interface screw

Definition classification: An interfacial screw, also known as an interventional screw, is a term in sports medicine that was released in 2019. It belongs to passive implant devices and is usually a hook-shaped, nail-shaped, door-shaped, or plate-shaped implant, or used in conjunction with implantable sutures. Material It is generally made of metal, high-molecular, composite materials, etc. Common metal materials include stainless steel and titanium alloys, which have high strength and corrosion resistance;-molecular materials such as polyetheretherketone (PEEK) have the advantages of good biocompatibility and elastic modulus close to human bone. Structure: consists of a screw body and threads. The screw body is usually cylindrical, with a sharp end at one end to facilitate penetration of the bone; the threads are used to fix the in the bone, and its design can be adjusted according to surgical needs, such as some screws with self-locking function, and some are designed with gradual and stepped threads to firm fixation. Function: It is mainly used to fix the location of the bone after fracture, bone crack, or osteotomy, to promote the healing and recovery of the. It can also fix the bone block of the tendon or ligament in the bone channel, to achieve a firm connection between soft tissue and bone, and is often used in such as reconstruction of the anterior cruciate ligament of the knee. Clinical application: The interfacial screw has a wide range of clinical applications, and can be to treat various types of fractures, as well as joint Replacement surgery, pelvic reconstruction surgery, and other bone reconstruction surgery. Its implantation process is relatively simple, usually only a small incision, less trauma, and less postoperative pain, which helps patients recover faster.
