The methods of determining the length of the leg include direct measurement, relative measurement and so on.
1. Direct measurement: The patient takes a longer rope and fixes one point of the rope at the most prominent position of the outermost hip joint and another point at the tip of the inner ankle. Then the rope is tightened to mark the absolute length of one side of the lower limb by measuring the length of the rope.
2. Relative measurements: Since the limbs are in proportion to the growth of long legs means that the hands are also very long, you can stand against the wall, back straight, put down both arms vertically and then measured, mainly to see the wrist line position, to see the wrist line can be to what position. Body short legs long means more than the crotch. Conversely legs are not long did not exceed the crotch, indicating that there is no more than the crotch.
There are many other ways to determine the length of the leg, and to pay attention to safety when measuring.
