Femoral torsion analysis

Femoral torsion analysis is used to assess the alignment of a femur post surgery. If one side has been operated on it can be compared to the non-operated side.

Method

žSuperimpose axial images of:

  • —femoral heads
  • —beck of femurs
  • —femoral condyles

žDraw a line from the centre of the femoral head through the axis of the femoral neck, and draw another line along the posterior borders of the femoral condyles. Then measure the angle of these two lines.

Analysis

žNormal antetorsion values are considered to be 15-24°. These calculations and selected points can be very user depenedant.
