Posterior lumbar interbody fusion is biomechanically a good procedure. Though recommended many years ago by Cloward, PLIF (posterior lumbar interbody fusion), was not widely used for many years. Recently, many authors have recognized PLIF as a preferred technique for lumbar stabilization. The use of this newfusion device provides immediate stabilization, preservation of discheight due to highly resistant material, and long term fusion with autogenous bone. Nine cases of posterior lumbar interbody fusion using this new fusion device were evaluated. Subjects included eight males and one female with a mean age of 49.3 years, ranging from twenty-four to seventy-four years. Diagnosis was degenerative spondylolisthesis in two cases, herniated disc disease in two, disc degeneration in three, degenerative lumbar scoliosis in two. Seven of nine cases achieved solid union, but union was delayed in three cases. If you select cases carefully, this implant is very useful because it acts as an interbody spacer with its own stabilizing capacity, without reguiring additional fixation.
