Soft tissue injury in closed fractures

GradeFeatures
Grade 0Injury from indirect forces with negligible soft tissue injury
Grade 1Superficial abrasion and contusion of soft tissue overlying fractures
Grade 2Significant muscle contusion, with possible deep, contaminated skin abrasion associated with moderate to severe energy mechanism and skeletal injury
Grade 3Extensive crushing of soft tissue with subcutaneous degloving or avulsion, and arterial disruption or established compartment syndrome
