Abstract
A method for intraoperatively measuring joint contact mechanics of a patient's joint is provided. The method includes inserting a sensor between first and second bones of a joint. Then a predetermined force is applied to one of the first and second bones. Afterwards, contact mechanics such as, contact stresses, contact areas and/or forces are measured between the first and second bones in response to the applied predetermined force.
Claims19
A method for intraoperatively measuring joint contact mechanics of a patient's joint comprising:
- inserting a sensor between first and second bones of a joint;
- applying a predetermined force to one of the first and second bones;
- and
- measuring contact mechanics between the first and second bones in response to the applied predetermined force.
A system for intraoperatively measuring joint contact mechanics of a patient's joint comprising:
- a sensor for measuring joint contact stresses between first and second bones of the joint;
- a load cell for measuring forces applied to one of the first and second bones;
- and
- a computer operatively in communication with the sensor and configured to record contact mechanics measured by the sensor upon application of forces to one of the first and second bones.
