[Results of primary reconstructive arthrodesis of the calcaneus (study of a homogenous series of 55 fractures of the medical surface of the calceneus)].

55 cases of calcanear fractures (thalamus) have been treated with the Stulz procedure (early subtalar arthrodesis and calcanear reconstruction), associated with a repair of the great apophyse. All the cases are comparable and the results are considered as good or excellent in 93,8 p. 100 of them. The results are interpreted accordingly to subjective and objective tests. The result is depending of the type of the lesion, the patient's profession and the nature of the trauma. The result obtained at the time of fracture uniting will stay stable, will never deteriorate and sometimes improve. The early arthrodesis and reconstruction remains a good procedure for the comminutive fractures of the thalamus, which are considered as the most difficult to correct perfectly. For this reason, the simple reconstruction is often responsible of secondary subtalar arthrosis.

[Synthetic prostheses used in surgery to repair abdominal wall defects (excluding groin hernias). Characteristics, in situ behaviour and applications].

This study is an updating on synthetic prostheses used today to repair incisional hernias, eviscerations and abdominal wall defects due to a severe infection or a parietal excision of malignant tumours. The present prostheses are the fruits of the constantly developing plastic industry. Their characteristics and types (mesh or patch), together with the materials they are made of, are studied taking this development into account. The tissular reactions caused by prostheses are different depending on whether the material they are made of is an absorbable one or not. Published data on animal experimentation are largely used in this part of the study. A significant part is also allocated to the pathobiology of prostheses infection on which is based prevention of risk infection in the surgical practice. A synthetic prostheses has to be chosen depending on its characteristics and the tissular reactions it generates. In a septic environment, only absorbable prostheses can be used without risk. As for incisional hernias, which allows the authors to refer to their own expérience, the choice also depends on both the surgeon's own conception of the treatment and its purpose. The defect recovery after parietal excision of malignant tumours is eased by the use of a synthetic prostheses. In the future, synthetic prostheses will be even more used than today in the repair of abdominal wall. A present, the materials they are made of keep on being developed.

[Surgical treatment of calcanear fractures (103 cases). Reconstruction-arthrodesis, or reconstruction (author's transl)].

In a twelve-year period, 103 calcanear fractures (thalamus) were operated on, either by the Stulz procedure (calcanear Reconstruction-subtalar Arthrodesis [83 cases]), or by Reconstruction (20 cases). During the first seven years, the Stulz procedure had been performed systematically. During the following five years, indications were shaded between 28 reconstruction-arthrodesis and 20 reconstructions. A complete preoperative radiological study, including especially horizontal calcanear tomography enables to precise what type of injuries affects the four different parts of the calcaneus, and to choose between either procedure.

[Verifying the function of hepaticojejunostomies by scintigraphy of the bile ducts].

Thirty six hepatobiliary scintigraphies with 99mTc-Dimethyl IDA were performed in thirty patients with an hepaticojejunostomy one month to ten years after surgery. Twenty patients underwent surgery for biliary disease and ten for duodenal or pancreatic disease. In most cases (twenty three), the radionuclide study has been systematically performed to assess the scintigraphic pattern of a normal hepaticojejunostomy. In seven cases this pattern was abnormal. Four times the biliary enteric anastomosis was involved. Three times it showed an abnormal liver morphology. After an hepaticojejunostomy, hepatobiliary scintigraphy seems to be the only examination providing dynamic information for the biliary enteric anastomosis and the intestinal loop. But it sometimes is difficult to analyse in all cases, it must be the screening test in patients when symptoms occur after hepaticojejunostomy; but a percutaneous transhepatic cholangiogram cannot always be avoided.
