发明名称 Intrinsic stability in a total hip stem
摘要 A prosthetic device and method of using the device is disclosed. The device may include a busing insert, a femoral head component, a neck component that may be either integral or modular, and a stem component having a proximal body portion and a distal portion. The proximal body portion may include such features as a recess for receiving a portion of the modular neck, a proximal conical flare having a bottom surface with a rounded contour, an anterior metaphyseal tapering flare, as well as other features. The distal portion may include a coronal slot, a sagittal slot, a helical slot, or a combination thereof. The above features may be provided for increasing the intrinsic stability of the device and for resisting torsional loads placed on the device.
