Abstract

There is disclosed a method of balancing a joint during a surgical procedure, to both maximize the range of motion of the joint and to reduce the likelihood of follow-up procedures. The method includes outputting a signal including a first data set associated with at least one of a force, a position, a displacement or a rotation associated with an apparatus disposed between a first bony structure and a second bony structure, the apparatus including a first portion configured to be coupled to the first bony structure, a second portion configured to be disposed between the first portion and the second bony structure, and a transducer and an actuator disposed between the first portion and the second portion. The method additionally includes outputting a signal including a second data set, the second data set associated with at least one of a force, a position, a displacement or a rotation associated with the apparatus after the performance of at least a part of a surgical procedure, the surgical procedure based at least in part on a recommendation based on the first data set.

Claims

1. A method of balancing a joint, comprising:

outputting a signal including a first data set associated with at least one of a force, a position, a displacement or a rotation associated with an apparatus disposed between a first bony structure and a second bony structure, the apparatus including a first portion configured to be coupled to the first bony structure, a second portion configured to be disposed between the first portion and the second bony structure, and a transducer and an actuator disposed between the first portion and the second portion;

outputting a signal including a second data set, the second data set associated with at least one of a force, a position, a displacement or a rotation associated with the apparatus after the performance of at least a part of a surgical procedure, the surgical procedure based at least in part on a recommendation based on the first data set; and

moving in response to a received signal a movable portion of an actuator, the movable portion of the actuator causing one of the first and second portion of the apparatus to move with respect to the other of the first and second portion of the apparatus.

2. The method of claim 1, wherein the outputting the signal includes outputting a plurality of signals while the first bony structure is moved through a full range of motion with respect to the second bony structure.

3. The method of claim 1, wherein the surgical procedure is associated with one of modifying a connective tissue or an angle of a bone cut.

4. The method of claim 1, wherein the signal including the first data set is output when a pressure measurement is above a predetermined threshold.

5. The method of claim 1, the transducer being one transducer from a plurality of transducers, the first portion of the apparatus being substantially parallel to the second portion of the apparatus, the method further comprising:

measuring a force associated with each transducer from the plurality of transducers;

comparing the force associated with each transducer from the plurality of transducers to the force associated with at least one other transducer from the plurality of transducers.

6. The method of claim 1, wherein the first bony structure and the second bony structure include one of (1) a portion of a tibia and a portion of a femur, (2) a portion of a humerus and a portion of a scapula, (3) a portion of a femur and a portion of a pelvis, (4) a portion of a vertebra and a portion of an adjacent vertebra, (5) a portion of a humerus and a portion of an ulna, and (6) a portion of a tibia and a portion of a talus.
