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...

Vertebral compression fractures (VCFs) are a risk after spine SBRT. Female sex, lumbar lesions, and prior VCFs increase risk. Identifying these factors aids in patient management and surveillance.

Area of Science:

Oncology
Radiation Oncology
Spine Surgery

Background:

Vertebral compression fractures (VCFs) are known complications of spine stereotactic body radiation therapy (SBRT).
Limited data exist on prognostic factors predicting VCF development after SBRT for spinal metastases.

Purpose of the Study:

To evaluate risk factors for VCF development after spine SBRT.
To analyze predictors of VCF type (de novo or progressive) and severity.

Main Methods:

Retrospective analysis of 600 spine SBRT treatments for metastases.
Logistic regression and Fine-Gray subdistribution hazard modeling used to identify predictors.
Exclusion criteria included benign tumors, prior surgery, and <1 month follow-up.

Minimally Invasive Treatment for Thoracolumbar Burst Fracture Using Sagittal Alignment Screws and A Trauma Reduction Device

Minimally Invasive Treatment for Thoracolumbar Burst Fracture Using Sagittal Alignment Screws and A Trauma Reduction Device

Published on: November 8, 2024

Main Results:

10% of patients developed VCFs (5% de novo, 5% progressive) with a median time of 6 months.
Female sex, lumbar lesions, and pre-existing VCFs were associated with any VCF development.
Osteolytic disease and epidural tumor extension predicted de novo VCFs, while pre-existing VCFs predicted progressive VCFs.

Conclusions:

Identified patient subgroups at increased risk for VCFs post-spine SBRT.
Findings can guide surveillance and management strategies for at-risk patients.
Individualized discussions on conservative or stabilization approaches are recommended for high-risk patients.
