Compression of the suprascapular nerve can be caused by which of the following?

• A. Tumors or ganglion cysts
• B. Thickened or calcified suprascapular ligament
• C. Congenital structural changes of the scapula
• D. All of the above

Answer: (D)

Compression of the suprascapular nerve occurs where it passes through the suprascapular notch or spinoglenoid notch, and anything that narrows that space can press on the nerve. Tumors or ganglion cysts can occupy that area and physically impinge on the nerve. The suprascapular ligament can become thickened or calcified, reducing the available space for the nerve to pass. Congenital structural changes of the scapula can alter the notch anatomy and similarly narrow the corridor the nerve travels through. Because all of these scenarios can constrict the same nerve pathway, they are all potential causes of compression.
