Spinal Nerves: Plexus I

Spinal Nerves: Plexus I

Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
The Cervical Plexus
The cervical plexus, formed by the anterior rami of the first four...

Summary

Cervical spinal surgery can lead to C5 nerve root palsy, a rare complication. Combined anterior-posterior surgical approaches in older males with myelopathy showed the highest risk for this condition.

Area of Science:

Neurosurgery
Spinal Surgery
Neurology

Background:

Cervical spinal surgery is generally safe and effective.
C5 nerve root palsy is a rare complication, characterized by deltoid and biceps weakness.
This palsy is linked to nerve root traction or spinal cord ischemia.

Purpose of the Study:

To investigate the clinical and epidemiological features of C5 palsy.
To identify if specific surgical approaches are associated with a higher incidence of C5 palsy.

Main Methods:

A retrospective analysis of 124 patients undergoing cervical spine surgery over 8 years.
Data collected included demographics, diagnosis, surgical approach, and complications.
Emphasis was placed on identifying cases of C5 nerve root palsy.

Main Results:

Seven patients (5.6%) developed C5 palsy post-surgery.
All affected patients were older males with myelopathy.
C5 palsy occurred only in patients who underwent combined anterior-posterior or posterior approaches, not anterior-only approaches.

Conclusions:

The incidence of C5 nerve root palsy in this cohort was 5.6%.
Combined anterior-posterior surgical approaches in older myelopathic males present the highest risk for C5 palsy.
