ECE4084 Lecture Notes - Lecture 4: Pathologic Fracture, Osteosarcoma, Head Of Radius
Document Summary
Classification: causes, presence of a communicating wound, extent of damage, direction type and location, displacement. Indirect trauma: pull of a muscle (avulsion, diseased bone (pathologic, neoplasia, nutritional, repeated stress (fatigue) (racing animals) Presence of a communicating wound: closed, open, inside to out, outside to in, tend to only occur in young animals, in long bones, convex side tends to break but the concave side stays intact, fissure. Direction type and location: transverse, oblique, butterfly or wedge fragment, comminuted. Spiral: has two or more fracture lines that meet at a common point, multiple or segmental. Impacted: compression, usually metaphyseal, avulsion, sites of muscle, tendon or ligament attachment, physeal, separate grading scheme. Location: proximal, middle, distal, metaphyseal, diaphyseal, condylar, articular. Closed, highly comminuted, midshaft right femur, caudal displacement: describe the fracture (tibia) closed, pathologic fracture, transverse, distal left tibia, slight cranial displacement. + soft tissue swelling likely has osteosarcoma.
