PEEK Interference Screw

Core structure and material
The main materials are medical titanium alloys (such as TC4) and PEEK (polyether ether ketone, which have good biocompatibility and strong corrosion resistance.
The structure is mostly a hollow thread design, some with anti-slip patterns or barbs, the threads can the bite force with the bone tissue, and the hollow design is convenient for accommodating the graft.
Main types
By material: Titanium alloy interface screws, PEEK interface screws the latter has a closer modulus of elasticity to bone tissue, which can reduce stress shielding.
By fixation method: Ordinary thread type, Expansion type, the type can further improve the stability of fixation through postoperative expansion.
Applicable scenarios
It is mainly used for surgical operations such as anterior cruciate ligament reconstruction of knee, rotator cuff repair of the shoulder, and ligament reconstruction of the ankle.
The function is to firmly fix both ends of the graft in the bone tunnel, provide a stable environment for ligament/tendon healing.
Core advantages
Accurate fixation, can closely adhere to the graft and the wall of the bone tunnel, and the strength of fixation.
Compact size, little damage to surrounding tissues, and does not affect the range of motion of the joint.
Most can be left in the body a long time, without the need for secondary surgery to remove (except in special cases).
