Sciatica is a common syndrome mostly affecting adults. It has a wide range of etiologies, classified into intra- and extra-spinal, with intra-spinal being the most common, usually due to lumbar disc herniation causing nerve root compression. Sacroiliac (SI) joint pathologies are a known cause of extra-spinal sciatica syndrome, following multiple possible mechanisms. We report a case of a 33-year-old female patient who presented for non-resolving sciatica symptoms, found to have an inferior SI joint osteophyte compressing the sciatic nerve, who underwent surgical excision due to failure of conservative measures. All causes of sciatica related pain should be subjected to further investigations if not attributed clinically and radiologically to intra-spinal etiologies. SI joint imaging play an important role in the diagnosis of SI joint related sciatica, with the gold standard being an intra-articular anesthetic injection, to monitor for symptom relief in order to confirm the diagnosis, and choose the optimal treatment modality.

Sa关节骨赘压迫一名年轻患者的坐骨神经导致无法解决的坐骨神经痛：一例病例并文献复习

坐骨神经痛是一种常见的综合征，主要影响成年人。它的病因范围很广，分为椎内和椎外，其中椎内最常见，通常是由于腰椎间盘突出症引起神经根受压。cro关节病是多种可能的机制，是脊柱外坐骨神经痛综合征的已知病因。我们报告了一名33岁女性患者的病例，该患者因无法解决的坐骨神经痛症状而被发现，其SI关节骨赘较压迫坐骨神经差，由于保守措施的失败，他们接受了手术切除。如果临床上和放射学上并非归因于脊柱内病因，则所有导致坐骨神经痛相关疼痛的原因都应接受进一步研究。
