Determine nail diameter
To determine nail diameter, position the image intensifier for
an AP view of the femur at the level of the isthmus. Hold
the radiographic ruler perpendicular to the femur and posi-
tion the diameter tabs over the isthmus. Read the diameter
measurement on the tab that fills the canal.
Note:
Take into consideration that the ruler is not at the
same level as the femur. This will affect the accuracy of the
measurement.
