System and method for orthopedic distraction and stabilization

摘要

At least one embodiment is directed to a dynamic distractor (1 00) for distracting bones of a muscular-skeletal system. The dynamic distractor (100) includes at least one sensor (108, 110) which can provide loading, loading differential and position information as well as other measured parameters, a handle (112, 804), a lift mechanism (302), and one or more alignment aid (502, 802). The position and measurement sensors (108, 110) communicate with the processing unit (406) to display, process, and store measured data. A rod (604) couples a cutting block (602) to the distractor (100). The rod (604) also fixes a position of a cutting block (602) in relation to the distractor (100). The cutting block (602) is coupled to the distractor (100) to stabilize and align the muscular-skeletal system while shaping a bone.

主权项

1. An orthopedic system comprising:
a spacer having a superior surface and an inferior surface for coupling between at least two bones of a muscular-skeletal system; a handle coupled to the spacer; a cutting block; and a rod directly connected to the handle, where the rod is coupled to the cutting block to stabilize and align the cutting block; where the handle has a predetermined alignment to a surface of one of the at least two bones of the muscular-skeletal system and where the surface is aligned to a mechanical axis of the muscular-skeletal system; further including an alignment tool coupled to the handle to measure misalignment of the surface to the mechanical axis; where the alignment tool comprises at least one laser coupled to the handle; and at least one target coupled to the muscular-skeletal system where the target is positioned to be in alignment with the mechanical axis and where a beam of the laser hits the target to measure the misalignment of the surface to the mechanical axis.
