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 (200), a femoral head component (20), a neck component (30) that may be either integral or modular, and a stem component (11) having a proximal body portion (14) and a distal portion (16). The proximal body portion may include such features as a recess (120) for receiving a portion of the modular neck, a proximal conical flare (50) having a bottom surface with a rounded contour, an anterior metaphyseal tapering flare (80), as well as other features. The distal portion may include a coronal slot (60), a sagittal slot, a helical slot (62), 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. |
