In this protocol, two approaches are described to make uniaxial compression testing of mouse lumbar vertebrae more attainable. First, the conversion of a three-point bending machine to a compression testing machine is described. Second, an embedding method for preparing the loading surface that uses bone cement is adapted for mouse lumbar vertebrae.

This video describes the technique of intrathecal placement of a lumbar drain in a porcine ischemic model, which helps in draining the cerebrospinal fluid to a drainage system. The cerebrospinal fluid pressure is monitored by the drainage system, and fluid is drained to maintain a constant cerebrospinal fluid pressure.

General Structure of a Vertebra

A typical vertebra, with the exception of the sacrum and coccyx, consists of a body, a vertebral arch, and seven different projections termed processes. The anterior portion of the vertebrae, the body, supports about half the body’s weight. The vertebral bodies progressively increase in size and thickness from the cervical region to the lumbar region of the vertebral column. The intervertebral discs present between the bodies of adjacent vertebrae firmly unites them, forming a continuous column.
FAQs
Their broad vertebral bodies and robust arches distribute compressive forces generated by the body's weight. This arrangement is especially important in the lower back, where the mobile vertebral column must support substantial loading while still allowing movement. Studying these structures helps explain lumbar biomechanics and how mechanical demands relate to spinal function.
These structures coordinate controlled motion rather than unrestricted movement. Intervertebral discs and facet joints permit flexion and extension, while allowing only limited rotation in the lumbar region. Their contribution helps researchers relate lumbar anatomy to movement patterns and investigate how altered structures may be associated with conditions such as disc degeneration or low-back pain.
The lumbar curve helps the body maintain posture and balance while the lower back supports the weight-bearing demands of the vertebral column. Considering the curve alongside the vertebrae, discs, and facet joints gives biology researchers a more complete view of how spinal shape and mobility work together during normal movement.
They are examined when researchers or clinicians investigate low-back pain, disc degeneration, vertebral fractures, or developmental abnormalities. Examining the lumbar vertebrae in these contexts connects structural anatomy with biomechanics, movement, and nerve protection. This makes the region relevant to biological research, clinical assessment, and understanding how disease or abnormal development may affect spinal function.
Clinical imaging supports examination of lumbar vertebrae in contexts such as low-back pain, disc degeneration, vertebral fractures, and developmental abnormalities. Because the region combines load-bearing structures with joints and discs, imaging findings can contribute to biological and clinical assessment, while also supporting investigation and surgical planning.
Lumbar anatomy is central to surgical planning because the vertebrae, intervertebral discs, facet joints, lumbar curve, and protected nerves together shape spinal structure and movement. Understanding their relationships helps place clinical problems, including fractures, disc degeneration, and developmental abnormalities, within the broader biomechanics of the lower back.
