7.0MM ACL INTERFERENCE SCREW,CANNULATED
The 7.0mm ACL (Anterior Cruciate Ligament) interference screw, cannulated , is a specialized orthopedic implant used in anterior cruciate ligament reconstruction surgeries. Here's a breakdown of its specifications and uses:
Specification
- Size: The size specification denotes the diameter of the screw, with a diameter of 7.0mm. This dimension is crucial for ensuring proper fit and stability within the bone tunnel.
- Material: The screw is made of titanium , a biocompatible metal known for its strength, durability, and compatibility with the human body.
- Design: The screw features a cannulated design, meaning it has a hollow central channel that allows for the passage of a guide pin during insertion. This design aids in precise placement and fixation of the graft during ACL reconstruction surgery.
Uses
- ACL Reconstruction: The 7.0mm interference screw is primarily used in ACL reconstruction surgeries. During this procedure, the torn ACL is replaced with a graft, typically harvested from the patient's hamstring tendon or patellar tendon. The interference screw is used to secure the graft in place within the bone tunnels drilled in the femur and tibia.
- Biomechanical Stability: The screw provides biomechanical stability by compressing the graft against the bone tunnel walls, promoting graft incorporation and facilitating the healing process. This compression helps to prevent graft laxity and maintain knee stability.
- Cannulated Design: The cannulated design allows for precise placement of the screw over a guide pin, which is inserted through the center of the graft. This facilitates accurate positioning of the graft and screw within the bone tunnels, optimizing fixation and enhancing surgical outcomes.
- Titanium Material Benefits: Titanium interference screws offer several advantages, including biocompatibility, corrosion resistance, and high strength-to-weight ratio. These properties make titanium a preferred material for orthopedic implants, including interference screws used in ACL reconstruction surgeries.
- Surgical Technique: Surgeons use specialized instruments and techniques to prepare the bone tunnels and insert the interference screw during ACL reconstruction surgery. Careful attention to detail is essential to ensure proper graft tensioning and fixation, ultimately leading to successful outcomes and patient rehabilitation.
In summary, the 7.0mm ACL interference screw, cannulated , is a crucial implant used in ACL reconstruction surgeries to provide stable fixation of the graft within the bone tunnels, promoting graft healing and restoring knee stability. Its cannulated design and titanium material offer several advantages, making it a popular choice for orthopedic surgeons performing ACL reconstruction procedures.
