Orthopedic surgeons have long faced challenges in soft tissue repair during surgical procedures, with traditional methods often struggling with insufficient fixation strength and slow postoperative recovery. Acumed's newly launched PEEK (polyetheretherketone) suture anchor system aims to provide physicians with a more reliable and efficient solution.
Product Specifications and Features
The PEEK suture anchor system is designed to securely fix soft tissues to bones, suitable for repair, reattachment or reconstruction surgeries in multiple areas including the foot, ankle, hand, wrist, elbow, and shoulder.
The system offers two sizes: 4.5mm and 5.5mm. Each anchor comes pre-loaded with two #2 high-strength FlexBraid® sutures and features an MO-6 tapered needle. This dual-suture design enhances fixation strength and stability while reducing postoperative complication risks.
-
Material advantages:
PEEK demonstrates excellent biocompatibility and mechanical strength, reducing inflammatory responses while promoting bone growth and providing long-term stable fixation.
-
Suture characteristics:
The #2 high-strength FlexBraid® sutures offer superior tensile strength and handling properties, capable of withstanding significant tension to ensure secure soft tissue-to-bone connection.
-
Needle design:
The MO-6 tapered needle features a sharp tip and smooth surface to minimize tissue damage and improve suturing efficiency.
Supporting Instruments
To ensure surgical precision and convenience, the system includes specialized instruments such as drills and taps. These can be purchased either as part of a sterile packaged set with the anchors or separately.
-
Drill:
Designed with bone density and structure in mind, it creates precise channels for anchor placement while minimizing bone damage and enhancing fixation strength.
-
Tap:
Creates threading in the drilled hole to provide engagement surfaces for the anchor threads, ensuring tight integration between anchor and bone.
Clinical Applications
The PEEK suture anchor system is suitable for various soft tissue fixation procedures including:
-
Rotator cuff repair for reattaching torn tendons to the greater tubercle of the humerus
-
Lateral ankle ligament reconstruction to restore joint stability
-
Medial collateral ligament reconstruction in the elbow
-
Triangular fibrocartilage complex (TFCC) repair in the wrist
-
Foot and ankle ligament repairs
Technical Advantages
From a materials perspective, PEEK demonstrates superior biocompatibility and mechanical properties compared to traditional metal anchors. Its elastic modulus more closely matches bone tissue, reducing stress concentration and minimizing bone resorption risks. Being metal-free, it eliminates concerns about allergic reactions or MRI interference.
The dual-suture design provides significantly higher fixation strength than single-suture alternatives, with studies demonstrating markedly improved pull-out resistance. The specialized instrument set enhances surgical precision while potentially reducing operative time and associated risks.
Future Developments
Acumed's introduction of this system provides orthopedic surgeons with an advanced solution for soft tissue fixation. As clinical experience accumulates, the technology may play an increasingly important role in tissue repair. Future developments could include optimized anchor designs, expanded size options, and continued clinical research to further validate long-term outcomes.
