Lordosis
(Swayback; Saddle Back)
Definition
Lordosis is a curving of the lower back. A certain degree of normal lordosis occurs in the lumbar and cervical spine. This topic refers to abnormal lordosis of the lumbar spine. People with lordosis look like they are arching their lower back and sticking their buttocks out. It can occur in people of all ages.
Excess Lordosis
The sooner lordosis is treated, the better the outcome. If you suspect you have this condition, contact your doctor.
Causes
The exact cause of lordosis is often unknown.
Risk Factors
These factors increase your chance of developing lordosis:
- 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 palsy
- Back surgery
- Hip disorders
- Kyphosis
- Osteoporosis
- Disc problems
- Obesity
Symptoms
Often times there are no symptoms with lordosis. Depending on the degree of abnormal curving, you may experience back pain.
Diagnosis
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 your back and move your back. You may also be asked to see a specialist in spine disorders.
Your doctor may need images of your spine. This can be done with an X-ray, MRI, or CT scan.
Treatment
For mild cases of lordosis, treatment is often not necessary. Talk with your doctor about the best plan for you. Options include the following:
Physical Therapy
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.
Medicines such as nonsteroidal anti-inflammatory drugs (NSAIDs) may be given for discomfort or to decrease swelling.
Prevention
There are no known guidelines to prevent the development of lordosis.
