What is the purpose of this trial?

This trial explores a new treatment for rotator cuff injuries by combining embolization (blocking certain blood vessels) with physical therapy, compared to physical therapy alone. Researchers aim to determine if this combination reduces shoulder pain and improves arm function over a year, while also assessing its safety. The trial seeks individuals with moderate to severe shoulder pain lasting more than six months who have not found relief from traditional treatments. Participants must be willing and able to undergo both angiography (a type of imaging test) and physical therapy sessions. As an unphased trial, this study offers a unique opportunity to contribute to innovative research that could lead to new treatment options for rotator cuff injuries.

Do I need to stop my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What prior data suggests that embolization is safe for treating rotator cuff injury?

Research has shown that embolization, a procedure used to treat blood vessels, is generally safe for shoulder issues. In studies involving individuals with long-term shoulder pain, embolization proved to be safe. For instance, one study found that patients reported less pain and better joint movement after the treatment. Another study revealed that most patients experienced significant pain relief and improved function within a month of undergoing embolization. These findings suggest that embolization is well-tolerated and can help reduce shoulder pain without serious side effects. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about embolization for rotator cuff injuries because it offers a novel approach by directly targeting the abnormal blood vessels causing inflammation and pain. Unlike standard treatments like physical therapy or surgery, embolization uses a microcatheter to deliver an embolic agent that blocks these problematic blood vessels, potentially reducing pain and inflammation more effectively. This method allows for targeted treatment with minimal invasiveness, which could lead to faster recovery times and fewer complications compared to more traditional surgical options.

What evidence suggests that embolization might be an effective treatment for rotator cuff injury?

Research has shown that transcatheter arterial embolization (TAE), a procedure participants in this trial may receive, can greatly reduce shoulder pain and improve movement. In one study, 80% of patients felt less pain, and 73% saw significant improvement within four months. Another study found that patients experienced noticeable pain relief and better function just one month after TAE. All studies noted pain reduction and improved mobility in less than six months. This suggests that TAE could help people with long-term shoulder pain that hasn't improved with other treatments. ^{1 2 3 4 5}

• Embolization

Trial Overview

The study compares the effectiveness of transcatheter arterial embolization (TAE) combined with physical therapy (PT) versus PT alone in reducing shoulder pain over a period of 12 months. It also evaluates safety and changes in function and disability scores.

How Is the Trial Designed?

Group I: Embolization Experimental Treatment 2 Interventions

Angiography will be performed to identify hyperemic neovasculature arising from one or more of branch shoulder arteries. After localizing the abnormal neovessels a microcatheter will be inserted coaxially and selectively placed in the targeted artery(ies). The abnormal vessels will be embolized with Lipiodol emulsion (Guerbet, Villepinte, France) The embolic agent will be used under an investigational device exemption from the FDA. The embolic will be injected in small volume increments until blood flow stagnates in the target artery(ies). Angiography and embolization will be repeated until the hyperemia is markedly reduced as demonstrated on digital subtraction angiography. Subjects will participate in structured physical therapy consisting of 3 months of eccentric strength training. This twelve-week program will consist of 4 PT sessions at week 0, week 4, week 8, and week 12.

Group II: Physical Therapy Active Control 1 Intervention

Subjects will participate in structured physical therapy consisting of 3 months of eccentric strength training. This twelve-week program will consist of 4 PT sessions at week 0, week 4, week 8, and week 12.

In a study involving 28 rats with rotator cuff injuries, using a cannulated humeral implant to deliver local bone marrow did not significantly improve tendon-to-bone healing compared to a solid implant.

While there was evidence of intraluminal bone growth in the cannulated implants, the small size of the rat models may have limited the effectiveness of bone marrow delivery, suggesting that further research in larger animals is needed.

The refined 'SCOI Row' technique for rotator cuff repair, utilizing a single row of triple-loaded anchors, has shown over 90% healing rates on postoperative MRI and excellent patient-reported outcomes, indicating its efficacy.

The technique enhances biological healing through the creation of bone marrow vents, which deliver growth factors and cells to the repair site, improving the chances of successful tendon regeneration.

A study analyzing 60 reports from the FDA's MAUDE database on radiofrequency ablation (RFA) for leiomyomas found that the most common adverse event was infection, highlighting potential safety concerns with this treatment.

Of the injury cases reviewed, 34.9% required additional surgical intervention, indicating that while RFA is a novel treatment option, there are significant risks that necessitate careful monitoring and postmarket surveillance.

A total of 497 adverse events related to synthetic male slings were reported to the FDA from 2009 to 2018, with the majority classified as injuries (95.4%) and the most common issues being urinary incontinence (46.7%) and sling erosion (9.1%).

Despite concerns surrounding urogynecologic mesh, there was no significant increase in adverse event reports for male slings following FDA warnings, indicating that the controversy did not impact reporting rates, highlighting the need for further clinical studies to assess safety.

A study involving 60 patients with rotator cuff disease found that allogeneic platelet-rich plasma (PRP) injections are safe and do not lead to treatment-related adverse events.

While PRP injections did not show immediate superiority over corticosteroid injections in pain relief, they resulted in significantly better long-term outcomes in terms of overall function and external rotation at 6 months, indicating a gradual improvement in shoulder function compared to the quicker but less sustained response from corticosteroids.

Triamcinolone acetonide (TAA) treatment in isolated human rotator cuff tendon cells led to significant cellular degeneration, reduced collagen I production, and decreased cell proliferation, which may impair tendon healing.

Thromboembolic events are the most common adverse occurrences in endovascular neurosurgery, with incidence rates varying from 2% to 61%, highlighting the need for effective prevention strategies, although optimal use of anticoagulants remains unclear.

Groin-site hematomas are the most frequent access-related complications, with an incidence of 9% to 32%, and there is a lack of standardized protocols for prevention, indicating a need for systematic guidelines to improve safety in neurosurgical practices.
