Study Notes
Diagnostic Studies of the Musculoskeletal System
- Various imaging techniques include radiography, CT, MRI, arthrography, and discography.
- Bone mineral density studies include DEXA and ultrasound for evaluating bone health.
- Bone scans utilize radioisotopes to detect abnormalities in bone metabolism.
- Arthroscopy provides a visual examination of joints using a small camera.
- Laboratory tests assess levels of calcium, phosphate, rheumatoid factor, and other markers.
- Invasive procedures like arthrocentesis and EMG help diagnose and evaluate musculoskeletal disorders.
Tendons and Ligaments
- Tendons connect muscles to bones, while ligaments connect bones to other bones.
- Both structures have limited blood supply, which contributes to slow healing processes.
Types of Musculoskeletal Injuries
- Common injuries include sprains, strains, dislocations, subluxations, and fractures.
Sprains and Strains
- A sprain is a tear in a ligament; a strain is a tear in a tendon.
- These injuries often occur due to joint trauma and can result in complete avulsions.
- Symptoms include inflammation at the injury site.
Clinical Manifestations of Injuries
- Typical signs include pain, swelling, reduced function, and bruising.
Healing Process for Sprains/Strains
- Healing begins with inflammation and progresses through granulation tissue formation.
- Collagen fibers develop to link bones to tendons or ligaments.
- Mild sprains/strains often heal within 3 to 6 weeks, but severe cases may require surgery.
Nursing Management for Musculoskeletal Injuries
- Health promotion includes warm-ups, stretching, balance, and strength exercises.
- Acute injury management involves the RICE method (rest, ice, compression, elevation).
- Home care includes ice application and using mild pain relief methods.
Dislocation
- A dislocation involves complete displacement of a bone from its normal position, often leading to tissue damage and significant pain.
- Prompt realignment is necessary to prevent avascular necrosis.
Subluxation
- A subluxation is an incomplete or partial displacement of a joint surface.
- Treatment includes realignment and immobilization of the joint.
Repetitive Strain Injury
- Results from repetitive motion affecting muscles, tendons, and nerves; commonly includes tendinitis and carpal tunnel syndrome.
- Treatment options involve cold/heat therapy, NSAIDs, and physiotherapy.
Fractures Overview
- A fracture is a break in bone continuity which can also impact surrounding structures.
- Hemorrhage, edema, and damage to nerves and blood vessels are common.
Fracture Classifications
- Fractures can be traumatic or pathological, with further classification by stability and completeness.
Types of Fractures
- Complete fractures involve the entire bone; incomplete fractures do not.
- Open fractures break the skin and are termed compound; closed fractures do not communicate with the external environment.
Common Fracture Patterns
- Fractures can be transverse, greenstick, displaced, depressed, or interarticular.
- Stress fractures occur from repeated stress on normal or abnormal bone.
Clinical Manifestations of Fractures
- Symptoms include pain, swelling, tenderness, deformity, and potential crepitus or paresthesia.
Assessment Protocol for Fractures
- Assessment includes inspection, palpation, X-rays, lab values, and history-taking.
Neurovascular Assessment
- Important for checking potential nerve or vessel damage; utilize the five 'P's': Pain, Pulses, Pallor, Paresthesia, Paralysis.
Bone Healing Stages
- Healing occurs in stages: hematoma formation, granulation tissue formation, procallus, bony callus, and remodeling.
Factors Affecting Healing Time
- Healing time varies by age, fracture displacement, site, and blood flow; immobilization and nutritional status influence recovery speed.
Musculoskeletal Disorders
- Degenerative disorders like osteoarthritis result from wear and tear, while autoimmune conditions occur when the immune system attacks the body’s own tissues.
