Modular femoral neck fracture after THA: Comparison of two different stem-neck alloys
Author(s): Monika Jenko
An alarmingly large number of femoral modular stems of titanium alloy neck suffer from premature fractures. The cobalt-chromium neck was introduced for its better wear and mechanical properties, although it fails even earlier. Until now there were no direct comparisons between two different femoral modular necks for the same type of stem implant.
