skin avulsion
Introduction
Introduction Skin avulsion is caused by the external force generated by the wheel or the belt, and the skin and subcutaneous tissue are forcibly exfoliated from the deep or shallow surface of the deep fascia, accompanied by varying degrees of soft tissue crushing damage.
Cause
Cause
Hand and upper limb skin avulsion injury as an unfortunate consequence of trauma such as work injury and traffic accident, has a gradually increasing trend, which is consistent with the economic development of the society. The anatomical level of skin avulsion, the back of the finger and the back of the hand are loose. Above the deep fascia, the palm is often avulsed from the shallow side of the palmar membrane. Treatment should be carefully and thoroughly debrided early. Skin grafts or flap grafts are performed as appropriate.
The large scalp avulsion from the cap-like aponeurosis is called scalp avulsion, which is caused by the hair being entangled by the machine, and the high-speed blunt object tangential strike can also be caused. The patient has a large amount of bleeding, often accompanied by shock. The avulsion is often between the cap-like diaphragm and the periosteum of the skull, and sometimes the entire scalp is even avulsed together with the frontal muscle, diaphragm or periosteum. This type of injury is characterized by more blood loss and infection. If the treatment is not timely, it may endanger life or cause necrosis of the skull.

Avulsion injury - symptoms and signs
Head avulsion injury symptoms:
1. The scalp is avulsed under the cap-like aponeurosis. Sometimes the entire scalp and even the frontal muscle, diaphragm, and periosteum are avulsed together, and the skull is exposed.
2, the amount of bleeding is large, often accompanied by shock.
3, the skull exposed for a long time can be complicated by skull infection or necrosis.
Clinical manifestations of hand avulsion injury:
1. The skin of the hands and upper limbs is avulsed.
2, muscles, tendons, nerves, blood vessels, bones and joints can be damaged; multiple injuries throughout the body.
3, shock can appear.
Avulsion injury - diagnosis basis
Diagnosis of head avulsion injury:
1. Hair is caught in the machine and other traumatic history.
2. The scalp is avulsed from under the aponeurotic or subperiosteal, often in a wide range, with more bleeding, sometimes combined with shock, and in a few cases can be avulsed by subcutaneous layers.
3. The scalp is full of defects, the skull is exposed, and the skull infection or necrosis can be complicated.
Diagnosis of hand avulsion injury:
1. History of trauma.
2. The skin of the hands and upper limbs is avulsed.
3. Multiple injuries and shocks can occur throughout the body.
4. There may be muscle, tendon, nerve, blood vessel, bone and joint damage.
Diagnosis
Differential diagnosis
Skin abrasion: abrasion is the skin's skin abrasions. If the scratched area is light, just apply red syrup; if the wound is dirty or oozing, apply saline to remove the red syrup or purple syrup.
