Objectives: To evaluate the demographic characteristics, surgical safety in addition to highlighting major complications in 1525 consecutive patients who underwent microscopic inter-laminar discectomy electively at King Hussein Medical Center. Methods: A series of 1525 consecutive patients underwent elective inter-laminar lumbar discectomy, during a 5year period (January 2009 to January 2014) in our neurosurgical department, are analyzed retrospectively. Demographic features evaluated: Age, gender, site of surgery. In addition to general and specific complications encountered. Results: Lumbar discectomy surgeries operated more commonly in male patients constituted with a percent of 64 % of all lumbar discectomies considered in this study, and it was more common in the age group between 40-60 yearold patients .The most common level operated was L4/L5 level, followed by the L5/S1 level. With a recurrence rate of 4.9% in all over levels operated, unintended durotomy occurred in 7.9 % of the surgeries, superficial wound infection and deep wound infection occurred in 3%, 0.5% respectively and the mortality rate was 1/1525. Conclusion: Five-year follow-up demonstrate effective interlaminar approach in treatment of herniated lumber disc with comparable complications to reported incidences worldwide. Demographic features were in line with reported results in terms of gender and age groups and slit deference regarding level of disc herniation.
