FIELD: medical equipment; applicable in traumatology and orthopedics in treatment of injuries and diseases of extremities, particularly, devices for measurement of rotation deformations. SUBSTANCE: rotometer has body provided with scale, position indicator made in form of pointer with plumb hinged to body and position retainers. Body is made in form of plate with vertical recess for motion relative to axis and with horizontal recess for motion of pins. Position retainers are made in form of bent branches whose ends are located opposite to each other. Branches are located on different sides of plate and interconnected by axle, with pins secured at same distance from axle. Rotometer is secured at respective segments with help of wing nut installed on axle threaded end. EFFECT: increased accuracy of measurement of angle of crus rotation deformation and range of amplitude measurements of rotation motions in joints of upper and lower extremities. 3 cl, 4 dwg
