Actuated positioning device for arthroplasty and methods of use

Abstract

A joint balancing insert with sensors and an actuated mechanism is disclosed. The joint balancing insert is used to balance a joint during arthroplasty surgery, as the sensors provide force, position and angular data relating to the movement of the joint, while the actuated mechanism allows for highly accurate and dynamic adjustments of the joint based on the data from the sensors. Various configurations of actuated mechanisms and sensors may be implemented in the insert to provide for manual or real time control of the insert, and customized interfaces are provided for visualized feedback of adjustments. Sensor data may also be collected and compared with expected or preferred data sets to provide adjustment recommendations and achieve better outcomes based on historical data.

1 .- 24 . (canceled) 
     
     
         25 . An device, comprising:
 a first plate configured to interface with a first bone structure of a joint;   a second plate configured to interface with a second bone structure of the joint, wherein the second bone structure is opposite the first bone structure;   at least one actuator disposed between the first plate and the second plate,
 wherein the at least one actuator is configured to apply a distraction force to the first plate and the second plate so as to distract the first bone structure from one another, and 
 wherein the force is configured to balance the joint while the joint is moved through a range of motion including at least one of flexion or extension; 
   at least one sensor coupled to at least one of the first plate or the second plate, wherein the at least one sensor is configured to capture data indicative of one or more sensors configured to provide data indicative of at least one of a force or a location; and   a processor communicatively coupled to at least one sensor,
 wherein the processor is configured (i) to receive the data from the at least one sensor, (ii) to determine data indicative of a balance of the joint, and (iii) to output the data indicative of the balance of the joint to a user.
