If you have been living with a stiff, painful shoulder that refuses to budge no matter how much you stretch, you are not alone. Adhesive capsulitis, commonly known as frozen shoulder, affects an estimated 2 to 5 percent of the general population and can make everyday tasks like reaching for a seatbelt or buttoning a shirt feel nearly impossible.
For years, patients in Queens and across New York had limited options: physical therapy, cortisone injections, or in severe cases, surgery. Now, a newer approach called adhesive capsulitis embolization is offering a minimally invasive alternative that targets the root cause of inflammation rather than just managing symptoms.
At M&S Vascular and Orthopedic Group P.C. in Forest Hills, our team works together to determine whether this procedure is right for you. Here is what you need to know before you consider it.
What Is Adhesive Capsulitis, and Why Does It Happen?
Adhesive capsulitis occurs when the connective tissue surrounding your shoulder joint (the joint capsule) becomes thickened, inflamed, and tight. This restricts the joint's range of motion and causes pain, particularly with movement.
The condition typically progresses through three stages: freezing (pain begins and stiffness develops), frozen (pain may decrease but stiffness peaks), and thawing (motion gradually returns). The full cycle can last anywhere from one to three years without treatment.
While the exact cause remains unclear, researchers have identified that abnormal new blood vessels (neovascularization) form within the inflamed capsule. These vessels sustain the inflammatory process and contribute to both pain and fibrosis. This discovery is what makes embolization a logical treatment target.
How Does Embolization Work for Frozen Shoulder?
Adhesive capsulitis embolization is a minimally invasive procedure performed by an interventional radiologist. The goal is to block the abnormal blood vessels that feed inflammation in the shoulder capsule, essentially cutting off the blood supply that sustains the inflammatory cycle.
Dr. Amir Salem, our interventional radiology and vascular surgery specialist, performs this type of procedure. During the treatment, a small catheter is threaded through a blood vessel (typically in the wrist or groin) and guided to the specific arteries supplying the inflamed shoulder capsule. Tiny particles are then released to occlude those vessels.
The concept is similar to embolization procedures used for uterine fibroids or prostate enlargement. By reducing blood flow to the inflamed tissue, the body can begin to heal without the constant inflammatory stimulus.
Who Is a Good Candidate for This Procedure?
Not everyone with a stiff shoulder needs embolization. In most cases, conservative treatments are tried first. Dr. Mehran Manouel, our orthopedic surgeon and sports medicine specialist, typically manages patients through physical therapy, anti-inflammatory medications, and corticosteroid injections before considering referral to Dr. Salem.
You may be a candidate for embolization if:
- You have had persistent pain and stiffness for several months despite physical therapy
- Cortisone injections provided only temporary relief
- You want to avoid surgical options like capsular release
- Imaging (such as MRI or ultrasound) shows signs of active inflammation and neovascularization in the capsule
- Your symptoms significantly limit your daily activities
A proper evaluation is essential. During your consultation, the team will review your imaging, assess your range of motion, and determine whether the inflammatory component is still active.
What to Expect on the Day of the Procedure
If you and Dr. Salem determine that embolization is appropriate, here is what the day typically looks like. The procedure is performed on an outpatient basis, meaning you go home the same day.
You will be given local anesthesia at the access site (usually the wrist or groin) and may receive mild sedation to help you relax. The entire procedure generally takes between 45 minutes and one hour.
Using fluoroscopic imaging (a type of real-time X-ray), Dr. Salem navigates the catheter to the target vessels. Contrast dye is injected to confirm the correct location before embolic particles are deployed. You will not feel the particles being released.
Most patients report only mild soreness at the access site afterward. You will be monitored briefly before being discharged with instructions for the rest of the day.
Recovery: What Happens After the Procedure?
Recovery from adhesive capsulitis embolization is generally straightforward. Most patients return to normal daily activities within one to two days. You may experience mild shoulder soreness or a temporary increase in stiffness during the first week, which is a normal part of the healing response.
The key to long-term improvement is continuing your physical therapy program. Embolization reduces the inflammatory driver, but your capsule still needs guided stretching and strengthening to regain full range of motion. Dr. Manouel and his team typically coordinate with Dr. Salem to ensure your rehab plan aligns with the procedure.
Many patients report noticeable pain reduction within two to four weeks, with continued improvement over several months. Results vary from person to person, and the degree of improvement depends on how advanced your condition was at the time of treatment.
How Does Embolization Compare to Other Frozen Shoulder Treatments?
It is fair to ask how this procedure stacks up against the alternatives you have already heard about. Here is a straightforward comparison:
Physical therapy alone: Effective for many patients, especially in early stages. However, some patients plateau or find that pain prevents them from performing exercises effectively.
Corticosteroid injections: Provide rapid pain relief but are temporary. Repeated injections carry risks of tissue damage and are generally limited to three or four per year.
Hydrodilatation: Involves injecting fluid into the joint to stretch the capsule. It can help some patients but does not address the underlying inflammation.
Surgical capsular release: Effective for severe, refractory cases but involves anesthesia, a recovery period, and surgical risks.
Embolization: Targets the inflammatory mechanism directly with minimal downtime. It is not a cure-all, but it offers a middle ground between conservative care and surgery.
Frequently Asked Questions
Is embolization painful?
The procedure itself is performed under local anesthesia, so you should not feel significant pain during the treatment. Mild soreness afterward is common and manageable with over-the-counter pain relievers.
How long do results last?
Many patients experience lasting relief, though individual outcomes depend on the severity of the condition, adherence to physical therapy, and overall health. Some patients may need additional sessions if symptoms recur.
Will I need to stop my medications?
Dr. Salem will review your current medications before the procedure. Blood thinners and certain supplements may need to be paused temporarily.
Is this covered by insurance?
Coverage varies by plan. Our office staff can verify your benefits before scheduling, so there are no surprises.
Can I drive myself home?
If sedation is used, you will need a driver. With local anesthesia alone, some patients are able to drive themselves, but this is determined on a case-by-case basis.
Choosing the Right Team in Queens
When considering a newer procedure like adhesive capsulitis embolization, the provider you choose matters. You want a team that understands both the orthopedic and vascular aspects of the condition and can coordinate your care seamlessly.
At M&S Vascular and Orthopedic Group P.C. in Forest Hills, Dr. Manouel and Dr. Salem work under one roof. That means your orthopedic evaluation, imaging review, and interventional procedure are coordinated without the delays and miscommunications that can happen when providers are scattered across different offices.
If you are in Queens, Brooklyn, or the surrounding areas and have been struggling with a frozen shoulder that is not responding to conservative care, we invite you to schedule a consultation.
Take the Next Step
You do not have to accept limited shoulder mobility as your new normal. If physical therapy and injections have not given you the relief you need, adhesive capsulitis embolization may be the next logical step in your treatment plan.
