Abstract
A version adjustment instrument is utilized with modular femoral components, including a modular stem component having a coronal slot and/or a bowed portion and a modular body component attachable to the modular stem component in a substantially fixed orientation relative to the coronal slot or bowed portion. The instrument includes a base with a face surface having a plurality of adjacent angle markings. A body component support has a first coupler formed to engage the modular body component in a substantially fixed orientation relative to the body component support. A stem locator has a second coupler formed to engage one of either the coronal slot or bowed portion (if any) of the modular stem component in a substantially fixed orientation relative to the stem locator. One of the body component support or the stem locator is connected to the base at a position away from the face surface in a substantially fixed orientation relative to the angle markings. The other of the two is rotatably mounted to the base about an axis of rotation and includes a pointer projecting away from the axis of rotation with a portion adjacent the angle markings.
