title: Percutaneous lumbosacral fixation and fusion: anatomic study and two-year experience with a new method.
abstract: This anatomic and clinical study describes a transsacral, percutaneous approach for fixation and fusion of the L5-S1 disc. A tunnel is created into the L5-S1 disc from this approach, permitting disc removal, bone grafting, and placement of two nine-millimeter diameter titanium screws into the body of L5. There were no complications referable to screw placement, and eight of nine patients had successful fusion.
