Abstract:
A trial implant instrument for determining the space between adjacent spinous process, the instrument comprising:a sizer having a first end and a second end, whereas the first end forms a tip allowing the sizer to be easily inserted between adjacent spinous process, and the second end contains flanges extending therefrom to prevent the sizer from penetrating beyond a specific depth, and further contains a track to limit the rotation of the sizer; an elongated body having a first end and a second end, whereas the first end contains a handle portion so that a physician can urge the sizer between adjacent spinous process, and further whereas the second end contains a track pin and a mounting pin extending therefrom; and whereby the second end of the sizer is connected with the second end of the elongated body, so that once the sizer is inserted between adjacent spinous process, a physician may rotate the elongated body through a range of motion and not place any torsional forces upon the sizer.
