Pedicle Polyaxial Screw surgical technique

The Pedicle Polyaxial Screw is a vital component in spinal fixation procedures, providing stability, alignment, and support for the vertebral column. This surgical technique is widely used in spinal fusion, deformity correction, and trauma cases. Surgical Technique Overview 1️⃣ Preoperative Planning Perform radiographic imaging (X-ray, CT, or MRI) to assess spinal anatomy. Identify entry points and trajectory for optimal screw placement. 2️⃣ Patient Positioning Place the patient in a prone position on a radiolucent table. Ensure proper spinal alignment and use fluoroscopy for guidance. 3️⃣ Pedicle Preparation Identify the pedicle entry point using anatomical landmarks. Use a pedicle awl or burr to create an entry hole. Probe the pedicle with a pedicle finder to establish the trajectory. 4️⃣ Screw Insertion Tap the pedicle to prepare the bone for screw placement. Insert the polyaxial pedicle screw at the correct angle using a screwdriver. Verify screw positioning with fluoroscopic imaging. 5️⃣ Rod Placement & Fixation Connect the screws using a titanium rod to stabilize the spinal segments. Secure the construct using locking caps. 6️⃣ Final Adjustments & Closure Perform final tightening of all components. Confirm alignment and stability. Close the incision in layers and apply a sterile dressing. Key Advantages ✔️ Multi-Angular Flexibility – Allows better alignment with spinal anatomy. ✔️ Strong Fixation – Provides stability in fusion surgeries. ✔️ Minimally Invasive Options – Reduces soft tissue disruption. ✔️ Biomechanical Efficiency – Enhances load distribution for long-term success. 💡 Pedicle Polyaxial Screws play a crucial role in spinal stabilization, offering surgeons precision and adaptability for successful patient outcomes.
