Sacroiliac joint injections and radiofrequency ablation for pain management: A clinical review

Figure 1 Joint structure[10]. A: The sacroiliac joint is in a position, where joint lines run parallel to the line of gravity; B: The sacral articular surface; C: The cross-sectional image of joint, shows posterior and anterior regions are syndesmoses and synovial joints; D: Syndesmosis, which is composed of sacrospinous ligaments, posterior sacroiliac ligaments, iliolumbar ligaments, and scarotuberous ligaments from posterior side; E: The ilium articular surface. Meanwhile, the redlines on both sacrum and ilium side indicate the synovial regions. Citations: Toyohara R, Ohashi T.
