Arthroscopic suprascapular nerve decompression at the suprascapular notch

Area of Science:

• Orthopedic Surgery
• Neuroanatomy
• Minimally Invasive Procedures

Background:

• The suprascapular nerve is frequently entrapped at the suprascapular notch, causing pain and functional deficits.
• While open surgery and arthroscopy for other locations exist, arthroscopic decompression at the suprascapular notch is not well-described due to anatomical complexity.

Purpose of the Study:

• To describe a novel arthroscopic technique for decompressing the suprascapular nerve at the suprascapular notch.
• To establish reproducible anatomical landmarks for arthroscopic orientation in this region.

Main Methods:

• Utilized standard anatomical landmarks (acromioclavicular joint, conoid ligament, coracoid process) for orientation.
• Developed a new suprascapular portal combined with an accessory portal for surgical access.
• Employed a 4-mm, 70-degree angled arthroscope and a calibrated probe for dissection and nerve decompression.

Main Results:

• Successfully demonstrated an arthroscopic technique for suprascapular nerve decompression at the suprascapular notch.
• Established a stepwise approach using anatomical landmarks for consistent surgical navigation.

Conclusions:

• This novel arthroscopic technique provides a viable minimally invasive option for suprascapular nerve decompression at the suprascapular notch.
• The described method enhances reproducibility and safety through clear anatomical guidance and specialized portals.
