An orthosis is a type of bandage for the wrist and / or the entire hand. The orthosis is used to relieve the hand and, with regard to lunate malacia, is usually used when no operation has yet been performed. But an orthosis can often be used even after an operation.
Some orthopedic surgeons prescribe a cast to immobilize the hand, but this has many disadvantages:
My recommendation is to wear them in everyday life if you easily forget to take care of your hand (e.g. shopping, cycling, gardening) and otherwise take them off (e.g. while watching TV, etc.) and keep moving your hand without strain. (The same applies here: discuss this with the treating doctor beforehand!)
Orthoses are available in medical supply stores and sometimes also in pharmacies or even on the Internet. On prescription, the additional payment varies between 0.00 and 40.00 euros.
