Suprascapular entrapment neuropathy

Area of Science:

• Orthopedic Surgery
• Neurology
• Anatomy

Background:

• Suprascapular nerve entrapment neuropathy is a condition affecting the shoulder.
• It occurs when the suprascapular nerve is compressed as it passes beneath the transverse scapular ligament.
• Understanding the anatomical variations is crucial for diagnosis and treatment.

Purpose of the Study:

• To describe the syndrome of suprascapular nerve entrapment neuropathy.
• To discuss the relevant anatomy and comparative anatomy.
• To present case histories and treatment outcomes.

Main Methods:

• Review of anatomical structures involved in suprascapular nerve entrapment.
• Analysis of five clinical case histories.
• Electromyogram (EMG) findings in affected patients.

Main Results:

• Cardinal findings include shoulder pain, weakness, and atrophy of the spinati muscles.
• Positive electromyogram results confirmed nerve damage.
• Surgical division of the transverse scapular ligament was the primary treatment.

Conclusions:

• Suprascapular nerve entrapment neuropathy is characterized by specific clinical and electrodiagnostic findings.
• Anatomical knowledge, particularly of the transverse scapular ligament, is key.
• Division of the transverse scapular ligament offers an effective treatment for this condition.
