SYSTEM AND METHOD FOR SOFT TISSUE TENSIONING IN EXTENSION AND FLEXION
First Claim
1. A method of distracting two surfaces of the muscular-skeletal system comprising:
- placing a spacer between two surfaces of the muscular-skeletal system where the two surfaces are in a first relational position; and
positioning the two surfaces of the muscular-skeletal system in a second relational with the spacer in place.

Abstract
At least one embodiment is directed to a dynamic distractor (100) for distracting bones of a muscular-skeletal system. The dynamic distractor (100) comprises at least one sensor (108, 110), a handle (112, 804), a lift mechanism (302), and one or more alignment aids (502, 802). The position and measurement sensors (108, 110) are in communication with the processing unit (406) to display, process, and store measured data. The process of distraction separates two components such as bones of the muscular-skeletal system. A gap created by dynamic distractor (100) is adjustable under load. The at least one sensor (108, 110) can provide loading, loading differential, and position information as well as other measured parameters. Dynamic distractor (100) can aid in the alignment of the skeletal systems and to verify that alignment is correct. Soft tissue release can be performed with dynamic distractor (100) in place over a full range of motion.

9. A method of distracting two surfaces of the muscular-skeletal system comprising:
-
placing a first and second support structure of a distractor between two surfaces of the muscular-skeletal system; changing a gap between the first and second support structures with the two surfaces of the muscular-skeletal system in a first relational position measuring at least one parameter of the muscular-skeletal system with a sensor coupled to the distractor in the first relational position; changing the at least one parameter through modification of the muscular-skeletal system; and positioning the two surfaces in a second relation position while the distractor remains in place. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of distracting a knee joint of a leg comprising the steps of:
-
distracting a joint of the muscular-skeletal with a spacer where surfaces of the joint are in a first relational position; performing soft tissue release on the muscular-skeletal system with the spacer in place to adjust joint loading; and moving the surfaces of the joint in a second relational position with the spacer in place. - View Dependent Claims (16, 17, 18, 19, 20, 21)
