[Total hip prosthesis. Current indications (author's transl)].

The various problems posed by total hip prosthesis are first described. The authors then analyse the various parameters which should guide the choice of this technique which must be used only when all other solution have failed. The recent development of prostheses without cement has made it possible to widen the application of this surgery to younger patients. Two special cases are finally reported: the role of total prostheses in the treatment of sequelae of fractures of the acetabulum, and in disarthrodesis of the hip with insertion of a total prosthesis.

Comparision of low dose heparin and low dose heparin combined with aspirin in prevention of deep vein thrombosis after total hip replacement.

In a prospective randomised trial, two groups of 20 patients each were compared. The first group received low dose heparin (t.i.d.) and the second group received low dose heparin (t.i.d.) combined with aspirin. The incidence of deep vein thrombosis (DVT) were determined using both radioactive fibrinogen uptake test and venography. The correlation between the two methods of diagnosis was better than 90%. There was no significant difference in the incidence of DVT between the two prophylactic regimen. A significant tendancy towards increased bleeding in observed with the combination of low dose heparin and aspirin.

[Arterial vascularization of the 3rd and 4th portions of the duodenum. Recent acquisitions].

New knowledge on arterial blood supply of the 3rd and 4th parts of theduodenum. Injection of the digestive arterial system in 15 adult subjects allows the study of the blood supply of the 3rd and 4th parts of the duodenum. Although the duodeno-pancreatic arches are constantly found, the authors showed that the branches to the duodenum have a variable layout. On the right of the superior mesenteric artery, the distribution of the branches is always regular on both sides of the 3rd part of the duodenum. On the other hand, on the left of this artery, there is sometimes a vascular hiatus which may extend to the duodeno-jejunal angle. Although in 60 per cent of the cases, this part of the duodenum is well supplied with blood on both surfaces, in 40 per cent of the cases on the other hand, there exists an avascular area on both sides. This lay-out is not favorable for division and anastomosis of this segment of the digestive tract.

[Vascularization of the transverse colon].

Results of 21 injections of the transverse colon with coloured latex. The superior and inferior mesenteric arteries are separately injected. Dissections allowed the study of the topography and width of the colic transverse vessels. Collateral circulation is also described. A middle colic artery is present in 85% of the cases. The length of transverse colon vascularized by each arterial system is related with accuracy to the number of arcades issued from each system. The superior mesenteric artery prevails in the blood supply of the transverse colon (70% of its length).

[New acquisitions on the arterial vascularization of the 3d and 4th portions of the duodenum. Surgical applications].

The authors studied the blood supply of the 3rd and 4th parts of the duodenum in 15 adult subjects. Although the duodeno-pancreatic arches are constantly found, the branches to the duodenum have a variable lay-out. On the right, the superior mesenteric artery, the distribution of which is always regular on both sides of the 3rd part of the duodenum. On the other hand, on the left, the superior mesenteric artery, there is sometimes a vascular hiatus which may extend to the duodeno-jejunal angle. Although in 60 p. cent of cases this part of the duodenum is well supplied with blood on both surfaces, in 40 p. cent of cases on the other hand, there exists an avascular area on both sides. This lay-out is not favourable for division and anastomsis of this segment of the digestive tract.

[Does the phrenico-gastric ligament exist?].

On thirty cadaveric dissections, we studied the so-called "phreno-gastric" ligament. In fact, it appears that there is an adhesion between the fundus and the posterior wall in only 60 % of the cases. This adhesion is always very loose, easily cleaved and in no case is there a real fibrous suspensory ligament. Moreover, in 40 % of the cases, the posterior surface of the fundus is entirely covered by peritoneum and is free in the bursa omentalis. In that case, the posterior surface of the stomach is connected with the diaphragm by a very short meso extending on the right to the meso esophagus and on the left to the gastrosplenic ligament.

[Anatomic variation of the aortic coronary openings (apropos of 80 dissections)].

A series of 80 heart dissections, compared with a survey of the literature shows that:--both coronary ostia are usually in the right anterior and in the left posterior position, in the commissural plane, at the level of the corresponding sinus of Valsalva (the left one being often superior in size to the right one).--anatomic variations of the coronary ostia (especially variations of the left coronary ostium) may be summed up into 3 patterns: Variations in number : sometimes, there is only one aortic coronary ostium, usually owing to a left coronary artery originating from the pulmonary artery; a common aortic ostium for a single coronary artery is not frequent. Multiple ostia are the most common variations : an accessory artery may arise from a separate ostium (often the "third coronary artery" from the right aortic sinus; sometimes the anterior descending and the circumflex arteries may originate from separated orifices). Variations in origin remain few, affecting most often the left ostium. Variations in size reflect the corresponding coronary plexus preponderance.

[Anatomic variations of the common trunk of the left coronary artery (apropos of 80 dissections)].

An anatomic study of the main left coronary artery is reported : important anatomic variations may occur:--sometimes, the main left coronary artery is missing (1 % of the cases),--its origin may be unusual (from the pulmonary artery),--its average length is 11 mm; but, it may be longer (35 mm) and sometimes very short (less than 8 mm in 15 per cent of the cases) : this last aspect has to be taken in account by the surgeon during aortic valve surgery if a coronary perfusion has been decided.--At last, its division into two branches (anterior descending and left circumflex) is the most usual (65 or 70 per cent of the cases). A third branch of division may exist (diagonal or lateral branch) in about 20 to 30 per cent of the cases. The left coronary artery may also divide into four (or even five) branches in 5 to 10 per cent of the cases.

[Aortic ruptures in traffic accident traumatology].

8 cases of rupture of the aorta seen in a series of 62 autopsies were studied in the context of a multidisciplinary enquiry into road accidents. In the light of these cases, the literature and experimental findings, different mechanisms are described, an essential step in the prevention of this lesion which is the main cause of death in 15 p. cent of cases.

[Circular fractures of the skull base during traffic accidents].

With reference to 5 cases of circular fracture of the base of the skull occurring in relation to road accidents, the literature is reviewed. Two different types may be distinguished: --"compression" fractures, --"hyperextension' fractures, the latter being special on the basis of the site of the fracture line and the application of forces via the face or chin. Reconstruction of trajectories during accidents, on the basis of the anatomical lesions and the damage caused to vehicles, as well as the study of films made during the experimental reproduction of similar lesions, make it possible to explain the mode of production of these hyperextension fractures. Such understanding is essential to the study of safety precautions for vehicle occupants.

[Sequelae of acetabulum fractures treated by total hip prosthesis].

The authors have treated by total prosthesis 39 cases of fractures of the acetabulum, at the stage of severe sequellae. 21 of them had been initially treated conservatively, and 18 had been previously operated on. 23 times they used conventional prosthesis anchored with cement. 8 cases became loose and had to be re-operated on. 16 times an original prosthesis made of highly porous metal was used with no complication at the present time.
