Total hip arthroplasty head–neck contact mechanics: A stochastic investigation of key parameters
Abstract A variety of design and patient parameters have been implicated in recent reports of fretting corrosion at modular connections in total hip arthroplasty. We sought to identify the relative sensitivity of mechanical fretting to a comprehensive set of parameters such that attention may be foc...
