Abstract
A varus-valgus alignment instrument includes a body having a bone contact surface for contacting a distal femur and an opening extending through the body and bone contact surface. The opening is sized to receive an elongate shaft therein. An alignment member is moveably attached to the body and has first and second openings therethrough. The first and second openings are sized to receive the elongate shaft and are interchangeably positioned in alignment with the opening of the body.
Claims20
An orthopedic referencing guide system, comprising:
- a guide body having a first surface, a second surface opposing the first surface, and a body opening extending through the first and second surfaces;
- and
- first and second bushings separately formed from the guide body and each having a first end, a second end opposing the first end, a bushing opening extending through the first and second ends, the bushing opening defining a longitudinal axis thereof, and a pair of notches formed in an exterior of the respective first and second bushings and offset from each other in a longitudinal direction such that one notch is closer to the first end than the other notch,
- wherein the first and second bushings are each receivable within the opening of the guide body,
- wherein, when the first bushing is received within the body opening, the pair of notches thereof engage the guide body such that the longitudinal axis of the opening of the first bushing intersects a plane defined by the first surface of the guide body at a first angle, and
- wherein, when the second bushing is received within the body opening, the pair of notches thereof engage the guide body such that the longitudinal axis of the opening of the second bushing intersects the plane of the first surface at a second angle different from the first angle.

An orthopedic referencing guide system, comprising:
- a guide body having a first side having a bone contact surface, a second side opposing the first side, and a body opening extending through the first and second sides;
- and
- first and second bushings separately formed from the guide body and having a pair of notches engageable to the guide body from within the body opening, the first and second bushings each having a length and a bushing opening extending entirely through the respective first and second bushings along the length thereof, the bushing opening defining a longitudinal axis thereof and the pair of notches being disposed at opposite sides of the longitudinal axis and offset in a direction extending along the longitudinal axis,
- wherein, when the first bushing is engaged to the guide body from within the body opening, the longitudinal axis of the opening of the first bushing is oriented relative to the bone contact surface of the guide body at a first angle, and
- wherein, when the second bushing is engaged to the guide body from within the body opening, the longitudinal axis of the opening of the second bushing is oriented relative to the bone contact surface of the guide body at a second angle.

An orthopedic referencing guide system, comprising:
- a guide body having first and second sides thereof, the first side having a bone contact surface;
- a first bushing separately formed from the guide body and having a pair of notches formed in an exterior thereof, and a first opening extending therethrough, the first opening defining a longitudinal axis thereof, the first bushing being engageable to the guide body via the pair of notches such that the longitudinal axis of the first opening has a first orientation relative to the bone contact surface;
- and
- a second bushing separately formed from the guide body and having a pair of notches formed in an exterior thereof, and a second opening extending therethrough, the second opening defining a longitudinal axis, the second bushing being engageable to the guide body via the pair of notches of the second bushing such that the longitudinal axis of the second opening has a second orientation relative to the bone contact surface different than the first orientation,
- wherein the pair of notches of the respective first and second bushings are discontinuous with each other.
