Study Notes

Joints

Joints allow movement between bones
There are 3 main types of joints:
- Nonsynovial (Fibrous)
- Synovial (diarthrodial)
- Cartilaginous

Aging and the Musculoskeletal System

Decreased muscle cells with age
Loss of elasticity in ligaments and cartilage
Joint problems are more common as age progresses
Decreased bone density (Osteoporosis)
Osteoarthritis

Musculoskeletal System Assessment & Diagnostic Tests

Radiological Studies
- X-ray
- MRI
- Computed Tomography (CT)
- Arthrography
- Bone Mineral Density (BMD) Measurement
- Radioisotope Studies (Bone Scan)
- Arthroscopy
Blood Tests:
- Mineral Metabolism:
  - Alkaline Phosphatase
  - Calcium
- Serological Studies:
  - Uric Acid
  - Erythrocyte Sedimentation Rate (ESR)
  - C-Reactive Protein
- Muscle Enzymes:

X-ray

Nursing Responsibilities:
- Explain procedure to patient
- Ensure patient disrobes as needed
- Ensure they remove items that will interfere with the x-ray (jewelry, metal, etc.)

MRI

Nursing Responsibilities:
During:
- Assess for adverse reactions to the dye used.
After:
- No additional care needed unless dye was used
- If dye was used, remind patients with diabetes or kidney disease to stay hydrated to flush out the dye.

Fluoroscope

Takes real-time x-ray "movies"

Arthrography

Contrast dye injected into the joint (sometimes with fluoroscopy)
Allows for visualization of inside the joint
Often a CT or MRI is performed afterward.
Often used with:
- Shoulders
- Knees
- Hips
- Elbows

MRI-Arthrogram

Specialized MRI that is used to analyze a joint.

Arthrography: Nursing Responsibilities

Before:
- Depends on the type of radiological studies being done
- A local anesthetic will be injected around the site to be punctured
- A needle will be inserted into the joint
After:
- Edema and tenderness may occur for 1-2 days
- Increase fluid intake to help excrete the contrast via the kidneys.
- A compression bandage may be applied
- Avoid strenuous activity for 48 hours

Bone Mineral Density (BMD) Measurement

Used to measure bone density with minimal radiation exposure
Used to:
- Determine the risk of fracture
- Diagnose metabolic bone disease (Osteoporosis)

BMD: Nursing Responsibilities

Same as for x-ray studies

DEXA Scanner

Specifically used for bone density measurements

Radioisotope Studies (Bone Scan)

Radioactive isotopes are injected intravenously and taken up by the bones.
Pictures are taken over several hours to detect abnormalities
Abnormalities are indicated by an accumulation of radioisotopes (dark spots)
Primarily used to diagnose:
- Cancer in the bone
- Infections in the bone
- Complicated fractures
- Osteoporosis

Bone Scan: Nursing Responsibilities

Before:
- Explain the procedure
- The technician will inject the radioisotope 2 hours before the procedure.
- The bladder should be empty
After:
- Increase fluid intake after the procedure
- The isotope will be excreted within 6-24 hours.

Arthroscopy

Invasive surgical procedure
Endoscope is inserted into the joint to enable visualization of structures.
Allows for surgical repairs as needed.

Arthroscopy: Nursing Responsibilities

Before:
- Patient needs to be NPO (nothing by mouth) after midnight
- Can be performed in an outpatient setting.
After:
- Assess for signs of pain, neurovascular function, and compression.
- Assess for pain and provide pain relief as needed.
- Keep the extremity elevated and apply ice for 24-48 hours
- Minimize exercise or use of the joint for 24-48 hours
- Monitor for complications

Blood Tests:

Mineral Metabolism:
- Alkaline Phosphatase (ALP):
  - Enzyme produced by osteoblasts
  - Elevated in healing fractures, bone cancers, and osteoporosis
- Calcium:
  - Stored primarily in bones and gives bone its rigid consistency
  - Elevated in hyperparathyroidism
Serological Studies:
- Uric Acid: End product of purine (type of protein) metabolism. Excreted by the kidneys. Usually elevated in Gout.
- Erythrocyte Sedimentation Rate (ESR): A non-specific index of inflammation.
- C-Reactive Protein: Diagnostic for inflammatory diseases, active infections, and widespread malignancy.
Muscle Enzymes:
- Creatinine Kinase (CK): Enzyme in skeletal muscle. Value increases when muscle breaks down. Associated with muscular dystrophy, polymyositis, and traumatic injuries.
- Serum Potassium (K+): Electrolyte stored inside cells. Regulates muscle contractions, nerve impulses, and fluid balance. Released into the bloodstream with muscle trauma, which increases the risk of cardiac dysrhythmias.

Invasive Procedures:

Arthrocentesis: A needle is inserted into the joint cavity.
