The L5-S1 spinal motion segment, also called the lumbosacral joint, is the transition region between the lumbar spine and sacral spine in the lower back. In this region, the curvature of the spine changes from lumbar lordosis (forward curve) to sacral kyphosis (backward curve).

Conditions affecting the L5-S1 spinal motion segment are usually treated with nonsurgical methods. If the lower back and/or leg symptoms worsen or do not improve despite these treatments, or in case of certain medical emergencies, such as tumors or cauda equina syndrome, surgery may be recommended.

2023年7月24日 · The L5 S1 joint, or the lumbosacral joint, is a critical joint. It lies between the lumbar segment of the spine and the auricular processes of the sacrum. The L5-S1 joint plays a vital role in transmitting the weight of the body via the sacrum and ilium downwards.

2024年12月9日 · The L5-S1 spine plays an essential role in maintaining lower back stability and mobility. Understanding the common conditions that affect this critical segment, as well as the advanced diagnostic and treatment options available, empowers patients to make informed decisions about their care.

2024年9月4日 · The lumbosacral joint, also called L5-S1, is a term used to describe a part of the spine. L5-S1 is the exact spot where the lumbar spine ends and the sacral spine begins. The lumbosacral joint connects these bones.

Common causes of L5-S1 pain include herniated discs, degenerative disc disease, and spinal stenosis. Treatment options range from conservative interventions to surgical procedures. Preventive habits are key to avoiding pain and maintaining a healthy spine.

2023年2月14日 · Also known as your lumbosacral joint, your L5-S1 is the fifth vertebra of your lower back, which sits on top of the first bone in your sacrum. Long story short: Your L5-S1 is a joint in your lower back. As with the other joints in your lumbar spine, your L5-S1 is subject to compression and strain, which can cause some uncomfortable side effects.

2024年5月16日 · L5-S1 is the exact spot where the lumbar spine ends and the sacral spine begins. The lumbosacral joint is the joint that connects these bones. L5-S1 is composed of the last bone in the low back, called L5, and the triangle-shaped bone beneath, known as the sacrum. The sacrum is made of five fused bones, of which the S1 is the topmost.

The L5-S1, also called the lumbosacral joint, is a term used to describe a part of the spine. It is where the lumbar spine ends and the sacral spine begins, and it connects these bones. The lumbosacral joint is also susceptible to misalignment and injury, such as disc herniation or a spinal disorder called spondylolisthesis.

The L5-S1 spinal motion segment, also called the lumbosacral joint, serves as the transition between the lumbar and sacral regions of the spine in the low back. This segment consists of the L5 and S1 vertebrae and the anatomical structures connecting them.
