M. Macmillan et al., PERCUTANEOUS LUMBOSACRAL FIXATION AND FUSION - ANATOMIC STUDY AND 2-YEAR EXPERIENCE WITH A NEW METHOD, Neurosurgery clinics of North America, 7(1), 1996, pp. 99
This anatomic and clinical study describes a transsacral, percutaneous
approach for fixation and fusion of the L5-S1 disc. A tunnel is creat
ed into the L5-S1 disc from this approach, permitting disc removal, bo
ne grafting, and placement of two nine-millimeter diameter titanium sc
rews into the body of L5. There were no complications referable to scr
ew placement, and eight of nine patients had successful fusion.
