ABSTRACT:
Broaching instruments divided into multiple parts to reduce the size of incisions necessary to perform a total hip arhroplasty, minimizing trauma to tissue surrounding the hip joint. One approach is to divide the broach head into first and second segments for insertion through posterior and anterior incisions, respectively, and interconnection within the patient. Methods of preparing the proximal medullary canal of a femur for receiving a hip stem implant utilize the multi-part broaching instruments and two-incision techniques to introduce the broaching instruments into the patient for broaching the canal in preparation for receiving the implant.
