This is a medical-grade orthopaedic brace that incorporates rigid structural support. Braces and orthoses built with rigid components are usually covered under Canadian extended health benefit plans (e.g. Sun Life, Manulife, Canada Life, Blue Cross, Green Shield Canada) when accompanied by a valid prescription from your physician or nurse practitioner. It may also qualify as an eligible medical expense under the CRA's Medical Expense Tax Credit. We're happy to prepare an itemized estimate for your insurer — use Get an Insurance Estimate for this item, or add several to your cart and request one for everything at once. No charge, and it's not an order. Coverage details, annual limits, and prescription requirements vary by plan, so please confirm your specific benefits with your provider and keep your prescription and itemized receipt for your claim.

• Wash RHIZO-HiT gently in lukewarm water (30 °C) with mild detergent, then let it air-dry and do not place it on a radiator
• Do not dry it in the tumble dryer, on the heating or in the microwave
• Please close the hook-and-loop fasteners when doing so and take care not to accidentally change the individually moulded aluminium reinforcement by bending it

Sporlastic prints these steps in the instructions for use supplied with the product.

• RHIZO-HiT® can be worn on the left or right side.
• Close the end of the thumb tube before putting it on so that the opening encloses your thumb firmly but still comfortably.
• To achieve an optimal fit on the thumb, the hook band should lie fully on the velour without protruding at the edge.
• Slip the affected thumb into the brace. The lateral widenings on the strap prevent the strap from slipping out of the deflection loop, thus enabling easy entry.
• Grasp the non-elastic strap at the hook-and-loop fastener surface with thumb and index finger and fix RHIZO-HiT by closing the strap at the wrist.
• The deflection loop allows a controlled pull of the strap with little effort to stabilise the support on the wrist.
• Adjust the tension of the strap in such a way that you continue to feel comfortable wearing the brace with a noticeable stabilisation of the thumb and wrist. It may be necessary to readjust the hook-and-loop strap around the thumb.
• The illustration in the instructions for use shows the correct fit of RHIZO-HiT.
