[ results of pedicular internal fixation of lumbar spine in patients hospitalized at the neurosurgery wards of MUMS [1996-2001]]

Objective: In order to evaluate the usefulness of the pedicular screw in various lumbar spine disorders, we observed all patients that consecutively underwent transpedicular instrumentation in neurosurgery wards

Methods and Materials: A total of 125 patients [76 men and 69 women], ranging between the ages of 12 to 72 years, underwent lumbar stabilizing instrumentation with 3 types of pedicular screw systems between September 1996 and August 2001. Clinical records and follow up notes were reviewed and data was analyzed with T-Student and Person Test

Results: During the study, 652 pedicular screws were inserted with a rate of precise insertion being 96% at the first attempt. Bony fixation was achieved in 82% of patients at meantime of 4 to 5 months of follow up after surgery. Early complications had occurred in 13.4% of patients during their hospitalization and late complications after treatment were 5.6%. Mortalities were not seen during the hospitalization

Conclusion: This surgical technique for stabilization of lumbar region in various disorders of spine provides a highly successful rate of arthrodesis with an acceptable rate of complications
