What is bending, DECREASING the joint angle between bones?

carpal tunnel syndrome
Carpal Tunnel Syndrome

Nerve entrapment at the wrist that results in compression of the median nerve in the carpal tunnel.

The compression causes sensory & motor changes in the hand (palm & middle finger)

Usually 30 – 60 years of age

More common in assembly workers, packers

Chronic repetitious motion

slide11

Aggravating factors: sustained grasping, twisting, flexing

  • Pathology: inflammation of the tendon sheaths that pass through the carpal tunnel causes edema & compression of the median nerve
  • Related illnesses that can cause CTS:
    • Pregnancy Acromegaly
    • RA Colles fractures
    • Renal failure hypothyroidism
    • DM TB menopause
slide12

Symptoms

    • Numbness
    • Weakness
    • Pain in hand (in the thumb, forefinger, middle finger, ½ 4th finger)
    • Patient can’t clench a fist
    • Worse at night
slide13

Testing

    • Decreased sensation to light touch & pinpricks
    • Palm muscle atrophy
    • Positive Tinel’s sign
    • Phalen’s wrist flexion test
    • Compression test
      • Bp cuff inflated above systolic pressure on the are for 1 – 2 minutes provokes pain & paresthesia along the median nerve
    • EMG
      • Median nerve conduction delay of more than 5 milliseconds
slide14

Treatment

    • Splinting the hand for 1 – 2 weeks
    • Possible alteration of work environment
    • NSAIDS (non-steroidal anti-inflammatory drugs)
    • Steroid injections
    • Surgical intervention
      • Decompression of the nerve by resecting the transverse carpal tunnel ligament
slide15
GOUT
  • Metabolic disorder marked by red, swollen, & acutely swollen, painful joints
  • Most common joints are:
    • Feet
    • Great toe
    • Ankle
    • midfoot
slide16

Most commonly affects men older than 30 yo & post-menopausal women that take diuretics

  • Patients may be symptom – free between attacks
  • Underlying Cause: Primary is Unknown
  • Pathology: decreased excretion of uric acid by the kidneys ; some patients have an overproduction of uric acid
  • Secondary gout develops from another disease
    • Obesity Leukemia bone ca
    • DM HTN renal disease
4 stages of untreated gout
4 stages of Untreated Gout

Patient develops hyperuricemia with no symptoms

Acute gouty arthritis; painful swelling & tenderness.

Interictal stage (may last for 6 months) – patient may be asymptomatic or have flare ups

Chronic Stage – urate pooling causing tophi (clusters of urate surrounded by inflamed tissue) to develop in cartilage, synovial membranes, tendons, & soft tissues

slide18

Factors that make it worse

    • Stress
    • Trauma
    • Infection
    • Hospitalization
    • Surger
    • Starvation
    • Excessive intake of foods with purine
    • Alcohol
    • Some medications
slide19

Purine-Rich Foods

According to the American Medical Association, purine-containing foods include:

Beer, other alcoholic beverages.

Anchovies, sardines in oil, fish roes, herring.

Yeast.

Organ meat (liver, kidneys, sweetbreads)

Legumes (dried beans, peas)

Meat extracts, consomme, gravies.

Mushrooms, spinach, asparagus, cauliflower.

Beneficial Foods

Foods which may be beneficial to people with gout include:

Dark berries may contain chemicals that lower uric acid and reduce inflammation.

Tofu which is made from soybeans may be a better choice than meats.

Certain fatty acids found in certain fish such as salmon, flax or olive oil, or nuts may possess some anti-inflammatory benefits.

Testing

    • Needle – aspiration of synovial fluid (arthrocentesis)for crystalof sodium urate
    • Blood & urine analysis (for uric acid levels)
    • X – rays
      • Normal in acute gout; joint changes in chronic
  • Treatment
    • Dietary changes Acetaminophen
    • Weight loss Corticosteroids
    • Cold to inflammation sites
    • Immobilize joints Colchicine
colchicine
Colchicine

Relieves inflammation of acute gout arthritis

Side effects: Rash, diarrhea, blood disorders

Encourage patient to increase fluid intake to excrete excessive uric acid

allopurinol
Allopurinol
  • Generic name: Zyloprim
  • Treats chronic Gout
  • Decreases serum & urine levels of uric acid
  • Used in chronic management of gout
  • SE
    • Rash Allergic reaction N/V
    • Fever, chills diarrhea drowsiness vertigo
  • Contraindications – impaired renal function, pregnancy, liver disease, hypersensitivity
  • Interactions
    • Alcohol, diuretics, anti-neoplastic drugs
osteoarthritis
Osteoarthritis

Most common form of arthritis

Equal in males & females

Usually over the age of 40

Secondary: usually result from trauma, congenital deformity, obesity

Deterioration of the joint cartilage & formation of new bone at margins of joints

slide24

Symptoms

osteoporosis
Osteoporosis
  • Metabolic bone disorder in which bone resorption accelerates & bone formation decellerates
  • Decrease in bone mass
  • 4 x more common in women than men
  • The bones lose:
    • CA
    • P
    • Bones become more porous & brittle making them more prone to fractures
slide33

Causes – primary is unknown

  • Contributing factors
    • Mild but prolonged lack of calcium
      • Due to diet
      • Slow absorption
    • Hormonal imbalance
    • Faulty metabolism of protein due to estrogen deficiency
    • Sedentary lifestyle
slide34

Primary osteoporosis has 3 types:

    • Type I: Postmenopausal
      • Women 51 – 75 yo
      • Due to loss of estrogen
      • Usually vertebral & wrist fx
    • Type II: Senile
      • Wome 70 – 85 yo
      • Osteoblasts & osteoclasts shrinkage
      • Fractures of the humerus, tibia, femur, & pelvis
    • Type III: Premenopausal
      • Higher estrogen levels
      • Increase bone resorption due to osteoclasts not responding to the parathyroid hormone
slide35

Diagnostic tests

    • X – ray show degeneration of lower vertebrae
    • Serum Ca, P, & Alkaline phosphatase levels may be WNL
    • Parathyroid hormone levels may be elevated
    • Bone biopsy
    • CT Scan
    • RULE OUT: other causes for bone disease such as cancer or tumors
slide36

Treatment

    • Goals
      • Control bone loss
      • Prevent fractures
      • Control pain
