Lower-extremity support AM-KD-AM/2R

Knee hyperextension

Knee hyperextension is also called “genu recurvatum” and occurs when the leg excessively straightens at the knee joint and the knee has malalignment on the sagittal plane.

It can be many reasons of this condition: genetic disorders (e.g. Ehlers–Danlos syndromes), postural conditions in children (flat feet, scoliosis) or neurological disease such as stroke or meningitis. Regardless of the reason, hyperextention position puts stress on the knee structures and the back of the knee joint. What is more, knee joint is important while walking. Excessive knee extension makes the gait pattern poor and puts the stress on pelvic and spine.

Excellent solution for gait pattern improvement in case of excessive knee extension is our hyperextended knee brace NEURA.

Product description

Knee brace NEURA is perfect product for everyone who suffers from hyperextended knee. The brace prevents against excessive knee extension, but does not limit the flexion and improves the gait pattern.

Our hyperextended knee brace NEURA is made of lightweight, skin-friendly fabric ActiveDistance II&ntade;.

NEURA is equipped with 2 side anatomic-shaped splints with dynamic hyperextension system. Splints provide knee alignment on the sagittal plane and range of motion in every 20 degrees. What is more, dynamic hyperextension spring reduces excessive extension and absorbs shock on the knee tissues.

NEURA maintains the knee in alignment on both sagittal and frontal planes. It improves gait cycles including stance and swing phases. The most important feature of NEURA knee brace is reducing the knee hyperextension but not limiting the flexion. Also, there is possible to adjust required range of motion according to therapeutic needs.

Our hyperextended knee brace NEURA has wrap around design and is easy to apply for everyone.

Wrap around design and friendly for skin fabrics allow moisture to be wicked rapidly to the outer surface and keep the skin dry.

In case of neurological disease such as stroke or meningitis, the sooner physiotherapy treatment the better. Early using of our hyperextended knee brace NEURA in proper gait learning, keeps the lower limb in good posture and improves the gait pattern. This solution prevents against the pathological compensations in trunk and pelvic area.

LOWER LIMB ORTHOSIS AM-KD-AM/2R is a product used to limit the mobility of the knee joint after surgery, treatment and healing of knee joint injuries and as immobilization if the patient is qualified for surgery. All diseases causing deformations within the lower limb exclude the use of the AM-KD-AM/2R brace due to the risk of permanent damage. In order to stabilize the limb in the case of deformation and degenerative changes, it is recommended to use professional steel orthoses, made in specialized orthopedic centers.

Purpose of use

MATERIALS

ActiveDistance II™

ActiveDistance II™ is an active 3-layered fabric made of non-elastic polyamide self-gripping layer, comfort foam and cotton terry. The last one layer is responsible for maintaining your skin dry. This material is skin-friendly and has the Oeko-Tex Standard 100 certificate. Self-gripping function of ActiveDistance II™ allows to fit the braces precisely.

STIFFENINGS

Splint 2R with anti-hyperextension mechanism

Orthopedic splints 2R are the strongest and most developed orthopedic splints in the Reh4Mat offer. These biaxial splints are equipped with a ratchet mechanism and a shock absorbing spring. The splints are made of a specially hardened aluminum alloy, additionally secured with a durable powder coating. Thanks to this structure, they are light but still rigid and resistant to water and patient sweat. They are equipped with drop locks for precise regulation of joint mobility in every 20 degrees, made by means of special steel rivets. In addition, the drop lock has an external plastic cover, securing the rivets against accidental falling out, and unauthorized adjustment. On the inside, the drop lock has an oval velcro fastening, which allows to attach anatomically shaped soft 3D pads to the drop lock that relieve and laterally stabilize the knee joint. The biaxial mechanism of the orthopedic splint is the closest to the anatomical movement of the knee joint, thanks to which the orthosis does not move on the limb during use, and therefore very precisely controls the angle of flexion and extension of the joint. The ratchet mechanism additionally supports the flexion and extension of the splint and always positions its arms symmetrically. When using a splint, always lock the flexion and extension angles symmetrically on both sides, otherwise the ratchet mechanism will be damaged. A very important element of the 2R splint is the anti-shock spring, securing the knee against hyperextension, absorbing shocks and the joint tissues.

PADDINGS

3D supports

3D relief supports are independent technical solutions to relieve the rigid elements of a given orthosis. These elements are made of supporting foams or EVA foam. These foams are connected with various types of skin-friendly materials and materials with an adhesive function. These pads have the appropriate shape and color adapted to the type of orthosis. They relieve both metal elements of orthoses, such as splints, stays, underwires and orthopedic drop locks, as well as other elements that should not come into direct contact with the patient's skin. These pads have an anatomical shape and are made of comfortable foam with proper hardness and elasticity, guaranteeing the proper therapeutic effect.
