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.
