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). L5-S1 helps transfer loads from the spine into the pelvis and legs.

Understanding anatomy and function of the L5-S1 spinal segment is essential for detecting potential issues. Common causes of L5-S1 pain include herniated discs, degenerative disc disease, and spinal stenosis. Treatment options range from …
