ABSTRACT:
A broach instrument for preparing the proximal medullary canal of a femur for receiving a hip stem implant includes lateral and medial broach segments that may be assembled and disassembled along a longitudinal plane of separation defined by longitudinal sliding surfaces. A respective longitudinal shaft is connected to a proximal end of each broach segment. Each longitudinal shaft has a respective impact head connected to a respective proximal end. The broach segments and/or shafts positively engage one another to resist lateral separation of the broach segments. Each broach segment may be inserted separately and sequentially through a minimal posterior incision and through the gluteus maximus and then be assembled within the patient for broaching.
