Product Description
The concave geometry is designed to match the bone's outer curve. This maximizes the contact area between the button and the cortex, providing superior stability compared to flat designs.
With its ultra-slim profile and curved edges, this button minimizes soft tissue irritation. It is particularly beneficial for procedures on the distal femur or proximal tibia where the skin is close to the bone.
The high-purity titanium allows for clear visibility on post-operative X-rays, enabling surgeons to confirm the "toggled" position and seat of the button on the bone surface.
Used in coracoclavicular (CC) ligament stabilization and distal clavicle repairs where a low-profile footprint is necessary to prevent skin tenting.
Utilized in specialized pelvic and acetabular ligament reconstructions requiring high-load suspensory fixation points.
Primarily indicated for femoral and tibial fixation in ACL/PCL reconstruction. It is also highly effective for syndesmosis stabilization and distal bicep tendon reattachment.

The Concave Button is a small, titanium anchor used to hold ligaments or tendons in place. "Concave" means the bottom of the button is curved inward. This allows it to wrap slightly around the bone, sitting much flatter and more securely than a standard flat button.
It is used whenever a "suspension" technique is needed in surgery. This is most common in ACL Reconstruction, where the button sits on the outside of the bone to hold the new tendon in place. It is also used in the ankle and shoulder to stabilize bones that have been separated due to injury.
The main advantage is Comfort and Stability. Because it fits the curve of the bone, it is less likely to move or "wiggle" after surgery. Its thin design means patients are less likely to feel a "bump" under their skin, which is a major benefit for active patients and athletes.
Biomechanically, the concave design optimizes Stress Distribution. A flat button on a curved bone creates a single "point-load" ($P=F/A$). By matching the curvature, the Concave Button increases the contact area ($A$), which lowers the pressure on the bone cortex. This prevents the button from "sinking" into the bone over time (a process called subsidence) and ensures the graft maintains its tension.
The surgeon drills a small tunnel through the bone. The button is pulled through the tunnel using leading sutures while in a vertical position. Once it exits the other side, the surgeon pulls back, causing the button to "flip" or toggle. The concave side is then seated firmly against the bone surface, providing a permanent anchor for the repair.
The Concave Button is a permanent implant made of titanium, so it does not need to be removed. Patients can proceed with standard rehabilitation. The high stability of the button often allows for Early Weight-Bearing in knee surgeries, as the fixation is mechanically strong enough to handle initial movements without slipping.
The Concave Button is an essential tool for surgeons who prioritize anatomical fit and patient comfort. By combining high-strength titanium with a bone-friendly geometry, it provides the most secure and low-profile fixation available for modern ligament reconstruction.
While everyone's anatomy is different, the Concave Button's low-profile and curved design is specifically engineered to be as unnoticeable as possible compared to standard flat buttons.
Yes. The button is made of high-grade Titanium Alloy (Ti-6Al-4V), which is non-magnetic and 100% MRI-compatible.
No. These are designed to be permanent implants. Removal is only necessary in very rare cases of infection or if a secondary surgery is required.
The TOOLMED Concave Button can withstand forces exceeding 1000 Newtons, which is far beyond the typical stress placed on a joint during the healing process.
The concave shape prevents the button from "rocking" on the bone. This increased stability leads to more consistent graft tension and reduces the risk of the button shifting over time.
