Care of the Patient With a Musculoskeletal Disorder
Functions of the Skeletal System
Support: Provides framework for internal tissues and organs.
Protection: Shields internal structures (e.g., cranium protects brain).
Movement: Enables leverage for movement through muscle attachments.
Mineral Storage: Stores minerals like calcium and phosphorus; releases when needed.
Hematopoiesis: Blood cell formation occurs in red bone marrow, which may convert to yellow with age.
Divisions of the Skeletal System
Axial Skeleton
Composed of skull, hyoid bone, vertebral column, thorax.
Appendicular Skeleton
Composed of upper and lower extremities, shoulder girdle, pelvic girdle.
Structure of the Musculoskeletal System
Bones and Joints: Framework of the body.
Muscles: Necessary for movement and contraction.
Types of Body Movements: Flexion, extension, abduction, adduction, rotation, supination, pronation, dorsiflexion, plantar flexion.
Functions of the Muscular System
Motion: Facilitates body movements.
Maintenance of Posture: Supports standing upright.
Production of Heat: Assists in thermoregulation—important for physiological function.
Venous Return: Aids in the return of blood to the heart.
Diagnostic Examinations for Musculoskeletal System
X-ray
Laminography
Scanography
Myelogram
Nuclear scanning
MRI
Computed tomography
Bone scan
Aspiration (including synovial fluid aspiration)
Endoscopic examination
Types of Arthritis
Rheumatoid Arthritis
Serious form of arthritis that leads to crippling.
Characterized by chronic inflammation of synovial membranes.
Osteoarthritis
Degenerative joint disease; nonsystemic and noninflammatory.
Commonly affects hand, knee, hip, cervical, and lumbar joints.
Symptoms: Pain and stiffness.
Gouty Arthritis (Gout)
Caused by uric acid accumulation.
More common in men; onset often at night.
Symptoms: Excruciating pain and swelling in joints.
Osteoporosis
Disorder resulting in loss of bone density.
High-risk group: Women aged 55-65.
Bone Healing Process
Hematoma Formation: Bleeding at fracture site.
Organization: Hematoma organizes and forms a fibrin network.
Callus Formation: Osteoblasts enter and create a callus.
Remodeling: Bone is strengthened and reformed.
Common Soft Tissue Injuries
Contusions
Most common injury; severity varies.
Management: Ice application for vasoconstriction.
Sprains
Result from joint hyperextension; can cause hemarthrosis.
Management (RICE): Rest, Ice, Compression, Elevation.
Strains
Microscopic tears from overstretching.
Symptoms: Soreness, stiffness, tenderness.
Dislocations
Subluxation: Partial dislocation.
May require closed reduction or surgery for correction.
Phantom Pain
Occurs in amputees; nerves send pain messages despite absent limb.
Spine Deformities
Kyphosis: Rounded thoracic spine.
Scoliosis: Lateral curvature.
Lordosis: Lumbar spine curvature.
Degenerative Diseases
Conditions such as Multiple Sclerosis, Parkinson's, etc., affecting nervous system health.
Multiple Sclerosis (MS)
Attacks central nervous system; damages myelin.
Symptoms vary; includes fatigue and mobility issues.
