Summary
This study measured lumbar nerve root dimensions and angles in cadavers. Findings provide crucial morphometric data for understanding lumbar pathologies and improving surgical outcomes.
Area of Science:
- Anatomy
- Orthopedics
- Neurosurgery
Background:
- Lumbar nerve root anatomy is critical for understanding spinal pathologies.
- Detailed morphometric data aids in diagnosing and treating conditions affecting the lumbar spine.
Purpose of the Study:
- To perform a detailed morphometric analysis of lumbar nerve roots and adjacent structures.
- To quantify lumbar root diameters, root-dura exit angles, and lumbar pedicle dimensions.
Main Methods:
- Dissection and morphometric analysis of lumbar nerve roots in 14 human cadavers (70 lumbar vertebrae).
- Measurement of lumbar root diameters, root-dura exit angles, and lumbar pedicle dimensions at each vertebral level.
Main Results:
- Lumbar root diameters ranged from 3.5 mm (L1) to 5.6 mm (L5).
- Root-dura exit angles varied from 16.3° (L5) to 26.2° (L1).
- Lumbar pedicle dimensions showed significant variation, with widths from 8.4 mm (L1) to 17.1 mm (L5) and lengths from 13.8 mm (L4) to 15.3 mm (L2).
Conclusions:
- Quantitative morphometric data of lumbar nerve roots and pedicles enhance understanding of spinal pathologies.
- These anatomical insights can potentially improve the success rates of surgical interventions in the lumbar region.

01:30General 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.
01:16Vertebral Column: Regions and Curvature
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form the...

01:15Spinal Cord: Gross Anatomy
The spinal cord resides within the protective confines of the vertebral column. It is the main pathway for information traveling between the brain and the body. It plays a fundamental role in nearly all bodily functions, from simple reflexes to complex motor movements. The spinal cord begins at the medulla oblongata at the base of the brainstem and extends downward, terminating at the conus medullaris near the first and second lumbar vertebrae. The spinal cord's length in adults is...
01:16Spinal Cord: Cross-sectional Anatomy
The cross-sectional anatomy of the spinal cord offers a detailed view of its complex structure and function within the central nervous system. At the core of the spinal cord lies the gray matter, characterized by its butterfly or "H"-shaped appearance in cross-section. This central region is enveloped by white matter, with the overall structure divided into symmetrical halves by the dorsal median sulcus and the ventral median fissure.

01:54The Spinal Cord
The spinal cord is the body’s major nerve tract of the central nervous system, communicating afferent sensory information from the periphery to the brain and efferent motor information from the brain to the body. The human spinal cord extends from the hole at the base of the skull, or foramen magnum, to the level of the first or second lumbar vertebra.
01:21Spinal Nerves: Plexus II
The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...
