Posterior Spinal Inter-Fixation System (Minimally Invasive Spine System) treats disc degeneration, spondylolisthesis, spinal stenosis, fractures, tumors and pseudarthrosis. It uses the multifidus-longissimus intermuscular plane with less bleeding, nerve irritation and postoperative back pain.
Integrated Long Tail Screw Design: More stable than extended sleeves, convenient for rod insertion and set screw tightening.
Breakable tail tip design avoids long tail deformation that interferes with operations.
Negative-angle reverse threads reduce lateral stress and boost vertical compression and gripping force.
Half-length dual threads offer firmer fixation and faster insertion, adapting to patients with varying bone quality.
Blunt thread start prevents cross-threading for smooth implantation.
Curved titanium rods pre-shaped with physiological curvature reduce intraoperative bending.
Uniaxial pedicle screw: 360° rotatable head facilitates rod passage.
Polyaxial pedicle screw features wider range of motion, less head collision and more flexible assembly.
