  • What should you not assume about geriatric pain?
A
  • The effects of aging on the musculoskeletal system may be counteracted, to a degree, with exercise – specifically weight/resistance training.
  • All seniors, regardless of disability should have some sort of exercise built into treatment plan
  • Don’t assume all geriatric pain is osteoarthritis! (if they are losing height then check the spine)

Q

Epidemiology of osteoporosis:
* When is low bone mass more common? What might it be related to?
* What may lead to an increase risk fracture?

A
  • Low bone mass is more common in postmenopausal women and, when present, may be related to either inadequate peak bone mass acquisition, or previous or continuing bone loss.
  • The clinical significance of isolated low bone density (without fracture) in young women is unknown. Some premenopausal women with low bone mineral density (BMD), particularly those with a known secondary cause of osteoporosis, may have abnormal bone strength that may lead to an increased risk of fracture.

Patho fracture, menopause, osteopenia= you need to look at bone den scan

Q

What is the fracture risk assessment tool (FRAX)?

A
  • The FRAX® tool has been developed to evaluate fracture risk of patients. It is based on individual patient models that integrate the risks associated with clinical risk factors as well as bone mineral density (BMD) at the femoral neck.
  • The FRAX® algorithms give the 10-year probability of fracture. The output is a 10-year probability of hip fracture and the 10-year probability of a major osteoporotic fracture (clinical spine, forearm, hip or shoulder fracture)

ex. get a 2.2 for t scale so do a frax test to help educate

A
  • Age is one of the strongest predictors of OA, with incidence of hand, hip, and knee OA increasing with age, especially after the age of 50 years.
  • Possible causes are sarcopenia, loss of proprioception, and joint laxity that may affect joint function and predispose the joint to injury. Changes affecting joint tissues include loss of normal bone structure, increased stiffness of ligaments and tendons, and meniscal degeneration.

Q
  • What are the primary symptoms of osteoarthritis (OA)?
  • Where do you they usally present?
  • What bones are most likely affected?
A
  • The primary symptoms of osteoarthritis (OA) are joint pain, stiffness lasting < 1 hour, crepitus, no systemic symptoms and locomotor restriction. ( not a systemic issue like fever, inflammation)
  • They usually present in just one or a few joints in a middle-aged or older person.
  • Hand DIP/PIP are most likely affected
    * MCP joints except thumb (1st CMC) are spared

RA is most likey to be bilateral

  • Acetaminophen vs NSAIDs (depends on risk factors, but NSAIDs are preferred)
  • Intraarticular glucocorticoid injections provide symptomatic relief but do infrequently as cartilage breakdown may be accelerated if performed too often
    * Systemic glucocorticoids have no place in Rx of OA (RA might get this)
  • Surgery last resort

NSAIDs: kideney clearance so be careful with diabetes, HTN, and kidney disease

Q

What is RA? What are the causes?

A
  • Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by an inflammatory polyarthritis that preferentially affects the small joints.
  • RA is a “multicausal” disease that most likely results from a combination of genetic predisposition and various environmental and lifestyle factors. Articular and systemic manifestations in RA can lead to poor long-term outcomes such as disability and death

Fibromyalgia Epidemiology:
* What is it?
* What is the prevalence?
* What was it initally termed? More common in who?

A
  • Fibromyalgia (FM) is a common cause of chronic pain and the most common cause of generalized, musculoskeletal pain in women between ages of 20 and 55 years
  • Prevalence is 2-3 percent and increases with age.
  • Initially termed fibrositis, FM is more common in women than men and occurs in both children and adults. It is six times more common in women

The diagnosis may be under-recognized in clinical practice according to some sources, others indicate that those that are diagnosed, only half meet the actual criteria.

PMR Epidemiology:
* Polymyalgia rheumatica (PMR) is almost exclusively a disease of adults over what?
* What is the prevalence of the disease?
* Who is more affected?

A
  • Polymyalgia rheumatica (PMR) is almost exclusively a disease of adults over the age of 50, with a prevalence that increases progressively with advancing age. The peak incidence of PMR occurs between ages 70 and 80.
  • PMR is relatively common. The lifetime risk of developing PMR has been estimated at 2.43 percent for women and 1.66 percent for men and is second only to rheumatoid arthritis (RA) as a systemic rheumatic disease in adults.
  • Women are affected two to three times more often than men. Cases of familial aggregation are recognized

Gout (monosodium urate [MSU] crystal deposition disease or Podagra) is a systemic disease characterized biochemically by extracellular fluid urate saturation, which is reflected in the blood by hyperuricemia, with serum or plasma urate concentrations exceeding 6.8 mg/dL (approximately 400 micromol/L); this level of urate is the approximate limit of urate solubility.
* Altered purine metabolism and subsequent sodium urate crystal
precipitation into Synovial fluid.
* Seen with patient consuming lots of meat/beer/seafood

124
Q

Pseudogout Epidemiology:
* How many people are affected?
* Why has an estimate of the prevalence of clinically significant CPPD disease has been more difficult to attain?
* What si the average age of diagnosis of CPPD?

A
  • Calcium pyrophosphate crystal deposition (CPPD) has been estimated to affect 4 to 7 percent of the adult populations, especially among persons of advanced age.
  • However, an estimate of the prevalence of clinically significant CPPD disease has been more difficult to attain, because the available prevalence estimates have relied primarily upon radiographically detected cartilage calcification rather than clinical evaluation, and also because prevalence data concerning patients less than about 60 years of age are not available.
  • The average age at diagnosis of CPPD disease in one study was 72 years
125
Q

Pseudogout:
* What is the etiology?
* What is the pathology?

A

Etiology
* Unknown, but thought to be secondary to elevated levels of calcium or inorganic pyrophosphate

Pathology
* CPPD crystals are found in the joint capsule and fibrocartilaginous structures associated with neutrophil infiltration and erosion

126
Q

Pseudogout Clinical Presentation:

A
  • Osteomyelitis may be classified based on the duration of illness (acute versus chronic) and the mechanism of infection (hematogenous versus nonhematogenous).
  • Acute osteomyelitis typically presents with a symptom duration of a few days or weeks. Sequestra (pieces of necrotic bone that separate from viable bone) are absent.
  • Chronic osteomyelitis is characterized by long-standing infection over months or years. Sequestra are usually present; they form as a result of bone ischemia and necrosis in the context of blood vessel compression due to elevated medullary pressure associated with bone marrow inflammation. Sequestra can be seen radiographically. The presence of a sinus tract is pathognomonic of chronic osteomyelitis.
  • Nonhematogenous osteomyelitis can occur as a result of contiguous spread of infection to bone from adjacent soft tissues and joints or via direct inoculation of infection into the bone (as a result of trauma or surgery).
  • Hematogenous osteomyelitis is caused by microorganisms that seed the bone in the setting of bacteremia.

Q

When does compartment syndrome happen?
* What compromises circulation?
* What happens if untreated?
* What is the most common site?

A
  • ACS occurs when the pressure in a muscle compartment rises sufficiently to cause tissue ischemia leading to muscle or nerve damage. Impending ACS occurs when tissue pressure has begun to increase and tissue perfusion is reduced but is not sufficient to cause muscle or nerve damage.
  • Increased pressure within the limb compromises circulation
  • If untreated – necrosis of muscle and neurologic injury
  • Most common site – anterior compartment of lower leg

  • This is an emergent condition requiring early recognition
  • Always consider Compartment Syndrome when pain increases or seems out of proportion to known injury

* What can happen? What will need to be done?

A
  • Fractured ribs (also known as cracked ribs), usually occur as a result of blunt chest wall trauma or lifestyle injuries that range from cycling to football.
  • Fractured ribs may heal on their own without treatment.
  • However, some patients have rib fractures in which bone fragments can damage major blood vessels, or structures like the lung, liver, kidneys or spleen.
  • In these cases, rib fractures usually require treatment.
248
Q

Symptoms of a rib fracture may include pain with the following actions:

A

1.Taking a deep breath
2.Pressing on the injured area
3.Bending or twisting your body

249
Q

What are the factors may increase your risk of a having a rib fracture?

A

1.Osteoporosis – this disease decreases the density of your bones, making your rib more sensitive to fractures.
2.Playing sports
3.Having an area of cancer in your rib – cancer may weaken the bone, making your rib more sensitive to fractures.

250
Q

What are the three diagnostic tests that you can do with rib fractures?

A
  • X-Ray: Rib fractures are typically diagnosed on chest x-ray with rib series and the severity of the fracture is easily seen.
  • CT Scan: CT scans may show rib fractures that were not visible on an X-ray. Injuries to blood vessels and soft tissues are easier to see on a CT scan than an X-ray.
  • MRI: An MRI can also look at the organs and soft tissues around the ribs to detect damage to these areas.
251
Q

What is the treatment for rib fractures? (nondisplaced, flail)

A
  • Most nondisplaced fractured ribs heal without surgery in one to two months and are treated with non-surgical care that ranges from aggressive pain management to proper ventilation (i.e. incentive spirometer)
