An apparatus () for removing bone material comprises a distal cutting instrument () and a proximal cutting instrument (). The distal cutting instrument has at least one first cutting edge (), a shoulder (), and a shaft portion (). The shaft portion () has an anti-rotation feature. The at least one first cutting edge () removes bone material when moved in a first direction. The proximal cutting instrument () is removably attached to the shaft portion (). The proximal cutting instrument () has a first end portion () and a second end portion (). The second end portion () contacts the shoulder () of the distal reamer () when the proximal reamer is mounted to the shaft portion (). The proximal reamer () has at least one second cutting edge () and an aperture. The aperture is adapted to receive the anti-rotation feature of the shaft portion () of the distal reamer (). The at least one second cutting edge () removes bone material when moved in a second direction.

Femoral reaming system and method of performing trial reduction

Methods and devices for performing hip replacement surgery are described. According to one embodiment, a method comprising providing an incision locator, the incision locator comprising at least one location indicator and at least one incision indicator, the location indicator configured to align with a central axis of the femur, and the incision indicator configured to guide a proper placement of a surgical incision when the location indicator is aligned, aligning the location indicator with at least one anatomical feature of the patient, making an incision in the proper location as guided by the incision indicator, and completing the surgical procedure is described.

Hip replacement incision locator

Methods and devices for performing hip replacement surgery are described. According to one embodiment, a method comprising providing an incision locator comprising a first wing and a second wing, the first wing adapted to be oriented generally along the femoral axis of a femur forming the hip on which the surgery is being conducted, positioning a proximal portion of the first wing adjacent to the greater trochanter, positioning other portions of first wing generally parallel to the femoral axis, indicating a proper placement of an incision based at least in part on the position of the second wing of the incision locator, performing an incision using at least one incision guide in at least one of the first and second wings, and completing the surgical procedure is described.
