Abstract
Introduction: High grade spondylolisthesis is surgically challenging problem, inspite its distinct minority aproximally 4-8% in most series, the problem is a source of ongoing debate about the optimum surgical treatment.
Aim of the Work: The aim of this study to evaluate the clinical and radiological outcome in total of 27 patients with high grade spondylolisthesis treated by instrumented posterior fusion using reduction pedicle screw system.
Material and Methods: A total of 27 patients with high grade spondylolisthesis (grade III, IV), had been surgically treated during the period from January 2009 and December 2011 the average follow-up with (16±2 months) 7 patients lost follow-up 6 months following surgical intervention. 12 out of 27 patients developed post-operative complication with was transit in the form of CSF leak in 6 patients and radicular pain in 4 patients and two patients developed new neurological deficit with was permanent. The clinical outcome was excellent in 24 patients 2 patient had good outcome and one patient had poor outcome.
Conclusion: Posterior lumbar instrumented fusion using reduction pedicular screw system is good surgical option in treating high grade spondylolisthesis, however long term outcome could enlighten more details about the validity of this system to treat such challenging problem.
