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...

Area of Science:

Orthopedic Surgery
Neuroscience
Sports Medicine

Background:

Suprascapular nerve (SSN) entrapment is an uncommon yet significant cause of posterior shoulder pain and infraspinatus muscle dysfunction.
Compression, typically at the spinoglenoid notch, results in characteristic weakness and atrophy of the infraspinatus.
Accurate diagnosis relies on thorough patient history, physical examination, and targeted investigations.

Purpose of the Study:

To describe a specific surgical technique for open decompression of the suprascapular nerve at the spinoglenoid notch.
To provide a reliable and effective method for addressing SSN entrapment refractory to conservative treatments.

Main Methods:

This technical note outlines an open surgical approach for SSN decompression.
The technique emphasizes direct visualization of the suprascapular nerve within the spinoglenoid notch.
The procedure aims for safe and comprehensive decompression of the entrapped nerve.

Main Results:

The described open technique allows for direct visualization of the SSN.
This approach facilitates a safe, reliable, and thorough decompression of the nerve at the spinoglenoid notch.

Conclusions:

Open surgical decompression at the spinoglenoid notch is an effective treatment for suprascapular nerve entrapment.
This technique provides direct visualization and ensures complete nerve release, addressing posterior shoulder pain and weakness.
