Abstract
The invention is directed to an alignment device for aligning a prosthetic hip stem implant with an opening formed in a proximal femur.

The alignment device includes an implant engaging portion configured for attachment with the landmark on the hip stem implant. The alignment device also includes a needle indicator connected with the implant engaging portion and having an end which may be positioned relative to the visual alignment mark on the proximal femur, thereby aligning the prosthetic hip stem implant relative to the opening in the proximal femur.
