Tscherne classification
From Wikipedia, the free encyclopedia
The Tscherne classification is a system of categorization of soft tissue injuries.[1]
| Tscherne Grade | Open soft tissue injuries | Closed fractures |
|---|---|---|
| 0 | Fr. C 0 - No or minor soft-tissue injury from a simple fracture due to indirect trauma | |
| I | Fr. O 1 - Skin lacerated by bone fragment. No or minimal contusion to the skin | Fr. C 1 - Superficial contusion or abrasion to the skin |
| II | Fr. O 2 - Skin laceration with circumferential skin or soft-tissue contusion and moderate contamination | Fr. C 2 - Deep contaminated abrasions with skin or muscle contusion from direct trauma |
| III | Fr. O 3 - Extensive soft-tissue damage with major vessel or nerve injury | Fr. C 3 - Extensive skin contusion with destruction of subcutaneous tissue avulsion or muscle destruction |
| IV | Fr. O 4 - Subtotal and total amputations with separation of all important anatomical structures |
Reliability
The intraobserver (observations at two different times by the same person) agreement for Tscherne classification is 85%; while for inter-observer agreement is 65%.[2]
