Ankle sprains are common injuries that you can suffer either practicing a sport or with a simple fall in the street. At first you may think that they are easy to heal, but you have to take into account several aspects such as a good bandage, a time of rest and a good subsequent rehabilitation, and is that otherwise, you can suffer sequelae of the injury as instability when walking or chronic pain.
There is a wide variety of bandages and materials available to make a functional bandage, depending on the severity of the injury or the affected area: elastic adhesive bandages, non-adhesive bandages, cohesive bandages, pre-tape bandages, scissors, foam rubber…
Cohesive elastic bandages are coated with a thin adhesive mass on both sides that makes it adhere to itself without sticking to the skin. They are breathable, waterproof, elastic and comfortable, and because they stick to themselves, there is no need to use adhesive tape.
Crepe bandages are non-adhesive elastic bandages, recommended to make a compressive bandage to promote venous return or when there is an inflamed area. They can be washed and dried, are reusable and do not lose their elasticity.
In a reductionist way, it is typical for us to speak of elastic bandages to refer to those that apply pressure during rest and exercise, adapting to the changing diameter of the calf, while we consider them inelastic bandages when their pressure at rest is low and increases in peaks with muscle contraction. If we only place a bandage of one type, elastic or inelastic, this may approximate its in vivo behavior. However, as we will see below, a bandage is more complex than a bandage.
The former is an inherent characteristic of any bandage. Any bandage placed on a leg will be a multilayer bandage, even if we only apply one bandage, as there will always be some overlap between layers.
If the bandage is not very stiff, there are no pressure peaks on movement, as it adapts to changes in the shape of the calf, with little resistance to increased muscle volume. The pressure under the bandage in these cases does not vary much between rest and activity (lower Dynamic Stiffness Index).
– Apply the bandage firmly, without being excessively tight and fix it with an adhesive tape normally. You can also use an adhesive tape, a bandage clip or simply tie a knot if you think it is necessary at the time.
To apply such a bandage keep the rolled part over the injury and the unrolled part toward the injury. Twist twice with each twist. Bandage from the inside to the outside and finish with a final straight line to secure the bandage.
If the bandage is to be applied to elbows or knees, the joint should be slightly flexed. The bandage is applied in the shape of a figure of eight and should be extended along the injured joint.
Normal bandages that when folded take the shape of a triangle. They are used as large dressings, as are slings. To contribute to the support of a limb or to keep the bandage in place, as in the case of immobilizing a fracture. Clothing such as scarves or T-shirts can also be used to make a triangular bandage, if necessary.
Bandage in 8
As a procedure or technique, it consists of wrapping a part of the body that is injured for various reasons. Currently its most frequent use is to cover skin lesions and immobilize osteoarticular injuries. But it is generally used in the treatment of wounds, hemorrhages, contusions, sprains, dislocations and fractures. It is a specific technique that allows maintaining certain functionality of the injured area without damaging it. Applied as a therapeutic technique, it aims to selectively and mechanically limit the mobility of a joint in the direction of movement affecting the injured structures of the peri-articular tissues.
Used to exert a progressive compression at the level of an extremity, from the distal to the proximal part, in order to promote venous return. It is also used to limit the movement of a joint in the case of 1st degree contusions and sprains.
The first turn is made with a 45º inclination towards the root of the limb, the second one with an inverted inclination (45º in the opposite direction to the previous one), the third one like the first one, but advancing a few centimeters towards the root of the limb… thus, in a back-and-forth movement, the bandage is completed, which at the end has the appearance of a “herringbone”.
