Degloving injuries are severe and often life-threatening traumas that require immediate medical attention. These injuries occur when the top layers of skin and tissue are torn away from the underlying muscle, connective tissue, or bone. Understanding the types and causes of degloving injuries is crucial for prompt and effective treatment. This comprehensive guide will explore the different types of degloving injuries, their causes, and the importance of immediate medical intervention.
Understanding Degloving Injuries
Degloving injuries are characterized by the separation of skin and underlying soft tissue from the deeper structures of the body. This type of injury is often referred to as avulsion and can be extremely serious, requiring emergency treatment. The term “degloving” comes from the appearance of the injury, which resembles the removal of a glove from a hand, where the skin is peeled back, exposing the underlying tissues.
Types of Degloving Injuries
Degloving injuries can be categorized into two main types: open and closed.
- Open Degloving Injuries:
- Description: Open degloving injuries are more obvious and graphic. They occur when a section of skin and tissue is ripped away, leaving muscles, tendons, connective tissue, and sometimes bones exposed. The skin may be completely removed from the body or partially attached and hanging as a flap.
- Common Locations: These injuries are most often seen on the legs, torso, and scalp.
- Causes: Open degloving injuries typically result from high-energy traumas such as motor vehicle accidents, industrial accidents, or severe falls. The force involved in these incidents can cause the skin to tear away from the underlying tissues, leading to significant blood loss and exposure of deeper structures 910.
- Closed Degloving Injuries:
- Description: Closed degloving injuries are internal wounds that occur when the skin and fat are ripped apart from deep layers of muscle and connective tissue. These injuries are less obvious and graphic, making them harder to diagnose. The top layers of skin usually show no major signs of injury other than maybe some bruising.
- Common Locations: Closed degloving injuries often occur at the top of the hip bone but can also affect the torso, buttocks, lower spine, shoulder blades, and knees.
- Causes: These injuries are usually associated with high-energy trauma and can be devastating. They occur when a tangential shearing force causes the superficial fascia to separate from the deep fascia, severing the perforating vessels and creating a potential space for fluid collection. This type of injury is often referred to as a Morel-Lavallée lesion when it occurs in the pelvic or thigh region 1112.
Causes of Degloving Injuries
Degloving injuries can result from various types of accidents and traumas. Understanding the common causes can help in preventing such injuries and ensuring prompt treatment.
High-Energy Traumas
High-energy traumas are the most common causes of degloving injuries. These include:
- Motor Vehicle Accidents:
- Mechanism: The force involved in motor vehicle accidents can cause the skin to tear away from the underlying tissues. This is often seen in pedestrian accidents, motorcycle accidents, and high-speed collisions.
- Impact: The impact of such accidents can lead to both open and closed degloving injuries, depending on the nature of the collision and the areas of the body affected 13.
- Industrial Accidents:
- Mechanism: Industrial accidents involving heavy machinery, conveyor belts, and roller machines can cause severe degloving injuries. Workers can get caught in the machinery, leading to the skin being pulled away from the underlying tissues.
- Impact: These accidents often result in open degloving injuries, exposing muscles, tendons, and bones. Immediate medical attention is crucial to prevent further damage and infection 13.
- Falls from Heights:
- Mechanism: Falls from significant heights can cause degloving injuries, especially if the individual lands on a hard surface or an object that causes a shearing force.
- Impact: The force of the fall can lead to both open and closed degloving injuries, depending on the point of impact and the nature of the fall 11.
Sports and Recreational Activities
Sports and recreational activities can also lead to degloving injuries, particularly in high-impact sports:
- Contact Sports:
- Mechanism: Sports like football, rugby, and hockey involve high-impact collisions that can cause degloving injuries. The force of impact can lead to the skin being torn away from the underlying tissues.
- Impact: These injuries are often seen in the extremities, such as the legs and arms, and can be both open and closed degloving injuries 14.
- Extreme Sports:
- Mechanism: Extreme sports like skiing, snowboarding, and mountain biking involve high speeds and the risk of falls, which can lead to degloving injuries.
- Impact: The nature of these sports increases the risk of high-energy traumas, leading to severe degloving injuries that require immediate medical attention 10.
Everyday Accidents
Everyday accidents can also result in degloving injuries, although they are less common:
- Domestic Accidents:
- Mechanism: Accidents involving power tools, kitchen appliances, and other household items can cause degloving injuries. For example, getting a hand caught in a blender or a foot trapped in a lawnmower can lead to severe injuries.
- Impact: These accidents often result in open degloving injuries, exposing the underlying tissues and requiring immediate medical intervention 10.
- Animal-Related Injuries:
- Mechanism: Animal bites and attacks can cause degloving injuries, especially if the animal’s teeth or claws penetrate deeply into the skin and underlying tissues.
- Impact: These injuries can be both open and closed, depending on the nature of the attack and the areas of the body affected 10.
Diagnosis and Treatment
The diagnosis and treatment of degloving injuries depend on the type and severity of the injury. Prompt and accurate diagnosis is crucial for effective treatment and recovery.
Diagnosis
- Open Degloving Injuries:
- Visual Assessment: Open degloving injuries are easier to diagnose as the muscle and bone will be exposed where the skin has been ripped away. The extent of the injury can be visually assessed, and the necessary steps for treatment can be taken immediately.
- Imaging: X-rays, CT scans, and MRIs may be used to assess the extent of the injury and any associated fractures or damage to underlying structures 15.
- Closed Degloving Injuries:
- Clinical Examination: Closed degloving injuries are harder to diagnose as they are internal wounds. A thorough clinical examination, including assessing skin color, temperature, and pressure reaction, is necessary.
- Imaging: MRI is the diagnostic imaging of choice for closed degloving injuries. It can help identify the extent of the injury, the size and shape of the fluid collection, and the viability of the affected tissues 11.
Treatment
The treatment options for degloving injuries depend on the severity and location of the injury, as well as the presence of any associated fractures or damage to underlying structures.
- Open Degloving Injuries:
- Immediate Care: The first step in treating open degloving injuries is to control bleeding and prevent infection. The wound is cleaned, and any dead tissue is removed.
- Surgical Intervention: Depending on the extent of the injury, surgical intervention may be required. This can include debridement, skin grafts, or flap coverage to restore the integrity of the skin and underlying tissues. In some cases, replantation and revascularization may be necessary to reattach and restore blood flow to the affected area 12.
- Closed Degloving Injuries:
- Conservative Management: Mild closed degloving injuries may be managed with compression bandages to control edema and promote wound healing.
- Surgical Intervention: More severe closed degloving injuries may require surgical intervention, including fluid drainage and removal of dead tissue. In some cases, skin grafts or flap coverage may be necessary to restore the integrity of the skin and underlying tissues 10.
Complications and Long-Term Effects
Degloving injuries can have significant long-term effects and complications, depending on the severity of the injury and the effectiveness of the treatment.
- Infection:
- Risk: One of the most significant risks associated with degloving injuries is infection. The exposure of underlying tissues and the potential for dead tissue to remain in the wound can increase the risk of infection.
- Management: Prompt and thorough cleaning of the wound, removal of dead tissue, and administration of antibiotics can help prevent infection and promote healing 15.
- Scarring and Cosmetic Concerns:
- Impact: Degloving injuries can result in significant scarring and cosmetic concerns, especially in open injuries where the skin has been completely removed.
- Management: Scar modalities and cosmetic procedures may be necessary to improve the appearance of the affected area and help patients regain mobility and confidence 11.
- Functional Impairment:
- Impact: Depending on the location and severity of the injury, degloving injuries can lead to functional impairment. This can include loss of mobility, strength, and sensation in the affected area.
- Management: Physical therapy and rehabilitation can help patients regain mobility and function. In some cases, additional surgical procedures may be necessary to restore function and improve quality of life 14.
