Collet T, et al. - The purpose of this study is to report 10-year survival and clinical outcomes of a titanium femoral stem with a titanium modular neck in consecutive series. A satisfactory 10-year survival and clinical outcomes were given by the uncemented titanium hip stem with modular titanium neck. Neck modularity enabled restoration of patient-specific femoral offset and limb length thanks to five possible neck configurations, though greater follow up is required to affirm the long-term benefits and safety of this design concept.
