Definition – What is an orthosis?
An orthosis is a medical aid that is used to support functions of the musculoskeletal system, especially joints. They are used after operations, accidents or in cases of congenital malpositions and serve to secure or restore posture. Orthoses are available for all major joints such as the knee or wrist, but also for the back. In most cases, an orthosis is a splint made of plastic and various ligaments that allow for guidance and stabilization on the inserted body part.
Why do you need an orthosis?
The possible field of application is very large, as these can be used for different reasons and on a variety of body parts. A common reason why an orthosis is needed is injuries to joints or ligaments. A frequently occurring injury is a torn cruciate ligament in the knee, which can be contracted while skiing or playing soccer, among other things.
Often a knee orthosis is then prescribed for a few weeks to keep the knee joint stable from the outside and prevent further injuries. In older people, signs of wear and tear of the joints (arthrosis) or bone loss (osteoporosis) are often the reason why the use of an orthosis is indicated. These can help to stabilize parts of the body and thus maintain the quality of life.
People with weakness of dorsiflexion of the foot, for example as a result of a herniated disc, can be assisted in walking with the aid of a special orthosis. Orthoses are also an important part of the therapy for many diseases in children. Congenital deformities of the hip or feet are the most common reason why orthotic treatment is necessary.
Through timely and consistent therapy, a malposition can often be corrected so that the child can learn to walk normally. Even in cases where a malposition can no longer be corrected or cannot be completely corrected, orthoses can often at least provide a stabilizing aid. Finally, orthoses are also sometimes used by healthy people to prevent injury or overloading. Competitive athletes, for example, from the field of running, occasionally use orthoses for the legs to support and thus protect joints and ligaments.
