Abstract：
:In the current era of total hip arthroplasty (THA), orthopedic surgeons have several fixation options at their disposal. The modern monoblock prosthesis, introduced by Dr. Sir John Charnley, has seen many modifications since its inception in the 1970s and continues to be the most commonly used prosthesis style for primary and revision THA. Proximal modular sleeve technology was introduced in 1967 by Konstantin Sivash, modifying his original 1956 Sivash Stem design. The design is now known as the S-ROM, and although design modifications continue to date, the fundamental structure of the S-ROM remains essentially unchanged. Several other proximal modular prostheses are now currently available for use in THA. Although this similarity in design enables considerable surgical flexibility, it also links their potential for catastrophic failure. This aim of this article was to present a brief history of proximal modularity in THA and to add to the small body of literature regarding catastrophic failure in modular hip implants, including its proposed etiologies including micromotion, fretting and corrosion.
