Semi-Polyaxiality Screws 25D screws restrict motion to half polyaxial range, combining benefits of polyaxial screws (ease of rod insertion) and monoaxial screws. Coronal & Axial Correction The 25D screws are designed to provide polyaxial freedom in the cranial/caudal plane, but restrict motion in the medial/lateral plane to enable more control of the vertebra during reduction maneuvres. Apical Vertebra Derotation Restricted motion of the 25D screws can be directed medially or laterally, enabling direct rotation of vertebra and allowing a safe and efficient direct or “en bloc” (not available in the US) vertebra rotation. Identification of the Fixed Area The restricted motion side is indicated by a laser etch on the screw head
