AC Joint Double Button Implant

The AC Joint Double Button Implant is a surgical device that stabilizes the injured AC joint. It uses two titanium buttons and UHMWPE sutures for anatomical ligament reconstruction. This design restores shoulder stability after acute or chronic acromioclavicular dislocations. The system allows open or arthroscopic application with minimally invasive surgical techniques. It provides precise joint reduction while reducing soft tissue disruption during shoulder surgery.
Because of its minimally invasive design, the implant can be deployed using open or arthroscopic techniques. Allowing precise joint reduction while minimizing soft tissue disruption.

Usage

• For treating AC joint separations / dislocations. Especially intermediate to high-grade injuries (e.g. Rockwood classification type III to VI).
• For acute injuries (shortly after trauma) as well as some chronic dislocations where ligamentous support is lost.
• In some cases of distal clavicle fractures associated with AC joint instability.

Key Features & Advantages

• The double-button configuration ensures stable CC ligament reconstruction with natural anatomical alignment.
• High-strength UHMWPE sutures provide strong fixation and maintain reliable stability during healing.
• The minimally invasive approach uses small incisions and reduces soft tissue disruption effectively.
• Low-profile titanium buttons minimize tissue irritation compared to larger plates or metal hardware.
• Dual fixation distributes biomechanical load evenly and helps reduce stress on surrounding structures.
• Facilitates early mobilization — stable fixation allows early passive/active-assisted rehabilitation, which can improve functional recovery.

Why It’s a Good Option?

The AC Joint Double Button Implant provides a modern, anatomically oriented and minimally invasive solution. It treats moderate to severe AC joint dislocations or distal clavicle-related instability effectively. Its hardware design (titanium buttons + high-strength sutures) offers stable, reproducible fixation. While reducing soft tissue irritation and facilitating early functional recovery. Clinical reports demonstrate good functional outcomes, pain reduction, and satisfactory radiographic restoration of joint alignment. However, like all surgical techniques, success depends on correct surgical technique, patient selection, and careful postoperative rehabilitation.
