Abstract

A broaching instrument and method using a segmented broach head. First and second broach segments are laterally engageable with each other in vivo, and are aligned with each other on a common longitudinal axis when so engaged. The method involves making a small anterior incision adjacent a patient's femur, inserting the broach segments sequentially through the anterior incision, interconnecting the plurality of broach segments in vivo, connecting the broach handle to the broach segments, and broaching the proximal medullary canal with the assembled multi-part broach instrument.
