This was a cross-sectional analytic study.
In relation to pain from the sacroiliac joint, this study sought to establish 1) its prevalence, 2) the validity of pain provocation, 3) whether any arthrographic abnormalities predict a response to joint block, and 4) whether certain pain patterns discriminate patients with this diagnosis.
The true prevalence of sacroiliac joint pain is unknown and despite a plethora of clinical tests, none of these tests has been validated against an established criterion standard. To our knowledge, arthrography of the sacroiliac joint had never been studied.
Forty-three consecutive patients with chronic low back pain maximal below L5-S1 were investigated with sacroiliac joint blocks under image intensifier using radiographic contrast followed by 2% lignocaine. Information was obtained on pain provocation, analgesia, and image pattern.
Thirteen patients (30%) obtained gratifying relief of their pain. Nine of these also exhibited tears of their ventral capsule. Groin pain was the only pain referral pattern found to be associated with response to sacroiliac joint block.
The sacroiliac joint is a significant source of pain in patients with chronic low back pain and warrants further study.
这是一项横断面分析研究。
关于骶髂关节疼痛，本研究旨在确定1）其患病率，2）疼痛激发试验的有效性，3）关节造影异常是否可预测对关节阻滞的反应，以及4）某些疼痛模式是否能鉴别出患有该疾病的患者。
骶髂关节疼痛的真实患病率尚不清楚，尽管有大量临床检查，但这些检查均未依据既定的标准进行验证。据我们所知，骶髂关节造影从未被研究过。
对43例连续的慢性下腰痛（疼痛最严重部位在L5-S1以下）患者，在影像增强器引导下使用放射造影剂，随后注射2%利多卡因进行骶髂关节阻滞。获取有关疼痛激发试验、镇痛效果和影像表现的信息。
13例患者（30%）疼痛得到显著缓解。其中9例患者还存在腹侧关节囊撕裂。腹股沟疼痛是唯一被发现与骶髂关节阻滞反应相关的疼痛放射模式。
骶髂关节是慢性下腰痛患者疼痛的重要来源，值得进一步研究。
