Abstract
An orthopedic distraction device is provided. The orthopedic distraction device includes a first upper paddle for engaging a first bone of a joint, a lower paddle for engaging a second bone of the joint and a displacement mechanism. The displacement mechanism includes a drive assembly operable to move the upper paddle relative to the lower paddle. The lower paddle is releasably connected to the displacement mechanism.
Claims21
A computer-assisted orthopedic surgery system comprising:
- an orthopedic distraction device that includes:
- an upper paddle for engaging a first bone of a joint,
- a lower paddle for engaging a second bone of the joint,
- an actuator assembly operatively engaged with the upper and lower paddles, and
- a controller operatively in communication with the actuator assembly to displace the upper paddle from the lower paddle by applying a predetermined load force, and determine an amount of displacement between the upper and lower paddles as the joint is moved through a range of motion when the predetermined load force is applied;
- and
- a computer operatively in communication with the orthopedic distraction device, the computer including:
- a display, and
- a processor configured to display, on the display, a gap spacing based upon the amount of displacement between the upper and lower paddles as the joint is moved through the range of motion.

- a lower paddle for engaging a second bone of the joint,
- an actuator assembly operatively engaged with the upper and lower paddles, and
- a controller operatively in communication with the actuator assembly to displace the upper paddle from the lower paddle by applying a predetermined gap spacing, and determine an amount of force acting on the upper and lower paddles as the joint is moved through a range of motion when the predetermined gap spacing is applied;
- and
- a computer that includes:
- a display, and
- a processor configured to display, on the display, a force profile based upon the determined amount of force acting on the upper and lower paddles as the joint is moved through the range of motion.
A computer-assisted orthopedic surgery system comprising:
- an orthopedic distraction device that includes:
- an upper paddle for engaging a first bone of a joint,
- a lower paddle for engaging a second bone of the joint,
- an actuator assembly operatively engaged with the upper and lower paddles, and
- a controller operatively in communication with the actuator assembly to displace the upper paddle from the lower paddle by applying a predetermined load force;
- a three-dimensional tracking system operatively in communication with the orthopedic distraction device for tracking positions of the upper and lower paddles, and reference markers for tracking positions of the first or second bones;
- and
- a computer operatively in communication with the three-dimensional tracking system, the computer including:
- a display, and
- a processor configured to
- determine an amount of displacement between the upper and lower paddles as the joint is moved through a range of motion when the predetermined load force is applied, or between the first and second bones of the joint, and
- display, on the display, a gap spacing based upon the determined amount of displacement between the upper and lower paddles or the first and second bones of the joint, as the joint is moved through the range of motion.
