Separated Shoulder: When to Use a Brace

A separated shoulder-often the result of a fall, sports collision, or accident-can be painful and limit your ability to move your arm. This injury, also called an AC joint separation, occurs when the ligaments connecting the collarbone (clavicle) to the shoulder blade (scapula) are stretched or torn. While mild cases may heal with rest, more moderate or severe separations often benefit from targeted stabilization with a shoulder separation brace or AC joint support.

Below, we explain when bracing makes sense, what benefits it offers, and how to choose the right level of support.

When Should You Use a Shoulder Separation Brace?

A brace or support can be useful at several points during recovery:

1. Immediately After Injury (Acute Phase) In the first few days after a separated shoulder, swelling, inflammation, and instability are common. A shoulder brace for AC joint separation can help immobilize the joint, minimize further movement, and reduce pain.

2. During Rehabilitation As your injury heals, a brace can allow controlled motion while protecting the AC joint. This can be especially helpful if you need to resume light daily activities before full recovery.

3. Returning to Sports or Work Athletes, manual laborers, or anyone returning to overhead activities may benefit from wearing a shoulder support for separated shoulder to add stability and prevent re-injury.

If you’re wondering how long it might take to get back to normal activities, our AC Joint Separation Recovery Timeline outlines what to expect at each stage of healing.

Benefits of Using a Brace for Shoulder Separation

• Stabilizes the AC joint so ligaments can heal without constant strain.

• Reduces pain by limiting aggravating movements.

• Improves posture during recovery to avoid compensatory shoulder and neck issues.

• Boosts confidence in returning to activity.

Types of Shoulder Braces for AC Joint Injuries

• Immobilizers - Hold the arm close to the body for maximum rest.

• Figure-8 Straps - Pull shoulders back to stabilize the joint.

• Adjustable Compression Supports - Offer targeted pressure to the AC joint while allowing controlled movement.

When Not to Use a Brace

While bracing can be beneficial, it's not always the right solution. Avoid long-term overuse, which can lead to shoulder stiffness or muscle weakness. Severe separations (Grade III or higher) may require medical intervention or surgery-your healthcare provider will guide you.

Choosing the Right Brace

For AC joint injuries, look for a brace that offers both compression and adjustable stabilization. Some designs include strapping systems to hold the joint in place while still allowing functional movement.
