Summary
This study found no age or sex differences in lumbar disk radicular conflicts. The most common types were dorsomedial and dorsolateral protrusions, often at the L5-S1 and L4-L5 levels.
Area of Science:
- Orthopedics
- Neurology
- Radiology
Background:
- Disk radicular conflicts are a common cause of low back pain.
- Understanding the incidence and types of these conflicts is crucial for diagnosis and treatment.
Purpose of the Study:
- To determine the incidence of specific types of lumbar disk radicular conflicts.
- To analyze demographic factors associated with these conditions.
Main Methods:
- Retrospective analysis of patient data.
- Categorization of disk protrusion types (dorsomedial, dorsolateral, foraminal).
- Statistical analysis of incidence by spinal level, age, and sex.
Main Results:
- No significant differences in incidence based on patient age or sex.
- Most frequent levels for disk radicular conflicts were L5-S1 and L4-L5.
- Dorsomedial protrusion was the most common type, followed by dorsolateral; foraminal protrusion was least common.
Conclusions:
- Lumbar disk radicular conflicts show no age or sex predilection.
- Specific protrusion types and spinal levels are more prevalent.
- Findings aid in understanding the epidemiology of lumbar radicular pain.

01:29Herniated Intervertebral Disc l: Introduction
Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...
01:10Computed Tomography
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
