Summary
A large ganglion cyst caused left suprascapular nerve palsy in a 39-year-old female. Arthroscopic decompression and SLAP repair resolved symptoms, restoring full shoulder function.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Neuroscience
Background:
- Superior labral anterior to posterior (SLAP) lesions are common shoulder injuries.
- Supraglenoid labral cysts can cause nerve compression.
- Suprascapular nerve palsy presents with shoulder pain and weakness.
Purpose of the Study:
- To report a case of suprascapular nerve palsy due to a supraglenoid labral cyst.
- To describe the diagnostic and treatment approach.
- To evaluate the long-term outcome.
Main Methods:
- A 39-year-old female presented with left shoulder pain and weakness.
- Magnetic resonance imaging (MRI) revealed a SLAP lesion and a large supraglenoid labral cyst compressing the suprascapular nerve.
- Arthroscopic decompression of the cyst and SLAP repair were performed.
Main Results:
- The patient experienced significant left posterior shoulder pain and mild weakness in the supraspinatus and infraspinatus muscles.
- MRI confirmed a SLAP lesion with a large supraglenoid labral cyst causing suprascapular nerve compression.
- Postoperatively, the patient remained asymptomatic with full range of motion and strength at 22 months.
Conclusions:
- Large supraglenoid labral cysts can cause suprascapular nerve palsy.
- Arthroscopic management is effective for treating SLAP lesions and associated cysts.
- Surgical decompression and repair lead to excellent long-term outcomes.
