Comparative Study
Low back pain and lifestyle. Part II--Obesity. Information from a population-based sample of 29,424 twin subjects.
A cross-sectional postal survey of 29,424 twin subjects aged 12-41 years obtained from a population-generated panel. ⋯ Obesity is modestly positively associated with low back pain, in particular with chronic or recurrent low back pain. However, because the association is weak, because there is no consistent positive monotonic dose response, and because the link disappears in monozygotic twins who are dissimilar in body mass index, it is unlikely that this association is causal. It is possible, however, that obesity plays a part in the chronicity of simple low back pain. Therefore, those with recurring or long-term low back pain deserve further attention.

Comparative Study
Contralateral recurrent lumbar disc herniation. Results of discectomy compared with those in primary herniation.
The surgical outcomes of patients who underwent discectomy for contralateral recurrent herniation and primary herniation were evaluated. ⋯ Clinical results in patients reoperated on for contralateral recurrent lumbar disc herniation compare favorably with those reported after primary discectomy. The improvement of pain in the low back and lower limbs reported by the majority of patients 2 years after reoperation suggests that fusion is not needed in this patient population.

Comparative Study
Anterior interbody fusion versus posterolateral fusion with transpedicular fixation for isthmic spondylolisthesis in adults. A comparison of clinical results.
Clinical and radiographic results were assessed in adult patients who had undergone operation for isthmic spondylolisthesis. ⋯ There was no statistically significant difference in clinical results between anterior interbody fusion and posterolateral fusion with transpedicular fixation for the treatment of isthmic spondylolisthesis in adults (P < 0.05).

Comparative Study
One-stage decompression and posterolateral and interbody fusion for severe spondylolisthesis. An analysis of 14 patients.
A retrospective study of 14 patients with high-grade L5-S1 spondylolisthesis surgically treated with one-stage decompression and posterolateral and interbody fusion (technique of Bohlman and Cook). ⋯ Posterior decompression of the spinal canal combined with anterior and posterior arthrodesis performed at one stage through a posterior approach is a safe and effective technique for managing severe spondylolisthesis.

An analysis of the geometric data of the lumbar spine in Chinese men. Lateral radiographs were obtained of 16 men in the upright position to a trunk flexion of 90 degrees in 30 degrees increments. ⋯ No obvious interracial differences were found in the geometric data found in this study, which suggests that morphometric data obtained from Caucasian individuals may be applied to Chinese patients for clinical purposes.
