Abstract
An alignment guide for aligning instrumentation along a proximal femur includes a neck portion configured to wrap around a portion of the neck of the femur, a head underside portion configured to abut a disto-lateral portion of the femoral head and a medial head portion configured to overlie a medial portion of the head. Portions of the guide can have an inner surface generally a negative of the femoral bone of a specific patient that the guide overlies; such surfaces can be formed using data obtained from the specific patient. The neck portion can be configured to rotationally stabilize the guide by abutting and generating a first gripping force on the neck. The femoral head portions can be configured to grip the head portion of the femur and can support a bore guide that is configured to guide an instrument to the femur in a specified location and along a given axis.
