The D'Osualdo Arcometer is a validated instrument for non-invasive measurement of KYPHOSIS and LORDOSIS.
The arcometer is a manual device made up of a ruled bar bearing three perpendicular arms: the first one is fixed at one end, the intermediate one is mobile on two axes and the third one mobile on one axis only.
The ends of the three arms identify three points through which a single circumference can be drawn. Using the arcometer we can measure the chord and the rise. These two values allow us to calculate the radius of the curve and Cobb angle by using a two entry table.
The instrument comes with a table to calculate the Cobb angle (current use to integrate the clinical examination).
The picture shows the arcometer working principle: note that, in order to make calculations easier, the intermediate arm has to be placed into the mid-point between the lateral arms.
Supplied with the user manual "D'Osualdo Arcometer" (code 01769).
