Abstract
A system is provided for preparing prosthetic hip implantation. The system includes a first broach, a second broach, and a trial neck having a body portion and a neck portion. A proximal end of the first broach comprises a first base having a first maximum area. The body portion can be releasably coupled to the proximal end of the first broach so as to define a first offset between a medial end of the neck portion and a longitudinal axis of the first broach, or releasably coupled to the proximal end of the second broach so as to define a second offset between the medial end of the neck portion and a longitudinal axis of the second broach. The first offset is smaller than the second offset.
Claims8
A broach for preparing prosthetic hip implantation, the broach comprising:
- a non-metal frame member and a plurality of metal panels circumferentially coupled to the frame member;
- wherein each panel comprises a plurality of cutting teeth, each tooth comprising a cutting hole on the panel and a cutting edge projecting radially outwardly from the cutting hole, and the cutting edges of the plurality of cutting teeth are spaced apart from one another along the panel;
- wherein the frame member comprises a plurality of grooves adjacent to the plurality of cutting teeth of the plurality of panels so as to provide pathways for bone debris to flow through inwardly when the plurality of cutting teeth are urged against and cut a bone tissue;
- wherein a proximal end of broach comprises a base, and a radial cross-sectional area of the broach progressively increases from a distal end of the broach to the base which has a maximum area;
- and
- wherein the proximal end of the broach comprises an opening above a longitudinal lumen enclosed by the frame member.
