DEVICE AND METHOD FOR DETERMINING LOWER EXTREMITY SHORTENING Russian patent published in 2004 - IPC

FIELD: medicine; medical engineering.

SUBSTANCE: device has level unit, adjusting strip connected to the level unit with one end by means of hinge. The second end of the adjusting strip has graduated measuring scale connected to the level unit by means of threaded spring loaded rod. Adjusting nut is mounted on the upper end of the threaded rod. Angle between the level unit and the adjusting strip is measured by rotating the nut. Method involves arranged patient feet on horizontal plane, matching measuring points of the device with anatomical points under measurement and setting the level unit in horizontal position. The horizontal position of level unit is achieved by varying angle of level unit position relative to points under measurement. To do it, adjustable level unit end is rotated about its fixed end. The level unit position is fixed. Shortening value is determined from measuring scale.

EFFECT: high accuracy and reliability of the method; accelerated measurement process.
