Suprascapular Nerve Block

A suprascapular nerve block is a minimally invasive, image-guided procedure used to relieve chronic shoulder pain. The suprascapular nerve arises from the brachial plexus and provides both motor function to key shoulder muscles and sensory input from the shoulder joint. Blocking this nerve can significantly reduce pain in patients with inflammatory, traumatic, or degenerative shoulder conditions.

Suprascapular nerve blocks are commonly used for both diagnostic and therapeutic purposes.

What Is a Suprascapular Nerve Block?

A suprascapular nerve block involves injecting a local anesthetic, often combined with corticosteroid medication, near the suprascapular nerve. The goal is to interrupt pain signals transmitted from the shoulder joint to the brain.

The injection may help:

Conditions Treated

Suprascapular nerve blocks are indicated for:

  • Chronic shoulder pain
  • Rotator cuff disease
  • Adhesive capsulitis (frozen shoulder)
  • Shoulder osteoarthritis
  • Rheumatoid arthritis of the shoulder
  • Seronegative spondyloarthropathies
  • Crystal arthropathies
  • Bursitis
  • Postoperative shoulder pain (e.g., after arthroscopy or acromioplasty)
  • Acute shoulder trauma or fracture
  • Acute anterior shoulder dislocation
  • Cancer-related shoulder pain
  • Complex Regional Pain Syndrome affecting the shoulder
  • Suprascapular nerve entrapment

The block can also serve as a diagnostic tool to confirm suprascapular nerve involvement.

Symptoms That May Indicate Suprascapular Nerve Involvement

Patients may experience:

  • Persistent shoulder pain
  • Pain with overhead motion
  • Weakness in shoulder rotation
  • Limited range of motion
  • Pain radiating to the upper back or arm

How the Procedure Is Performed

A suprascapular nerve block is performed in an outpatient setting and typically takes only a few minutes.

The procedure includes:

  1. Positioning the patient in a seated or comfortable upright position
  2. Cleaning the shoulder blade area with antiseptic solution
  3. Identifying the suprascapular notch under imaging guidance
  4. Inserting a small needle near the suprascapular nerve
  5. Injecting local anesthetic and corticosteroid medication

Frequently Asked Questions

How does a suprascapular nerve block relieve shoulder pain?

The injection delivers local anesthetic and corticosteroid near the suprascapular nerve to block pain signals and reduce inflammation in the shoulder joint.

The procedure typically takes 10 to 20 minutes and is performed in an outpatient setting, often with imaging guidance.

You may experience immediate temporary relief from the anesthetic. Longer-lasting relief usually develops within a few days as the steroid reduces inflammation.

Relief may last several weeks to several months, depending on the severity of the shoulder condition.
