What is a lumbosacral orthosis (LSO)?

A lumbosacral orthosis (LSO) is a device used to support part of the body and keep it from moving. An LSO is used on the lowest part of the spine. This area includes the lumbar and sacral spine. An LSO is made to fit from your shoulder blades to your tailbone. Some styles can have parts added to help support your spine at the chest level. An LSO can be made of hard or soft material. Corsets and chairback orthoses are examples of an LSO.

Why may I need an LSO?

You may need an LSO if you have a degenerative disc disease or osteoporosis. An abdominal binder can help support your lower back by putting compression (pressure) on your abdomen. This helps relieve lower back pain. Some abdominal binders can be used by pregnant women to help with lower back pain.

Drugs used to treat this and similar conditions

How do I safely use an LSO?

• Get your LSO fitted by your healthcare provider. It is very important that your LSO is the right size for you and that it fits properly. Your healthcare provider will help you make sure the LSO is the right length and style for you. You may need to get an LSO that is custom fit for your body.
• Wear your LSO as directed. You may need to wear your LSO during certain activities or all the time. For example, you may need to wear it during any activity that could injure your back. Check the fit of the LSO often. If it does not fit properly or moves out of place, it could cause more injury. Your healthcare provider may recommend that you wear a T-shirt under the LSO to protect your skin. Check your skin often for redness, sores, or dry patches.
• Care for your LSO. Inspect your LSO often. Do not wear it if it is damaged or broken. Ask your healthcare provider how to care for and clean your LSO.
• Start to strengthen your lower back as directed. You may need to work with a physical therapist to strengthen your lower back by doing exercises. Ask how much physical activity is safe for you.
