Abstract:
A device for aligning a surgical instrument in connection with one compartment knee-joint replacements, comprising:A) first and second support members (12;5), said first support member having a first support surface (3) and said second support member having a second support surface (6), each of said support surfaces (3;6) being adapted to bear against one condyle (24;25) of a femur (21); B) at least one rod-like transverse coupler (10;11) arranged parallel to a transverse axis (2) that intersects both condyles (24;25), said at least one rod-like transverse coupler having an end portion that is connected to the first support member (12) and releasably connectable to the second support member (5), wherein the transverse axis (2) extends parallel to a plane (1); and C) at least one guide template (20), the guide template (20) being displaceable parallel to the plane (1) relative to the second support member (5) and releasably lockable thereon via a positioning means (26); and wherein D) the second support member (5) is secured against rotation about the transverse axis (2) while being displaceable coaxially with the transverse axis (2) on the at least one transverse coupler (10;12) and releasably lockable thereon.
