9.0MM ACL INTERFERENCE SCREW,CANNULATED
A 9.0mm ACL interference screw, cannulated , likely refers to a medical device used in orthopedic surgery, specifically in procedures related to the anterior cruciate ligament (ACL) reconstruction. Here's a breakdown of its specification and uses:
Specification
- Size: The 9.0mm size indicates the diameter of the screw, which would typically match the size of the tunnel drilled during ACL reconstruction surgery.
- Material: "TIT" likely stands for titanium, suggesting that the screw is made of titanium, a biocompatible material commonly used in orthopedic implants due to its strength and compatibility with the human body.
- Cannulated: The term "cannulated" means that the screw has a hollow center, allowing for passage over a guide wire during insertion. This feature facilitates precise placement of the screw within the bone tunnel.
Uses
- ACL Reconstruction: The primary use of an ACL interference screw is in ACL reconstruction surgery. The ACL is a crucial ligament in the knee, and when it is torn or ruptured due to injury, surgical intervention is often required to restore stability and function to the knee joint.
- Fixation: During ACL reconstruction, the surgeon harvests a graft (often from the patient's own tissue or a donor tissue) and secures it in place within the knee joint using various fixation methods. The interference screw is used to anchor the graft within the bone tunnel created in the tibia (shinbone) or femur (thighbone), providing stability while the graft heals and integrates with the surrounding bone.
- Biomechanical Stability: The interference screw compresses the graft against the bony walls of the tunnel, promoting graft-to-bone healing and providing biomechanical stability to the knee joint.
- Minimally Invasive: The cannulated design allows for minimally invasive insertion of the screw, reducing trauma to surrounding tissues and potentially expediting the patient's recovery.
Overall, the 9.0mm ACL interference screw, cannulated , is a specialized orthopedic implant designed for use in ACL reconstruction surgery to secure grafts and promote stability and healing in the knee joint.
