Xia 4.5
Category: Thoracolumbar Fixation

A low profile pedicle fixation system enabled by power and navigation technologies


The Xia 4.5 Spinal System combines the power of the Xia cortical cancellous thread pattern with a very low profile tulip head. 
  • Low profile tulip head (12.1mm) allows you to more directly visualize the surgical site
  • Thread pattern optimized for cortical bone at the proximal end and cancellous bone at the distal end
  • Utilizes the same patented1 buttress thread locking technology that has been used clinically for more than 18 years, and is designed to minimize cross threading and splaying of the screw head2
  • Transition rods allow you to transition to ∅3.5, ∅5.5 or ∅6.0 systems
  • Designed to treat a wide range of deformities including adolescent idiopathic scoliosis (AIS), congenital scoliosis, neuromuscular scoliosis, and when combined with the Xia Growth Rod Conversion set, early onset scoliosis (EOS)
  • Rods available in Titanium Alloy and Vitallium (Cobalt Chrome)
  • Compatible with power and navigation platforms
