Skeletal Disorders

May Occur with Bone, Cartilage, Ligaments, Joints

tumors cancers
Tumors & Cancers
  • Osteosarcoma
    • Common
    • Fatal
tumors cancers1
Tumors & Cancers
  • Chondrosarcoma
    • Skeletal Cartilage Cancer
tumors cancers2
Tumors & Cancers
  • Fibrosarcoma
    • Malignant
    • Bone Marrow
    • Excessive Connective Tissue Production
osteoporosis
Osteoporosis
  • Most Common & Serious
    • “Condition of bone pores”
osteoporosis1
Osteoporosis
  • Excessive loss of calcium & collagen fibers
    • Decrease in bone volume / Holes
osteoporosis2
Osteoporosis
  • Bones are brittle & easily broken
    • Spontaneous Fractures
    • Femur & Vertebrae
osteoporosis3
Osteoporosis
  • Most frequently in white elderly women
    • Decreasing sex hormones reduces bone growth and bone mass maintenance
    • Kyphosis most notable outward sign
      • Shrink
osteomalacia
Osteomalacia
  • Decrease in Hard Minerals
    • Bone volume remains the same
  • Demineralization
  • Vitamin D deficiency
    • Required to absorb Ca and P
slide10
In children, it is called Rickets
  • Bone Deformities
  • Ca imbalance can lead to death
paget disease
Paget Disease
  • Also called Osteitis deformans
  • Affects Older Adults
  • Characterized by abnormal bone remodeling
osteomyelitis
Osteomyelitis
  • Bacterial infections of bone and marrow tissue
  • Staphylococcus most common
  • Difficult to treat due to bone density and slow healing
bone fractures
Bone Fractures
  • Open Fractures
    • The bone pierces the skin
    • Compound
  • Closed Fractures
    • The bone does not pierce the skin
    • Simple
  • Complete
    • Displacement
  • Incomplete
    • No Displacement
fracture types
Fracture Types
  • Greenstick
    • Bone is broken only on one side
  • Comminuted
    • Break that produces many fragments
  • Impacted
    • Bone fragments are driven into each other
  • Transverse
    • Fracture is at a right angle to the bone’s long axis
  • Oblique
    • Fracture is diagonal to the bone’s long axis
joint disorders

Joint Disorders

Non-inflammatory

&

Inflammatory

noninflammatory joint disease
Noninflammatory Joint Disease
  • Does NOT inflame the Synovial Membrane
osteoarthritis
Osteoarthritis
  • Also known as degenerative joint disease
  • Most Common
  • Degeneration of the articular cartilage
  • Advanced Age, Joint Damage, Joint Stress
dislocation
Dislocation
  • When the articular surfaces of bones are no longer in proper contact
  • Bone stays OUT of the joint
  • SUBLUXATION
    • Reduces on its own
sprain
Sprain
  • An acute injury to the ligaments around a joint
  • Tear of the Ligament
inflammatory joint disease
Inflammatory Joint Disease
  • Arthritis
  • Inflammed Synovial Membrane
  • Many causes
    • Infection
    • Genetics
    • Autoimmunity
rheumatoid arthritis
Rheumatoid Arthritis
  • Autoimmune Disorder
  • Chromic inflammation of connective tissues
    • Begins in the synovial membrane
    • Spreads to cartilage & other tissues
  • Crippling
  • Juvenile Rheumatoid Arthritis
    • More Severe
    • More Common in Girls
gouty arthritis
Gouty Arthritis
  • Gout
  • Metabolic Condition
  • Increase in Uric Acid in Blood
    • Alcohol, Sweet, Fat
    • Sodium Urate Crystals deposited in Distal Joints
    • Trigger Chronic Inflammation
infectious arthritis
Infectious Arthritis
  • Pathogens cause synovial infection
  • Joint Deterioration
  • Most Common Bacterial
  • Other Signs & Symptoms
  • Lyme Disease
    • Ticks
