Radiocarpal arthroscopy and arthrography in the diagnosis of ulnar wrist pain.

The purpose of this prospective study was to compare arthroscopy with arthrography in the diagnosis of ulnar wrist pain. Thirty-seven consecutive patients with ulnar wrist pain but normal routine and stress radiographs had dynamic and static radiocarpal arthrograms (R.G.H.) and arthroscopy (J.H.R.) performed. Sixteen arthrograms demonstrated a leak of contrast into the distal radioulnar joint. Arthroscopy demonstrated a perforation of the triangular fibrocartilage complex in all 16. Seven arthrograms demonstrated a leak of contrast into the midcarpal joint. Arthroscopy demonstrated lunotriquetral instability in two and no abnormality in five. Seventeen arthrograms showed no abnormality. Arthroscopy confirmed no abnormality in nine but also demonstrated seven triangular fibrocartilage perforations and one case of isolated lunate chondromalacia. Arthroscopy findings were confirmed in eight patients who underwent a subsequent arthrotomy. Radiocarpal arthroscopy is superior to arthrography in the diagnosis of chronic ulnar wrist pain.

MR arthrography of the rotator cuff and labral-ligamentous complex.

In MR imaging of the shoulder, diagnostic success requires the delineation of complex anatomic structures and the demonstration of subtle abnormalities. Magnetic resonance (MR) arthrography extends the capabilities of conventional MR imaging because contrast solution separates intra-articular structures and outlines abnormalities. There are several major contributions of MR arthrography. In assessment of the rotator cuff, arthrographic MR images enable the accurate differentiation of full-thickness tears from other cuff abnormalities, as well as the determination of tendon quality. In shoulders with suspected glenohumeral instability, arthrographic MR images show the locations of labral tears relative to the origins of glenohumeral ligaments. This article illustrates normal arthrographic MR features of the shoulder as well as common pathological disorders of the rotator cuff and labral-ligamentous complex.

[Arthrography in humeroscapular peri-arthritis].

Degenerative changes in the shoulder joint affect the capsule much more frequently than might be expected and are not seen on a plain radiograph. Arthrography of the shoulder has become of increasing significance in view of modern surgical management. Arthrography is used particularly to demonstrate a tear of the rotator cuff (especially the supra spinatus and infra spinatus). It also shows other important abnormalities which cause pain on movement, such as adhesions, tight capsule and the formation of septa. The indications, technique and necessary records, as well as typical pathological findings, are demonstrated in forty shoulder arthrograms. Hemuro-scapular peri-arthritis is a collective term for complex, primarily degenerative or posttraumatic, changes including peri-articular calcification. Demonstration of calcification alone does not justify the radiological diagnosis of humeroscapular peri-arthritis.

[Arthrography and ultrasound scanning for the detection of Baker cysts (author's transl)].

23 knee joints with clinical evidence of Baker's cysts have been studied in comparison by arthrography and ultrasound-scanning. In 20 knees, there was correlation between arthrographic and sonographic findings. In 3 cases, a positive sonogram was not confirmed by arthrography. Possible causes for faulty interpretation and differential diagnoses have been discussed. We prefer ultrasound scanning for the diagnosis in inflammatory and degenerative joint diseases because it is entirely harmless. In cases of traumatic Baker cysts the arthrogram may reveal an additional meniscal injury.

[Reliability of double-contrast arthrography in detection of cartilage lesions of the knee joint (author's transl)].

The present work evaluates the method of double-contrast arthrography. To this end, cartilage damage on femoral condyles and tibial joint surfaces was studied in 1566 retrospectively evaluated double-contrast arthrographies. Operation reports and histological results served as control. The results of our own experiments demonstrate that even isolated cartilage lesions as small as 1 mm in diameter can be visualized.

MR imaging and MR arthrography for diagnosis of recurrent tears in the postoperative meniscus.

The accuracy, pitfalls, and limitations of magnetic resonance (MR) imaging for diagnosing a tear in the nonoperated knee are well known. However, the diagnosis of a recurrent tear can be more difficult in the postoperative meniscus. Resection or meniscal repair results in postoperative changes that can mimic a recurrent tear. To serve as a foundation, the techniques of treatment for meniscal tears are reviewed. This is followed by a detailed review of the literature on the accuracy of diagnosis of a recurrent meniscal tear using MR imaging and MR arthrography. Finally, recommendations are given as to the circumstances in which MR imaging or MR arthrography should be used for evaluation of the postoperative meniscus.

[Correlation between arthrography and intraoperative findings in knee meniscus lesion (author's transl)].

The diagnosis of knee meniscus lesion as a result of clinical findings has a relatively high rate of failure. The arthrography of the knee joint is a low risk method of examination which is not burdening the patient. Arthrography compared with intraoperative findings shows a correlation of 97,0% in 132 operations performed. This testifies evidently the high diagnostic value of this radiological examination. It facilitates that decision to perform an arthrotomy in cases, clinical findings are not clear enough.

[The clinical importance of arthrography after lesions of the meniscus and capsular ligament (author's transl)].

Clinical, arthrographic and operative findings of 100 patients were compared and analyzed by a study group with the result, that in questionable lesions of the meniscus, the indication for a double contrast arthrography was markedly reduced when plain films of the knee, an exact case history and a physical examination of the knee joint were performed. Above all, the improved examination technique, with the knowledge of the functional anatomy of the capsular ligament apparatus and the correlation of all stabilizing forces of the knee joint had reduced clinical errors in diagnosis. Clinically clearly analyzed meniscus lesions are therefore no indication for arthrography. In our clinic the indicatin will be reduced to those cases where there are still complaints after meniscectomy. There is a great advantage, if the examinating physician, the radiologist and the orthopedic surgeon cooperate closely together.

[Arthrography of the ankle joint].

Arthrography of the ankle joint was first carried out by Johnson and Palmer at the Military Hospital in Stockholm in 1940. Arthrography can be used for judging the integrity of the articular cartilage, of osteochondritis dissecans, arthritis or adhesive capsulitis. The literature shows, however, that more than 95% of the patients on whom this examination has been performed had suffered from acute trauma.

[Arthrography of the functionally disordered temporomandibular joint].

Arthrography provides accurate information concerning abnormal changes and function of the soft tissue components of the T.M.J. It is superior to all other clinical and radiological methods of examination for elucidating functional abnormalities. The increasing incidence of functional T.M.J. abnormalities and improvements in treatment make arthrography of the T.M.J. of increasing importance. The importance of views in the sagittal plane and of video recordings is stressed.

[Contrast arthrography in the diagnosis of soft tissue injuries round the elbow joint (author's transl)].

Based on the experience of 115 examinations, the authors first describes the normal radiological appearances on arthrography of the elbow joint. Subsequently, the radiological criteria are discussed which permit a diagnosis of intra- and para-articular soft tissue lesions due to closed trauma of the elbow joint. Arthrography with positive (water-soluble) contrast media enables one to diagnose rupture of the joint capsule and ligaments, and to diagnose with certainty subluxations of the various parts of the joint. Is is also possible to demonstrate haematomas between the muscles, which may lead to a reduction in joint function. Negative contrast medium (carbon dioxide, oxygen) permits the diagnosis of rupture of the insertion of the biceps.

CT and MR Arthrography of the Glenoid Labroligamentous Complex.

Because they distend the shoulder joint and bathe the labrum with contrast, CT arthrography (CTa) and MR arthrography (MRA) are both excellent tests for evaluating the labrum. In this article, we discuss the advantages and disadvantages of each examination. We also describe techniques for performing CTa and MRA, including how to maximize image quality. The normal anatomy of the labrum and glenohumeral ligaments is described and demonstrated on both CTa and MRA images. To improve communication with orthopedic surgeons, the discussion of the pathology and normal variants of the labroligamentous complex is organized by functional anatomic regions. CTa and MRA images are then used to demonstrate a variety of pathologic and normal variant appearances of the labroligamentous complex.

MR Arthrography of the Elbow and Wrist.

This article describes the present status and future directions of magnetic resonance arthrography (MRA) of the elbow and the wrist. The indications are evolving and not yet clearly defined. MRA of the elbow is useful for evaluation of collateral ligaments, the articular surfaces, and suspected loose bodies. MRA of the wrist currently is typically reserved for difficult cases. A description and a comparison of direct and indirect MRA techniques is provided. Direct MRA produces reliable joint enhancement with capsular distension. Indirect MRA does not require a radiologist experienced with arthrography but if it is improperly performed, results in suboptimal delineation of intra-articular structures. A review of pertinent normal anatomy and common variants is included as well as a discussion of pathology that is suitably demonstrated by MRA technique. Typical examples of normal variants, abnormalities, and pitfalls are illustrated to reduce interpretive error for radiologists using MRA of the elbow and the wrist.

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.

Loose hip prosthesis. Appearance in radionuclide arthrography.

Radionuclide arthrography has been found to be valuable in the diagnosis of a loose hip prosthesis. The appearance of one normal case with no loosening and two abnormal cases with loosening of femoral and acetabular components are described. To diagnose this difficult problem, radionuclide arthrography should be used more frequently.

Arthrography of the knee.

Arthrography of the knee is becoming an integral part of the evaluation of the patient with a suspected internal derangement of the knee. The examination is relatively simple, and can be performed on out-patients with conventional radiographic equipment or a modified fluoroscope. Knee arthrography has been proven safe in a large series of patients. The technique is reliable, particularly in the diagnosis of meniscus lesions. The knee arthrogram is helpful to the orthopedic surgeon to confirm suspected abnormalities, to reveal unsuspected or multiple lesions, to exclude some conditions which could be confusing clinically, or to plan a surgical approach to the knee.

Double contrast knee arthrography in the evaluation of osteochondritis dissecans.

Double contrast knee arthrography is an invaluable adjunct in the evaluation of patients with osteochondritis dissecans. The cartilage overlying the osteochondritic defect can be evaluated and unsuspected meniscal pathology accurately diagnosed. In our series, there were three unsuspected medial meniscal tears, diagnosed by arthrography and confirmed at surgery. The location of the osteochondritic defect was atypical in all four of our female patients.

MR contrast arthrography (MRA) in osteochondrosis dissecans.

Osteochondrosis dissecans (OCD) is a lesion that characteristically affects the articular cartilage and subchondral bone with the potential of fragmentation and separation. Exact assessment of cartilaginous and subchondral bony changes is mandatory for the planning of adequate treatment. Therefore, we examined 25 knees using spin echo (SE) and gradient echo (GE) sequences on a 1.5 T superconducting unit prior to and following intraarticular administration of 40 ml of a 2 mmol/L Gd-DTPA solution (MR arthrography). For evaluation (staging) a modified Clanton and DeLee scheme was employed. Verification by arthroscopy or arthrotomy was available in 24 cases. A correct diagnosis of OCD with regard to its type prior to intraarticular injection of Gd-DTPA was possible in 39.3% using T1-weighted SE sequences and in 57.4% on GE sequences. After intraarticular administration of Gd-DTPA, the rate of correct diagnoses improved to 92.9% on T1-weighted SE sequences and 100% on GE sequences. Magnetic resonance arthrography appears to be helpful for the exact assessment of the articular cartilage overlying OCD lesions as well as for the differentiation between partial and complete separation of cartilaginous or osteocartilaginous fragmentations.
