lumbosacral spondylosis definition - Sports Zone
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). The lumbosacral joint (L5-S1) connects the lumbar spine and sacral spine.

The movements occurring in this joint are mostly flexion and extension, and a minimal degree of lateral flexion. Lumbosacral radiculopathy is pain and/or neurologic symptoms radiating in one or more lumbar or sacral dermatomes. It usually results from compression of lumbar nerve roots in the lumbosacral spine. 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. The lumbosacral joint connects the spine to the pelvis, serving as a crucial junction in the human body.
