S140 Interbody System

S140 Interbody System

The S140 Interbody System, used in conjunction with the S100 Pedicle Screw System, provides a comprehensive solution for stabilization of the lumbar spine. Manufactured by Calvary Spine, LLC from PEEK-OPTIMA®†, these interbody devices were designed for PLIF/TLIF and either unilateral or bilateral placement.

S140 Interbody System

Anatomic design features include a tapered “bullet nose” geometry, curved contour, and 8-degree angle of lordosis. Device sizes options range from 7 – 15 mm (anterior height).

Features and Benefits


  • Proven long-term biocompatibility
  • Modulus of elasticity in the range of cortical and cancellous bone.

02 Tapered ‘bullet-nose’ design

  • Eases insertion
  • Protects against violation of the endplate

03 Inferior and superior surface ridges

  • Resists implant migration
  • Provides substantial surface area to prevent subsidence

04 Large graft windows and graft volume

  • Facilitates bony integration

05 Central I-beam design

  • Resists de-formation during placement
  • Allows substantial bone graft compartments

06 Curved Contour

  • Approximated the geometry of the disk space disc space periphery, allowing contact with the most dense endplate bone

07 8 Degrees of Lordosis

  • Allows restoration of segmental sagittal alignment and coronal obliquity

08 Radiographic Markers

  • Embedded tantalum pins show implant position on x-ray, without obscuring the view of the healing fusion

09 10 and 25 degree insertion angles

  • Permits flexibility in surgical approach, minimizing neural retraction

10 Efficient instrumentation

  • Intuitive, ergonomic insertion tools
  • Trial spacers to determine optimal implant size and confirm position radiographically

11 Range of Sizes

  • 7mm – 15mm anterior heights
