Musculoskeletal DisordersReview of Bone physiology this is a picture of normal bone, with osteoblasts rebuilding injured or old bone, faster than osteoclasts can break it down

Healthy bone

17

Musculoskeletal DisordersThis is one osteoclast dissolving boneAs part of the normal healing process

18

MusculoSkeletal Disorders

Healthy bone provides structure and support for the human body.The marrow makes stem cells which produce our red and white cells when theymature.

19

Osteoporosis

Musculoskeletal Disorders----Osteoporosis

Osteoporosis number one cause of fractures in the elderly, >1.5 million per yearPrimary Osteoporosis is caused by osteopenia or thinning of the bone. This occurs when osteoclastic bone loss is faster than osteoblastic (bone building) activity.This is measured by BMD (bone mineral density)Osteopenia = T-score of less than- 1.0Treatment starts here, new guidelines 2008Osteoporosis = T-score of > -2.5

21

Musculoskeletal Disorders- -----OsteoporosisSecondary OsteoporosisCaused by other disease mechanisms, or treatments, i.e. long term corticosteroids, methamphetamine or alcohol abuse, or prolonged immobility can occur within 12 weeksTreatments are the same for both types and osteoclastic activity is the same

26

Musculoskeletal diseasesOsteoporosisDiagnostics:DEXA Scan Screening annually of post-menopausal women DEXA Screening for hypothyroid and hyperthyroid patients Qualitative US not used muchBone Scan is used for differential diagnostics, i.e. to rule out bone cancerLabs for Calcium, Magnesium, Phosphorus levelsUrine for pyridinium levels

27

DXA ScanThis is a typical bone densitometry study. A low dose x-ray is performed of the lumbar spine, hip (shown here) or wrist. From the resulting image /measurement, calculations can be made to determine the density of the patient's bone (T-score) and compare it to the reference standard of a healthy thirty-year-old of the same sex and ethnicity to determine future risk of fracture.

Musculoskeletal diseasesOsteoporosis Treatments and Nursing Interventions Educate Side effects of meds Calcium supplementation new evidence is 1700 mg of calcium per day, or more for post-menopausal women not on hormone therapy. May use TUMS if stomach is upset with supplementsExercisesFall prevention and safetyBiphosphonates i.e. Fosamax, Actonel, Boniva have to be taken 1 hour before any other foods or vitamins, with only water to be absorbed.Vitamin D therapy not usually needed in the sunny desert, found in dairy and green leefy vegetables

29

Fractures

Musculoskeletal DisordersFracture treatmentNursing primary concern is to assess and prevent neuro-vascular dysfunction. Neuro / circulation checks should be done of the affected limb every 15 minutes x 4, then every 30 minutes x2, then every hour. ( The book says every hour, but that is really too long, and your patient could go into shock)Immobilize the limbControl the painAssess for shock

31

Risk for Peripheral Neurovascular deficitOther fracture interventions (with casting or immobilization/traction).Monitor for numbness, tingling, hyperesthesia, hypoesthesiaMonitor for DVTs check pulses and colorInstruct the client to examine the skin daily for any breakdown or alterations, call MD if oozing or redness occurInstruct client to avoid crossing their legsInstruct patient to completely abstain from tobacco Remove home safety hazards in the homeInstruct patient not to scratch underneath the cast or around the pins/tractionGive patient anticoagulants and analgesics if orderedInstruct patient to take vitamins, adequate amoaunts of magnesium, vitamin C, etcfor healing.

Musculoskeletal DisordersFractures- Pathological fracturesoccur when abnormal force is applied, or the bone is already weakened (osteoporosis, cancers, sarcomas, benign bone cysts, etc.). The type of fracture depends on the type of loading force and stress applied to the bone. See below.Closed - Greenstick -Spiral - Open (compound)

Musculoskeletal Disorders Fractures- Complications of fractures include:Fat emboli syndrome/CVA/Stroke Hematoma (leakage from the bone marrow usually), which can also be a hemmorhageCallus formation DVT- thromboembolismInfection to OsteomyelitisIschemic necrosisFracture blistersDelayed union, nonunion, and malunionOsteoblastic proliferation..
