Description

Its design allows flexion/extension, lateral bending, rotation, and translation, incorporating a variable center of rotation and controlled translation that is uncoupled from rotation. This allows the anatomical structures to determine the range of motion and enables physiological, facet-guided segment movement.

ROTAIO® is supplied pre-assembled and sterile as a one-piece prosthesis and can be implanted using the established anterior Smith-Robinson technique. Different footprints and heights are available to accommodate varying patient anatomies.

INDICATIONS

• Cervical intervertebral disc replacement at levels C3–C7.
• Patients requiring cervical disc replacement due to radiculopathy and/or myelopathy.
• The affected segment must remain mobile.
• Individual patient condition and suitability must be assessed by the treating surgeon.

EFFECT/TECHNOLOGY

• Restores intervertebral disc height.
• Designed to preserve physiological motion of the treated segment.
• Variable center of rotation corresponding to natural cervical spine motion.
• Controlled translation uncoupled from rotation.
• Allows physiological facet-guided movement.
• Supports flexion/extension, rotation, and lateral bending.
• One-piece prosthesis design.
• Rectangular geometry with a large vertebral endplate contact area.
• Proven toothed endplate design for primary stabilization.
• Increased endplate surface roughness to support bony integration.
• No keel preparation required.
• Endplates manufactured from Ti-6Al-4V titanium alloy.
• Bearing surfaces manufactured from cobalt-chromium-molybdenum (CoCrMo) alloy.
• Available in different footprints and heights to accommodate patient anatomy.
• Pre-assembled and supplied sterile.
