Abstract
Background: Lumbar disc herniation is one of the most frequently diagnosed causes of low back pain and is a common cause of radiculopathy. Lumbar discectomy is a common and widely accepted operation for lumbar disc herniation in most countries. However,several authors indicated that residual back pain and recurrent disc herniation were important factors affecting long-term results of discectomy alone. Methods of spinal arthrodesis continue to evolve, in efforts to treat back pain. What we are concerned with here is whether spinal fusion can settle these problems and attain a better and more durable outcome than discectomy alone. Objective:the aim of this study is to compare between the conventional discectomy and the discectomy with Interbody fusion and bilateral pedicular screw fixation in the management of single level lumbar disc herniation. Methods: This is a prospective study done on 50 patients (25 in each group) at Cairo University Hospitals in the period between October 2018 and June 2019 fulfilling the inclusion criteria. Diagnosis will be made clinically with history (low back pain, sciatica, {u2026}).Examination (motor power,straight leg raising test,{u2026})and radiological findings in MRI,CT and X-ray of lumbo-sacral spine. The pain status (VAS) will be pre- and postoperatively evaluated and followed up every three months for one year. Results: The study included 50 patients (25 in each group).Ages ranged from 13 to 60 years (mean 40.4 years old) with slight female predominance. The most common clinical findings presented at diagnosis were low backpain followed by lower limb pain in the form of claudication and sciatica. L5-S1 disc prolapse was the most common level affected in both groups followed by L4-5 level. Regarding the clinical outcome,there was statistical significance in the VAS of low back pain at 9 months and one-year follow-up favoring the fusion group with mean VAS 0.40 and 1.32 (p-value <0.05)
