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.
Claims20
A method of planning an arthroplasty procedure of a joint comprising:
- attaching an orthopedic distraction device to a first bone of a joint before any bone resections of the first bone or a second bone of the joint, the orthopedic distraction device including:
- an upper paddle for engaging the second bone, and
- a displacement mechanism operable to displace the upper paddle relative to the first bone;
- using the orthopedic distraction device, applying a displacement force to displace the upper paddle from the first bone, and measuring a gap spacing between the first and second bones of the joint upon applying the displacement force;
- and
- planning a bone resection of one of the first and second bones of the joint based on the measured gap spacing between the first and second bones of the joint.
A method of performing an arthroplasty procedure of a joint using a computer aided orthopedic surgery system that includes an orthopedic distraction device, a three-dimensional position tracking system, and a computer operatively in communication with the orthopedic distraction device and the three-dimensional position tracking system, comprising:
- attaching the orthopedic distraction device to a first bone of a joint before any bone resections of the first bone or a second bone of the joint, the orthopedic distraction device including:
- an upper paddle for engaging the second bone, and
- a displacement mechanism operable to displace the upper paddle relative to the first bone;
- using the orthopedic distraction device, applying a displacement force to displace the upper paddle from the first bone;
- using the three-dimensional position tracking system, determining a relative position of the first bone and the second bone upon application of the displacement force;
- and
- using the computer, determining a predicted gap between the first and second bones of the joint based on the relative position of the first bone and the second bone.
