TAILIEUCHUNG - Ebook Atlas of ultrasound-guided musculoskeletal injections: Part 2

(BQ) Part 2 book "Atlas of ultrasound-guided musculoskeletal injections" presents the following contents: Sacroiliac joint injection, hip joint injection, hip joint injection, intraarticular injections of the knee, proximal tibiofibular joint injection, distal quadriceps injection and tenotomy, distal tibiofibular joint injection,. | SECTION V Pelvis CHAPTER 45 Sacroiliac Joint Injection Mark-Friedrich Berthold Hurdle MD KEY POINTS Use a 25-23-gauge needle. The sacroiliac joint is usually most accessible at the A high-frequency curvilinear array transducer is required caudal pole. for most patients. The probe is placed in an axial plane over the joint. Pertinent Anatomy The sacroiliac joint is a diarthrodial joint consisting of the articulation of the lateral sacrum with posterior medial ilium Figure 45-1A B . The joint is stabilized by posterior sacroiliac ligament sacrospinous ligament sacrotuberous ligament Figure 45-1C . The cephalad portion of the posterior joint contains the interosseous ligament and is not a true joint capsule.

Ligamentous structures about the sacroiliac joint. 184 Chapter 45 Sacroiliac Joint Injection 185 Common Pathology A host of conditions including degenerative changes joint infections structural abnormalities inflammatory disorders pregnancy joint dysfunction and metabolic conditions have been implicated in sacroiliac joint pain. Sacroiliac joint SIJ pain referral patterns may overlap other painful conditions involving the low back and lower extremities. Typically sacroiliac pain involves the posterior superior iliac crest region of the affected side radiating distally. Although a host of provocative maneuvers are helpful in establishing the diagnosis an intraarticular injection can help with confirmation. Ultrasound Imaging Findings The SIJ is best visualized using a curvilinear probe initially placed directly over the posterior superior iliac crest on the side of interest Figure 45-2 . The S1 foramen can be visualized medial to the cleft of the upper portion of the SIJ. The probe is then kept in the axial plane and slid distally until the lower pole is seen close to the posterior sacral foramen of S2. FIGURE .
