Arthrography-assisted intra-articular injection of steroids in treatment of adhesive capsulitis.

Following shoulder arthrography to establish the diagnosis of adhesive capsulitis, we injected steroids via the in situ arthrogram needle. Subsequent intraarticular steroids, if needed, were given at the outpatient clinic using landmarks established at the time of arthrography. Out of 18 patients treated, function sufficient to permit resumption of usual work and self-care activities returned to 16. In 11 patients, recovery was associated with painless total shoulder movement gather than a return to glenohumeral motion. This therapy appears perferable to other forms of intraarticular injection and is an alternative to surgery when physical therapy has failed.

Arthrography of the wrist joint. An experimental study.

Arthrography using 60 per cent Urografin was done on twenty fresh cadaver wrist joints. The wrists were then dissected and the arthrographic picture was correlated with the anatomical findings. The study showed that the contrast solution exactly delineated the radiocarpal joint cavity. It passed through all apertures into the adjacent joints. the arthrographic picture accurately corresponded to the anatomical observations. The pattern of a normal arthrogram was thus established. The preliminary results of a parallel clinical study in forty-nine patients are briefly described. I concluded that contrast arthrography can be helpful in the diagnosis of several conditions that show no findings on plain radiographs.

Synovial fluid eosinophilia following arthrography.

A patient recovering from an acute gouty attack developed inflammation and eosinophilia of the synovial fluid following arthrography of the gouty joint. There was no evidence of systemic allergy to the contrast agent used. It is postulated that non-immune mechanisms were involved in the accumulation of eosinophils. An additional one of six synovial fluids obtained after arthrography contained 24% eosinophils. A review of the literature emphasizes the infrequency with which eosinophils are observed in synovial fluid.

[Usefulness of arthrography of the knee in assessing the unfavorable outcome from a meniscectomy intervention].

Knee arthrography was performed in 22 patients suffering from persistent articular symptoms after meniscectomy. In 3 cases a surgically proved tear of the opposite meniscus was assessed. In 4 cases no meniscal tear was found, but 3 out of these patients had a significant anatomic lesion. In 15 cases meniscectomy was found to be incomplete, and a residual posterior horn of the medial meniscus was observed, normal in shape in 7 cases, torn or detached in 8. It is suggested that the persistence of the posterior horn of the medial meniscus after meniscectomy may cause the persistent symptoms; the value of knee arthrography before surgery is emphasized.

Role of telethermography and arthrography in rheumatoid wrist.

After briefly reviewing some of the problems relating to an early identification of synovial pathology, the authors have pointed out the actual role of telethermography and arthrography, resulting from their diagnostic experience. The two techniques were applied to a group of 40 patients affected with rheumatoid arthritis and were found to be particularly helpful: (i) either providing quite early information (telethermography); or (ii) allowing an exact topographic definition of synovial and tendinous sheath involvement (opaque arthrography), or eventually (iii) supplying a manageable means to follow their development with.

[Double contrast knee arthrography in meniscal lesions (author's transl)].

Double contrast arthrography, under fluoroscopic control, is a technically simple procedure with a high degree of diagnostic accuracy. The Authors performed 95 arthrographies in patients with suspect meniscal lesion, making a correct diagnosis of 84 (94%) out of 89 cases undergone surgical intervention. They conclude giving the indications to arthrographic examination, which needs to be limited to those cases in which the clinical diagnosis is difficult on uncertain.

Meniscal abnormalities in knee arthrography.

When carefully performed, arthrography is a safe, simple, and accurate method for the evaluation of meniscal abnormalities. Accuracy depends on an understanding of the various tear types, their arthrographic appearances, and their expected locations. The arthrographer must also be aware of other abnormalities, such as meniscal cysts and discoid menisci, which may be accompanied by meniscal tears. With careful attention to detail in positioning, filming, and interpretation, a diagnostic accuracy of 90 per cent or better can be expected in the evaluation of meniscal abnormalities by double-contrast knee arthrography.

Interpretation of double contrast arthrography in lesions of the menisci of the knee joint.

This paper deals with certain difficulties in the interpretation of arthrography of the knee performed because of suspected lesions of the menisci. On the basis of experience acquired in 197 double contrast arthrographies using fluoroscopic techniques, combined with a study of sections made in six cadaver knees, some interesting correlations between the anatomical and arthrographic appearances are illustrated. By taking these into consideration it is possible to improve still further the already good diagnostic accuracy of this method of investigation.

Wrist arthrography.

Wrist arthrography is an adjunctive procedure that may be valuable to the clinician. Although it is sensitive to particular abnormalities, it lacks the specificity to completely diagnose a given condition. Information gained by arthrography can be used a supportive evidence, in conjunction with clinical and laboratory findings, to aid in the management of individual patients.

Elbow arthrography.

Arthrography of the elbow is performed infrequently, but may be quite useful in demonstrating the presence, number, and location of intra-articular loose bodies, and in evaluating articular cartilaginous surfaces. Such information may be valuable in the selection of an operative versus a nonoperative course of treatment, and, if surgery is elected, it may be useful to the surgeon in planning the operative approach and in locating the position of all of the abnormalities present. Elbow arthrography is also of occasional value in demonstrating synovial disease, evaluating certain traumatic disorders, and verifying needle position during aspiration. A useful and accurate elbow arthrogram requires careful planning and may require considerable time to perform completely. Plain radiographs should be carefully examined. Fluoroscopic observation before injection may be extremely helpful, and thoughtful selection of the type and amount of contrast medium is necessary. Adequate arthrographic films may be obtained only after careful consideration of the abnormalities to be demonstrated and their location in the joint. Tomography is almost always necessary for a thorough evaluation.

Radionuclide arthrography and transmission imaging for assessment of painful hip prostheses.

UNLABELLED: Interpretation of the radionuclide hip arthrogram may present difficulty because of a lack of anatomical reference information. Additional transmission images to determine tracer localization may facilitate scan interpretation. METHODS: Isotope arthrography (20 MBq 99mTc-tin colloid and 57Co transmission imaging) was prospectively performed on 21 patients with painful hip prostheses and suspected stem loosening. RESULTS: The radionuclide arthrogram was positive in 10 patients and negative in 9 patients. Extravasation of tracer, confirmed by transmission images, resulted in two nondiagnostic studies. Surgery was undertaken in 10 patients and loosening was confirmed in 6 patients. In this surgical subgroup, the scan was true-positive in six patients, true-negative in two patients, false-positive in one patient and nondiagnostic in one patient. CONCLUSIONS: The combination of radionuclide arthrography and transmission imaging facilitates scan interpretation and is a recommended method for investigating suspected loosening of the femoral stem.

Magnetic resonance arthrography of the shoulder. A new technique of shoulder imaging.

Although magnetic resonance imaging is very sensitive and even though pathology in the rotator cuff is readily detected, it is often difficult to distinguish between complete rotator cuff tears, partial rotator cuff tears, and area of tendinitis. This article reports the results of a new technique for evaluation of shoulder pathology, which the authors have labeled magnetic resonance arthrography, and compares the results of magnetic resonance arthrography with those of conventional magnetic resonance imaging.

MR arthrography of the shoulder.

Although conventional MR imaging allows direct visualization of major anatomic structures, smaller intraarticular structures, including the glenoid labrum, glenohumeral ligaments, and articular surface of the rotator cuff tendon can be difficult to evaluate in the absence of a joint effusion. The authors review the techniques employed in performing MR arthrography, imaging characteristics of MR arthrography, and diagnostic utilization of the technique. Suggested indications are provided.

Ankle arthrography and chronic lateral ankle instability.

Sixty-five ankle arthrograms of the patients who underwent surgical reconstruction for their chronic ankle instability from 1987 to 1995 were studied retrospectively by comparing their operative findings. There were 15 cases (23.1%) with definite positive arthrographic findings. In the remaining 50 cases (76.9%), the arthrograms showed a "tear-drop" extravasation of dye beneath the fibular tip which we called "suspectable positive". Of these all but one, which had normal ligament, proved to correspond to the operative finding. As there was only one false positive finding among our surgical cases with both the "definite" and "suspectable" positive arthrograms, we concluded that ankle arthrography is relatively reliable and may be worth doing even in chronic cases if only for reference. Even when other diagnostic methods are negative, arthrography might help surgeons make surgical decisions in clinical symptomatic cases.

MR arthrography of the ankle

Injuries to the lateral ankle ligaments are extremely common. Many patients with acute injuries to the lateral ligament complex develop chronic ankle instability that requires surgical intervention. MR arthrography of the ankle plays a valuable role in identifying those patients who are most at risk for the development of chronic instability. MR arthrography of the ankle also aids in preoperative planning and in differentiating among other entities that can present as ankle instability.

Utilization of "used" vials: cost-effective technique for MR arthrography.

Because full vials of commercially available MR arthrographic contrast are expensive, we hypothesized that the small residual contrast in a "used" vial would be adequate for MR arthrography. After sterility testing and quantity analysis of the residual contrast in 28 vials, this method was successfully used in 10 patients. J. Magn. Reson. Imaging 2000;12:953-955.

Use of intra-articular carbon dioxide and air for MR arthrography: a feasibility study.

During animal experiments, carbon dioxide (CO(2)) and air were used as a novel contrast agent for direct magnetic resonance arthrography (MRAr). MRAr was performed after injection of CO(2) and air in the knee joints of two pigs. MR images of phantoms containing air, CO(2) and nitrogen were compared. After intra-articular injection, both present as a signal void on various sequences and permit sharp delineation of cartilage and other adjacent structures. Despite the potential for artefact generation, only a slight susceptibility artefact was seen after injection of CO(2) and air. In phantom experiments, air, CO(2) and nitrogen demonstrated identical slight regular susceptibility artefacts at the phantom margins. CO(2) MRAr can yield high contrast between cartilage, ligaments and synovium relative to the joint compartment. Therefore, this technique might be useful as an investigational method for the evaluation of cartilage surface lesions and possibly as an alternative contrast agent for clinical use.
