Normal Bone Health
The body maintains healthy bone by a process of repair (called remodeling)
Driven by two types of bone cells:
Osteoclasts:
Responsible for removing (resorption) of old existing bone
Osteoblasts:
Responsible for forming new bone
A balance between the activities of osteoclasts keeps the overall mass of bone in the body constant
Arthritis = inflammation of a joint
Several types, most common is osteoarthritis or wear-and-tear arthritis
Pennis =
SYMPTOMS:
Affects various joints in the body
Common to have initial onset symptoms at the joint at the base of the thumb
Common symptoms of arthritis/osteoarthritis include:
Joint pain that often gets worse after exercise or excessive pressure on a joint
Joint stiffness particularly in the morning
Cracking or grinding noise with joint movement
Decreased function of the joint
Causes & risk factors:
Over 40 years can affect people of all ages
Most common cause is wear-and-tear, and as you age, you are more prone to develop arthritis
Traumatic injuries, fractures, & joint dislocation make you more susceptible to develop arthritis
Certain types of arthritis are more common in women than men (such as arthritis in the thumb)
Some people have congenital abnormalities of the joints-for example. Perthes’ disease of the hips, that cause early degeneration & subsequently can cause osteoarthritis
Rheumatoid Arthritis (RA)
RA is an auto-immune disease in which the body’s immune system (the body’s way of fighting infection) attacks healthy joints, tissues, & organs – heart, lungs, gastrointestinal system
Most often in women of childbearing age, the disease inflames the lining (or synovium) of joints (2-3x more women)
Can happen at any age, primarily between 25-45 years crippling disability that impairs a person’s ability to stay active & independent & may shorten a person’s lifespan
Pain, stiffness, swelling, & loss of function in joints
Severe RA can deform/change a joint
Affects mostly joints of the hands & feet & tends to be symmetrical (no other form of arthritis is symmetrical)
RA is one of more than 100 forms of arthritis affecting millions of Americans
Deformities:
Swan neck
PIP hyperextension
DIP flexion
Dorsal migration of the lateral bands
Boutonniere deformity
PIP flexion
DIP hyperextension
Lateral bands migrate volar
Diagnosis:
2 main tests:
Rheumatoid Factor
Anti-cyclic citrullinated peptide (anti-CCP)
Medical history - patient narrative; physical exam; blood test, imaging tests
Medications: pain-relieving medications such as NSAIDs, DMARDS, COX-2 inhibitors & opioids may be prescribed.
Topical medications such as ointments can be applied over the skin where there is pain
If the pain is very severe, corticosteroid injection can be given directly into the affected joint to ease pain
Surgery:
joint replacement
Therapy
Exercise to keep joints flexible & improve muscle strength
Applying heat to affected joints for temporary pain relief
Lifestyle modifications to control weight & avoid extra stress on the weight-bearing joints
AE
RA is a systemic disease which damages more than joints, can also affect internal organs such the heart, lungs, liver, or vascular system
RA has been associated with cardiovascular disease, heart failure, lung disease, eye disorders, fibromyalgia, depression, & more
Patients with RA need to attend to their cardiovascular health by controlling high cholesterol, eating a heart-healthy diet, & getting regular exercise
Heart disease is the leading cause of death among people diagnosed with RA
****can increase the risk of cardiovascular disease (RA is a systemic disease that can damage more than joints)
Rheumatoid Arthritis = bone loss
The inflammatory process that occurs in RA increases the risk of bone loss & fractures
Severity of inflammation
Duration of disease
GOALS for RA:
Stop inflammation (put disease in remission)
Relieve symptoms
Prevent joint & organ damage
Improve physical function & overall well-being
Reduce long-term complications
Control inflammation
Increased amount of calcium
RA = Osteoporosis
Osteoporosis, with increased risk of fracture, commonly affects women with RA
This is especially true as this group reaches menopause & during the post- menopause years, when the risk for osteoporosis is normally the highest
Osteoporosis is a condition in which the bones become less dense & more likely to fracture
In the US, more than 53 million people either already have osteoporosis or are at high risk due to low bone mass
Gout
Metabolic syndrome
Most common form of arthritis
Crystalline form of inflammatory arthritis
First appearance = significant pain in MTP of big toe
Related to how the body metabolizes food
Will have periods of flare ups & remissions
Associated with “rich man’s diet”
AMAB are 3x more likely to develop gout
African AMerican AMAB more likely than caucasian AMAB
Signs & symptoms
Reddish purple tone
Increased with age
Increases medication utilization & cost
Interconnected to other diseases
Maintained by medication but not well controlled by US
Diagnosed through physical exam, medical history, and lab/blood work
Imaging can also be used for more severe & chronic forms of gout
Presence of uric acid crystals in synovial fluid & elevated leukocytes & neutrophils
Episodic & chronic components
A form of inflammatory arthritis, & some people have high levels of uric acid in the blood
The acid can form needle-like crystals in a joint and cause sudden, severe episodes of pain, tenderness, redness, warmth, & swelling
Stages of gout:
Asymptomatic hyperuricemia
The period prior to the first gout attack
Acute gout, or gout attack
Happens when something (such as a night of drinking) causes uric acid levels to spike or jostles the crystals that have formed in a joint, triggering the attack
Interval gout
The time between attacks
Chronic gout
Develops in people with gout whose uric acid levels remain high over a number of years
Prevalence: occurs in about 4% of American adults – about 6 million men & 2 million women. Experts believe natural estrogen protects women up to that point
Risk factors:
Genes: if family members have gout, you're more likely to develop it
Other health conditions: high cholesterol, high blood pressure, diabetes & heart disease may increase your risk
Medications: diuretic medications of “water pills” taken for high blood pressure can raise uric acid levels; so can some drugs that suppress the immune system taken by rheumatoid arthritis & psoriasis patients, as well as transplant recipients
Diet: eating red meat and shellfish increases your risk
Alcohol: for most people, more than two liquor drinks or two beers a day can increase the risk of gout
Sodas: the fructose in sweet sodas has recently been shown to increase gout risk
Obesity: obese people are at higher risk for gout, & they tend to develop it at a younger age than people of normal weight
Bypass surgery: those who have undergone gastric bypass surgery have an increased risk
Lupus
A chronic, autoimmune disease, with an overactive & misdirected immune system
Lupus is systemic, meaning that it affects a wide part of the body, including the joints, kidneys, skin, blood, & other organs
Systemic lupus erythematosus (SLE)
Accounts for about 70% of all lupus cases
Considered most serious form of lupus but range from very mild to severe
SLE affects various parts of the body and can cause joint pain, fatigue, hair loss, sensitivity to light, fever, rash, & kidney problems
Prevalence:
More than 1.5 million Americans have lupus
Across all ethnic, age, and sexes; 9 out of 10 adults with the disease are women between ages 15 and 45
Systemic lupus erythematosus
Pain & inflammation in any part of the body
Autoimmune disease
Symptoms can come & go and vary in severity
Autoimmune disease that does not have an etiology but has contributing factors
More common in AFAB (a lot of research being done with the association with estrogen)
Runs in families
Health disparities can impact severity of disease presentation and reduced QoL
Symptoms include:
Severe & prolonged fatigue
Stiffness & pain in hands, wrists, elbows, & knees
Other symptoms:
Butterfly rash across nose & cheeks
Fever
Sunlight sensitivity
Raynaud’s phenomenon
Mouth sores
Swollen glands
Trouble breathing
Kidney issues
Cognitive deficits (memory issues)
Blood disorders
Vaginal dryness
Swelling in legs & around eyes
Cough
Lupus Nephritis
Inflammation of NS
Inflammation of blood vessels
Hardening of arteries
Skin inflammation
Diagnosing lupus can take an average of 6 years to be diagnosed
Typically requires:
Review of symptoms
Medical history
Family history
Lab tests
3 categories of classifications of lupus
Quiescent
Stable
Serious
Juvenile Idiopathic Arthritis (AKA Juvenile RA)
Types of JIA
Oligoarticular or pauciarticular JIA (most common type of arthritis in children under 16 y/os)
Polyarticular JIA
Enthesitis-related arthritis (ERA)
Psoriatic JIA
Systemic JIA (still disease)
Some types can cause complications with growth, joint damage, and eye inflammation
Many other forms of juvenile inflammatory arthritic conditions
Has genetic & environmental factors play a role in JIA
Affects AFAB more than AMAB
More common in caucasian populations than African American populations
Signs & symptoms:
Fever
Joint swelling & stiffness
Swollen lymph nodes
Rash
Diagnosis = rule out method
Fractures
Caused by trauma or disease of bone or joint
2 factors to determine a fracture:
Amount of force applied to bone
Strength of the bone
As you age = bone mass will decrease
Force applied can be from high energy, low energy, and/or chronic stress
Stress fractures most often result from overuse or repetitive stress on the bone
They often result from any increased amount or intensity of activity that occurs too rapidly to give the bone a chance to adjust
More common in lower extremities
Osteoarthritis = most common
Also a degenerative joint disease
Older adults
Affects cartilage (the tissue that cushions & protects the ends of bones in a joint)
With osteoarthritis, the cartilage wears away over time
Bone-on-bone contact
Bones may also bulge, or stick out at the end of a joint = bone spur
Joint pain can limit ROM (the ability to freely move and bend a joint)
Disability most often happens when the disease affects the spine, knees, & hips
Osteopenia:
Reversible bone weakness
Decrease in bone density
Precursor to osteoporosis
Heterotopic Ossification:
Abnormal bone formation in soft tissues
Associated with traumatic injuries
Can be painful & debilitating depending on the severity
Types of fractures:
Hairline
Greenstick
Closed
Open
displaced/unstable
nondisplaced/stable
Comminuted
Spiral
Occupational Therapy: Arthritis
Joint protection
Adaptive techniques/equipment
Conditioning programs/exercise
Education
Community mobility/driving
Splints
psychosocial/ coping/ sleep
Pain reduction
ADL/IADL
vocational/ workplace assessments
Key Principles for Prevention of Joint & Protection of Joints
Avoid forceful activities
Avoid tight grasps
Avoid using pressure side of thumb
Always use your largest joints
Use 2 hands for lifting instead of 1
Slide heavy items instead of carrying
