Lower-extremity support AM-OSK-ZJ/2RA


Product description



They are dedicated for patients to lighten the medial or lateral side of the knee joint. 3 points system allows to lighten articular surfaces of the femur and tibia, to reduce pressure on injured articular cartilage and decrease irritated pain receptors, which is maximum during the midstance (MST). Reducing the stress on the condyles helps to set the articular surfaces adequate against each other, what prevents knee valgus or varus.



How the 3 points system works

The first support point is the sleeve connected with splint, which stabilize the brace on the thigh on the stressed side (medial or lateral).
The second support point is the sleeve connected with splint also, which stabilize the brace on the shin on the stressed side (medial or lateral).
The third one is the spiral strap connected with the hinge and 2 straps above and under joint axial (on the femur and tibial condyles) – this solution reduces 50% pressure straps on the shin and thigh on the opposite site to supported.
Key element of the 3 Points System is the hinge. The polycentric hinge with edge and rotation movement during knee flexion facilitates maintenance the hinges in the knee axial.

Single splint knee brace AM-OSK-ZJ/2RA is the professional medical device, which increases the gait quality and is the support in rehabilitation of the locomotor system. It is made of a structural material ProFit, what means professional fitting. This is a 2-layer fabric, perfectly fitting patient’s body, stretching in all directions and modelling the limb- creating, so-called, the second skin. The external side of this textile contains spandex, which is responsible for precise compression and limb fitting. Also, it reduces the muscle vibrations during the physical activity. The internal membrane is made of microfiber, cotton and elastin, what prevents to perspire, and is very gentle for the skin. The brace is equipped a diagonal dynamic spiral force strap tightens when the knee is extended, it resists valgus forces and minimizes axial rotation. What is more, adjustable tibial strap provides tibial capture and improved suspension. It consists also of single splint 2RA with ROM adjustment (flexion 75°, extension 15° and immobilization in 0°). The brace stabilizes knee joint and prevent the valgus. It is highly recommended in knee degeneration, MCL injures connected with knee instability.

AirSanmed isn’t elastic what provides excellent stabilization. The skin has contact with cotton terry with Oeko-Tex Standard 100 certificate. There is semi-rigid perforated foam EVA inside that protect the skin against the metal splints influence. External side of the fabric is perforated medical laminate with antibacterial properties of Silver Zeolite. It provides long-term efficacy and prevents against the most dangerous infectious microorganisms such as MRSA and E.coli. AirSanmed is accordance with Health Minister`s ordinance of 3 November 2004 and Council Directive 93/42/EWG of 14 June 1993.

Purpose of use

AM-OSK-ZJ/2RA brace should be applied in cases of:

  • knee dislocation,
  • knee twist and sprain,
  • side instability of the knee joint,
  • knee ligaments injures – especially MCL and ACL injury,
  • knee ligaments reconstruction,
  • other surgeries (orthopedic),
  • excellent prophylaxis in sport.

Splints 2RA Precision

Splints 2RA PrecisionSplints 2RA Precision are a double axis anatomic splints which reflect the knee movement and during performance do not change their position towards the joint axis. Splints 2RA are double axis polycentric splints, with coupling mechanism with two main conductive elements which move of parabolic tracks. Such splints are mainly used in all knee joint braces and, apart from angle adjustment, the high lateral knee stabilization is very important. The splints are manufactured with high quality of sanded aluminium, durable cover which what makes splints neutral to the influence of sweat and salt. Flexion and extension angle adjustment is possible with special allen screws. Every brace is equipped with special Allen key which is necessary for adjustment. Anatomic splints provides hyperextension block, 30o, 55 o, 75 o, 95 o i 110 o flexion and 15 o or 75o extension. The angle adjustment clock is secured from manipulation by unauthorized people. Standard length of the splints is: 290 and 390 mm. The splint and its design are patented in European Union by Reh4Mat company.
