 Although posterior lumbar interbody fusion (PLIF) using threaded cages alone is a useful procedure in our experience, the rate of union achieved by this operation has not been very high. The Lumbar Alligator Spinal System (LA) is a clamping plate for the spinous processes that has been developed to provide supporting instrumentation for this procedure. Single-level posterior lumbar interbody fusion using the LA and BAK Proximity Cages was performed in 47 patients with degenerative spondylolisthesis. Mean age at the time of surgery was 66.0 years, and the follow-up period was more than 24 months (average:35.6 months). Solid union was defined as bony bridging between two vertebral bodies on plain radiograms. Solid union was achieved in 46 patients (97.9%) as of two years after surgery. The LA is a useful instrument for PLIF using threaded cages.
