METHOD FOR DETECTING THE POSITION OF SHIN BONES IN PROXIMAL AND DISTAL DEPARTMENTS Russian patent published in 2007 - IPC A61B6/00 A61B6/03 

FIELD: medicine, roentgenology.

SUBSTANCE: it is necessary to obtain axial tomograms of distal epiphysis of a thigh bone and a mortise joint, apply a tangent along posterior edge of femoral condyles, moreover, at axial tomogram of proximal shin department through the middles of external and internal tibial condyles one should apply percondylar transverse axis, and in frontal plane one should apply a tangent passing through the center of proximal fibular metaphysis and crossing percondylar transverse axis by forming an angle α, that characterizes the metaphysial shift degree of proximal tibial department against frontal plane; then through the middle of fibular caput's epiphysis one should apply an axis passing through the center of proximal tibial metaphysis by crossing a tangent and forming an angle β, that characterizes epiphysial shift degree of fibular caput against frontal plane, at axial tomogram of a mortise joint in sagittal plane through the middle of anterior and posterior surfaces of patient's ankle bone and the center of Achilles tendon it is necessary to apply longitudinal axis of ankle bone, and in frontal plane - a tangent passing at direct angle through the middle of longitudinal axis of ankle bone at forming the center of ankle bone, through the middle of internal ankle one should apply an axis passing through the center of ankle bone by crossing a tangent and forming an angle γ, that characterizes the shift degree of internal tibial ankle against frontal plane; then through the middle of external ankle one should apply an axis passing through the center of ankle bone by crossing a tangent and forming an angle φ, that characterizes the shift degree of external fibular ankle against frontal plane and at shift value of proximal tibial metaphysis ranged 0-10° and epiphysis of fibular caput ranged 20-40° against frontal plane it is possible to conclude upon correct position and development of shin bones in proximal department; at shift value of internal tibial ankle ranged 0-10° and external fibular ankle against frontal plane ranged 20-40° one may conclude upon correct position and development of shin bones in distal department.

EFFECT: higher efficiency of detection.
