PATH 200 Lecture Notes - Lecture 10: Sprain, Sorption, Osteoporosis
Document Summary
What are some potential risks of using a cast? may atrophy in long term, misalignment, infection, swelling in the earlier phases of fracture (may not allow proper circulation leads to tingling, numbness) opposite direction in the tissues surrounding a broken bone, to produce immobility, maintaining alignment (reduction: some risks/complications: bed sores, atrophy, blood clot. Internal fixation device (e. g. : pins, screws, plates) may be used to keep bones stabilized and aligned: the device is inserted surgically to ensure the bones remain in optimal position, allows shorter hospital stays, enables patients to return to function earlier, and reduces the incidence of nonunion and malunion, some potential risks: infection, hemorrhage, misalignment, pain, possible rejection, sometimes can be permanent/ temporary. Usually staphylococcus aureus (adheres well to bone and can hide in osteoblasts) endogenous = spread from other site of infection through blood (ear, skin, sinus, teeth) hematogenous spread common in children exogenous = from outside (open wound, compound fracture, bite, surgery, prosthetic joints)
