Lumbar Spine
- The natural curve of the lumbar spine is called lordosis.
- The spinal cord terminates at the level of the L1 or L2 vertebra.
- The pars interarticularis is the most commonly injured part of the lumbar spine in back injuries.
Lumbar Vertebrae
- The body of lumbar vertebrae is kidney-shaped and has a larger size compared to thoracic vertebrae.
- The laminae are broad and flat, forming the posterior wall of the vertebral foramen.
- The pedicles are stout and directed posteriorly.
- The transverse process is long and slender, and its orientation changes from L1 to L5.
- The mamillary process is a small, rounded projection located at the tip of the transverse process.
- The accessory processes are small, located at the base of the transverse process.
- The pars interarticularis is the region between the superior and inferior articular processes.
- The zygapophyseal joints are demonstrated in a sagittal or near-sagittal plane.
- The intervertebral foramina are oriented in a coronal plane, except for L5-S1, which is oriented in a sagittal plane.
L5 Vertebra
- The L5 vertebra has a unique shape, with a larger body and a more horizontal transverse process compared to other lumbar vertebrae.
Sacrum
- The sacrum is formed by the fusion of five vertebrae and is located at the base of the spine.
- It is shaped like a triangular wedge, with a broad base and a narrow apex.
- The sacrum articulates with the two iliac bones to form the sacroiliac joints.
- The sacral canal is located within the sacrum and transmits the sacral nerve roots.
- The sacral promontory is located at the anterior tip of the sacrum and serves as an attachment point for ligaments.
- The sacral foramina are located on the anterior and posterior surfaces of the sacrum.
- The female sacrum is more acutely curved than the male sacrum.
Coccyx
- The coccyx is composed of 3-5 fused vertebrae and is located at the end of the spine.
- It curves downward and forward, with a projection from the first coccygeal segment that joins the sacral cornua.
- The sacral cornua are located at the posterolateral tip of the sacrum.
