What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores whether early surgery or physical therapy is more effective for teens with a first-time shoulder dislocation. It compares arthroscopic stabilization, a minimally invasive surgery, with rehabilitation involving a sling followed by physical therapy. The goal is to determine which method better prevents future shoulder dislocations, reduces pain, and improves shoulder function. Teens aged 12-18 who have recently experienced their first shoulder dislocation may be suitable candidates. As an unphased trial, this study provides teens the opportunity to contribute to important research that could enhance treatment options for shoulder dislocations.

Will I have to stop taking my current medications?

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.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that arthroscopic stabilization surgery is generally safe and effective for treating shoulder dislocations. It often results in good outcomes, with a low risk of the shoulder dislocating again. Serious complications after the surgery are rare, with only about 3.8% of patients requiring another surgery within a year.

Rehabilitation is also safe, with a low risk of recurrence. For instance, one study found that only 2% of participants experienced another dislocation after rehab. These findings suggest that both treatment options are well-tolerated and carry a low risk of serious issues. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about comparing arthroscopic stabilization and rehabilitation for shoulder dislocation because each approach offers unique benefits. Arthroscopic stabilization involves a minimally invasive surgery that directly repairs the tissues in the shoulder to prevent future dislocations, potentially offering a more permanent solution compared to traditional methods like immobilization and physical therapy alone. On the other hand, the rehabilitation approach focuses on strengthening the shoulder through a structured regimen of immobilization followed by physical therapy, which is less invasive and avoids surgical risks. Understanding which method provides better long-term stability and recovery could significantly enhance treatment outcomes for patients with shoulder dislocations.

What evidence suggests that this trial's treatments could be effective for shoulder dislocation?

This trial will compare arthroscopic stabilization surgery with rehabilitation, which includes a period of immobilization followed by physical therapy, for treating shoulder dislocation. Research has shown that arthroscopic stabilization surgery often results in fewer repeat dislocations and better shoulder stability over time. Studies indicate that individuals undergoing this surgery are less likely to experience another dislocation compared to those who do not. In contrast, a common non-surgical approach involves immobilization and physical therapy, but surgery generally proves more effective at preventing future shoulder instability. For teenagers and young adults, surgery is often considered more effective at preventing future shoulder problems. Overall, while both surgical and non-surgical methods aim to improve shoulder health, arthroscopic stabilization may offer more reliable long-term results in preventing repeat dislocations. ^{1 6 7 8 9}

Trial Overview

This trial tests early arthroscopic stabilization surgery against rehabilitation (immobilization followed by physical therapy) in adolescents after their first shoulder dislocation. It aims to see which method better prevents repeat dislocations, reduces pain, and improves shoulder function over one year.

How Is the Trial Designed?

Group I: Arthroscopic stabilization Active Control 1 Intervention

Patients will have an initial evaluation with a diagnostic shoulder arthroscopy and examination under anesthesia will be performed to confirm the degree of anterior instability and assess range of motion of the affected shoulder. Diagnostic arthroscopy will commence with the use of 3 standard shoulder portals (posterior viewing and two anterior working portals for suture passing), and a detailed arthroscopic examination will be performed. Once the soft tissue tear (including the labrum, and capsule labrum ligaments) is identified, it will be mobilized using a rasp or elevator and a burr will then be used to create a surface for a bleeding bone bed. Capsulolabral repair will then commence with the labrum fixed to the glenoid using suture anchors (the Bankart repair). Following surgery, subjects in this group will follow the same rehabilitation protocol as the comparison group.

Group II: Rehabilitation including a period of immobilization followed by physical therapy Active Control 1 Intervention

Subjects in this group will use an internal-rotation shoulder immobilizer, using a standard sling for 6 weeks from the day of enrollment. Subjects will be advised to maintain range of motion (ROM) in the elbow and wrist during this period of time. The immobilizer can be removed for passive pendulum exercises and elbow ROM during the period of immobilization up to 4 times per day. Formal physiotherapy commences at 4 weeks post-enrollment, with a goal of return to activities or sport at 6-months post-enrollment.

In a retrospective study of 18 patients who underwent arthroscopic stabilization for recurrent anterior shoulder dislocation, the procedure resulted in good overall outcomes, with 14 out of 16 patients reporting minimal or no pain and a mean Constant score of 80.

There were no cases of re-dislocation or major complications, indicating that arthroscopic stabilization is a safe and effective treatment option for recurrent shoulder instability.

Arthroscopic management of anterior instability of the shoulder. Ozorak, M., Kokavec, M., Svec, A.[2016]

Arthroscopic stabilization of the unstable glenohumeral joint is a promising alternative to open surgical procedures, particularly for patients with recurrent dislocations and labral detachment, but it currently shows a higher rate of recurrence compared to the open Bankart procedure.

While arthroscopic techniques offer benefits like shorter hospital stays and less soft tissue trauma, more long-term studies are needed to fully evaluate their efficacy and to compare them directly with open techniques to determine the best approach for shoulder stabilization.

Recent advances and perspectives on arthroscopic stabilization of the shoulder. Cash, JD.[2021]

In a long-term follow-up study of 67 patients who underwent arthroscopic stabilization for shoulder dislocations, 35% experienced at least one redislocation after 8 to 10 years, indicating a notable recurrence rate despite initial stabilization.

Patients who did not experience redislocations reported significantly better shoulder function, highlighting the importance of preventing redislocations for optimal recovery; additionally, using fewer than 3 suture anchors and the presence of a Hill-Sachs defect were associated with a higher risk of redislocation.
