Bauerfeind RhizoLoc OA

Immobilization and relief of the carpometacarpal and metacarpophalangeal joint of the thumb

The RhizoLoc OA secures the thumb and index finger in a defined position and immobilizes the carpometacarpal joint and metacarpophalangeal joint of the thumb. Grasping movements are guided and strain is reduced.

In addition to chronic symptoms caused by osteoarthritis, this orthosis can also be used in cases of arthritis or following injuries and surgery to support functional treatment measures to achieve pain relief and mobilization.

Never expose the product to direct heat (e.g. heating, direct sunlight, storage in a car), as this can damage the material. This can affect the effectiveness of the product.

Regular care ensures an optimal effect.

1. Please close all fasteners and wash the orthosis by hand at 30 °C using a mild detergent or washing-up liquid. All components can remain on the orthosis.

3. The product is not suitable for tumble drying. Instead, use a towel or let the brace air dry.

An active life with osteoarthritis of the first carpometacarpal joint

The RhizoLoc OA immobilizes the carpometacarpal joint and metacarpophalangeal joint of the thumb and provides patients suffering from osteoarthritis of the first carpometacarpal joint with relief during everyday activities involving the inferior pincer grasp and the pincer grasp. Thanks to its stabilizing effect, it supports functional treatment measures to achieve pain alleviation and mobilization, and promotes maintaining the ability to work. In addition to chronic symptoms caused by osteoarthritis, this immobilizing thumb orthosis can also be used to reduce strain in cases of arthritis or following injuries and surgery.

A handy design

The new RhizoLoc OA is characterized by its patient-friendly design to encourage constant wearing, as soon as symptoms occur, and to support grasping movements. The narrow plastic brace, which features a reinforced midsection, is lightweight, perforated for air-permeability, and lies comfortably against the hand, thanks to its rounded edges. Two adjustable straps with holes ensure the product can be individually adjusted to fit the palm and wrist circumference. Patients can put on their RhizoLoc OA with one hand like a wrist watch, and secure the strap via a clip. The thumb strap provides additional support. It is securely tightened below the mobile interphalangeal joint. The strap’s soft Velcro velour is self-engaging and thus ensures that it protects clothing and surfaces. Particularly convenient: the RhizoLoc OA can be wiped and does not need to be removed when under running water.
