In this study we attempted to explore the correlation between lumbar disc herniation and functional disorders of the lumbar spine. Fifty patients with lumbar disc herniation proven by computed tomography underwent a comprehensive functional, neurological and radiological examination. All patients were compared to a control group consisting of 16 healthy subjects of comparable age. ⋯ Segmental dysfunction is explained by increased muscular tone being provoked by irritation of the sinuvertebral nerve. The differences between L4-5 and L5-S1 movements are probably due to the different functional anatomy of these segments. Ligamental pain may be explained by the fact that these ligaments have the same insertion and the muscles have increased in tone.

Intravenous administration of local anaesthetics has repeatedly been recommended for the treatment of chronic pain. Some authors have also reported on their use in postoperative pain management. However, most of these publications are case reports or refer to rather old studies or investigations based on study designs that fail to meet present scientific standards. ⋯ During the first 24 h after surgery 12 patients in the lidocaine group required a total of 550 mg meperidine in addition, while 8 patients in the control group required a total of 300 mg meperidine. The postoperative meperidine consumption was not significantly diffent between the lidocaine group and the control group. Intravenous lidocaine infusion did not significantly reduce postoperative pain after tonsillectomy in the dosage used.
