Wrist brace AM-OSN-U-17


Distal Radial Ulnar Joint (DRUJ) Instability

Distal Radial Ulnar Joint (DRUJ) provides not only supination and pronation of the forearm, but also is crucial to the grip strength and lifting capabilities of individuals.

Two forces act in the forearm:

- axial loading, which is created by the muscles to produce gripping,

- transverse force,, which runs from the hand to the radius to the ulnar head and is the force of gravity against which the arm has to lift.

During forearm motion, the distal radial ulnar joint (DRUJ) moves synchronously with the proximal radioulnar joint. Due to that fact, any injury or deformity involving the radius or ulna can alter the function of both joints.

Long-term using the DRUJ, including lifting heavy objects and stressed rotating forearm may result in distal radial ulnar joint (DRUJ) instability. Furthermore, systematic stress of the joint, may lead to ulnar styloid and distal ulnar fractures.

Most stress and dislocations of distal radial ulnar joint (DRUJ) are caused in daily activities such as physical work or gymnastic exercises.

Symptoms of DRUJ instability and stress of ulnar styloid are pain and limited motion with lifting the objects disability.

Usually treatment bases on non-invasive procedures, including stabilization and pharmacology. In more serious cases, surgery is crucial.

The best method for preventing distal radial ulnar joint (DRUJ) instability is stabilization with our universal ulnar abutment brace AM-OSN-U-17 with special ulnar styloid support. This brace is also excellent solution in non-invasive treatment and after surgeries.

Product’s description

Gwarancja wodoodporności

Elastic and universal gel wrist wrap AM-OSN-U-17 is a part of 4classic group and it’s made of innovative UniPren. It is universal 3-layered fabric made of external elastic polyamide self-gripping layer and internal neoprene foam with elastic jersey. Our fabric is soft and elastic and not knitted, what prevents skin against the skin abrasions in the compression zones. Self-gripping function of UniPren allows to fit the brace precisely.

Wrist brace AM-OSN-U-17 is waterproof and can be used in water and it’s easy to maintain.

Ulnar abutment AM-OSN-U-17 with ulnar styloid support is open, anatomic-shaped and easy to putting it on.

The brace is equipped with aluminum palmar splint which is malleable for custom fit.

Special Velcro strap improves the comfort of using the brace.

Additional internal patient assist strap allows to putting the brace only with one hand!

What is more, our ulnar abutment brace AM-OSN-U-17 is equipped with removable silicone pad providing support for ulnar styloid. Due to this fact, the brace not only stabilizes distal radial ulnar joint (DRUJ), but also supports head and ulnar styloid, preventing stress fractures.
