Frozen shoulder, or adhesive capsulitis, is more than just a stiff joint. It’s a complex inflammatory condition driven by a process called neovascularization—the formation of abnormal new blood vessels. These vessels create a vicious cycle of inflammation and pain that conventional treatments simply can’t break.
“The underlying pathology of Adhesive Capsulitis is the combination of synovial inflammation and capsular fibrosis.” - Liang et al. [1]
While your doctor may have explained that your joint capsule is inflamed and thickened, they may not have discussed the critical role these abnormal blood vessels play in perpetuating your pain. This is the missing piece of the puzzle that explains why your previous treatments have failed to provide lasting relief.
Shoulder joint embolization is a non-surgical procedure performed by an interventional radiologist. Here’s how it works:
1. Mapping the Abnormal Vessels: Using advanced imaging, the interventional radiologist identifies the specific abnormal blood vessels that are feeding the inflammation in your shoulder.
2. Blocking the Blood Flow: Tiny, microscopic particles are injected into these abnormal vessels, blocking the blood flow that fuels the inflammation.
*(This does not disrupt blood flow to the normal healthy tissue)
3. Breaking the Cycle of Pain: By restricting blood flow to the inflamed tissue, the procedure breaks the cycle of inflammation and pain, allowing your shoulder to heal naturally.
The Evidence: Real Results for Patients Like You
The clinical evidence for shoulder joint embolization is compelling. Studies have shown that patients who undergo this procedure experience:
• Significant Pain Reduction: Patients report a dramatic decrease in pain within weeks of the procedure.
• Improved Range of Motion: With the inflammation resolved, patients regain mobility and function in their shoulder.
• Lasting Relief: Because the procedure addresses the root cause of the pain, the results are long-lasting.
In a recent study, patients who underwent shoulder joint embolization experienced significant reductions in pain and improvements in function at 1, 3, and 6 months after the procedure [1].
Shaded areas around vessels are called "hyperemia" and are the abnormal growth of micro blood vessels causing pain and inflammation.
After embolization, the excessive hypervascularization "disappears" improving pain and function by eliminating the source of the inflammation.
