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. |
