Polyaxial Screw

Glass Agencies presents the Polyaxial Screw, a versatile spinal fixation component widely used in posterior spinal stabilization procedures to support secure anchoring and flexible construct assembly. The Polyaxial Screw features a mobile screw head that allows multidirectional movement, enabling surgeons to align connecting rods more easily during fixation. This flexibility supports smoother rod placement, especially in complex spinal anatomies or multi-level constructs where exact alignment is challenging. Once the rod is positioned, the head can be locked to maintain the final alignment throughout the healing period. The screw is manufactured from biocompatible material suitable for implantation, supporting safe interaction with vertebral bone and surrounding tissues. Its thread configuration supports strong bone purchase, helping maintain stable anchorage under normal physiological loads. The Polyaxial Screw is commonly used in thoracic, lumbar, and cervical spine procedures addressing conditions such as degenerative spine disorders, deformities, trauma, instability, and spondylolisthesis. Its structure supports compatibility with standard spinal rod systems, allowing flexible construct design based on surgical planning. The screw supports controlled insertion using conventional spinal instruments, allowing accurate placement within the pedicle or vertebral body. Its design helps reduce stress during rod engagement, supporting efficient surgical workflow. Radiographic compatibility allows postoperative imaging and follow-up evaluation without significant artifact interference. The Polyaxial Screw supports use in single-level or multi-level fixation systems depending on patient anatomy and procedural requirements. Sterile packaging supports safe handling and readiness for use in operating room environments. The screw supports balanced load distribution across the fixation construct, helping maintain alignment during daily movement and recovery. Glass Agencies maintains strict quality control processes to ensure each Polyaxial Screw meets accepted safety and performance standards for spinal implants. When applied according to surgical protocols and clinical judgment, the screw supports consistent mechanical stability throughout the fusion process. By allowing flexible alignment during placement and secure locking after positioning, the Polyaxial Screw plays a key role in modern spinal surgery.
