ABSTRACT:
A method and a device for positioning a cutting guide for cutting a bone such as the tibia has a first elongated member having a longitudinally extended threaded surface. A second member is provided for receiving the first member. The second member includes an adjustment element mounted for rotation on the second member and for movement transverse to a longitudinal axis of the first member. The adjustment element has a threaded surface selectively engageable with the first member threaded surface. A biasing element extends between the second member and the adjustment element for biasing the adjustment element into engagement with the threaded outer surface of the first member so that rotation of the adjustment element causes relative movement between the first and second members. The adjustment element is moveable against the biasing element in the transverse direction out of engagement with the first member. Thus, the device allows both free sliding and threaded adjustment along the axis.
