Sacroiliac Joint Steroid Injection
骶髂关节激素注射
A sacroiliac joint injection is designed to diagnose and treat pain and inflammation from sacroiliac joint dysfunction.
骶髂关节注射用于诊断和治疗的骶髂关节功能紊乱引起的疼痛和炎症。
Either too much or too little movement in one of the sacroiliac joints, which are located at the bottom of the spine on each side of the sacrum, can cause lower back pain and/or leg pain.
骶髂关节位于脊柱底部骶骨的两侧，无论活动过多还是活动过少，都会引起腰痛和/或腿痛。
An injection in the sacroiliac joint usually has two goals: to confirm the sacroiliac joint as the source of the pain, and to alleviate that pain.
骶髂关节注射通常有两个目的：首先是确定骶髂关节是不是疼痛的来源，其次是减轻疼痛。
The procedure begins with the patient lying on his or her stomach. The area around the sacroiliac joint is numbed with an injection of a local anesthetic.
准备注射时，患者取俯卧位，骶髂关节周围的区域注射局部麻醉药物进行麻醉。
Then, using fluoroscopy dye and X-rays to assist in guiding the injection, a needle is inserted into the sacroiliac joint to deliver medicine directly to the source of pain.
然后，用造影剂和X线透视来引导注射。在骶髂关节内插入穿刺针，将药物直接注射到引起疼痛的部位。
The medication injected into the joint can be a local anesthetic, such as lidocaine or bupivacaine, and may also include an anti-inflammatory medication, such as a corticosteroid. If the local anesthetic provides immediate pain relief, it diagnoses the sacroiliac joint as the source of the patient’s pain.
注射到关节内的药物包括局麻药（比如利多卡因或布比卡因），还可包括抗炎药物，比如糖皮质激素。如果局部麻醉药使疼痛即刻缓解，可以诊断骶髂关节就是疼痛疼痛的来源。
The anti-inflammatory steroid may relieve pain in the sacroiliac joint over a longer period of time, possibly for weeks or months, allowing the patient to pursue physical therapy.
抗炎的激素能长时间缓解骶髂关节的疼痛，往往长达数周或数月，使病人能接受物理治疗。
