Radiologically assisted gastrostomies or enterostomies are a reliable and effective form of treatment even amongst difficult patients. The results and complications are comparable to those from endoscopic procedures.

Femoral anteversion, anteversion of the acetabulum and tibial torsion of 47 patients with idiopathic osteoarthritis of the hip were determined by computerized tomography. From all these parameters only the anteversion of the acetabulum showed differing values in hips with and without osteoarthritis. There was a considerable range at the individual measured values in all parameters and differences between the male and female groups could be found in femoral anteversion and anteversion of the acetabulum.

With a technical success rate of 93% and a clinical success rate of 85% dacryocystoplasty is a non-operative alternative for treatment of epiphora caused by obstructions of the nasolacrimal duct system.

The CT-measured urine samples as evidence of renal excretion of orally or rectally applied Gastrografin are not reliable for the detection of leaks from the GI-tract.

Since 1984 the law concerning safety belts has been implemented; this paper deals with the findings in 386 victims of motor accidents who were x-rayed between 1981 and 1989. Minor injuries have been ignored. The number of passengers wearing belts increased by 30% after 1984. The number of passenger injuries did not decrease. Injuries directly caused by the belts included a small number of fractures of clavicles, the sternum and ribs and one pelvic fracture, one serious abdominal injury with tearing of the mesenteric artery and one ruptured spleen. An indirect result of wearing seat belts was a marked increase in cervical whiplash injuries and some increase in thoracic vertebral fractures. None of the belt induced injuries proved fatal. Amongst those using seat belts there was a significantly lower fatality rate and injuries causing prolonged disability. In particular, using seat belts, serious injuries to the skull and brain were reduced by 80%. Similarly injuries to the abdomen, the odontoid, pelvis and hip joint were greatly reduced. The advantages of wearing a seat belt greatly outweigh the disadvantages.
