Frozen cadaver specimens from three dogs were used to create a sectional anatomic atlas of the sacroiliac region. Frozen/thawed cadaver specimens from 12 dogs were used to develop an ultrasound-guided sacroiliac joint injection technique. Accuracy of the technique was tested in 15 additional canine cadaver specimens, using injectate containing blue dye and iodinated contrast medium. Sonoanatomic landmarks for consistently identifying a caudodorsal window into the canine sacroiliac joint space included the L7-S1 articular process joints, ilial wing, sacral wing, sacral lamina, and median sacral crest. Accuracy of ultrasound-guided sacroiliac joint injection was not significantly affected by operator, but was affected by the tissue location targeted and the reference standard used for calculations. Accuracy of the technique was good for placing injectate into either the synchondrosis component, dorsal sacroiliac ligament or ventral sacroiliac ligament; fair to poor for placing injectate into the synovial component; and poor for placing injectate into all four sacroiliac soft tissue structures. Concurrent placement of injectate into extraarticular tissues occurred frequently. We conclude that ultrasound-guided sacroiliac joint injection is feasible for evaluation as a treatment method for lumbosacral region pain in dogs, but is not sufficiently accurate for localizing pain to the sacroiliac joint alone.
使用来自三只犬的冷冻尸体标本制作了骶髂区域的断层解剖图谱。使用来自12只犬的冷冻/解冻尸体标本开发了一种超声引导下的骶髂关节注射技术。在另外15个犬类尸体标本中使用含有蓝色染料和碘化造影剂的注射液测试了该技术的准确性。用于持续识别进入犬骶髂关节间隙的尾背侧窗口的超声解剖标志包括L7-S1关节突关节、髂翼、骶翼、骶骨板和骶中嵴。超声引导下骶髂关节注射的准确性不受操作者的显著影响,但受靶向组织位置和用于计算的参考标准的影响。该技术在将注射液注入软骨结合部、骶髂背侧韧带或骶髂腹侧韧带时准确性良好;在将注射液注入滑膜成分时准确性一般至较差;在将注射液注入所有四个骶髂软组织结构时准确性较差。注射液经常同时注入关节外组织。我们得出结论,超声引导下的骶髂关节注射作为犬腰骶部疼痛的一种治疗方法进行评估是可行的,但对于单独将疼痛定位到骶髂关节来说不够准确。
