<p>There is provided an insertion instrument (10) that has a first, partially hollow elongated member (12) and a second elongated member (30) that can be positioned relative to the first member. The two members can be locked together and dissociated from each other via a turnbuckle locking mechanism (45). Each member has a tine (18, 25) protruding at its distal end. When the two members are locked together, the two tines form a fork-like front end for holding an implant during insertion. One tine may be retracted to release the implant in a desired position. There is also provided a method for holding, accurately positioning and inserting the implant into an intervertebral space between adjacent vertebrae. There is further provided a mechanism and method for releasing the implant between adjacent vertebrae, and easily and safely removing the insertion instrument.</p> |
