DELTA LEG N

The delta-leg is an original tool for lower limbs heterometry evaluation. It was designed to overcome the repeatability limits of traditional non-evaluation invasive methods, until now available, in particular the blocking method and the tape measure.
The tool consists of a bar on which two orthogonal platforms are applied: one is fixed and acts as a reference, the second is movable along the longitudinal axis of the bar and is equipped with a pointer which indicates the numerical value of the heterometry, positive or negative, on a millimeter scale placed on the surface top of the bar, with the “zero” value corresponding to the platform reference. In the carry-case version the instrument is equipped with removable footboards to reduce the footprint.
Dimensions: 45 x 25 x 22.5 h cm; Weight: 1.25 kg

FOR MEASURING THE LENGTH (HETEROMETRY) DIFFERENCE OF THE LOWER LIMBS

To measure, the patient is positioned supine and well aligned: head aligned with zenith nose, trunk aligned, lower limbs parallel with zenith positioned kneecaps. The operator therefore makes sure that the instrument has the longitudinal axis well aligned with the legs. Then he proceeds by placing the fixed platform next to the left foot, exerting moderate pressure to ensure good adhesion to the whole plant, and in particular to the heel. He approaches then the right, mobile platform, exerting equal pressure. The difference, on the millimeter scale, can be read at this point, or after removing the instrument (taking care not to alter the relation between the platforms). In case of retraction of the Achilles tendon we will only be able to measure functional heterometry.
