Figure 3. The shapes of various stump-thigh relationships.

1. The difference between the M/L and S/C circumference is larger than the P/T circumference.
2. The difference between the M/L and S/C diameters is between 1 1/8 inch and 1 1/2 inch, and the S/C circumference is equal to the P/T circumference.
3. The difference between the M/L and S/C diameters is greater than 1 1/2 inch, and the S/C circumference is smaller than the P/T circumference.
