Final answer:
A degloving injury is the traumatic removal of skin and subcutaneous tissue that separates tissue planes from their blood supply. Skin grafts may be required for treatment, and several steps like coagulation, scab formation, and angiogenesis play a role in the healing process.
Step-by-step explanation:
The traumatic removal of skin and subcutaneous (SQ) tissue that separates tissue planes from their blood supply, especially from a limb, is known as a degloving injury. This type of injury often requires intervention such as skin grafts to cover the area where the skin and tissues have been removed because they cannot be sufficiently closed with sutures or staples. During the tissue repair phase post-injury, processes such as coagulation, scab formation, and angiogenesis, among others, aid in wound healing. For significant wounds, secondary union might be necessary, involving wound contraction to pull the edges together and the possibility of using sutures to encourage proper healing and minimize scarring.
