In the case of a squash, the force of external force crushes the skin, muscles, and surrounding tissue, as well as ruptures the blood vessels. The destroyed blood vessels cause heavy bleeding, which can lead to bruising and severe swelling within the wound. As a rule, it is the result of a blunt force, for example in road traffic accidents or in the home or in sports. In comparison to a cut, no sharp wound edges are visible and there are more and more abrasions. In addition, the risk of infection in breast-feeding is very high.


Crushing is most common in accidents involving high speeds or a lot of force, such as in traffic, at home or in sports. In a car accident, for example, the impact causes a high external impact of force and this leads to a massive entrapment in the tissue.

Even with entrapment when closing doors or windows, there may be crushes on fingers or hands. In sports, the dropping of sports equipment on the foot or body hits by thugs can lead to squashes. Quetschwunden often go in traffic accidents or serious falls with other injuries, such as cuts and fractures associated.

What is the difference between a sore throat and a lacerated wound?

The lacerated wound is similar to the crushing loss caused by a blunt force. The lacerated wound, however, is the result of an indirect pulling action which tears open the tissue and the vessels. The tearing leads to a heavy bleeding.

However, in contrast to the crushing shrinkage, there are no abrasions on the edges of the wound, but they are also irregular and can be found in both tissue bridges. Occasionally, pinched and lacerated wounds occur at the same time (crushed lacerated wound). It is true that in the course of time always comes to a crushing shrinkage and with further force to a crack wound.


The diagnosis can usually be made directly by the attending physician based on a detailed patient history of the accident and the appearance of the wound. The typical picture of a sore throat with the formation of a large, blue bruise, abrasions and swelling can quickly confirm the diagnosis of a sore throat.
In order to exclude possible complications or other injuries, such as fractures or organ damage, further examinations should be performed, such as X-rays, ultrasound or computed tomography (CT).

Accompanying symptoms

Due to the external violence and crushing of the tissue there is a bursting of the surrounding blood vessels. The destroyed blood vessels cause a massive hemorrhage, which can also spread to the tissue and it forms a hematoma. This bruise is usually noticeable as a bluish spot under the skin.

If, for example, the finger gets stuck in the window, it can cause swelling and bruising under the nail bed, a so-called subungual hematoma (below the nail). Patients also often complain of severe pain and high sensitivity to touch. As the skin contains many nerves also emotional disorders can occur. Depending on the location of the wound, it may also lead to movement restrictions.

Complications of a soreness

Depending on the size of the crushing shrinkage there is a high risk of infection. Injuries with equipment, tools or traffic accidents can cause bacteria to enter the wound and infect it. In addition, the bruise is a good breeding ground for bacteria. Therefore, extensive cleansing and disinfection in the treatment of squashed are very important. In addition, adjacent structures such as tendons and muscles can be injured and lead to movement restrictions and emotional disorders.

In the case of a soreness on the finger, which results in the formation of a subungual hematoma, the nail may become detached from the nail bed in the process. In very large and severe crushing, parts of the tissue can die and form so-called necroses. In the worst case, an amputation may be needed. An infection with the tetanus is also a complication, which is why there should always be adequate vaccine protection. With larger crushing injuries on the lower leg, a compartment syndrome can occur. Infection with bacteria such as Clostridium perfringens can lead to life-threatening gas gangrene.

Treatment / therapy

For smaller wrinkles that occur during housework or during sports, an acute treatment can quickly provide relief. It is important to immediately cool the wound to relieve pain and counteract swelling. In addition, an ointment dressing with Beta's Madonna or Voltaren can help with healing. The body part should be spared for a few days.

For larger wounds, a doctor or hospital should be consulted in most cases. For bleeding wounds, first and foremost, hemostasis is important to prevent the progression of bruising. This can be treated by means of strong compression. At the hospital, the wound is first cleaned and disinfected to reduce the risk of infection. Then she is inspected. In most cases, squashes are closed, so the wound does not have to be sutured. A sterile wound dressing is usually sufficient.

If it comes to an infection, the wound must be cleaned and checked regularly. For severe infections, antibiotics must be given and sometimes an opening and surgical cleaning under sterile conditions is necessary. If necroses (dead tissue) appear on the wound surfaces, they must be surgically removed immediately.

healing time

The healing time of wrinkles depends on their size and extent. As a rule, smaller wounds heal completely and without scarring within a few days to two weeks with good treatment.
For larger wounds, it can quickly lead to the occurrence of infections and complications that prolong the healing process. If the wound is not cleaned and treated regularly, a large infected wound may take several months to completely heal.

In addition, scars often remain behind. Patients with diabetes or vascular disease (PAD) often have a wound healing disorder. As a result, large crushing losses can not be closed and they must be cleaned and closed in several operations.

When do I have to go to the doctor?

Smaller wounds usually heal within 2 weeks and lead to no complications. Therefore, no doctor needs to be visited.
For large wounds, which lead to severe pain and swelling, it makes sense to visit a doctor. Even if it has come to a few days despite good cooling and ointment improvement, a doctor can help. Also with movement restrictions and emotional disorders.
If there is redness around the wound or the patient is experiencing fever this may be a sign of infection of the wound. In that case, a doctor should be consulted immediately. As a rule, it is sufficient to visit a family doctor. In addition, a general surgeon can help. The ambulance should only be called in absolute emergencies. Quetschwunden cure with good treatment usually without complications and there is no limitation of life expectancy.
