[Angular measurements of the hindfoot in CT].

The absence of soft tissue superimposition on bone makes CT greatly superior to conventional radiographs, even using special views, for demonstrating the hind foot. Views derived from both methods are compared. Semicoronary and transverse planes have been defined in relation to specific points in the tarsus. In the semicoronary plane, the calcaneus-valgus angle varies from +10 degrees (valgus) to -10 degrees (varus) and the sustentaculum angle varies from 18 to 28 degrees. In the transverse plane, the plantar talocalcaneal angle is 60 degrees to 70 degrees and the calcaneal-cuboidal angle is 20 degrees to 35 degrees. These values are based on measurements of 62 normal feet. They are valuable for judging quantitatively posttraumatic deformities, displacement of fragments and operative results.

[Pathologic changes in the hindfoot angle following fracture of the calcaneus].

Forty fractured calcanei (13 without and 27 with involvement of the joint) were examined by CT and the angle of the hind foot measured. Following a typical compression fracture there is a negative calcaneus-valgus angle, i.e. varus deformity of the tuberosity fragment. The sustentaculum angle is increased. There are changes in the talo-calcaneal and calcaneo-cuboidal angles. The length ratio of calcaneus to talus is reduced. Reproducible measurements make it possible to compare the results of operative correction and of changes in shape following conservative treatment, e.g. during weight-bearing.

[Indications for computerized tomography of the wrist joint and carpal bones].

Twenty-nine patients with thirty-one fractures of the distal radius and persistent pain or disability had computed tomography of the radio-carpal and distal radioulnar joint. We found incongruity of the distal radio-ulnar joint in six patients. Ten patients had a rotational malalignment in supination. Seven patients suffered from rotational malalignment in pronation. The ability to quantify rotational malalignment and to have images of the degenerative arthritis following these disorders without superimposition aids in selecting surgical treatment.

[CT diagnosis of malalignment following distal radius fracture].

Examination of 29 cases of fracture of the distal radius with restricted motion or persistent pain in 22 patients showed that most had been caused by incongruity of the distal radioulnar joint or by rotational malalignment in supination or pronation. Imaging of the distal radioulnar joint without superimposition enables us to detect whether disorders of the joint facets are impeding movement. Exact knowledge of the malalignment aids in the planning of osteoplastic surgery.

[Radiologic diagnosis following compound fracture of the distal radius with special reference to computed tomography].

After complicated distal radius fractures with persistent symptoms, a variety of radiological methods may be indicated, including plain films, magnification views, examination under stress and arthrography. CT accurately differentiates abnormalities of the distal radio-ulnar joint and aids in deciding on surgical treatment. Demonstration of degenerative changes and of subluxations is much more satisfactory in the third plane, since there is no superimposition.

[Comparative studies of contractile heart function using impedance, echo-, radio- and apex cardiography].

89 patients (31 healthy subjects, 31 hypertensives, and 27 patients with coronary heart disease) were examined simultaneously by means of impedance (ICG)-, ultrasonic (UCG)-, radio (RCG)-, and calib. and diff. apex cardiography (cACG). There were found significant correlations between the ICG-, UCG-, and RCG-parameters, all describing the heart function in the auxotonic ejection phase. Whereas there were no significant correlations between the methods mentioned and the cACG. Of all investigated parameters in hypertensives only the quotient A/S of cACG is significantly increased compared with persons with healthy heart and circulation. In patients with coronary heart disease all the parameters of the auxotonic ejection phase are significantly decreased, the isometric contraction time and the quotient A/S are increased.

[The heart in hypertension].

After indications to the great epidemiologic importance of hypertensive heart disease and its relationship with the ischaemic heart disease several results are reported collected during the past 10 years by examinations of more than 500 patients for early diagnosis of cardiac insufficiency in hypertension. The methods of microcatheterization of the pulmonary artery and radiography have been used (even under ergometrical exercise) as well as the calibrated apex cardiography and the echocardiography. For the practising physician a classification of hypertensive heart disease with 4 phases or forms is proposed. The paper ends with a demonstration of the close relationship between prevention and treatment of hypertension as well as between hypertensive and ischaemic heart disease at the same time in a sense of the integrative role of heart insufficiency.
