5 Easy Facts About Lumbar Spine Injury L1-L5 - Spinal Cord Shown

Five back spinal nerve roots are discovered on each side. This Website and strong laminae are the plates that extend posteromedially from the pedicle. The oval shaped spinous procedures are directed posteriorly from the union of the laminae. The 2 exceptional (directed posteromedially) and inferior (directed anterolaterally) articular processes, identified SAP and IAP, respectively, extend cranially and caudally from the point where the pedicles and laminae join.

When viewed in an oblique projection, the overview of the elements and the pars interarticularis look like the neck of a Scottie pet (see the image below). Drawing of 2 lumbar segments viewed from an oblique angle. The summary of the elements and the pars interarticularis has the look of the "neck" of a Scottie dog.

They have an upper tubercle at the junction with the exceptional articular process (mammillary process) and an inferior tubercle at the base of the process (accessory procedure). These bony protuberances are websites of accessories of deep back muscles. The back spine has an anterior, middle, and posterior column that is relevant for back spinal column fractures (see the following images).

Lumbar vertebrae are defined by massive bodies and robust spinous and transverse processes. Their articular facets are oriented rather parasagittally, which is believed to contribute the big variety of anteroposterior bending possible in between back vertebrae. Back vertebrae also consist of little mammillary and accessory processes on their bodies. These bony protuberances are sites of accessory of deep lumbosacral muscles.

The synovial joints in between the superior and inferior articular processes on nearby vertebrae are called the aspect joints (also called zygapophysial joints or Z-joints). They allow basic moving motions. The motion of the lumbar spine is mostly restricted to flexion and extension with a minor degree of rotation (see the image below).

A spondylolysis takes place if ossification of the pars interarticularis fails to occur. The 3-joint complex is formed between 2 lumbar vertebrae. Joint 1: Disc between 2 vertebral bodies; Joint 2: Left element (zygapophyseal) joint; Joint 3: Right facet (zygapophyseal) joint. Lumbar Intervertebral Discs Discs form the primary connection in between vertebrae.
