title: [Orthopedic radiology of the lower limbs. The two-dimensional "Complete Angles Lengths" technique (author's transl)].
abstract: The "Complete Angles Lengths (CAL)" is a new technique enabling geometrical definition of the lower limbs (angles and/or lengths) by the use of different reference points. Normal equipment can be employed, with or without radio control, and with ampliphotography if necessary. Localised orthoradiographs are performed through a fine metallic grid that can be made by the radiologist. Magnetic bands containing the programme for calculation are introduced into a packed calculator, and results are obtained automatically after feeding the measurements taken from the films into the machine. If the mode of employ is respected, the precision of the CAL is equal to or greater than that obtained with conventional methods.
