[Arthrography of the wrist: procedures and normal results (author's transl)].

The results of 31 opaque arthrographies of the wrist carried out under two different circumstances are reported. --In a first group the investigation was made immediately after or within a longer period following injury to the wrist or forearm. The results supply information to the surgeon on the condition of the triangular ligament in dislocation and partial dislocations of the inferior radioulnar joint, caused by an architectural fault in the radius after trauma (fracture of the head, diaphysis, or lower extremity). Simple reduction of the radius, without intervention on the inferior radio-ulnar joint, provides an excellent functional result when the triangular ligament is simply stretched. When it is torn (sprains, dislocation locally or at a distance) results are not very convincing in spite of the many possible procedures available. Arthrography easily reveals the presence of a reflex dystrophy complicating the injury. Both the radiological and clinical signs give characteristic pictures of the condition. --This examination is still only used infrequently for the diagnosis of chronic inflammatory rheumatic diseases. The arthrographic images appear very early, however, and are characteristic of an inflammatory synovial lesion. Examinations were carried out mainly for evaluation before therapy, surgical in the case of a synovectomy, medical for a chemical or isotopic synovial treatment. Arthrography in a acutely inflammed joint is followed by an injection of corticoid, sometimes associated with a local antibiotic. This rapidly relieves the patient and prevents worsening of the acute inflammatory process. Arthrography of the wrist is a simple, painless, rapidly performed examination. There has never been a failure, any incident, or accident. It appears to be the only direct exploratory procedure for this joint. A precise anatomical evaluation can be made from the image which gives a true picture of the different anatomical structures.

[Pseudotumoral rheumatoid coxitis (author's transl)].

Two cases of rheumatoid coxitis of the macrogeodic type are reported. In one case, there was a very large anfractuous cavity in the socket and head, complicated by a pathological fracture of the socket, which raised the suspicion of a malignant tumor. The authors review the characteristics of these macrogeodic forms of rheumatoid arthritis, about forty cases having been reported in the published literature.

[Partial algodystrophy].

The authors describe, on the basis of 7 cases, a special form of decalcifying algodystrophy not described in the literature, characterized by a very localized pain beginning gradually, or more often suddenly. It is of mechanical or mixed type, accompanied by local, pseudo-inflammatory signs being either apparent or discrete, very elective and very sharp pain upon palpation of a very limited area of a condyle or a tibial plate, with hyperfixation located through scintigraphy with technetium 99m polyphosphates, and regressing either spontaneously, or more quickly under treatment, of which thyrocalcitone is the essential part, without undergoing a phase of intense loco-regional demineralization. This form of algodystrophy, that they propose to call partial algodystrophy, can, like the other forms of algodystrophy, appear in monofocal or plurifocal form, either straight off or at a distance from the first incidence, which leads this new radioclinical type to be considered a simple form of algodystrophy of the limbs, midway between the types without radiological anomaly during development and the complete and extensive ones with major radiological signs. Finally, they underline the great value or scintigraphy in diagnosing this form of algodystrophy and algodystrophy without radiologic anomaly.

[Arthropneumotomography in recurrent dislocations and subluxations of the shoulder. Methods, results, and indications in 45 cases (author's transl)].

The authors describe the results of arthropneumotomography in 45 patients with recurrent dislocations or subluxations of the shoulder. The method used is given in detail and the need for excellent quality glenoid profile sections, as described by Bernageau, is emphasized. The results are analyzed for bone lesions, capsuloligamentary lesions, and intra-articular foreign bodies. The two latter conditions are specifically demonstrated by arthropneumotomography. These results are then described radiological and surgical correlations, and the indications defined. Arthropneumotomography is therefore of value when a decision is to be taken as to the need for operation.

[Fatigue fractures of the metatarsal bones].

The authors report 145 cases of fatigue fractures including 125 of the metartarsals. They compare this distribution that reported by others, in particular in German work. After study of the different types of clinical picture the authors emphasize the importance of repeated and high quality radiological examinations. They describe the four stages of radiological evolution. Each of the images taken out of its context is misleading. They may lead to the diagnosis being missed and thus should be well known.

[A duodenal schwannosarcoma with hepatic metastases (author's transl)].

The authors present a case of duodenal schwannosarcoma, a rare tumor revealed by an ordinary dyspeptic syndrome. Radiological examination of the stomach revealed the presence of an internal paraduodenal diverticular picture. Arteriography showed the hypervascularized tumor as well as its extension and hepatic metastases.

[Simultaneous discovery of osteopetrosis in a mother and fetus on the occasion of radiopelvimetry (author's transl)].

On the occasion of radiopelvimetry, requested for suspected narrowed pelvis, osteopetrosis was discovered simultaneously in the mother and fetus. At birth, the child was perfectly normal and subsequently showed no clinical or laboratory disorder apart from diffuse osseous condensation. The genetic enquiry proved difficult owing to the family situation and up to this day it is not complete and definitively stopped. Although the beginning of the osseous disorders starts in the fetus on an average at the 4th to 5th month of pregnancy, Albers-Schonberg disease is exceptionally diagnosed during the parenatal period. In fact, the incidence of osteopetrosis in the population remains low and on the other hand prenatal radiological examinations are sparingly requested for specific clinical indications. It is the simultaneous discovery of the condition in the mother and the fetus which makes this case a novel one. The discovery of the fetal involvement does not permit prediction concerning progress towards a benign or malignant form.
