Complications of Arthrography.

Serious reactions to intra-articular contrast media are exceedingly rare, and arthrography is considered to be a very safe procedure. To assess the safety of arthrography, a questionnaire was sent to 180 radiologists experienced in arthrography. The 134 respondents had performed approximately 262,000 arthrograms throughout their career. Their experience included 45 cases of infection, eight cases of anaphylaxis, and five cases of vascular complications; no deaths were reported. Most of the reactions reported were minor and included pain, vasovagal reactions, and urticaria. In addition, the respondents reported approximately 13,300 magnetic resonance (MR) arthrograms, which had been performed with intra-articular gadolinium. Of these, there were only six cases of reported reactions, all of which were minor, including vasovagal reactions, pain, and headaches.

Anesthetic and Corticosteroid Joint Injections: A Primer.

Complex joint anatomy may render the clinical diagnosis of a patient with joint pain difficult. Pain may be referred to a joint from an adjacent area (e.g., from the back to the hip) making the diagnosis difficult. The radiologist with the use of fluoroscopy is the ideal person to perform diagnostic and therapeutic joint injections. Long-acting anesthetic alone or combined with a corticosteroid may help the clinician localize the cause of the joint pain and subsequently institute the proper therapy. This article includes a discussion of the commonly used injectable corticosteroids that are available. The choice of corticosteroid is based on personal preference. Depomedrol (Upjohn, Kalamazoo, MI) is the least expensive corticosteroid available; however, a relatively insoluble drug such as Aristospan (Lederle, Deerfield, IL) or a combination drug such as Celestone Soluspan (Schering, Kenilworth, NJ) may be a better choice in rheumatoid arthritis. The technique used to inject the hip and the shoulder is discussed.

Subtalar Joint Arthrography.

The purpose of this study was to determine the accuracy and the specificity of an optimum technique of posterior talocalcaneal/posterior subtalar (PST) joint arthrography and anesthetic injection in patients with hindfoot pain. Fifty-five PST joints were studied in 55 patients. The posteromedial approach was used in the first 24 patients, followed by an anterolateral approach in 31 patients. The ease of performance, success of confirming PST needle position, and adverse effects were noted. After contrast injection, a combination of 1% lidocaine and 0.5% bupivacaine was injected. Results consisted of 47 arthrographically confirmed PST injections. The posteromedial approach was deemed more difficult; three patients had tendon sheath opacification and four had unwanted anesthesia of the toes. The anterolateral approach was technically easier and no extra-articular structures were visualized or anesthetized. Therefore, PST arthrography with anesthetic injection is optimized with an anterolateral approach.
