<p>The present invention enables a physician to distract a previously created opening, determine the size of the opening, and assist in inserting an implant between two adjacent vertebrae. The distracting device has two prongs (102, 104) which separate as the handle (106) of the device (100) is closed. When the vertebrae are distracted to a desired diameter, the physician can lock the prongs (102, 104) in place, allowing him to determine and select an appropriately sized implant.</p> |
