Sehnenanker

Sehnenanker, also known as tendon anchors, are medical devices used in orthopedic surgery to reattach torn tendons to bone. They are a critical component in procedures like rotator cuff repair and Achilles tendon repair. The primary function of a Sehnenanker is to provide a stable and secure fixation point, allowing the torn tendon to heal back to the bone.

These anchors are typically made from biocompatible materials such as titanium, stainless steel, or absorbable polymers. They come in various designs, including screw-in anchors, push-in anchors, and suture anchors. The choice of anchor depends on factors such as the size and location of the tear, the quality of the bone, and the surgeon's preference.

The surgical procedure involves drilling a small hole into the bone at the site of the tear. The Sehnenanker is then inserted into this hole, often with sutures already attached. These sutures are then passed through the torn tendon and tied securely to the anchor, pulling the tendon back into its anatomical position on the bone. Over time, as the tendon heals, the bone grows into the anchor, creating a strong and permanent repair.

Sehnenanker have significantly improved the outcomes of tendon repair surgeries, leading to faster recovery times and better functional restoration for patients. While complications are rare, they can include infection, anchor loosening, or failure of the repair. Ongoing research aims to develop even more advanced and minimally invasive anchoring systems.
