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).

Lumbar facet joint disorders most commonly cause lower back pain that is characterized by a localized ache with some degree of stiffness. This pain is usually worse in the morning or after periods of inactivity.

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.

2024年12月9日 · The facet joints in the L5-S1 spine can develop arthritis or inflammation, leading to localized pain and stiffness. This condition is particularly common in individuals with a history of repetitive stress or injury.

2024年9月4日 · The lumbosacral joint (L5-S1) connects the lumbar spine and sacral spine. Learn more about its anatomy, function, and potential issues.

2023年8月4日 · The lumbar facet joint constitutes approximately 15 to 45% of low back pain, with degenerative osteoarthritis as the most common form of facet joint pain. History and physical exam may serve useful in the diagnosis of facet joint syndrome, while imaging with radiographs, CT, and MRI are commonly used yet do not show an effective correlation ...

L4-L5 and L5-S1 facet joints can refer pain extending into the distal lateral leg, and in rare instances to the foot [7] Additionally, facet joint syndrome is more common in the elderly since changes at the joints develop with aging.

The L4-L5 facet joint is the most frequent site of FJC in the lumbar spine because it displays the greatest amount of anteroposterior translation, followed by L5-S1 or L3-L4 and the L2-L3 level. It is more frequent in female patients in their mid-sixties.

2022年11月2日 · The most common site of facet joint pain in the lumbar spine is at the L4-L5 level followed by L5-S1. Some researchers estimate that facet joint syndrome accounts anywhere from 15% of...

Sakuma et al 10 believed that the rat L5-S1 facet joint is multi-segmental, innervated from the L1 to S1 dorsal root ganglia. Kaplan et al 11 demonstrated that 11% of individuals who received medial branch block (MBB) would continue to experience pain from LFJ capsular distension in an experiment, which suggested aberrant innervation.
