[Pelvimetry].

It has been shown that, in all the different ways of performing pelvimetry, use of computed tomographic techniques leads to a significant reduction in radiation doses. We describe a new method of pelvimetry, involving computed tomography consisting of two scoutviews. The results of this method are compared with the results of conventional technique ad modum Fernström, measured in 55 women. Both methods showed large inter-observator differences. No statistically significant differences between the methods were revealed but the anteroposterior outlet was slightly smaller with the CT-technique (mean 6 mm). The method is recommended, since it is easy to use, and the rate of ionizing radiation is low.

[Idiopathic benign non-infectious segmental vertebral sclerosis].

Idiopathic, benign, non-infectious, segmental, vertebral sclerosis is a self-limiting condition, which must be differentiated primarily from infectious spondylo-discitis and sclerosing vertebral metastases. The typical patient is a middle-aged, parous women with pain in the lower back region. Radiologically there is a characteristic half-dome shaped supradiscal sclerosis in the anterior and middle part of the affected vertebral body, which is always of normal height and there is never an abnormal paravertebral soft tissue mass. The erythrocyte sedimentation rate is normal. It is important to recognize this condition in order to avoid unnecessary examinations.

Femoral anteversion measured by ultrasonography and radiography. An anatomic investigation.

Radiographic and real-time ultrasound measurements of femoral anteversion were compared in an anatomic study of 20 dried adult femurs. The real anteversion (AV) angle was determined by biplanar radiography. In four ultrasound measurements, the linear transducer was kept either horizontal or tilted. The measuring lines were either the anterior tangent of the femoral head--greater trochanter or the anterior tangent of the femoral neck. With the tilted transducer, the correlation between the head-trochanter AV angle and the real AV angle was high (r = 0.9452), and slightly less when the anterior neck AV angle was used (r = 0.9142). The clinical relevance is that the tilted transducer technique with the head-trochanter tangent is recommended for AV screening in patients with clinical signs of increased femoral anteversion. In adults 8.5 degrees has to be subtracted in order to obtain an approximation of the real AV angle.
