What different ankle joint orthoses are available?
In the case of ankle joint orthoses, there are differences in the construction and the material used on the one hand and in the quality on the other. Simple orthoses can be purchased in sports stores, for example. Professional ankle joint orthoses, on the other hand, are usually only available from a medical supply store.
In terms of construction, a distinction can be made between rigid, semi-rigid and flexible orthoses. The rigid variants usually consist of two splints that surround and fix the ankle joint laterally. These are tightened with bands or straps.
This prevents any movement in the ankle joint except for flexion and extension, i.e. lowering and lifting of the foot. Rigid ankle joint orthoses are necessary after recent injuries to ligament structures. Semi-rigid orthoses, on the other hand, resemble a kind of stocking that is pulled over the foot and lower leg and tied up. This allows for greater mobility on the one hand and supports stability on the other. This type of ankle joint orthosis is used, for example, by athletes who want to carefully resume training after a recovered injury.
How does an orthosis work?
An ankle joint orthosis surrounds the joint and fits tightly there. Its firm elements have a stabilizing effect. This relieves the ligaments of the joint and provides protection against incorrect movements and, if necessary, pain relief.
The movements in the joint are guided by the orthosis and it is prevented from breaking out during movement. Compared to a bandage (ankle bandage), for example, orthoses therefore restrict the series of actions in favor of greater stability. A cast, on the other hand, achieves maximum stability but prevents any mobility. The ankle joint orthosis therefore offers a good compromise between mobility and stability and is therefore frequently used.
How do I put on an ankle orthosis correctly?
When fitting an ankle joint orthosis, care must be taken to ensure that it fits comfortably but still surrounds the joint firmly.Different settings can be made depending on the model. First of all, the heel support should be adjusted with the Velcro fastener so that the side parts adapt well to the joint. All other fasteners and straps should also be open and loose.
Then the ankle joint orthosis is applied. The foot should be in a 90 degree position. The foot is placed in the middle.
Now all Velcro straps are tightened alternately. First loosely and then somewhat tighter. Finally, the ankle orthosis should fit firmly without exerting too much pressure.
If the orthosis slips, it is either too loose or its fit is not suitable. If the orthosis is tight or there is a sensation of discomfort in the foot, it is too tight. Anyone who has difficulty putting on the ankle joint orthosis can get help from a medical supply store, for example.
