Abstract
Systems and methods for joint replacement are provided. The systems and methods include a surgical orientation device and at least one orthopedic fixture. The surgical orientation device and orthopedic fixtures can be used to locate the orientation of an axis in the body, to adjust an orientation of a cutting plane or planes along a bony surface, to distract a joint, or to otherwise assist in an orthopedic procedure or procedures.
Claims20
A system comprising:
- a knee distraction device, comprising:
- a tibial component comprising a tibial paddle, wherein the tibial paddle is configured to be inserted into a knee joint;
- a femoral component comprising a femoral paddle, wherein the femoral paddle is configured to be inserted into the knee joint;
- at least one adjustment device configured allow at least one degree of freedom between the tibial paddle and the femoral paddle;
- and
- a portable surgical orientation device comprising:
- a housing,
- at least one inertial sensor, and
- wherein the surgical orientation device is configured to provide an indication of tension within soft tissue on a medial side and/or a lateral side of the knee joint.
6 more elements
A system comprising:
- a knee distraction device, comprising:
- a tibial component comprising a tibial paddle, wherein the tibial paddle is configured to be seated on a tibia;
- a femoral component comprising a femoral paddle, wherein the femoral paddle is configured to be seated on a femur;
- at least one adjustment device configured allow at least one degree of freedom between the tibial paddle and the femoral paddle;
- and
- a portable surgical orientation device comprising:
- a housing,
- wherein a visual indication is provided to a user of a first gap between one femoral condyle and a tibial plateau and a second gap between the other femoral condyle and the tibial plateau.
5 more elements
A system comprising:
- a knee distraction device, comprising:
- a tibial component comprising a tibial paddle, wherein the tibial paddle is configured to be extramedullary to a tibia,
- a femoral component comprising a femoral paddle, wherein the femoral paddle is configured to be extramedullary to a femur;
- at least one adjustment device configured allow at least one degree of freedom between the tibial paddle and the femoral paddle;
- and
- a portable surgical orientation device comprising:
- a housing,
- at least one inertial sensor, and
- wherein the surgical orientation device is configured to display a varus-valgus angle.
