), it is generally not a concern. If the curve does not move, medical evaluation and treatment are needed.Other tests may be needed, particularly if the curve seems "fixed" (not bendable).

The thoracic vertebrae comprise the chest section and have ribs attached. The lumbar vertebrae are the remaining vertebrae below the last thoracic bone and the top of the sacrum. The sacral vertebrae are caged within the bones of the pelvis, and the coccyx represents the terminal vertebrae or vestigial tail.Skeletal spineillustrationLordosis - illustration Lordosis is excessive curvature in the lumbar portion of the spine, which gives a swayback appearance.LordosisillustrationSkeletal spine - illustration The spine is divided into several sections.
