Abstract: A knee joint balancing instrument. A first body includes a first paddle for engaging a proximal end of a tibial bone. A second body includes a second paddle for engaging a distal end of a femoral bone. A rack is attached to the first body and is moveable relative thereto in a superior-inferior direction. The second body is pivotally mounted to the rack for pivoting about an axis extending in an anterior-posterior direction. A ratchet is connected to the first body and to the rack for selectively restraining movement of the rack in the superior-inferior direction relative to the first body. A pinion is connected to the first body and engages the rack to cause movement of the rack in the superior-inferior direction relative to the first body.

Abstract: A dental articulator having an upper support member for supporting a dental cast and a lower support member for supporting a second dental cast. A polycentric hinge joint is provided for simulating the temporomandibular joint of a patient. The polycentric hinge joint comprises a fossae block secured to the upper support member and a condyle member secured to the lower support member which engages a fossae recess in the fossae block. A spring is provided for securing the lower support member to the upper support member and simulating the muscles used for mastication. A pair of wires are provided for simulating the ligaments of a patient. The upper end of each wire passes through an opening in the upper support member. The lower end of each wire is secured to the lower support member. A limiting block is provided on the upper end of each of the wires so as to restrict its movement.
