Suprascapular nerve entrapment (SNE) surgery effectively relieved pain and improved shoulder muscle function in most patients. Surgical decompression is recommended for SNE when conservative treatments fail or muscle atrophy is present.

Area of Science:

  • Orthopedics
  • Neurology
  • Sports Medicine

Background:

  • Suprascapular nerve entrapment (SNE) is a rare cause of shoulder pain and radicular discomfort.
  • It often presents subtly and requires consideration in differential diagnoses.
  • Causes include trauma, ganglion cysts, and athletic activities, particularly in volleyball players.

Purpose of the Study:

  • To evaluate the outcomes of surgical decompression for SNE.
  • To assess pain relief and functional recovery after surgery.
  • To determine the efficacy of the posterior surgical approach.

Main Methods:

  • Surgical decompression of the suprascapular nerve was performed on 28 cases in 27 patients over 10 years.
  • Patients were evaluated for pain, paresis, muscle atrophy, and sensory deficits.

  • Electromyography was used for diagnosis, with a mean follow-up of 20.8 months.

    • Main Results:

    • 16 of 19 patients with preoperative pain were pain-free post-surgery; 3 reported improvement.
    • Motor function improved in 86.7% of the supraspinatus and 70.8% of the infraspinatus muscles.
    • Muscle atrophy resolved in 80.7% of the supraspinatus and 50% of the infraspinatus muscles.

    Conclusions:

    • Surgical treatment for SNE is indicated for persistent pain after conservative management and in cases with muscle atrophy.
    • The posterior surgical approach is recommended for its minimal risks and good outcomes.
    • Surgical decompression offers significant pain relief and functional restoration for SNE patients.
