Cosa Active/Junior hip abduction orthosis

Inconspicuously effective

The Cosa Active/Junior, a hip abduction orthosis, can be worn from childhood into adulthood. Scissor gait (also called crouch gait) is typically seen in various types of infantile cerebral palsy; this orthosis prevents crossing of the knees and allows for more stable standing and sitting thanks to the abduction pads.

For all users of this orthosis, the improved pelvic symmetry, improved trunk control, and increased freedom of knee movement supports a more physiological gait. Users of all ages will need to expend less energy to cover greater distances while wearing the Cosa Active/Junior. For patients in wheelchairs, wearing this orthosis will not only gain a wider seating position, but also gain greater freedom for their hands, making it easier to eat, play, write, or use electronic devices.

The orthosis can also be easily worn with lower leg orthoses such as an AFOs. The Cosa Active/Junior is also helpful for wheelchair users, as the orthosis makes additional wheelchair abductors unnecessary.

Zipper for easy donning and doffing

The Cosa line includes the Cosa Active and the Cosa Junior. While the latter covers sizes 80-116 (this corresponds to a body height of 74-122 cm) and does not feature a zipper, the Cosa Active is available in size 128 to unisex size L (women’s 46 and men’s 54).

Abduction pads

The abduction pads are fitted inside the extra padding pouches sewn into the trousers above the knee. The pads act as an artificial gap between the knees, thereby facilitating a more stable gait pattern. An orthotist can individually adjust the pads.

Individually positionable straps

The individually adjustable straps stabilise and secure the pads and strengthen the outward position.

Soft, breathable material

The Cosa Active/Junior is made of a stretchable, breathable material which is comfortable to wear and helps minimise perspiration. The trousers are easy to clean and are machine washable at 40°. The starter set contains two pairs of trousers and a pair of abductors for regular changing and washing.

Cosa Active / Cosa Active Junior

Whether congenital or acquired through trauma, there is often a misalignment of the hips, independent of the specific type of disability. Disorders of a spastic nature in particular often lead to increased adduction of the thighs. The result is a collision of the knee joints and the so-called scissor gait associated with this.
