A variety of tests are currently used in an attempt to predict pain relief following arthrodesis of the lumbar and lumbosacral spine. External spinal skeletal fixation provides a means by which specific spinal motion units can be rigidly immobilized. A trial of temporary external fixation was investigated for its value in predicting the outcome of surgical fusion. Thirty-five patients with chronic low-back pain have been prospectively studied. The results show a statistically significant superiority of temporary external spinal fixation in predicting surgical result as compared with plain radiographs, discograms and facet blocks.
目前使用了各种测试方法，试图预测腰椎和腰骶椎融合术后的疼痛缓解情况。外部脊柱骨骼固定提供了一种可以将特定脊柱运动单元牢固固定的方法。对临时外固定试验在预测手术融合结果方面的价值进行了研究。对35例慢性下腰痛患者进行了前瞻性研究。结果显示，与普通X线片、椎间盘造影和小关节阻滞相比，临时外部脊柱固定在预测手术结果方面具有统计学上的显著优势。
