4.0MM LOW-PROFILE CANCELLOUS SCREW
A 4.0mm low-profile cancellous screw is a specific type of surgical screw commonly used in orthopedic procedures. Here's a breakdown of its specification and uses:
Specification
- Size: The "4.0mm" refers to the diameter of the screw shaft, indicating its size. This measurement is crucial as it determines the compatibility with other implants and instruments used in the procedure.
- Low-profile design: The term "low-profile" suggests that the screw has a reduced height or prominence once implanted. This design feature is often desirable to minimize soft tissue irritation and facilitate better patient comfort.
- Cancellous screw: Cancellous screws are designed with a thread pattern optimized for gripping into spongy or cancellous bone, which is typically found at the ends of long bones. This type of screw provides excellent fixation in bone with a less dense structure.
- Material: The abbreviation "TIT" likely stands for titanium, indicating that the screw is made of titanium or a titanium alloy. Titanium is commonly used in medical implants due to its biocompatibility, strength, and resistance to corrosion.
- Specification: The screw's specification may include details such as thread pitch, length, and head type. These specifications ensure proper selection and application of the screw for a specific surgical procedure.
Uses
- Orthopedic Surgery: This type of screw is commonly used in orthopedic surgeries involving bone fixation, such as fracture repair, osteotomies, and joint reconstruction.
- Bone Grafting: Cancellous screws are often used in bone grafting procedures to secure bone grafts or bone graft substitutes in place while they heal and integrate with the surrounding bone.
- Arthrodesis: In procedures where joint fusion (arthrodesis) is performed to stabilize a joint, cancellous screws may be used to immobilize the bones until fusion occurs.
Overall, the 4.0mm low-profile cancellous screw is a specialized orthopedic implant designed for secure fixation in cancellous bone with minimal prominence and excellent biocompatibility, making it suitable for various orthopedic procedures.
