Relief for Chronic Shoulder Pain
Frozen shoulder, medically known as adhesive capsulitis, causes significant stiffness, pain, and loss of motion in the shoulder joint. When conservative treatments fail to bring lasting relief, Adhesive Capsulitis Embolization (ACE) offers a minimally invasive alternative aimed at reducing inflammation and restoring mobility.
What is Adhesive Capsulitis Embolization?
Adhesive Capsulitis Embolization (ACE) is a cutting-edge, image-guided procedure designed to relieve persistent shoulder pain caused by frozen shoulder. The condition is often marked by a progressive reduction in shoulder mobility, especially in external rotation, along with chronic pain and stiffness.
During the ACE procedure, tiny microspheres are delivered through a catheter into the blood vessels supplying the inflamed shoulder capsule. This reduces abnormal blood flow (neovascularization) and inflammation, which are key contributors to ongoing pain and restricted movement. The result is targeted relief without the need for invasive surgery.
ACE is typically recommended for patients who have been experiencing symptoms for more than six months and have not responded to conservative treatments like physical therapy, NSAIDs, or corticosteroid injections.
When Should You Consider ACE?
You may benefit from Adhesive Capsulitis Embolization if:
- You’ve been diagnosed with frozen shoulder and your symptoms have lasted longer than six months.
- Conservative treatments such as NSAIDs, home exercise programs, and steroid injections have not provided sufficient relief.
- You’re experiencing a significant reduction in both active and passive range of motion.
- Daily activities are limited due to shoulder stiffness and pain.
- Imaging has ruled out other shoulder pathologies.
The Process
- Consultation and Evaluation:
At Richardson Pain Solutions, your physician will begin by thoroughly reviewing your symptoms, medical history, and any previous treatments. A physical examination will be performed to assess your range of motion and pain level. Imaging studies, such as MRI or ultrasound, may be ordered to confirm a diagnosis of adhesive capsulitis (frozen shoulder) and rule out other potential causes of shoulder pain. - Preparation:
On the day of the procedure, the skin over the shoulder is sterilized and a local anesthetic is administered to ensure comfort during the treatment.
- Embolization Treatment:
Using imaging guidance, a catheter is inserted through a small puncture in the groin or wrist and guided to the vessels supplying the shoulder joint. Tiny particles are released to block abnormal blood vessels that contribute to chronic inflammation and pain. The process typically takes about 1–2 hours.
- Post-Procedure:
Following the procedure, patients are monitored for a short time before being discharged the same day. Most patients return to normal activities within a few days and begin noticing symptom improvement within 1–2 weeks.
The Benefits of Adhesive Capsulitis Embolization
- Targeted Pain Relief: By reducing inflammation and abnormal blood flow in the joint capsule, patients often experience significant reduction in pain and stiffness.
- Minimally Invasive: This outpatient procedure requires only a small puncture and avoids the need for surgery or general anesthesia.
- Improved Mobility: Many patients report increased range of motion and functional improvements in daily activities.
- Alternative to Surgery: ACE offers an effective option for those who have not found relief from physical therapy, medications, or steroid injections, and want to avoid surgical intervention.
