This anatomic study was undertaken to describe a new posterior approach enabling direct inspection of reduction of sacroiliac joint disruption (SIJD), and guidance of iliosacral screw placement. The reduction of SIJD is usually monitored by inspection of the opposing sacrum and ilium at the posterior margin of the greater sciatic notch and there is a relative lack of information concerning inspection of reduction of SIJD from the posterosuperior aspect of the sacroiliac joint surface. Ten cadavers were dissected to determine the possibility of inspecting reduction of SIJD from the posterosuperior aspect of the sacroiliac joint by means of a posterior approach which passed immediately lateral to the deep back muscles and the fifth lumbar transverse process. The results indicated that the posterosuperior aspect of the sacroiliac joint surface and sacral ala can be directly palpated or visualised. This approach facilitates improved access for inspection of reduction of SIJD and guidance of iliosacral screw placement.
本解剖学研究旨在描述一种新的后路入路，该入路能够直接观察骶髂关节脱位（SIJD）的复位情况，并指导髂骶螺钉的置入。SIJD的复位通常通过在坐骨大切迹后缘检查相对的骶骨和髂骨来监测，而关于从骶髂关节面后上方检查SIJD复位情况的信息相对较少。解剖了10具尸体，以确定通过一种紧邻背部深层肌肉和第五腰椎横突外侧的后路入路，从骶髂关节后上方检查SIJD复位情况的可能性。结果表明，骶髂关节面后上方和骶骨翼可直接触诊或可视化。该入路有助于改善对SIJD复位的观察及髂骶螺钉置入的引导。
