Study Notes
Musculoskeletal Disorders
- Musculoskeletal system consists of skeletal system (bones and joints) and muscular system (involuntary and skeletal)
- Bones store calcium and phosphorus, protect vital organs, and produce blood cells through red marrow
- Muscular system issues are often related to bone problems
Osteopenia and Osteoporosis
- Osteopenia: decreased bone density, often seen in older patients
- Osteoporosis: severe osteopenia, increasing risk of fractures, especially in older patients
- Identify people with osteoporosis and start interventions to prevent complications
Osteoporosis Terminology
- Osteomalacia: bone softening, often seen in adults with vitamin D deficiency
- Bone remodeling: ongoing process of bone formation and resorption
- Osteoblasts: build bone, osteoclasts: consume bone
- Peak bone mass: reached at 30 years of age
Types of Osteoporosis
- Primary osteoporosis: no direct cause, but many risk factors
- Secondary osteoporosis: caused by other conditions or medications
- Regional osteoporosis: localized to one area, such as astronauts' legs due to lack of gravity
Risk Factors
- Age: older patients are at higher risk
- Family history: especially if mother had osteoporosis
- Nutrition: lack of calcium and vitamin D
- Exercise/immobility: not enough weight-bearing activity
- Smoking/alcohol: increase risk of osteoporosis
- Hormone deficiency: menopause, radical hysterectomy
- Weight: being underweight, taking diuretics and steroids
Signs and Symptoms
- Bone pain, loss of height, neck/back pain, stooped posture
- ADLs are affected
Diagnostic Testing
- Labs: calcium and vitamin D levels
- Imaging: dual x-ray absorptiometry (DXA) to measure bone density
Prevention and Treatment
- Vitamin D and calcium supplements
- Exercise: weight-bearing activities, 30 minutes, 3-4 times a week
- Limit alcohol and tobacco
- Drug therapy: bisphosphonates, estrogen agonist/antagonists for postmenopausal women or men over 50 with low bone density
Medications
Calcium
- Used to treat mild hypocalcemia, supplement dietary calcium, and prevent osteoporosis
- Administer with vitamin D, take with water or after a meal
- Monitor calcium, vitamin D, and phosphorus levels
- Adverse effects: kidney stones, hypercalcemia, hypophosphatemia
Vitamin D
- Used to treat osteomalacia, prevent osteoporosis
- Administer with calcium, evaluate calcium, vitamin D, and phosphorus levels
- Adverse effects: hypercalcemia, hypophosphatemia
- Monitor for improvement in osteomalacia, stabilization of osteoporosis, and no new fractures
Bisphosphonates
- Used to treat osteoporosis
- Report dysphagia, dyspepsia, pain, or swelling in the mouth
- Adverse effects: osteonecrosis of the jaw, esophagitis
- Monitor for stabilization of osteoporosis and no new fractures
Raloxifene (Evista)
- Used to prevent and treat postmenopausal osteoporosis
- Monitor for symptoms of venous thromboembolism
- Adverse effects: deep vein thrombosis, pulmonary embolism### Thrombotic Stroke
- Estrogen can help with bone density and prevent osteoporosis in postmenopausal patients, but its adverse effects include stroke, clotting (DVT), and PE.
- Clotting is a significant concern with this medication.
- Patients with a history of stroke are usually prohibited from taking birth control.
Osteomyelitis
- Osteomyelitis is an infection in the bone tissue caused by bacteria, viruses, parasites, or fungi.
- It can be bacterial, viral, or fungal, and is typically seen in diabetics due to poor blood flow and PAD.
- Neuropathy and PAD can influence this condition.
- IV drug abusers are also at risk due to dirty tools and infected blood.
- Exogenous osteomyelitis occurs when an external source (e.g., trauma) introduces bacteria directly to the bone.
- Endogenous osteomyelitis occurs when an internal source (e.g., sepsis) settles in the bone.
- Gangrene can lead to osteomyelitis due to skin infection leading to deeper infection.
Osteomyelitis Clinical Manifestation
- Acute phase: fever, chills, swelling, tenderness, erythema, heat, and pain.
- Chronic phase: may not feel pain, but could have drainage, pain depending on circulation, or bone surgery.
Risk Factors: Osteomyelitis
- Immunosuppressed individuals (e.g., HIV, elderly, or immunosuppressive meds).
- Malnourishment (insufficient nutrients for healing).
- Chronic illnesses (e.g., diabetes).
- Medications (e.g., steroids, diuretics).
- Bloodstream infection.
- Wounds.
- Artificial joints (prone to infection).
Osteomyelitis Diagnosis
- Labs: nonspecific leukocytosis (high WBC).
- Cultures: blood, wound, or areas near the wound.
- X-ray: changes in bone structure.
- MRI: detailed diagnosis.
- Biopsy: most optimal, confirming the diagnosis.
Treatment
- Nonsurgical:
- Antibiotic therapy (used often for bacterial cases).
- Pain control (extremely painful).
- Hyperbaric Oxygen Therapy (HBO) (increases oxygen in the bone, promoting healing).
- Surgical:
- Debridement or bone excision (removing infected bone).
- Amputation (in severe cases).
Fractures
- Complete: a complete break in the bone.
- Incomplete: does not completely sever the bone, more common in kids.
- Closed: skin is still intact with the fracture.
- Open: skin is open, exposing the bone (aka compound fracture).
Types of Fractures
- Pathologic Fracture (Spontaneous fracture):
- Underlying disease causes weak bones (e.g., osteoporosis, osteomalacia, bone cancer).
- Stress Fracture (Fatigue fracture):
- Results from excessive stress or strain on the bone (e.g., repetitive motions).
Fracture Complications
- Acute:
- Venous Thromboembolism (VTE).
- Infection.
- Acute Compartment Syndrome (ACS).
- Fat Embolism Syndrome (FES).
- Chronic:
- Delayed bone healing.
- Chronic pain.
Acute Compartment Syndrome (ACS)
- A circulatory concern that can lead to loss of limb if not treated.
- Compression on arteries and nerves can cause paresthesia, pulse changes, and paralysis.
- 6 P's of ACS: pain, paresthesia, pulse, pallor, pressure, and paralysis.
Medical Management ACS
- Contact surgeon immediately.
- Keep the extremity at heart level.
- Remove dressings or casts.
- Prepare for surgery (fasciotomy).### Fat Embolism Syndrome (FES)
- Fat enters bloodstream, especially in long bone fractures
- Occurs 12-48 hours post-injury
- Clinical manifestations:
- Respiratory changes
- Neurological changes
- Skin: petechial rash
- Fatty bone marrow enters bloodstream, causing symptoms like breathlessness, hypoxia, and neurological changes
- Can lead to seizures, confusion, and agitation if fat enters arterial circulation and reaches the brain
- Skin manifestations: petechial rash (pinpoint spots) due to increased pressure in capillary beds causing pinpoint bleeding
Management of FES
- Prevention:
- Early fracture immobilization
- Careful repositioning of patients
- Special surgical techniques to decrease the chance of fat embolism
- Recognize and report it right away
- Supportive care:
- Respiratory support: oxygen, ventilator
- Cardiovascular support: fluids, DVT prophylaxis, vital signs monitoring, meds to regulate heart rhythm
- Corticosteroids for inflammation (not shown to reduce mortality, but used in practice to prevent systemic response)
Management of Fractures
- ABC's (Airway, Breathing, Circulation)
- Neurovascular check (6 P's)
- Pain management
- Reduction and immobilization
- Elevation to prevent inflammation and reduce edema and ACS
Immobilization of Fractures
- External immobilization: casts, splints, boots
- Internal immobilization: screws, plates, rods (surgical management)
Cast Care
- Nothing under the cast, even if it gets itchy
- Keep it clean and dry
- Educate patient about 6 P's (neurovascular issues)
Traction
- Way to reduce bones
- Weight keeps traction
- Assess for pain, neurovascular status, and pressure points
External Fixation
- Advantages: alignment, early mobilization, wound care
- Disadvantages: increased infection, osteomyelitis, altered body image
- Pins go into skin and bone, requiring careful pin care
Open Reduction Internal Fixation (ORIF)
