Standard Guide for Impingement Testing of Total Disc Prostheses |
|
Scope/Abstract1.1 This standard is intended to provide guidance on the evaluation of wear and fatigue characteristics of total disc prostheses under cyclic impingement conditions.
1.2 This guide describes impingement testing of devices with articulating components. The user is cautioned that the methods described herein are intended to produce an impingement condition which may or may not be indicative of clinical performance and which may or may not be consistent with the intended use of the device, and that this should be considered when interpreting the data. Clinically, total disc prostheses should always be implanted per labeling and the manufacturer's instructions for use.
1.3 Impingement has been observed in retrievals among several total disc prosthesis designs; however, impingement is not necessarily associated with device or clinical failure. It is the intent of this guide to investigate possible impingement-induced wear and mechanical failure modes associated with device design, as well as potential mechanical failure modes associated with clinical events such as subsidence, malpositioning, and improper implant sizing. Note that mechanical failure may or may not be associated with functional failure.
1.4 It is recommended that the user define the bearing and non-bearing features of the intervertebral disc (IVD) prosthesis and evaluate the performance of the IVD prosthesis under Mode 1 wear by using Guide F2423 or ISO 18192-1 prior to use of this guide. This standard is not intended to provide guidance on Mode I testing.
1.5 The goal of this guide is to evaluate impingement in IVD prostheses regardless of the intended region of the spine (cervical or lumbar), material or material combinations (ceramic, metal, polymer), and bearing type (fixed or mobile).
1.6 It is the intent of this guide to enable comparison of IVD prostheses with regard to wear and fatigue characteristics when tested under the specified conditions. |
