Any joint can be aspirated; however, some joint aspirations require the use of ultrasonographic or fluoroscopic guidance. [9] Ultrasonography allows the clinician to confirm the presence of fluid before aspirating. It can also be helpful in aspirating deep or technically difficult joints. The hip joint should be aspirated under ultrasonographic guidance. Joints of the spine, including the sacroiliac joint, should be aspirated under fluoroscopic guidance. Guidance for aspiration is also recommended when blind attempts have failed to access any joint fluid.
