Integrated long tail nail design More stable than extended casing Convenient to plant sticks and tighten the top wire Half-way double thread Fixed stronger Faster nail placement Suitable for different bone types Tail design The tail can be broken off at the end the long tail Prevent long tail deformation Negative angle reverse thread Reduce lateral stress Increase vertical pressure and holding powerWhat is minimally invasive pedicle screws? Unlike traditional spinal surgery, which requires incisions up and down the middle of the back and muscle retraction, a minimally invasive procedure uses tiny cameras and smaller skin incisions. Surgeons are able to work precisely in smaller surgical fields. Indications Herniated disc. Spinal stenosis (narrowing of the spinal canal) Spinal deformities (like scoliosis) Spinal instability. Spondylolysis (a defect in a part of lower vertebrae) Fractured vertebra. Removal of a tumor in the spine. Infection in the spine. Benefit Minimally invasive spine surgery uses small incisions, compared to large openings on the back and neck. As a result, the risk of infection is drastically reduced and blood loss is minor. Also, with limited intrusion there is little to no muscle damage that occurs. Causes of Fractures Spinal fractures may occur due to a variety of factors. The most common cause is related to trauma such as high velocity car accidents, fall from height, or high impact sports. Other causes may include pathologic fractures related to osteoporosis or cancer.Thread start Blunt design Can prevent wrong threading Easy implantation process Curved titanium rod Pre-defined physiological curve Reduce intraoperative bending Single-axis Screw Nail base can be rotated 360 Easy to penetrate the rod Polyaxial Screw Greater range of motion Reduce nail head collision More flexible structural installation
