The authors present a prospective study of quality of life (SF-36) and MRI findings in patients with low back pain (LBP). Disc herniation and nerve root compression contribute to LBP and poor quality of life. However, significant proportions of asymptomatic subjects have disc herniation and neural compromise. ⋯ Patients with neural impingement had improved pain scores at 6 months (P < 0.05). The study results showed that the pain and dysfunction caused by disc herniation and neural compromise are not sufficiently distinct from other causes of back pain to be distinguished by the SF-36. Whilst neural compromise may be the best radiological feature distinguishing patients who may benefit from intervention, it cannot predict quality of life deficits in the diffuse group of patients with LBP.

The purpose of the study was to evaluate the efficiency of patient-controlled analgesia (PCA) combined with continuous epidural block in patients who underwent lumbar spine surgery. In group 1 (postoperative PCA group), 23 patients were administered postoperative continuous epidural block in combination with analgesics, which was self-regulated by the patient using a device. In contrast, the 22 patients in group 2 (control group) received suppositories or intramuscular injections of analgesics on request. ⋯ The time spent by nurses on pain management in group 1 was less than that in group 2. No patient had any serious complications in either group. In conclusion, the present patient-controlled method combined with postoperative continuous epidural block could decrease the intensity of postoperative pain and the amount of time spent by nurses on the administration of postoperative analgesics after lumbar spine surgery.

Halm-Zielke instrumentation (HZI) was developed to eliminate the disadvantages of Zielke instrumentation (VDS) in terms of lack of primary stability and a kyphogenic effect. HZI is an anterior double-rod system. The system is composed of a lid-plate, which is fixed at the lateral aspect of the vertebral body with two screws, a sunk screw anteriorly and a VDS screw posteriorly. ⋯ All patients were treated without any additional external immobilization. In our opinion, HZI is a major improvement on the original Zielke VDS. It eliminates the kyphogenic effect and provides primary stability.
