What is Adjacent Segment Degeneration after Lumbosacral Fusion in Spondylolisthesis: A Retrospective Radiological and Clinical Analysis about?

## Purpose of the study: Whereas the posterior lumbar interbody fusion (plif) technique with pedicle screw fixation has shown satisfactory clinical results, solid fusion has been reported to accelerate degenerative changes at adjacent unfused levels, especially at the cranial level. the aim of this retrospective study was to evaluate a group of patients with adjacent segment disease (asd) developed after 360-degrees lumbar fusion for spondylolisthesis performed by plif with transpedicular fixation and posterolateral fusion (plf).radiographic examinations were focused on the origin or progression of degenerative changes at the adjacent segments after the operation, with statistical evaluation of some parameters. clinical evaluations included back pain or neurologic symptomatology which emerged later in the post-operative period in patients with adjacent segment degeneration. ## Material: The authors performed a retrospective analysis on a group of 91 patients (49 females, 42 males) with isthmic, degenerative or dysplastic spondylolisthesis at the l4-l5 level who had undergone the plif technique on l4/l5 or l5/s1 with transpedicular fixation surgery and plf in the period from 1990 to
