The term “trauma” comes from Greek and means “injury, wound.” On the one hand, doctors use it to describe a harmful (traumatic) impact on the body. This could be an accident or psychological trauma, for example. On the other hand, the resulting damage is also considered a trauma, such as a
Trauma is classified as either mono- or polytrauma, depending on the number of organs and tissues affected.
Mono-trauma (mono = single) refers to an injury to a single organ, which in most cases is not life-threatening. This is primarily because the circumstances of the accident in cases of poly-trauma are generally much less severe than in cases of mono-trauma. However, there are also very severe and life-threatening single injuries, for which the term “barytrauma” (“bary” = severe) has become established. Examples of life-threatening single injuries include:
The life-threatening nature of these single injuries stems, for example, from the importance of the affected organ (traumatic brain injuries) or the potential for massive blood loss, which can reach considerable proportions (pelvic injuries).
“Polytrauma” refers to a severe, simultaneous injury to multiple organs. It is a multiple injury and, as the name (“poly” = many) suggests, affects several areas of the body or organ systems. Polytrauma is fundamentally a severe and life-threatening condition in which either all of the injuries combined or a single one of them is life-threatening.
There are many different types of trauma. What they all have in common is the application of force to the body, which endangers physical integrity. This force can be broadly divided into physical and psychological violence.
Physical violence includes:
- mechanical
- physical, or
- chemical
effects.
Psychological trauma includes all situations of psychological stress, such as
What exactly are mechanical traumas?
Mechanical trauma can occur in a wide variety of ways. Most often, it results from the use of weapons or sharp objects, but it can also be caused by bare hands.
Stab or cut wounds, in particular, can lead to severe bleeding when sharp objects sever major arteries.
Gunshot wounds can also lead to very serious consequences and become life-threatening. The danger of gunshot wounds is that once the bullet enters the body, it continues to travel and can cause massive soft-tissue damage. This tissue damage is often significantly larger and more severe than the usually small entry wound would suggest.
Blunt trauma results from the application of force without breaking the skin. This can occur, for example, from blows with a fist or hard objects, but also from joint dislocations. Blunt injuries can be very severe, yet they are often much more difficult to diagnose than penetrating injuries. This is because penetrating injuries are visible to the naked eye, whereas with blunt trauma, most of the damage occurs internally.
So-called high-velocity injuries—which are injuries caused by the impact of very high kinetic energy—also fall under the category of mechanical injuries. They occur whenever the body is moving at high speed and is abruptly brought to a stop. Typical examples of high-velocity trauma include car and traffic accidents as well as sports accidents, such as skiing or bicycle racing.
Finally, bite wounds also fall under the category of mechanical injuries; they are most commonly caused by animal bites. However, human bites are not uncommon and are often much more difficult to treat. This is because bite injuries caused by humans carry a significantly higher risk of infection.
What is meant by physical trauma?
Physical trauma refers to all injuries and their consequences resulting from extreme and pathological environmental influences. These include, among others
- Burns: These result from flames, fire, hot water, and also sunlight
- Cold trauma: Prolonged exposure to cold ambient temperatures, ice, or cold objects can lead to severe cold damage to the skin, as well as hypothermia of the entire body, potentially resulting in cardiac arrest
- Radiation damage: This primarily refers to damage caused by radioactive radiation, but sunlight and ultraviolet radiation can also lead to radiation damage
- Noise-induced injuries: These are also referred to as acoustic trauma and can result, for example, from an explosion. People who are exposed to high levels of noise in the workplace must wear appropriate hearing protection to safeguard their hearing
- Pressure injuries: These are known as barotrauma and can result from damage to the body or organs due to a change in ambient pressure. Typical examples of pressure injuries include sports injuries sustained during deep-sea diving or injuries sustained in aviation sports.
How do chemical injuries occur?
Chemical trauma refers to injuries to the body caused by exposure to toxic substances. These substances can have a harmful effect on the body in liquid, solid, or gaseous form. This can occur externally through the skin’s surface or internally through the mucous membranes and the bloodstream.
Chemical trauma includes, in particular,
- Poisoning: In this case, the toxins affect the body’s internal systems. They are ingested through the mouth, nose, or, rarely, the rectum, and enter the bloodstream via absorption in the intestines or lungs. From there, they are distributed throughout the body, leading to symptoms of poisoning in various organs. Poisoning typically results from medications, food, or beverages. It also frequently occurs due to an overdose of a medication that is generally harmless or even beneficial to health but becomes toxic only when taken in excessive amounts.
- Chemical burns: Chemical burns are characterized by damaging effects on the skin and mucous membranes, which are caused in particular by acids or alkalis. The larger the area of skin or mucous membrane affected, the more severe the impact on the entire body. If large areas of skin or mucous membrane are affected, life-threatening conditions can arise.
What are the causes of psychological trauma?
The causes of psychological trauma can be very diverse, which is why only a few examples are listed below:
- Loss of loved ones
- Jealousy
- Stress
- War and persecution
- Sexual abuse
- Childhood neglect
- Sudden Infant Death Syndrome
- Divorce/Separation
- Bullying
- Anxieties
- A life-threatening illness
- Natural disasters
- Unemployment
Trauma surgeons and emergency physicians are responsible for treating all physical consequences of trauma. Trauma surgery and emergency medicine are broad fields, and trauma physicians must be qualified in many areas. These include, first and foremost,
- first aid at the scene of the accident
- measures for treating shock, and
- follow-up surgical/orthopedic treatment in the hospital

One of the most important tasks in trauma surgery is the treatment of injuries to the musculoskeletal system. These include, for example, bone fractures or muscle and tendon injuries.
The boundaries between the fields of trauma surgery and orthopedics are fluid. For this reason, these specialty training programs were merged in Germany in 2005 (“Specialist in Orthopedics and Trauma Surgery”).
The primary goal of traumatology is to avert an acute threat to life and to manage any potential complications. Afterward, the patient is usually initially cared for in the intensive care unit.
Patients with multiple trauma must be cared for in the hospital by a well-trained and experienced team of specialists. This team includes, for example, the following specialists:
- Trauma Surgery: treats all bone and joint injuries
- Emergency medicine: responsible for initial treatment at the scene of the accident and in the emergency department
- Anesthesiology and Critical Care Medicine: treat all severe cases of shock and organ injuries
- Visceral surgery: responsible for surgeries involving injuries to abdominal organs, such as the intestines or liver
- Vascular Surgery: this specialty covers all injuries to blood vessels, including arteries and veins
- Neurology / Neurosurgery: for injuries to the head and brain
Such injuries often affect a wide variety of body regions and organ systems. Therefore, such a team consists of physicians from various specialties; the list above could be extended indefinitely.
Depending on the severity of the trauma, rehabilitation measures are necessary (often lasting months or years). These are carried out by physical and occupational therapists.
Patients who have suffered psychological trauma receive psychotherapeutic treatment within the field of psychotraumatology. Specialists in psychiatry are responsible for this. Depending on the type and severity of the trauma, various trauma therapies are available.
The various therapeutic methods aim to:
- help those affected find peace,
- analyze the psychological problems, and
- find an appropriate form of therapy.
This includes, for example, behavioral therapy. After therapy, the patient should feel able to control the symptoms of trauma, limit them, or resolve them.
