The Kentrospine PSS Pedicle Screw System is intended for posterior, non-cervical fixation as an adjunct to fusion for skeletally mature patients for rigid fixation and stability with following indications: degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies); spondylolisthesis; trauma (i.e., fracture or dislocation); spinal stenoss; curvatures (i.e., scoliosis, kyphosis and/or lordosis); tumor; pseudarthritis; and/or failed previous fusion.

The Kentrospine PSS Pedicle Screw System is a top-loading multiple component, posterior spinal fixation system which consists of PSS Pedicle Screws (Monoaxial, polyaxial), PSS Rods, PSS Locking Cap, and a PSS Crosslink Connectors. The Kentrospine PSS Pedicle Screw System will allow surgeons to build a spinal implant construct to stabilize and promote spinal fusion. Kentrospine PSS Pedicle Screw System components are supplied non-sterile, single use and are made from medical grade. biocompatible Titanium alloy (Ti6Al4V ELI) conforming to ASTM F136-13(2021)- Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications. Various sizes of these implants are available. The PSS Pedicle Screws are available in diameters from Ø4.50mm to Ø7.00mm and in lengths of 25mm to 55mm. PSS Rods are straight, made from titanium and available in 05.50mm diameter with length from 45mm, 55mm, 65mm, 75mm, 85mm, 100mm, 125mm, 200mm, 250mm, 300mm, 350mm, 450mm and 500mm. Specialized instruments are available for the application and removal of the Kentrospine PSS Pedicle Screw System. The instruments are made from SAE 316L stainless steel which is complied with ASTM F899 - 20 Standard Specification for Wrought Stainless Steels for Surgical Instruments.
