Lumbar-sacral vertebra pedicle screw TI-5.5 / 6.0

thoracic-lumbar vertebrasacro-iliac jointcannulated

This system consists of pedicle screws, titanium rods, set screws, and other components. The pedicle screws feature a through-cannulation design along the central axis of the screw body, enabling minimally invasive percutaneous pedicle screw fixation. The system offers reduced blood loss, minimized muscle and soft tissue dissection, less postoperative pain, faster recovery, smaller incisions and scars, and shorter hospital stays. It also maintains the advantages of satisfactory reduction and strong fixation. Early ambulation can facilitate rehabilitation and support an earlier return to work. Spinal minimally invasive surgery is characterized by precise operation, minimal tissue damage, rapid recovery, and small incisions. Primary Function The system is designed to restore vertebral alignment and physiological spinal curvature while bearing partial or full physiological loads in patients with conditions such as vertebral fractures, lumbar disc herniation, lumbar spinal stenosis, and spondylolisthesis. Through a posterior surgical approach, pedicle screws are implanted into the vertebral bodies through the pedicles of the thoracolumbar vertebrae. Manipulation of the screws enables distraction, compression, lifting, and reduction of the vertebrae, helping restore anatomical position and spinal curvature. The rod is passed subcutaneously into the U-shaped slots of the pedicle screws using specialized insertion instruments and secured with set screws. This creates a stable fixation construct that provides a favorable biomechanical environment for thoracolumbar spinal fusion and fixation. All components are made of TC4 titanium alloy.
