Q

Definition and symptoms of peripheral neuropathy

A

-Peripheral neuropathy affects about 20 million people in the US
-Develops from damage to the peripheral nervous system
Symptoms: range from numbness/tingling, paresthesia (prickling sensation/pins + needs), muscle weakness
-pain, allodynia -may affect internal organs (autonomic system: digestion, urination, etc.)
-may lead to paralysis, muscle sweating, organ dysfunction and failure

Q

wrist injuries

A

wrist sprains & scaphoid- scaphoid is a retrograde blood supply; 70-80% of blood supply comes from the dorsal carpal branch of the radial artery; 20-30% of total supply come from the palmar and superficial palmar branches (radial artery) & doesn’t reach the proximal pole

Scaphoid fracture- blood flow characteristics present a problem w/ a scaphoid fracture
-with blood flow disruption, healing can be slow or not heal at all

Signs: presents with deep, dull pain in the radial side of the wrist usually worsens with gripping/squeezing
Swelling is typically present and bruising is visible
-tenderness to palpation of anatomical snuffbox

Q

chronic shoulder instability

A

shoulder is the most moveable joint in your body, and because of that, one of the most unstable
injury may not be complete dislocation, partial dislocation is called subluxation
once the ligaments, tendons, and muscles around the shoulder become loose or torn from repeated injury, dislocations can reoccur

Chronic shoulder instability is the persistent inability of these issues to keep the arm centered in the shoulder pocket

Q

Boutonniere deformity

A

caused by forceful blow to bent finger (jammed finger)

  • rupture of central slip causes the extrinsic extension mechanism from the extensor digitorum communis (EDC) to be lost
  • prevents extension at the PIP joint
  • weakening of triangular ligament causes intrinsic muscles of the hand (lumbricals) to act as flexors at the PIP joint
  • lumbricals also extend the DIP joint without an opposing or balancing force
  • palmar migration of collateral bands and lateral bands causes lumbricals pull to become unopposed

Skier’s (snow)/ Gamekeeper’s thumb
injury to the ulnar collateral ligament of the thumb MP joint
26
fractures
may be simple, aligned and stable other fractures are unstable and the bone fragments tend to displace/shift Comminuted fractures (bone is shattered into many pieces) usually occur from a high energy force and are often unstable Open (compound) fracture occurs when a bone fragment breaks through the skin; there is some risk of infection with compound fractures
27
may be a family trait and harmless, but if it develops, it may be associated with lung disease -inflammatory bowel disease -heart disease -liver disease -AIDS
Clubbing
28
associated with; cardiovascular disease, collagen vascular disease, prednisone use, cardiac failure, COPD, etc. absent lunula may indicate...
red lunula anemia or malnutrition
29
may be a sign of: | -anemia -congestive heart failure -liver disease -malnutrition
pale nails
30
may indicate | -Raynaud’s disease, respiratory disorders, cardiovascular disorders
bluish nails (cyanosis)
31
associated with bacterial endocarditis (heart valve infection), trauma, mitral stenosis, vasculitis, cirrhosis, scurvy
splinter hemorrhage
32
painful, red and swollen nail fold, or skin that surrounds nail - may be acute, few hours - or chronic, more than 6 weeks - infection, injury or irritation - eczema or psoriasis
paronychia
33
nail bed bleeds (injury), under nail creating a hematoma (blood outside BV) -fractures of the fingertip ( tuft fracture) usually heal by rest (splint may be needed)
crushed fingertips- Subungual hematoma
34
sudden pull on a finger ring, results in severe soft tissue injury ranging from circumferential soft tissue laceration to complete amputation -skin, nerves, vessels are often damaged
ring avulsion injury
35
Tendon Repairs
``` 1) zones: Zone 1 – 5 zone 1: tips of fingers zone 2: no man’s land Zone 3: lumbrical origin Zone 4: carpal tunnel zone 5: proximal to carpal tunnel ``` 2) type of splint used for flexor tendon repair= dorsal block splint (slide 12/31)
36
Rotator cuff:
arthroscopic repair- benefits of arthroscopic surgery vs. traditional surgery - surgical repair of the torn rotator cuff which often involves reattaching the tendon to the head of humerus - a partial tear, however, may need only a trimming or smoothing procedure arthroscopy can assess and treat damage to other structures within the joint: - bone spurs are often removed arthroscopically - no need to detach deltoid muscle with mini-open repair
37
Fractures fixations
Internal fixation- to stabilize a long bone fracture, a plate and screws outside the bone or a rod inside the bone may be used External fixation- screws are placed into the bone above the fracture, and a device is attached to the screws from outside the skin, where it may be adjusted to realign the bone
38
involves replacing the ball portion of the hip joint, not the socket portion
Hemiarthroplasty
39
replaces the acetabulum and femoral head
THA
40
THA indications
Dull ache pain to groin and buttock areas - pain especially at night is the principal indication - post op relief as early as 1 week Functional Limitations -walking and walking upstairs becomes difficult -bending at hips, putting on shoes, pedicure, etc. Stiffness- hip stiffness -ankylosing spondylitis: abnormal stiffening of the joint due to the bones can leave patients with tremendous functional disability in the absence of pain Age- most hip replacements performed in patients between 60-80 years old Radiographic image- severity of radiographic changes of arthritis within the hip joint may or may not be an indication -severity of symptoms a more important indicator
41
principal indication of THA
pain esp at night
42
Torn ACL Mechanism of Injury
Typically torn in noncontact deceleration that produces a valgus twisting injury e.g., when landing on the leg and quickly pivoting in the opposite direction Other forces can disrupt ACL with minimal injury to other structures -hyperextension -marked internal rotation of tibia on femur -pure deceleration
43
ACL gender differences
- rate of ACL injury 2-8x higher in females than males - patellofemoral pain, instability, and arthritis women have a narrow intercondylar notch width and wider Q angle ( a risk factor for patella subluxation)
44
Types of ACL Injury
Grade 1 sprain- mildly damaged, slightly stretched, but still stabilize Grade 2 sprain- stretched n loose “partial tear” Grade 3 sprain- most common, complete tear to 2 pieces, unstable
45
Meniscus Tears
Function: shock absorber, helps optimize force across the knee -protects the cartilage at the end of the femur Meniscus Tears- causes: -squat, wisting, and tackle (direct force on knee) -older ppl have degenerative meniscus tears -cartilage weakens and wears thin over time
46
Hip Fractures
femoral neck intertrochanteric subtrochanteric fractures
47
femoral neck hip fractures
fractures of the femoral neck can entirely disrupt the blood supply to the femoral head - resulting in major healing complications such as fracture nonunion or avascular necrosis - or death of femoral head bone tissue
48
intertrochanteric fractures
extrascapular - involve bone with good local blood supply - however, complicated by the pull of muscle attachments, which can pull fracture out of alignment - healing complications may include; shortening of the length of the femur or malunion
49
subtrochanteric fractures
blood supply to subtrochanteric region not as good as the intertrochanteric region - heals more slowly - subject to competing muscular forces on the femur that tend to pull the fractured fragments out of alignment
50
Late stage deformities of the hand associated with RA:
- boutonniere deformity of thumb - ulnar deviation of metacarpophalangeal joints - swan-neck deformity - bone erosion and displacement
51
Difference between osteoarthritis and RA:
Osteoarthritis- bone ends rub together & thinned cartilage RA- bone erosion & swollen inflamed synovial membrane, autoimmune
52
Pharmacological Treatment of RA:
3 classes of drugs commonly used 1) NSAIDS 2) Corticosteroids - both have short onset of action 3) DMARDs- takes weeks or months to demonstrate clinical effect
53
Types of debridement:
1. Autolytic- body’s own healing process to remove tissue – moist dressing 2. Enzymatic- chemical enzymes, such as ointment, to help slough off dead tissue- ointment- can strip away healthy tissue 3. Surgical- surgical removal of dead tissue 4. Mechanical- wet to dry dressing regularly changed- can strip healthy tissue away 5. Maggot- using larvae to remove dead tissue
54
most common type of chronic wound
ulcers
55
Arterial Ulcers (poor blood supply!)
-poor delivery of nutrient-rich blood to the lower extremities ex) hypertension, atherosclerosis (plugging) and thrombosis (clotting) -where reduced blood supply leads to an ischemic state Usually involve full thickness skin -having a punched-out appearance with smooth edges In some cases, ischemia (poor circulation to area) is present
56
Venous Ulcers
account for more than half of ulcer cases, especially in lower limbs -as associated with deep vein thrombosis, varicose veins and venous hypertension Venous ulcers can lead to stasis- stoppage or slowdown of blood flow shiny smooth skin w no hair superficial, shallow and irregularly shaped with pain and edema
57
Diabetic Ulcers
common complication is uncontrolled diabetes mellitus -resulting in impaired immune function, ischemia, neuropathy, which can eventually lead to ulceration Origin can be neuropathic (secondary to nerve damage) - where lack of sweat makes the skin dry forming callus - callus area can eventually form into an ulcer
58
Pressure/Decubitus Ulcers
constant pressure and friction resulting from body weight over a localized area for prolonged duration -can lead to breakage of skin and ulceration (bed sores) Especially on back, ankles and feet
59
Superficial burn
superficial/epidermal burn (first-degree) | -painful
60
Superficial Partial-thickness burn
``` superficial dermis (second-degree) -painful to temperature, air and touch ```
61
Deep Partial-thickness burn
all of epidermis and some of dermis (second-degree) | -painful to pressure only
62
Full-thickness Burn
all of epidermis and all of dermis | -deep pressure only
63
Deeper Injury
fascia and or muscle (fourth-degree burns) | -deep pressure
64
A gold standard temporary skin substitute is
cadaver allografts (cells are alive or viable)- 4 weeks
65
skin from a different species (pig)
Skin Xenografts (heterograft):
66
Skin Substitute vs Skin Replacement
skin replacement: a tissue or graft that permanently replaces lost skin with healthy skin Autograft (graft of tissue from one point to another of the same person’s body) Allograft (tissue from the same species- can be from a cadaver, living related or unrelated donor) skin substitute: a biomaterial, engineered tissue or combination of materials and cells or tissues that can be substituted for skin
67
Most common cause of limb loss:
``` -Dysvascular related amputations Amputation levels: 1. interscapulothoracic 2. Shoulder disarticulation 3. transhumeral (above elbow) 4. Elbow disarticulation 5. transradial (below elbow) 6. wrist disarticulation 7. transcarpal (partial hand) 8. finger amputations ```
68
No prosthesis
- bad first experience -unnatural look -reactions from others - development of one-handedness -financial concerns

Stages of cancer & meaning of each stage
``` Based on size and if it has spreads Used in research and treatment Cancers are staged when they are first diagnosed Stage does not change as cancer progresses TNM: Tumor size Nodal involvement Metastasis ``` Stages: 0-IV
77
most common type; occurs when heart is working harder than usual -has a regular pattern
stable angina
78
doesn’t follow a pattern; may occur more often and be more severe than stable angina - can occur with or without physical exertion, often when sleeping/resting, surprise - rest/medicine may not relieve pain; very dangerous - a sign heart attack may happen soon
unstable angina
79
rare; spasm in coronary artery - occurs while at rest at night, severe pain - medicine works
variant (Printzmetal's)
80
can be more severe and last longer than other types | -medicine may not relive this type of pain
microvascular
81
aka heart disease; - coronary arteries supply heart with nutrients an oxygen by circulating blood - these arteries can become damaged or diseased - damage may be related to atherosclerosis; hardening of arteries or buildup of plaque - may cause heart attacks, ischemic strokes, heart failures, arrhythmias
Coronary artery disease
82
to heart muscle due to lack of blood to heart - occur as a result of coronary heart disease - plaque can rupture, causing a blood clot to form - large enough clot can completely block coronary artery - if not treated quickly, affected portion of heart muscles begin to die
Heart attacks
83
heart can beat too fast or too slow or irregular rhythm too fast= tachycardia too slow= bradycardia Symptoms: feeling faint, light-headed, shortness of breath, chest pain, palpations causes heart disease, infections/fever, physical/emotional stress, drugs Two Types: 1. ventricular: starts from heart’s ventricles 2. Supraventricular: starts outside or above the ventricles (atrial fibrillation) Atrial Fibrillation (AF or AFib) “fibrillate” = contract very fast and irregularly AFiB can increase the risk of forming blood clots leading to strokes, or heart failure because of blood pools in the atrium -cause chest pain or heart failure
Heart arrythmias
84
Heart suddenly and unexpectedly stops beating - an electrical malfunction of the heart - results in sudden cardiac death - not the same as a heart attack: - HA occurs if blood flow to the heart muscle is blocked - during HA, heart doesn’t stop beating - SCA may occur after heart attack
Sudden Cardiac Arrest (SCA)
85
birth defects, age-related changes, infections, or other conditions cause one or more heart valves to not open fully or close; blood leaks back into the heart -congenital heart valve disease: valves don’t form properly many people do not have symptoms until older 3 types: -regurgitation: (backflow) occurs if a valve doesn’t close tightly -stenosis occurs if the flaps of a valve thicken, stiffen or fuse together -atresia occurs if a heart valve lacks an opening for blood to pass through
Heart Valve Disease-
86
heart failure; form of cardiovascular disease that results in decreased ability of the heart to pump blood forward or the ability to fill the heart with blood in a cyclical manner - if heart fails to pump blood out of arteries to vital organs, those organs will be damaged - fluid will start to collect in the lungs= shortness of breath & loss of good air exchange that leads to tissue damage
Congestive heart Failure
87
Electrocardiogram (EKG/ECG) -measures electrical activity of the heartbeat, with each beat an electrical “wave” travels through the heart Holter Monitoring or Ambulatory ECG or Ambulatory EKG -documents and describes abnormal electrical activity in the heart during daily activities to help doctors determine the condition of the heart Chest X-Ray -determines whether the heart is enlarged or if fluid is accumulating in the lungs as a result of the heart attack Echocardiogram (echo) -device place on the chest that uses ultrasound to produce images of heart Cardiac tomography (CT/CAT scan) -diagnostic-imaging tests to gather images of the heart -creates 3D images that can show blockages caused by calcium deposits in coronary arteries Exercise Stress Test -treadmill test to monitor heart function while walking on a treadmill -HR, breathing, BP and how tired you become when exercising Cardiac Catheterization
Heart Disease Diagnostics
88
AED- what is it used for?
Automated defibrillator- portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation -delivers electrical shock to the heart to restore its normal rhythm
89
percutaneous coronary intervention -is a procedure used to open clogged heart arteries by inserting and inflating a tiny balloon to the clogged artery to widen the artery Often combined with permanent placement of a small wire mesh tube (stent) to help prop artery open and decrease the chance of it narrowing again
Coronary Angioplasty
90
Open chest surgical procedure- one or more blocked coronary arteries are bypassed by a blood vessel graft -restores blood flow to the heart
Coronary Artery Bypass Surgery (CABS)
91
Generally, once it’s determined that a diseased heart valve needs treatment, the available choices are valve repair or valve replacement: - valve repair preserves the patient’s valve and leaflets - repair is most often possible for mitral valve regurgitation and tricuspid valve regurgitation
Heart Valve Disease Treatment
