DEGLOVING INJURY

SCF ENCYCLOPEDIA ENTRY

DEGLOVING INJURY

Definition

DEGLOVING INJURY (DI) is a severe traumatic soft-tissue avulsion injury characterized by the circumferential or partial separation of skin, subcutaneous tissue, fascia, and associated soft tissue structures from their underlying musculoskeletal attachments. The injury results in disruption of perforating blood vessels, lymphatic channels, sensory nerves, and connective tissue support systems, producing extensive tissue devascularization, necrosis risk, contamination, functional impairment, and reconstructive challenges.

Degloving injuries occur when powerful shearing, rotational, traction, or crushing forces separate superficial tissue layers from deeper structures. These injuries commonly affect the extremities, scalp, trunk, pelvis, genitalia, and foot and are frequently associated with high-energy trauma, fractures, neurovascular injuries, crush syndrome, compartment syndrome, and complex tissue loss.

Within the Synergistic Compatibility Framework (SCF), DEGLOVING INJURY is classified as a Soft Tissue Envelope Avulsion and Neurovascular Interface Disruption Syndrome, characterized by traumatic separation of integumentary and subcutaneous structures from underlying anatomical frameworks, resulting in vascular compromise, tissue viability failure, regenerative dysfunction, and biomechanical instability.

Encyclopedia Summary

DEGLOVING INJURY (DI) is a Soft Tissue Envelope Avulsion and Neurovascular Interface Disruption Syndrome characterized by traumatic separation of skin, subcutaneous tissue, fascia, and associated soft tissue structures from underlying anatomical frameworks. Within the SCF framework, Degloving Injury represents a severe form of soft tissue trauma involving disruption of vascular, lymphatic, neurologic, regenerative, and biomechanical networks. The syndrome may progress to tissue necrosis, complex tissue loss, infection, limb-threatening compromise, and systemic complications if not rapidly managed. Effective management focuses on tissue preservation, restoration of perfusion, infection prevention, reconstruction of soft tissue coverage, preservation of neurologic and functional integrity, and comprehensive rehabilitation aimed at maximizing tissue salvage, limb function, independence, and long-term quality of life.
