Measuring for the Xerosox® Waterproof Cast Cover
Step 1: Measuring Limb CircumferenceArm: Measure the circumference of the arm roughly 2 inches above (proximal to) the cast or bandage. If the end of the cast is very close to the elbow, measure mid upper arm (around the bicep). Leg: Measure the circumference of the leg just above the cast or bandage. If the end of the cast is very close to the knee, measure mid thigh. Please note: Do not measure around the cast but around the bare arm or leg as shown in Figure 1. |

Step 2: Measure LengthArm: Measure from the tip of the middle finger to where the circumference was measured in step 1. Leg: Measure from the back of the heel to where the circumference was measured. For younger children the full arm and full leg Xerosox® offer the best fit; measure from the mid bicep or mid thigh. Don't worry if the Xerosox® is longer than it needs to be. Move the extra length to the middle of the limb, the excess material will shrink in on itself when the vacuum is created. |

Step 3: Use Size Charts
Using the size charts select the Xerosox® size that is right for you or your patient. The circumference is more important than the length because it is critical for a good seal.
*Note the half arms and half legs are not normally used for children. Pediatric patients almost always use full arm or leg Xerosox®.
