The Spiked Ligament Staple is a heavy-duty orthopedic fixation device engineered for the secure reattachment of soft tissues, such as ligaments and tendons, directly to the bone. Manufactured from medical-grade Cobalt-Chrome or Titanium Alloy, this staple features a wide bridge and multiple inferior Spikes (Teeth) designed to penetrate the soft tissue without causing necrosis. These spikes provide a mechanical "interference fit" that prevents the tissue from sliding or retreating under physiological loads. The low-profile bridge is designed to sit flush, minimizing the risk of overlying soft tissue irritation or bursa formation. TOOLMED Spiked Ligament Staples are available in multiple widths and leg lengths to accommodate various anatomical locations, from the knee to the ankle. By providing uniform compression across the entire tissue-to-bone interface, this staple promotes rapid biological incorporation and provides the immediate stability required for early postoperative mobilization.

Product Description
The integrated spikes on the underside of the bridge "bite" into the ligament, preventing the tissue from sliding under the staple during joint movement. This ensures the repair stays tensioned.
The wide bridge design distributes the downward force evenly across the soft tissue. This maximizes the contact area with the bone, which is essential for successful biological healing.
Available in high-strength alloys that resist corrosion and fatigue, providing a permanent and reliable fixation point that can withstand the stresses of weight-bearing joints.
Used in open or mini-open procedures for biceps tenodesis and specialized rotator cuff augmentations where high-compression mechanical fixation is required.
Utilized for the fixation of capsular tissue or specialized gluteus medius reattachments where suture anchors may not provide sufficient surface area compression.
The primary indication is the fixation of ACL/PCL grafts on the tibia, as well as MCL and LCL reconstructions. It is also widely used for Achilles tendon reattachment and ankle ligament stabilization.

A Spiked Ligament Staple is a medical-grade metal fastener used to pin a tendon or ligament onto a bone. It looks like a heavy-duty construction staple but has tiny, sharp spikes on the bottom. These spikes act like "teeth" that grab the slippery tissue and hold it firmly against the bone so it can heal.
This device is most commonly used in Knee and Ankle Surgeries. For example, when a surgeon rebuilds an ACL, they often use a staple to pin the end of the new ligament to the shin bone (tibia). It is also used in the ankle to fix torn ligaments that help you walk and run without pain.
The main advantage is Anti-Slippage. Without spikes, a ligament could slide out from under a smooth staple. The spikes ensure that the tissue is "locked" in place. It is also very fast for surgeons to use, as it can be hammered into place quickly to provide instant, high-strength fixation.
Biomechanically, the staple creates a Compression Interface. By driving the legs into the bone, the bridge exerts a downward force ($F$). The spikes increase the friction coefficient between the staple and the tissue, preventing Graft Pull-out. The bridge width is calculated to provide enough pressure ($P = F/A$) to promote bone-to-tissue growth without cutting off the blood supply to the healing ligament.
The surgeon prepares the bone surface to encourage healing. The ligament is positioned over the bone, and the staple is placed over the tissue. Using a specialized impactor and a surgical mallet, the surgeon drives the staple legs into the bone until the spiked bridge is tight against the tissue. The depth is checked to ensure it sits flush with the bone surface.
Ligament staples are usually permanent implants. Because they provide such aggressive fixation, patients can often start Early Weight-Bearing therapy. The metal is non-magnetic and MRI-safe. Patients are monitored to ensure the joint stays stable as the tissue biologically bonds to the bone surface beneath the staple bridge.
The Spiked Ligament Staple remains a gold-standard tool for high-tension soft tissue fixation. Its simple but effective design provides the mechanical "bite" and compression necessary to ensure successful outcomes in complex ligament reconstructions.
No. The spikes are designed to be long enough to provide a grip but short enough to avoid cutting through the tissue or causing necrosis (tissue death). They are engineered to provide "interference" rather than "injury."
TOOLMED offers staples in both high-grade Titanium Alloy and Cobalt-Chrome. Titanium is usually preferred for its superior biocompatibility and MRI compatibility.
The bridge is designed with a very low profile. However, in areas with very thin skin (like the side of the knee), some patients may be able to feel the outline of the staple, though it is rarely painful.
The legs of the staple are often "barbed" or divergent to prevent them from backing out. Once the bone heals around the legs, the staple becomes a permanent part of the bone structure.
Our staples are made from non-ferromagnetic materials (Titanium or Co-Cr), making them safe for MRI scans. They will not move or heat up during the procedure.
