NURS 3664 Lecture Notes - Lecture 2: Muscle Weakness, Crepitus, Ossification
Document Summary
Sprain - injury to tendons/ligaments around a joint. Strain - excessive stretching of a muscle and fascial sheath. Dislocation complete separation of articular surfaces. Subluxation partial displacement from the joint. Disruption or break in continuity of the structure of bone. Fractures are described and classified according to. Anatomic location of fracture on involved bone. Displaced full break of bone, completely separated. Interarticular in joint itself, bone breaking at joint, harder to heal. Piece of periosteum is intact across fracture. Not at risk for dislodging pieces of bone and bleeding. Interrupting tissue, risk for bleeding, more difficult to treat. Mechanism of injury associated with numerous signs and symptoms. Inability to bear weight on or use affected part. Fracture may not be accompanied by obvious bone deformity. May convert a closed fracture to open from bony fragments. Bone goes through a remarkable reparative process of self-healing: fracture hematoma, granulation tissue, callus formation. Beginning of bone formation: ossification, consolidation, remodeling.
