Herniated Intervertebral Disc l: Introduction

Herniated 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...

Degenerative Disc Disease I: Introduction

Degenerative Disc Disease I: Introduction

Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...

Degenerative Disc Disease ll: Pathophysiology

Degenerative Disc Disease ll: Pathophysiology

The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...

Summary

Degenerative lumbar spinal stenosis is a common cause of back pain in older adults. Conservative treatments are often effective, but surgical options like decompression and fusion may be necessary for severe cases.

Background:

Degenerative lumbar spinal stenosis (DLSS) is a primary cause of low back pain and sciatica in the elderly.
Accurate diagnosis relies on correlating clinical presentation with advanced imaging, particularly MRI.

Purpose of the Study:

To review current literature on DLSS, covering epidemiology, pathophysiology, clinical features, and diagnostic approaches.
To emphasize the importance of precise pain localization and differential diagnosis before treatment.

Main Methods:

Comprehensive bibliographic investigation of current scientific literature.
Analysis of clinical manifestations, diagnostic imaging (MRI), and treatment outcomes.

Main Results:

Conservative management (medication, physical therapy) is effective for most DLSS cases.
Injections (epidural, foraminal, facetary) can alleviate sciatica but are less effective for neurological claudication.
Surgical decompression, with or without fusion, is the gold standard for severe or unstable cases, often requiring correction of spinal axis deviations.

Conclusions:

Accurate diagnosis and tailored treatment are crucial for managing DLSS.
A stepwise approach, from conservative care to targeted injections and surgical intervention, optimizes patient outcomes.
Surgical correction of spinal instability and sagittal alignment is vital in complex DLSS cases.
