Distal radius fracture is one of the most common type of bone fractures. It occurs at the end of the radius bone near the wrist. It happens in a sport activity, car or skiing accident. It is a result of falling on an outstretched or flexed hand. When you suffer from direct impact to the palm, it is called Colles fracture. If you are falling on a bent wrist, we call it Smith’s fracture.

Colles and Smith’s fracture

Immediately after injury the wrist is painful and swollen. The other symptom of the fracture is deformity and limited motion.

If the fracture is stable and doesn’t require the surgery, the professional orthopedic wrist splint AM-OSN-L-04 is applied.

UniPren™ is a universal 3-layer material consisting of an external elastic polyamide cover knit with a self-adhesive function, an internal neoprene foam core and an elastic jersey cover knit. This material is characterized by softness and very high flexibility. A very important advantage of this material is the fact that it is not a knitted product, it does not have thick fibers, so that the weaves of the material do not imprint on the patient's skin and do not cause abrasionsin places of high compression. Products made of UniPren™ are the strongest and most effective stabilizing orthoses available on the market. Self-adhesive function, the raw material makes it much easier to use.


Flat aluminum stays

Aluminum stays are made of a special aluminum alloy that guarantees proper stiffness with minimal weight. They have rounded ends to prevent the damage of the product and come in various widths and thicknesses. The level of stabilization of the orthopedic device is defined by proper selection of the width and thickness of the aluminum stays. The stays can be pre-profiled or flat. They do not adapt to the shape of the patient's body, an individual adjustment of the orthosis is required by proper bending of the aluminum stays in the product. Thanks to this function, it is possible to correct the position of the patient's body or the secured joint.

Plastic stays

They come in various widths and thicknesses, are made of various types of plastics, such as polyamide, ABS or acrylic, and these features determine their stiffness. Thanks to their design, they are resistant to water, moisture and sweat. Products equipped with them can be washed without having to remove them from the orthosis. Our plastic stays work only in one direction, perfectly stabilize the laterally protected part of the body, adjusting to it at the same time and have a memory function, thanks to which they always return to their original shape. This function causes the stays in the orthosis to stabilize the swollen limb immediately after the injury and after the swelling has come off. The plastic stays cannot bend and that is why, they cannot correct the body posture or the secured joint.
