[Polysegmental andersson lesion in ankylosing spondylitis (roentgenological-histological synopsis) (author's transl)].

Basing on roentgenological observation of the course of the disease, and on postmortem examination, of a patient with polysegmental Andersson lesions (known as spondylodiscitis) in ankylosing spondylitis, the article reports on the histological and often also clinico-roentgenological possibility of differentiating between an inflammatory and non-inflammatory type of this destructive lesion. The non-inflammatory type of Andersson lesion reflects a fracture due to fatigue, or its sequel, eg pseudarthrosis, in the stiffened axial skeleton. In this particular patient, renal osteopathy had favoured the genesis of the disease.

[Computer tomography of the sacroiliac joints (author's transl)].

Computer tomography, like conventional radiography, can demonstrate inflammatory, degenerative or reparative, traumatic and neoplastic lesions of the sacroiliac joints. In some cases computer tomography adds important information, for instance as regards soft tissue changes near the S.I. joints in the presence of neoplastic or posttraumatic lesions (tumour extension, hematoma). Computer tomography is also able to demonstrate minor disalignment of the sacro-iliac joints (so-called sacro-listhesis).

[Marginal osteophytes as a radiological and clinical indicator of patellofemoral arthrosis (author's transl)].

Radiological and pathological comparisons carried out on patellae at autopsy have shown a statistical relationship between the size of marginal patellar osteophytes and radiologically invisible ulceration of the joint cartilage. Patellar osteophytes greater than 2 mm. show a 100% association with cartilage ulcers. The detritus originating from the ulcerated cartilage is a potent irritant of the synovial membrane. The radiological demonstration of marginal patellar osteophytes therefore provides evidence concerning the severity of the arthrosis; the larger the patellar marginal osteophytes, the greater is the need for treatment of the painful arthrosis. The lateral and upper margins of the patella are the sites of predelection for the osteophytes. The medial patellar facet is the site of predelection for the cartilagenous ulcers.

[The value of a systemic method for radiologic examination of the stomach (author's transl)].

A method for systematical examination of stomach is described. The exporation is done with different technics (double-contrast, full-filling, compression). Films are taken in 13 positions. The purpose of the method is, to get an exact documentation of all parts of the stomach and to raise the number of detected lesions. Further, the training of young radiologists will be easy and more effectiv.

[Histomorphology of the sacroiliac joint in ankylosing spondylitis and relevance to treatment (author's transl)].

The sacro-iliac joint of a patient who had been ill with ankylosing spondylitis for half a year was investigated histologically at necropsy. Two basic histological phenomena were apparent: inflammation and aggressive proliferating chondroid metaplasia at the chondro-osseous junction and in the subchondrium. Joint cartilage degeneration, joint cartilage fusion, capsule ossification and subchondral bone apposition were observed as epiphenomena at the sacro-iliac joint. Both basic morphological phenomena are due to the same cause which has not yet been clarified. They progress independently of each other with varying intensity. This assumption explains differing opinions and the relation of inflammation and pathological ossification of the skeletal axis as well as the unsatisfactory objective results of treatment. Only a combination therapy directed against both morphological basic phenomena will result in an objective therapeutic success and not only in a symptomatic improvement of ankylosing spondylitis.

[The radiogical criteria of juvenile rheumatic cerivical synostosis in adults (author's transl)].

The radiological criteria of juvenile, rheumatic, cervical synostosis discovered in adult life are described and illustrated. These include: involvement of few or many segments, a tendency to bony ankylosis of the diseased intervertebral joints, dysplasias or hypoplasia of the vertebral body and intervertebral disc and dysplasias of the neural arches and hypoplasia of the transverse processes. Pathological ossification may involve the ligamentum flavum, the annulus, or the entire disc. The differential diagnosis of juvenile, rheumatic, cervical synostosis includes congenital block vertebrae, Klippel-Feil syndrome, acquired block vertebrae, juvenile ankylosing spondylitis, synostosing, intervertebral osteochondrosis and myositis ossificans progressiva.

[Hyperostosis triangularis ilii -- a sacro-iliac stress phenomenon Part. 2 (Incidence, prognosis, pathogenesis, aetiology, tracer studies, differential diagnosis) (author's transl)].

The anterior iliac margin adjacent to the sacro-iliac joint contains a physiological zone of hyperostosis. Its shape is that of a triangular pyramid. Because of its small size, it is radiological invisible, but is nevertheless an indication of the presence of normal stresses passing from the mass of the trunk to the lower extremities. If for any reason, such as is described in this paper, the stresses on the hyperostosis zone are increased, the latter becomes enlarged, while still keeping its shape. It then appears on the radiograph as hyperostosis triangularis ilii. In approximately 50% of cases there is a simultaneous but variable sacral hyperostosis. Observations on 40 patients, together with two autopsies and radionucleide investigations suggest that hyperostosis triangularis ilii represents a potentially reversible bone reaction of the physiological hyperostosis of the anterior iliac margin. The clinical differential diagnosis raised by the radiological finding of a "triangular ilium hyperostosis" is discussed.
