Use this guide with the OrthoH2O waterproof cast kit selected for the patient. OrthoH2O uses a water-resistant tubular stockinette beneath fiberglass casting tape. The stockinette is doubled for proper thickness, and the correct short arm, long arm, short leg, or long leg cast technique is then used.
Professional-use note: Cast type, limb position, molding, weight-bearing status, and duration of immobilization should be determined by the treating healthcare professional.
Waterproof cast materials are applied differently from traditional cast padding, and some doctors or cast technicians may not have used OrthoH2O before.
Please send or show this page and the application video to your doctor or cast technician before the cast is applied. A few minutes reviewing the technique can help make sure the waterproof liner is prepared and applied as intended.
It is the purchaser/patient's responsibility to make sure the treating office receives these instructions before application. Do not assume the office has worked with this specific waterproof system before.
The treating healthcare professional remains responsible for deciding whether the material is appropriate for the patient and for the actual clinical application of the cast.
The OrthoH2O stockinette can be handled during preparation. The sealed-pouch warning applies to the fiberglass casting tape.
The four OrthoH2O cast kits use the same waterproof-liner concept. The limb-specific cast shape and fiberglass application differ by cast type.
For general fiberglass tape wrapping, molding, and finishing technique, also see How to Apply Orthopedic Fiberglass Casting Tape.
The OrthoH2O stockinette is doubled so it provides the proper thickness.
For: OrthoH2O Waterproof Short Arm Cast Kit
Use this section for wrist, hand, and forearm short-arm cast applications. Apply the doubled OrthoH2O stockinette first, then complete the fiberglass short-arm cast using the treating professional's required position and molding technique.
For: OrthoH2O Waterproof Long Arm Cast Kit
Use this section for long-arm applications extending above the elbow. Apply the doubled OrthoH2O stockinette first, then complete the fiberglass long-arm cast using the prescribed elbow position and molding technique.
For: OrthoH2O Waterproof Short Leg Cast Kit
Use this section for below-knee ankle and foot cast applications. Apply the doubled OrthoH2O stockinette first, then complete the fiberglass short-leg cast using the prescribed ankle position and molding technique.
For: OrthoH2O Waterproof Long Leg Cast Kit
Use this section for long-leg applications extending above the knee. Apply the doubled OrthoH2O stockinette first, then complete the fiberglass long-leg cast using the prescribed knee and ankle position and molding technique.
For OrthoTape's customer-care protocol, use a hair dryer with cool or low airflow after every wet exposure and continue until the cast is completely dry.
Do not rely on air-drying alone. A waterproof cast will take longer to dry without assisted airflow, especially in areas where air does not circulate freely. Do not use a high-heat setting.
A walking cast heel can reduce airflow around the bottom of the cast. This makes the plantar surface and the area immediately around the walking heel more difficult to dry.
Direct cool or low airflow carefully around the base of the cast and around the walking cast heel until these areas are completely dry. Do not assume the cast is dry just because the outside surface feels dry.
Yes. Waterproof casting materials can be unfamiliar to some offices. Send or show this page and the appropriate application video before the cast is applied. It is the purchaser or patient's responsibility to make sure the treating office receives the instructions.
No. OrthoH2O uses a water-resistant tubular stockinette that is applied and doubled for the proper thickness before the fiberglass cast is completed. The clinician should review the OrthoH2O application video before use if they have not used the system before.
A trained healthcare professional or cast technician should apply the system. The treating professional remains responsible for cast selection, limb position, molding, weight-bearing instructions, and clinical care.
OrthoH2O is intended for waterproof casting applications, but swimming, bathing, showering, and other water exposure should only occur when the treating healthcare professional approves it for that patient and injury.
For OrthoTape's customer-care protocol, yes. Let excess water drain, then use a hair dryer on cool or low airflow and continue until the liner and cast are completely dry. Do not use high heat and do not rely on air-drying alone.
A walking cast heel can restrict airflow around the plantar base of the cast. Direct cool or low airflow around the base and heel assembly and give that area extra drying time. Do not assume the inside is dry just because the exterior fiberglass feels dry.
No. Keep each fiberglass casting-tape pouch sealed until the clinician is ready to activate and apply that roll. Opening the pouch exposes the moisture-activated resin to humidity and can begin curing.
