NURS 3664 Lecture Notes - Lecture 2: Epiphyseal Plate, Humerus Fracture, Human Musculoskeletal System
Document Summary
Aims: describe the structure and functions of the musculoskeletal system, differentiate among the etiology, pathophysiology, clinical manifestations, and care of sprains, strains, dislocations, subluxations and fractures. Structures and functions of musculoskeletal system: muscle, connective tissue, bones, cartilage, ligaments and tendons, fascia and bursae, bone functions, support, protection, voluntary movement, blood cell production, mineral storage. Cellular bone formation: bone not static, dynamic state, osteoblasts, osteocysts, osteoclasts. Joints are classified by the degree of movement that they allow. Soft tissue injuries: sprain - injury to tendons/ligaments around a joint, strain - excessive stretching of a muscle and fascial sheath, symptoms, pain, edema, swelling, tenderness, nsg dx, acute pain. I - ice: r rest, c compression (ace wraps, splints, e - elevation, dislocation complete separation of articular surfaces, subluxation partial displacement from the joint. A patient has a severely sprained ankle from a sports injury. Immobilize extremity if fracture is suspected: unnecessary movement.
