Abstract
The present invention enables a physician to distract a previously created opening, determine the size of the opening, and alternatively, subsequently assist in inserting an implant between adjacent spinous processes. The distracting device has two prongs which separate as the handle of the device is closed. When the spinous processes are distracted to a desired diameter, the physician can lock the prongs in place, allowing him to determine and select an appropriately sized implant.
