Claims14
An alignment guide system, comprising:
- a first translation mechanism, wherein the first translation mechanism comprises:
- a housing with a first end and a second end, wherein the housing further comprises:
- a cavity extending into a bottom surface of the housing, wherein at least a portion of the cavity is aligned with a first opening at the first end of the housing and a second opening at the second end of the housing, and wherein at least a portion of a fastening member is received within the cavity;
- at least one window extending from a first side of the housing into the cavity;
- and
- a plurality of markings positioned along at least a portion of the first side of the housing;
- the fastening member extending through the first opening at the first end of the housing and the second opening at the second end of the housing;
- and
- a coupling member secured to the fastening member near the second end of the housing;
- a second translation mechanism coupled to the first translation mechanism;
- and
- a third translation mechanism coupled to the second translation mechanism;
- and
- wherein the first translation mechanism translates in a medial-lateral direction, wherein the second translation mechanism translates in a distal-proximal direction, and wherein the third translation mechanism translates in a varus-valgus direction.
