A degloving injury is an advanced or painful wound where skin and often subcutaneous tissue become dislodged from the underlying structure. Such an injury occurs due to a collision such as a car crash, a fall, or at work. Not only are they visible injuries but they cause extreme pain and hemorrhaging while having a great possibility of extended damage.
These injuries can vary from mild to life-threatening depending on how much tissue is damaged, as well as the area concerned. The degree of injury often depends on the kind and force of the occurrence, as well as on the general condition of the victim and immediate medical help. This tutorial explains what a degloving injury is, how it occurs, and how it can be treated.
Types of Degloving Injuries
These injuries can be divided into several types based on the severity, area, and depth of the tissue involvement.
1. Skin Degloving
Skin degloving means the separation of skin from the underlying tissue; hence, it can expose big, raw areas of exposed flesh. It is the most common form of degloving injury wherein blunt force or shearing motion leads to the tearing of skin from the body, with the deeper layers of tissues being preserved.
Symptoms: Hanging skin appears with an exposed underlying layer of fat or muscle due to the open wounds, there is a lot of pain, bleeding, and swelling.
2. Tissue or Muscle Degloving
More extensive degloving can affect muscles and other deep tissues in addition to the skin. This can lead to more severe effects on function and appearance, depending on which muscle groups are affected.
Symptoms: Excessive bleeding, loss of function in the involved area, and deeper wounds that may need surgery for their closure.
3. Bony Degloving
This is the most extreme form of degloving injury, where the skin and deeper tissues are torn off from the underlying bone. Most bony degloving injuries occur in high-impact accidents, such as car crashes or industrial accidents. It can lead to permanent disability or even amputation if not treated appropriately.
Symptoms: Bone exposure is often associated with significant pain, severe bleeding, and complicated soft tissue loss, including complex fractures.

Causes of Degloving Injuries
These injuries mostly result from extreme external force or trauma.
1. Motor Vehicle Accidents
This is one of the most significant causes of degloving injury, especially bony degloving. Motor vehicle accidents, particularly high-speed impacts, tend to catapult or drag the body against surfaces, thus causing violent tearing of the skin along with its deeper structures.
2. Industrial Accidents
These injuries are also caused by workplace accidents, especially those involving heavy machinery. Construction, manufacturing, and agricultural settings are more prone to such injuries if safety protocols are not followed.
3. Sports Injuries
Degloving injuries can be caused by contact sports, high-speed sports, or falls during physical activities. The risk is higher in athletes who experience falls, collisions, or blunt force trauma.
4. Animal Attacks
Animal bites or attacks, especially from dogs or large animals, can cause degloving injuries, particularly if the skin is torn away by the animal’s bite force.
5. Trauma from Machinery or Equipment
Machinery and equipment that have rotating parts or cutting parts are predisposed to causing degloving injuries when any limb or body part becomes lodged in them. The injury is frequently witnessed in factories, especially where workers don’t wear adequate protective gear.

Symptoms of Degloving
The symptoms of a degloving injury can vary depending on the degree and severity of the trauma.
- Extreme pain in the injured area
- Tissue or muscle exposed, with loose hanging skin
- Excessive bleeding (more so in cases of deeper degloving)
- Swelling and bruising
- Loss of function or an inability to move the affected area
- Shock, especially in the case of larger or more severe injuries, where rapid heartbeat, dizziness, or even fainting can occur
Diagnosis of Degloving Injuries
Immediately, a person ought to seek medical attention if they sustain a traumatic injury that potentially leads to a degloving injury. A qualified healthcare provider will therefore conduct a physical examination that may involve the use of imaging tests such as X-rays, CT scans, or MRIs to determine the areas of tissue and bone involvement. In this way, the specific treatment will be determined.
Treatment for Degloving
Treatment for degloving injuries is largely dependent on the level of injury, the area, and the extent of tissue damage. Prompt and appropriate intervention helps ensure better outcomes and limits complications such as infection or permanent disability.
1. Primary First Aid
- Control the bleeding: Use a clean cloth or gauze to stop bleeding.
- Wound care: Cover the wounded area with a sterile gauze or cloth to keep contamination out.
- Immobilise affected region: Immobilize the area when feasible.
2. Cleaning and Debridement of Wound
For severe injuries, cleaning the wound and removing dead tissue is important to prevent infections and ensure healing. This must be done in the operating room, and the healthcare provider may need to do this procedure for the patient.
3. Surgical Correction
- Skin grafting: If the damage to the skin is more severe or it is entirely lost, then a graft of skin may be used to cover the exposed tissues. This is done by obtaining skin from a donor site on the patient’s body and transplanting it onto the injured area.
- Reconstructive Surgery: If muscles or bones are involved, then reconstructive surgery might be needed to restore function and appearance. This could include a muscle flap or bone fixation depending on the injury.
4. Infection Prevention
- Antibiotics are usually given in advance to prevent infections, particularly when the tissue is exposed to large areas.
- Tetanus vaccination is also likely to be administered, depending on the object and nature that causes injury.
5. Pain Management and Rehabilitation
Effective management of pain and rehabilitation (physical therapy) after the injury healed is essential for improving mobility and function. Rehabilitation helps patients regain strength, prevent contractures, and reduce long-term complications.

Complications of Degloving Injuries
Degloving injuries have several possible complications, including:
- Infection: An open wound will always be prone to infection by bacteria. If not addressed properly, this may result in sepsis.
- Nerve Damage: Severe degloving injuries may lead to damage to nerves, which could result in loss of sensation or motor function.
- Loss of Function: The degree and site of a degloving injury may affect the function of the limb or body part involved, sometimes permanently.
- Amputation: At times, the injury may be so severe that it necessitates amputation.
Prevention of Degloving Injuries
Though it is almost impossible to prevent the causation of traumatic accidents, one can reduce the degree of degloving injury to a certain extent through the following steps:
- Safety Apparel: Wearing protective gear including gloves, helmets, and adding while working in industrial or dangerous setups can avoid serious damage to the body.
- Vehicular Safety: Follow safety rules and regulations of traffic, seatbelt wearing, and avoiding distraction from vehicular operations to limit accidental injuries.
- Workplace Safety: Involves the assurance that all safety measures are taken in industries with heavy machinery by observing the lockout-tagout procedures, wearing protective clothing, etc.
- Sports Safety: By using the appropriate equipment and safety measures, injuries could be reduced greatly in the course of sports.
Sum-up
Degloving injuries are traumatic injuries that need timely and complicated treatment for the best possible outcome and the least amount of long-term complications. Knowledge about their etiology, mechanism, types, and ways of treating them may prevent the onset of these injuries and speed up appropriate care in their management. Degloving injuries call for prompt medical treatment to reduce long-term health impacts and ensure good recovery outcomes when such injuries occur in you or anyone around.
