Wear Properties of a Pyrolytic Carbon Intervertebral Disc Replacement
*Cheema, N; +*Salkeld, S; **Hawkins, N; **Bailey, K; *Cook, S +*Fellowship of Orthopaedic Researchers, Inc., Metairie, LA [email protected] INTRODUCTION: The purpose of this study was to determine if particulate pyrolytic carbon debris was generated during wear simulation of the Regain lumbar nuclear disc replacement articulating on cortical bone. The Regain device is fabricated from pyrolyti...
متن کاملWear analysis of the Bryan Cervical Disc prosthesis.
STUDY DESIGN In vitro wear testing of the Bryan Cervical Disc prosthesis was performed in a cervical spine simulator. The biologic response was assessed in chimpanzee and goat animal models. OBJECTIVE Determine the wear characteristics of the Bryan disc. SUMMARY OF BACKGROUND DATA Large joint arthroplasties fail most commonly by wear and consequent formation of particulate material, which i...
متن کاملCervical Disc Prosthesis Polyethylene Wear Following The ISO Cervical Test
Introduction: Cervical total disc replacement (TDR) procedures are an option for treatment of cervical spinal disc degeneration. The goal of TDR replacement is to replace the painful and degenerated TDR with a new bearing unit to enable pain free motion. A young and active patient population demands a proven durable replacement bearing surface to accomplish this goal. The wear of that surface m...
متن کاملOsteopenia and Total Disc Prosthesis Subsidence: Inclusion/Exclusion Criteria for Total Disc Replacement
BACKGROUND Prosthetic subsidence is an adverse event of disc arthroplasty with a total disc prosthesis. Factors affecting prosthetic subsidence are (1) the size of the prosthetic endplate (footprint), (2) amount of load applied to the spine, and (3) compressive strength of the vertebral bone. The size of the prosthetic endplate has been addressed adequately in the development of the current gen...
متن کاملDoes core mobility of lumbar total disc arthroplasty influence sagittal and frontal intervertebral displacement? Radiologic comparison with fixed-core prosthesis
BACKGROUND An artificial disc prosthesis is thought to restore segmental motion in the lumbar spine. However, it is reported that disc prosthesis can increase the intervertebral translation (VT). The concept of the mobile-core prosthesis is to mimic the kinematic effects of the migration of the natural nucleus and therefore core mobility should minimize the VT. This study explored the hypothesi...
