ANALYSIS OF LUMBO-SACRAL DISC PROLAPSE NEUROSURGICAL INTERVENTION
Background: Low back pain is a common cause of pain and there are many causes. Finding the exact cause of the pain can help guide treatment and management.
Objective: To evaluate the clinical presentation, diagnosis and surgical outcome of the treated patients with lumbar-disc prolapse.
Patients and Methods: Patients selection done using neuroimagings like plain radiographs and MRI Scan of lumbosacral spine. The surgical procedures applied were laminectomy, foraminatomy and evacuation of herniated disc material. Patients were analyzed postoperatively for outcome according to the symptoms resolved after surgery, objective clinical examinations and imaging studies.
Results: Fifty five patients, 25 (45%) males and 30 (55%) females. Predominant clinical presentation were low back pain with radiation to leg 36(65.4%), neurogenic claudication in 15 patients (27%), and neurological deficit (foot drop) 4 about (7.2%). Seventy four percent (about 41) of the herniated disc were found at L4 L5 and L5 SI levels. Rate of complications were 12.7% (about 7) with 4 cases infections and 3 with dural tear repaired intraopertively being commonest. Excellent to good surgical outcome were found in 90% (about 50) of the cases.
Conclusion: The results of the study depend mainly on selection of patients. Traditional laminectomy and discectomy still play a benefit for major group of patients. Foraminatomy, opening of roots foramen adds a benefit for the results.
