[Quality control of radiographic imaging of the lumbar spine].

The qualitative control of the roentgenographic findings was performed independently by the assessment of five x-ray specialists on 40 two-directional lumbosacral roentgenograms. The findings were based on questioners including all details and a table of the internationally used "Radiological Diagnosis". In earlier publications the anatomical and structural changes were considered the risk factors of the waist. (Osteoporosis, changes in the position of the vertebral body, change in the shape of the spine, restriction of the intervertebral cleft and deformation of the small articulations). The views of the research workers were compared by means of statistical analysis. Compared with other authors the methods of these findings are in agreement with the international norms. These findings drew attention to the necessity of an objective assessment of the subjective findings.

[Osteoblastoma in the iliac crest].

An 18 year old male patient is reported with a five year history of mild pain in his right hip. Radiological investigation showed a typical feature for osteoblastoma of iliac bone, with two niduses. En bloc excision was performed. The histological examination's result was also osteoblastoma.

[Ultrasonic examination of the shoulder joint].

The anatomical basis of the application of ultrasonography to the examination of the shoulder joint and the diagnostic information gained by the technical possibilities of it are discussed. The author claims that by means of ultrasonic examination it is possible to judge the fact and localization of the rotatory cuff, the lesions of the tendon of the long head of the biceps muscle and inflammation of the joint, as well as certain lesions of the soft parts. In addition, it is possible to form by means of ultrasonography an objective judgement of the result of reconstructive joint operations. The values of the information gained by ultrasonic examination is compared to that of arthrography, computertomography and magnetic resonance examination. The author is of the opinion that of all these methods ultrasonic examination should be applied first.

[Cardiac and cardiopulmonary changes in systemic lupus erythematosus].

(SLE) One hundred patients suffering from systemic lupus erythematosus (SLE) were examined by clinical, non invasive cardiological, radiological and laboratory methods. Valve diseases were revealed by M-mode echocardiographic examination in 17 patients. 14 patients had various conduction disturbances. Out of the remaining 83 patients not having any valve disease, systolic dysfunction of the myocardium was detectable in 17 persons and pericardial effusion in 3 persons. Spirometric alterations have been found in 64 persons and cor pulmonale has been diagnosed in 8 persons.

[A retrospective analysis of x-ray changes of the hip joint].

In 74 patients who had an endoprothesis implanted for a radiologically defined coxarthrosis preoperative radiographs were compared with contact radiographs of the resected femur head. In case of a reduction of the radiological width of the articular cavity an evaluation of the underlying cartilage damage at the femur head and the acetabulum is possible in one half of the cases. We were able to confirm cysts on the post-resection radiographs in 85.1% of the cases. Small bone fragments interpreted as necrosis, bone sclerosis and small indents of the femur head were confirmed in 70% of the cases. In the resected joint 7.8% more erosions were found than in-vivo. Sclerotic atrophy was seen twice as often in the resected joint than in-vivo. A comparison of the trabecules of the spongiosa for the evaluation of bone structure is possible only in part with the method described here.
