Summary

Surgical treatment for sciatica due to vertebral disk pathologies effectively addresses nerve root compression, particularly in the L5 and L4 spinal segments. Findings confirm surgical intervention is crucial for many patients with this condition.

Area of Science:

Neurosurgery
Orthopedic Surgery
Spinal Disorders

Background:

Sciatica, often caused by vertebral disk pathologies, leads to nerve root compression.
Surgical intervention is a common treatment for severe sciatica.
Understanding the patterns of nerve root involvement is critical for surgical planning.

Purpose of the Study:

To analyze surgical outcomes for sciatica patients with vertebral disk pathologies.
To identify the most affected spinal nerve roots in sciatica cases.
To evaluate the diagnostic accuracy of radiculography in identifying disk prolapse.

Main Methods:

Retrospective analysis of 187 patients undergoing surgery for sciatica.
Documentation of nerve root compression laterality and spinal level.

Related Experiment Videos

Intra-operative confirmation of radiculography findings.

Main Results:

All 187 patients exhibited nerve root compression (54% left, 43% right, 3% bilateral).
L5 (51%) and L4 (36%) spinal segments were most commonly affected.
87% of abnormal radiculographies were intra-operatively confirmed; 11 cases showed disk disease despite normal radiculography, likely due to extreme lateral prolapse.

Conclusions:

Surgical treatment is effective for sciatica stemming from vertebral disk issues.
Nerve root compression at L5 and L4 levels is prevalent.
Radiculography may not detect all disk pathologies, necessitating clinical correlation for surgical decisions.
