Degloving Injury

Overview

A degloving injury is a serious form of trauma in which the top layers of skin and the tissue just beneath them are torn away from the deeper structures, such as muscle, connective tissue, or bone. The name comes from the way the skin can peel back like a glove being pulled off a hand. These injuries can be open, with skin visibly torn away, or closed, where the skin looks intact on the surface but has been separated from the tissue underneath.

Degloving injuries are medical emergencies because they can damage the blood supply to the skin and deeper tissues, leading to tissue death, heavy bleeding, and a high risk of infection. They usually require urgent surgical treatment and can need a long period of healing and rehabilitation.

Symptoms

Signs depend on whether the injury is open or closed.

• Open degloving: A large area of skin visibly torn or peeled away, exposing muscle, fat, or bone, often with significant bleeding and severe pain.
• Closed degloving: The skin may look intact but feels loose, with bruising, swelling, and a soft, fluid-filled area where the skin has separated from the tissue beneath.
• Discoloration of the skin, which may turn pale, dusky, or dark if its blood supply is damaged
• Numbness in the affected area
• Signs of shock with severe injuries, such as a fast heartbeat, dizziness, or fainting

Closed degloving can be easy to miss at first, so any large area of loose, bruised, swollen skin after a heavy impact should be checked.

Causes

Degloving injuries result from strong forces that shear the skin away from deeper layers. Common causes include:

• Road traffic accidents: Especially motorcycle and pedestrian collisions.
• Industrial and machinery accidents: Limbs caught in conveyor belts, rollers, or rotating equipment.
• Falls from height and crush injuries.
• Animal bites and sports injuries in some cases.

These high-energy forces tear the connections that hold skin to the tissue beneath, often damaging the small blood vessels that keep the skin alive.

Risk Factors

• Working with heavy machinery or moving parts
• Riding motorcycles or being a pedestrian or cyclist in traffic
• Activities with a high risk of falls or crush injuries
• Older age and conditions that weaken skin or impair healing, such as diabetes

Diagnosis

Open degloving is usually obvious on examination, but the full extent of damage, and closed degloving in particular, may need imaging. Doctors assess the wound, the blood supply to the skin, and any injury to bones or other structures.

• Physical examination: Checking the size of the injury, skin color and viability, sensation, and bleeding.
• Imaging: X-rays, ultrasound, CT, or MRI to look for underlying fractures, fluid collections, and the depth of tissue separation.

Assessing whether the detached skin still has a working blood supply is a key part of planning treatment.

Treatment

Degloving injuries require urgent care to control bleeding, prevent infection, and save as much tissue as possible. Treatment is individualized and often involves a surgical team.

• Emergency stabilization: Controlling bleeding, managing pain, and treating shock.
• Wound cleaning: Thorough cleaning and removal of dead or contaminated tissue.
• Reattachment or skin grafting: If the torn skin is still viable, it may be repositioned; if not, skin grafts or flaps from elsewhere on the body may be needed.
• Drainage: Closed degloving with fluid buildup may need drainage and compression.
• Antibiotics and tetanus protection: To reduce the risk of infection.
• Reconstructive surgery and rehabilitation: Often staged over time, with physical therapy to restore function.

Recovery can be lengthy, and the outcome depends on the size of the injury, the body part involved, and how well the blood supply is preserved.

Prevention

• Use machine guards, safe procedures, and protective equipment around moving machinery
• Wear protective gear and follow road safety practices, especially on motorcycles
• Keep loose clothing, hair, and jewelry away from rotating equipment
• Follow workplace safety training and report hazards

When to See a Doctor

A degloving injury is a medical emergency. Call emergency services or go to the nearest emergency department immediately if skin has been torn away or a large area of skin has been separated from the tissue beneath. While waiting for help:

• Apply firm pressure with a clean cloth to control bleeding
• Keep the injured area still and, if possible, raised
• Do not try to clean deep wounds or push tissue back into place yourself
• Keep any torn tissue clean and bring it with you, as it may be reused

Seek urgent care even for closed injuries if a large area of skin feels loose, bruised, and swollen after a heavy impact.
