BACKGROUND
Estimates of the prevalence of lumbar zygapophysial joint (Z joint) pain differ in the literature, as do case definitions for this condition. No studies have determined the prevalence of "pure" lumbar Z joint pain, defined as complete relief of pain following placebo-controlled diagnostic blocks.
OBJECTIVE
The objective of this study was to estimate the prevalence of "pure" lumbar Z joint pain.
METHODS
In a private practice setting, 206 patients with possible lumbar Z joint pain underwent controlled diagnostic blocks using one of two protocols: placebo-controlled comparative blocks and fully randomized, placebo-controlled, triple blocks.
RESULTS
In the combined sample, the prevalence of "pure" lumbar Z joint pain was 15% (10-20%).
CONCLUSIONS
The prevalence of "pure" lumbar Z joint pain is substantially and significantly less than most of the prevalence estimates of lumbar Z joint pain reported in the literature.
背景
文献中腰椎关节突关节（Z 关节）疼痛的患病率存在差异，这种病症的病例定义也存在差异。目前尚无研究确定“纯”腰椎 Z 关节疼痛的患病率，即通过安慰剂对照诊断阻滞完全缓解疼痛的患病率。
目的
本研究旨在评估“纯”腰椎 Z 关节疼痛的患病率。
方法
在私人诊所环境中，206 例可能患有腰椎 Z 关节疼痛的患者接受了两种方案之一的控制诊断阻滞：安慰剂对照比较阻滞和完全随机、安慰剂对照、三联阻滞。
结果
在合并样本中，“纯”腰椎 Z 关节疼痛的患病率为 15%（10%-20%）。
结论
“纯”腰椎 Z 关节疼痛的患病率明显低于文献中报告的大多数腰椎 Z 关节疼痛患病率估计值。
