Lordosis is a normal inward curve in the lower back and neck. Hyperlordosis, or swayback, occurs when the angle of the inward curve is exaggerated. The sooner hyperlordosis is treated, the better the outcome.
The shadowed spine to the left shows ideal lordosis.

The exact cause of hyperlordosis is often unknown.
Factors that may increase your chance of hyperlordosis include: Achondroplasia—a genetic disorder that results in abnormal cartilage growth and dwarfism
Spondylolisthesis—displaced vertebrae of back
Neuromuscular disorders such as muscular dystrophy or cerebral palsyCongenital abnormalities of the spineBack surgeryHip disordersPoor postureAbnormal vertebral bodies—more commonly found in children with hyperlordosisHyperkyphosis—an exaggerated outward curve of the thoracic spineOsteoporosisDisc problemsObesity
Often times there are no symptoms with hyperlordosis. Depending on the degree of abnormal curving, you may experience back pain.
Your doctor will ask about your symptoms and medical history. A physical exam will be done. During the physical, your doctor may ask you to bend and move your back. Hyperlordosis can be seen during the exam. Some tests may be done to rule out or confirm other conditions that may be causing hyperlordosis.
Your doctor may recommend imaging tests to see the spinal curve and the structures around it. These may include: X-rayMRI scanCT scan
For mild cases of hyperlordosis, treatment is often not necessary. 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 refer you to a therapist to learn specific exercises. Exercises may be used to strengthen muscles and increase range of motion. You may also be taught how to maintain a correct posture.
Medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) may be given for discomfort or to decrease swelling.
Braces are sometimes used with children. The brace can make sure the curve doesn’t worsen as they grow.
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.
There are no current guidelines to prevent hyperlordosis.
