Lumbar disc operations have been performed in Brno since 1952 and from the very beginning they are performed under regional anaesthesia. Since 1965 until 1999 about 16,000 operations for herniated discs have been performed here. The number of operations doubled with the foundation of the second neurosurgical department in Brno in 1992. Lumbar disc surgery represents 25% of the operation spectrum in our department. Epidural anaesthesia is advantageous for less risk of some complications compared with general anaesthesia and enables communication between the surgeon and the patient. Other advantages are: less visible bleeding in the operative field due to the lateral position and the fact that the surgeon can sit during the operation. On a long-term basis we found 4-5% had further surgery for reccurent problems. Objective neurological evaluation 6 weeks after the operation showed improvement in 92% of patients. The patients themselves consider their status as very good or satisfactory in 82% (median 3 years after the operation). Besides a correctly performed operation we emphesize also the role of correct diagnosis (good correlation between the patient's problems and CT scan finding) for a good treatment result.
