Arthrography in the diagnosis of fractures of the distal end of the humerus in infants.

Single-contrast arthrography was performed in six infants who had an injury to the elbow because the exact nature of the injury was uncertain from interpretation of the plain radiographs and clinical findings. A correct diagnosis was made in all six patients, and it significantly altered the treatment in five. Four lesions were a Salter-Harris Type-I fracture and two were a Salter-Harris Type-II fracture. Three patients had a closed reduction, two required no reduction, and one had an open reduction. Child abuse of two infants was confirmed, and it was suspected in another two.

Cervical facet joint arthrography.

We describe a technique for cervical facet joint arthrography; a posterior approach is used. The patient is positioned prone, the neck flexed maximally, and the head turned 60-90 degrees opposite to the side of injection. The x-ray tube is angled cephalad in order to obtain a true tangent to the facet joint. The needle is inserted using fluoroscopic control in a direction parallel to the x-ray beam. Before the therapeutic infiltration, the intraarticular position of the needle is confirmed by injecting 0.3 ml of contrast medium.

Lumbar apophyseal joint arthrography.

Lumbar apophyseal (facet) joint arthropathy is an important cause of low back pain and sciatica. Apophyseal joint arthrography sometimes shows "leakage" of contrast medium from the joint capsule. A histological explanation for this "leakage" at the lumbo-sacral apophyseal joint is suggested.

[Investigations on the retention period and tolerance of Hexabrix as x-ray contrast medium in arthrography (author's transl)].

Arthrography of the knee joint was performed in 12 domestic pigs using Hexabrix (meglumine and sodium ioxaglate). Conray EV (sodium and meglumine iothalamate) was used for comparison. X-ray films were taken at periodic intervals. Hexabrix was found to stay slightly longer in the joints. The animals were sacrificed at 3 different times after injection and the synovial membrane of the knee joints and the joint cartilage of the patella were assessed histologically. 3 of 6 joints showed a strictly limited focus with leukocytes in the fat pad 24 hours after the injection. In the other cases no inflammatory reactions were seen after injection of the contrast media.

[Studies on the cervical facet joints using arthrography of the cervical facet joint (author's transl)].

In order to elucidate the pathological changes of the cervical facet joint probably representing one of the causes of the neck and shoulder pain, the author developed the arthrography of the cervical facet joint and applied this method to 157 joints of 83 patients. Eight cadavers were also used to evaluate the method based on an anatomical basis. Cervical facet joints of patients with tenderness on the lateral side of the neck were studied. The technic used in this method using X-ray T.V. was described and the arthrograms obtained on the dissected specimens were compared with the anatomical findings. The arthrogram of the middle and lower cervical facet joint was classified into the type with regular joint margin, the type with slightly irregular one and the type with irregular one, or the type with sharp lateral margin and the type with unsharp one. In 80% of the 142 joints in total, a communicating pathway was found from the facet joint to the interlaminar portion, interspinous portion, contralateral facet joint, para-extradural space and cervical extradural space. These arthrograms were analyzed. The visualization of the atlanto-axial joint was also achieved. Even in normal subject, a communication to the contralateral side via the surface of the axial spine was demonstrated.

[Septic arthritis in newborns and infants--the value of arthrography in diagnosis of post-inflammatory knee defects].

Double-contrast arthrography of the knee was performed on 16 knees in 14 children, who after septic arthritis of the knee in newborn and neonatal period, showed defects of the secondary ossification centers of the femur or tibia on plain radiographs. Cartilaginous epiphysis, normal in shape and volume, was present in 11 cases. In 3 cases cartilaginous epiphysis of the femur was present, but had diminished size.

[A comparison of digital radiography and conventional x-ray diagnosis for shoulder arthrography].

Fifty double-contrast arthrographies of the shoulder were obtained using conventional film-screen methods as well as by digital luminescence radiography (DLR). The supplied picture-evaluation programs had to be modified and improved prior to this study. In DLR two different post-processed images were obtained, one resembling a conventional film-screen, the other with an intensified edge-enhancement. Some of the digital luminescence radiographs were exposed with only 50% of the conventional doses. A comparison showed the equivalent diagnostic values of both the improved DLR and the conventional film screen. Even a reduction of the exposure dosage did not lead to a loss of information.

[Magnetic resonance imaging. Differentiation with other diagnostic procedures used thus far in examination of the wrist, such as arthrography and scintigraphy].

MRI can be regarded as a standard procedure for diagnosis of the painful wrist. Because of its high costs, it must be used with discretion. For the detection of lesions of the marrow, joint effusions and soft tissue pathology (exception for ruptured ligaments), MRI is generally the most sensitive imaging modality. It shows the living part of bone and soft tissue with unique contrast. An integrative imaging approach including MRI is often successful. X-ray of the wrist is the basic investigation. Ultrasound often allows the diagnosis of pathology of ganglia, tendons and vessels. Lesions of the ligaments are shown best by arthrography, although MRI can also demonstrate these lesions. The introduction of MRI has limited the use of CT to pathologic changes in cortical and cancellous bone and displacement or malalignment. Scintigraphy and MRI are mostly complementary rather than mutually exclusive.

Arthrography and computed arthrotomography study of seventy patients with primary glenohumeral osteoarthritis.

Seventy patients with primary glenohumeral osteoarthritis underwent roentgenographic and computed tomography studies. Glenohumeral joint space loss and a normal acromiohumeral space were the roentgenographic inclusion criteria. Women made up 61% of the sample. The dominant shoulder was affected in 95% of cases and both shoulders in 41%. Mean age at first evaluation was 65 years. Arthrography showed a tear confined to the supraspinatus tendon in 16 cases (23%); no patients had tears involving more than one tendon. Computed tomography demonstrated glenoid retroversion (mean 16 degrees) but was unable to differentiate primary glenoid dysplasia from wear due to osteoarthritis. Posterior subluxation of the humeral head was found in 28 cases (40%) but was not consistently correlated with the presence of glenoid retroversion.

Characterization of anatomic communications between the femoropatellar joint and lateral and medial femorotibial joints in cattle, using intra-articular latex, positive contrast arthrography, and fluoroscopy.

OBJECTIVE: To evaluate the frequency of communication between the lateral and medial femorotibial joints and the femoropatellar joint in cattle. DESIGN: 1 of 3 injection sites was randomly assigned to each ox. ANIMALS: 102 limbs were obtained from 55 fresh bovine cadavers presented for necropsy with problems unrelated to the stifle. PROCEDURE: The joints were injected with a mixture of latex and barium sulfate. Communication between 2 or more joints was determined by the presence of latex and contrast material in a joint adjacent to the injected joint by examining frozen sections and positive-contrast arthrography. RESULTS: Communication between the 3 joints was present in 58 (56.9%) limbs. The femoropatellar and the medial femorotibial joints always communicated. Thirteen of 38 (34.2%) specimens injected in the lateral femorotibial joint did not communicate with the 2 other joints. The femoropatellar joint communicated with the lateral and medial femorotibial joints on the distal abaxial aspect of the trochlear ridge. CONCLUSION: Individual anatomic variation of the stifle in cattle should be considered when diagnostic or treatment protocols are established. CLINICAL RELEVANCE: The lateral femorotibial joint should be treated separately because it does not consistently communicate with the femoropatellar or medial femorotibial joint.

Characterization of anatomic communications of the fetlock in cattle, using intra-articular latex injection and positive-contrast arthrography.

OBJECTIVE: To evaluate the frequency and sites of communication between the lateral and medial synovial sacs of the metatarsophalangeal or metacarpophalangeal joints in cattle. ANIMALS: 188 limbs were obtained from 55 fresh bovine cadavers submitted for necropsy because of problems unrelated to the fetlocks. PROCEDURE: In each ox, lateral or medial synovial sacs of each fetlock were randomly assigned. Joints were injected with a mixture of latex and barium sulfate. Communication between 2 joints was determined by presence of latex and contrast material in a joint adjacent to the injected joint by examining frozen sections and use of positive-contrast arthrography. RESULTS: Communication between the 2 synovial sacs existed in 186 of 188 (98.9%) specimens. The communication site between lateral and medial synovial sacs was located at the level of the proximal sesamoid bones, between the distal aspect of the interdigital band of the axial branch of the interosseus muscle and the metacarpal or metatarsal bone. CONCLUSIONS AND CLINICAL RELEVANCE: Although communication between the lateral and medial synovial sacs did not exist in 2 specimens, the fetlock in cattle can be treated as 1 compartment.

[The Donauspital-Stolzalpe concept (Danube Hospital, Vienna, Austria). Corrective osteotomy with selective labrum surgery following preoperative MRI arthrography].

Concomitant pathologies (labral lesions, intra-/extra-osseous ganglia and stress bone marrow edema) in adult residual hip dysplasia (RHD) might influence the outcome of conservative hip surgery. The aim of our prospective clinical study was to assess the value of preoperative MR arthrography in diagnosing concomitant lesions and in making surgical decisions in RHD. The first 37 consecutive patients with a minimum follow-up of 18 months have been analysed. All 37 patients presented RHD with the clinical symptomatology of labral lesions and underwent routine preoperative MRA. According to clinical, radiological and MR arthrographical criteria, these 37 patients were subdivided into four therapeutic subgroups: (1) reorientation of the acetabulum using the Tönnis triple pelvic osteotomy (TPO); (2) intertrochanteric varisation osteotomy (IVO); (3) palliative decompression with only symptomatic partial resection of the torn labrum (PALL); (4) primary total hip replacement (TEP). Based on the preliminary clinical and radiological outcomes of these four subgroups, the following conclusions can be drawn: labral lesions are considered to be a sign of chronic joint instability. Therefore, acetabular malorientation should be corrected by redirectional osteotomy of the acetabulum (TPO-subgroup) even in low grades of RHD if labral lesions are present. "Palliative" labral resections without corrective osteotomy (PALL subgroup) in secondary osteoarthritis due to RHD are definitively obsolete, because they rapidly progress to severe osteoarthritis due to surgically accelerated joint instability. In RHD with highly osteoarthritic hip joints and concomitant lesions, one should not hesitate to perform primary THR even in young patients.

Shoulder MR arthrography: in vitro determination of optimal gadolinium dilution as a function of field strength.

PURPOSE: To find the optimal contrast agent dilution to maximize signal intensity (SI), signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR) in shoulder MR arthrography using MR systems operating at different magnetic field strengths. MATERIALS AND METHODS: Autoptic human glenohumeral ligaments were inserted in eight egg-shaped 20-mL phantoms filled with saline and gadolinium diethylenetriaminepentaacetic acid bismethylamide (Gd-DTPA-BMA) in different dilutions of 0.5, 1, 2, 2.5, 5, 12.5, 50 mmol/liter, to simulate the shoulder articular capsule. These phantoms were inserted inside two plastic 240-mL phantoms filled with water. MRI was performed on 0.2-, 0.5-, 1.0-, 1.5-, and 3.0-T MR systems using a three-dimensional gradient echo (GRE)-T1-weighted pulse sequence. SI, SNR, and CNR were determined. RESULTS: Peak SI and SNR were found at 5 mmol/liter, with the exception of the 0.2-T scanner, where the maximum was at 2 mmol/liter. Peak CNR was observed at 1 mmol/liter for the 3-T scanner, at 2 mmol/liter for the 0.2- and 0.5-T scanners, and at 5 mmol/liter for the remaining scanners. CONCLUSION: The optimal SI and SNR are provided by 5 mmol/liter contrast agent dilution. Peak CNR was found in a range between 1 and 5 mmol/liter dilutions, depending on the strength of the magnetic field.

The lateral approach for hip arthrography.

Despite advances in imaging techniques, hip arthrography is still a useful diagnostic tool. We have found that the lateral approach to the hip joint, with the needle inserted superior to the greater trochanter and parallel to the table top under fluoroscopic control, allows easy advancement of the needle into the lateral hip joint space.

Air embolism as a complication of hip arthrography.

As an aid to correctly placing the needle tip within the hip joint during arthrography, injection of small amounts of air has been used to outline the joint space. Over a period of seven years, air embolus has been noted in three pediatric patients, twice with minor symptoms, and once with cardiac arrest. Even small amounts of air (less than 5 cc) injected accidentally intravenously may cause dangerous complications in small infants. If this technique is to be used, it is recommended that small amounts of carbon dioxide or oxygen be used instead of air.
