Title: Background of Anatomy and Physiology


1
Background of Anatomy and Physiology
  • Human skeleton made up of 206 bones
  • 1. Axial skeleton includes
  • a. Bones of skull
  • b. Ribs and sternum
  • c. Vertebral column
  • 2. Appendicular skeleton includes
  • a. Bones of limbs
  • b. Shoulder girdles
  • c. Pelvic girdle

2
Classification of bones by shape
3
Functions of bones
  • 1. Form structure and provide support for soft
    tissues
  • 2. Protect vital organs from injury
  • 3. Serve to move body parts by providing points
    of attachment for muscles
  • 4. Store minerals
  • 5. Serve as site for hematopoiesis
  • Bone cells include
  • 1. Osteoblasts cells that form bone
  • 2. Osteocytes cells that maintain bone matrix
  • 3. Osteoclasts cells that resorb bone

4
Clients with Musculoskeletal Disorders
  • Background
  • 1. Normal bone remodeling process involves
    sequence of bone reabsorption and formation
  • 2. Adults replace about 25 of trabecular bone
    (the porous type of bone found in the spine and
    all articulating joints) every 4 months through
    reabsorption of old bone by osteoclasts and
    formation of new bone by osteoblasts

5
Client with osteoporosis
  • Definition
  • a. Disorder characterized by loss of bone mass,
    increased bone fragility, increased risk for
    fractures
  • b. Imbalance of processes that influence bone
    growth and maintenance associated with aging,
    but may result from endocrine disorder or
    malignancy
  • c. Significant health threat for Americans
    estimated 28 million persons more common in
    aging women half of women over 50 experience
    osteoporosis-related fracture in lifetime (hip,
    wrist, vertebrae)

6
Client with osteoporosis
  • Risk Factors
  • a. Risk of developing osteoporosis depends on
    amount of bone mass achieved between ages 25 35
  • b. Unmodifiable risk factors
  • 1. Aging decrease in osteoblastic and
    osteoclastic activity related to decreasing
    levels of hormones (estrogen in females
    testosterone in males)
  • 2. Gender women have 10 15 less peak bone
    mass than men bone loss begins earlier (30s)
    and proceeds more rapidly (before menopause)
  • 3. European Americans and Asians have less bone
    density than African Americans
  • 4. Endocrine disorders affecting metabolism
    hyperthyroidism, hyperparathyroidism, Cushings
    syndrome, diabetes mellitus

7
Client with osteoporosis
  • Modifiable risk factors
  • 1. Calcium deficiency insufficient calcium in
    diet results in body removing calcium from bones
    diets high in protein lead to acidosis, and high
    in diet soda are high in phosphate
  • 2. Menopause, decreasing estrogen levels
    estrogen replacement therapy can reverse bone
    changes but may increase risk for other diseases
  • 3. Cigarette smoking decreased blood supply to
    bones
  • 4. Excessive alcohol intake toxic effect on
    osteoblastic activity high alcohol intake
    frequently associated with nutritional
    deficiencies
  • 5. Sedentary life style weight-bearing exercise
    such as walking positively influences bone
    metabolism
  • 6. Use of specific medications
    aluminum-containing antacids, corticosteroids,
    anticonvulsants, prolonged heparin therapy,
    antiretroviral

8

    osteoclastic activity and is indicator of rate of
    bone turnover used to evaluate effects of
    treatment

12
Client with osteoporosis
  • Medications
  • a. Estrogen replacement therapy reduces bone
    loss, increases bone density in spine and hip,
    reducing risk of fractures in postmenopausal
    women.

70
Client with an Amputation
  • Partial or total removal of body part resulting
    from traumatic event or chronic condition
  • B. Causes of amputation
  • 1. PVD is major cause
  • 2. Trauma is major cause of upper extremity
    amputation
  • 3. Other traumatic events resulting in amputation
    include frostbite, burns, electrocution
  • C. Underlying cause of amputation is interruption
    in blood flow either acute or chronic

71
Client with an Amputation
  • Levels of amputation
  • 1. Determined by local (ischemia and gangrene)
    and system factors (cardiovascular status, renal
    function, severity of diabetes mellitus)
  • 2. Goals
  • a. Alleviate symptoms
  • b. Maintain health tissue
  • c. Increase functional outcome joints are
    preserved whenever possible to allow for greater
    function
  • Types of amputation
  • 1. Open (guillotine) performed when infection is
    present and remains open to drain
  • 2. Closed (flap) wound is closed with flap of
    skin sutured in place over stump

72
Common sites of amputation
73
Client with an Amputation
  • Amputation site healing
  • 1. Immediate post-operative assess circulation
    to stump
  • 2. Rigid or compression dressing is applied to
    prevent infection and minimize edema
  • 3. Stump is wrapped in Ace bandage to allow a
    conical shape to form and prevent edema applied
    from distal to the proximal extremity

74
Client with an Amputation
  • Complications
  • 1. Infection
  • a. Local
  • 1. Drainage or odor
  • 2. Redness
  • 3. Positive wound culture
  • 4. Increased discomfort at suture line
  • b. System
  • 1. Fever, chills
  • 2. Increased heart rate or decreased blood
    pressure
  • 3. Positive wound or blood cultures

75
Client with an Amputation
  • Delayed healing
  • a. Slower rate of healing than normal
  • b. Factors include
  • 1. Poor or inadequate nutrition
  • 2. Poor blood flow, possibly related to smoking
  • 3. Decreased cardiac output limits circulation
  • Chronic stump pain
  • a. Results from neuroma formation causing severe
    burning pain
  • b. Treatments include
  • 1. Medications
  • 2. Nerve blocks
  • 3. Transcutaneous electrical nerve stimulation
    (TENS)
  • 4. Surgical stump reconstruction

76
Client with an Amputation
  • Phantom limb pain/ phantom limb sensation
  • a. Majority of amputees have sensations such as
    tingling, numbness, cramping or itching in the
    phantom foot or hand, often self-limited
  • b. Phantom limb pain is pain often difficult to
    treat may be referred to pain clinic for
    comprehensive pain management

77
Client with an Amputation
  • Contracture
  • a. Abnormal flexion and fixation of joint caused
    by muscle atrophy and shortening
  • b. Common complication associated with above the
    knee amputation
  • c. Interventions include
  • 1. Lying prone for periods throughout day
  • 2. Active and passive range of motion
  • 3. Avoid prolonged sitting

78
Client with an Amputation
  • Prosthesis
  • a. Type depends on level of amputation, clients
    occupation and life style
  • b. Client with lower extremity amputation often
    fitted with early walking aids pneumatic device
    that fits over stump and allows early ambulation,
    decreased postoperative swelling
