The Mono Sacral Screw XL Single Lock is a specialized orthopedic screw used in spinal fixation systems, primarily for securing the sacrum or lumbar vertebrae. It is a monoaxial screw, meaning the screw head (which accepts the rod) is rigidly fixed to the shaft, providing a fixed angle of fixation. The “XL” designation suggests a long or robust design, and the “Single Lock” refers to the mechanism used to secure the rod within the screw head.
