ABSTRACT

A 64-year-old man who had previously undergone total hip arthroplasty (THA) with the use of a dual modular (head and neck) total hip implant presented with a mechanical failure at the neck-stem junction three years after the index surgery with a low energy mechanism. The fractured stem was then removed, and a revision stem was implanted in order to restore the ability to ambulate for the patient. We demonstrate and contribute to the growing evidence of failure of modular THA systems at the neck-stem junction.
