Abstract : Introduction: Although, the non operative treatment modalities of degenerative spondylolisthesis
remained relatively unchanged during the past two decades, the number of surgical options has increased
rapidly over the same period. The optimal surgical technique to treat symptomatic spondylolisthesis has
not been determined.
Materials and Methods: In this prospective, non-randomizedstudy, 56 patients of degenerative
spondylolisthesis who have failed to conservative treatment for a minimum period of 3 months
were subjected to surgery (decompressive laminectomyplus posterolateral instrumentation with pedicle
screwsplus intertransverse process arthrodesis with autologous bone graft) to compare the intensity of pain
and degree of disability pre-operatively and post operatively at six months follow up using self-administered
questionnaire and radiological assessment.
Results: The degree of spondylolisthesis was reduced post operatively (23.11% vs15.19%; p
on visual analogue scale was also reduced post operatively (7.52 0.68 vs 0.300.74; p
disabilities including paresthesia(16.1% vs 1.8%), hypoesthesia (48.2% vs 32.1%), weakness (48.2% vs
28.6%), stiffness(7.1% vs 0), and urinary symptoms (12.5% vs 1.8%) were also significantly (p
Cocnclusion: Surgical treatment including decompression,posterolateral fusion and arthrodesis offers a
great benefit in degenerative spondylolisthesis.
