摘要： A method of resecting a proximal tibia and distal femur for implanting a partial knee prosthesis uses a resecting kit which includes multiple spacers, each of which has a different spacing dimension. A surgeon selects the appropriate spacer with the amount of correction desired to align the patient's leg and installs the spacer with the spacing dimension between the distal femur and proximal tibia which is to receive the partial knee prosthesis. The spacers have projecting stems, upon which a resector is installed. The resector is then aligned with the axis selected by the surgeon according to known methods, and is pinned to the femur and proximal tibia. A distal femoral cut is then made in the femur after which the resector is removed while leaving at least two of the pins in place, the pins being headless pins. A second resector is then installed on the pins to effect the required cut of the tibia. Additional cuts are made in the femur according to known procedures, and the femoral and tibial prostheses are then installed, according to known procedures.

摘要： A system and method for aligning a patient's leg, for establishing the ultimate alignment of the leg prior to making a horizontal femoral cut or a horizontal tibial cut, for preparing the distal femur for receiving a femoral implant, and for making the horizontal, femoral and tibial cuts. The system and method incorporate a spacer, a cutting guide, and a template. The spacer is insertable between a distal femur and a proximal tibia to rotate the tibia with respect to the femur into the desired alignment. The cutting guide is engageable with the spacer, and can be fixed to the proximal tibia and the distal femur. The cutting guide has openings sized and shaped to guide a surgical saw to make the horizontal femoral cut and the horizontal tibial cut. The template is shaped to closely conform with the distal femur to allow the leg to be extended and to allow the procedure to be performed without dislocating a patella. Through one method of the present invention, the practitioner can select the desired ultimate alignment of the leg prior to making the horizontal, tibial and femoral cuts. As a result, when a replacement knee is implanted, the leg will be in the desired alignment.

摘要： A method and apparatus for correcting limb alignment in a unicondylar knee arthroplasty and linking the distal femoral cut and the proximal tibial cut. Alignment rods are connected to a spacing apparatus to facilitate correction of limb alignment. The alignment rods are positioned along the mechanical axis of the femur and the tibia and the knee joint is positioned to correct alignment. A spacing apparatus is positioned in the relevant knee compartment and utilized to hold the knee in position to correct limb alignment. The spacing apparatus includes a femoral cut slot through which the distal femoral cut is made and further includes tibial affixment apertures through which a headless securing device can be positioned to secure the spacing apparatus to the tibia. After the distal femoral resection is complete, the spacing apparatus is removed, with the headless securing devices remaining positioned in the tibia. The headless securing devices are used as a reference for securing a tibial cut block to the tibia for making the proximal tibial resection. With the mechanism of the present invention, the knee can be placed in flexion when making the proximal tibial cut and the distal femoral cut is linked to the proximal tibial cut.

摘要： A provisional orthopedic prosthesis having a first provisional component and an optional second component. The provisional prosthesis may be a partial knee prosthesis and is used to assess the fit of a permanent prosthesis having first and second components. The first provisional component has a size which differs from the first permanent component and is mountable on a bone which has been only partially prepared to receive the first permanent component. Providing a provisional component which is mounted on a partially prepared bone, simplifies the preparation of the bone for a differently sized component if the provisional indicates that the preliminarily selected permanent component is incorrectly sized.
