Answer 1

•Left alone if they are closed (no overlying
wound)

Subdural with no deviation rx

Answer 3

If there is no deviation, therapy is centered on preventing further damage from ↑ ICP

up to 48 hours after chest trauma
deteriorating blood gases
“white out” lungs on chest x-ray

Answer 4

Question 5

Flail chest/ pulm contusion rx

Answer 5

• sensitive to fluid overload–> fluid restriction and diuretics
• blood gases have to be monitored
• may need respirator (chest tubes might help here)

also ps: To get a flail chest big trauma is required, thus traumatic transection of the aorta must be actively
sought.

Answer 6

suspected in sternal fractures.
EKG monitoring will detect it.
Troponins are quite specific and should be ordered

rx focused on the complications (arrhythmias)

If i coagulopathy, hypothermia, and acidosis during an operation, what do you do?

Answer 7

laparotomy promptly terminated, with packing of bleeding surfaces and temporary closure

Question 8

second postoperative day
develops distention, retention sutures cutting through the tissues, hypoxia secondary to inability to breathe, and renal failure

Answer 8

long surgery–> abdominal swelling

may even show up at closing time

developmental dysplasia of hip rx

Answer 18

abduction splinting with Pavlik harness for about 6 months

Question 19

Legg-Calvé-Perthes disease is?

Answer 19

avascular necrosis of the capital femoral epiphysis

occurs ~ 6 yo

insidious development of limping, decreased hip motion, and hip/knee pain

Question 20

Slipped capital femoral epiphysis is an emergency, rx is?

Answer 20

surgical treatment pins the femoral head back in place.

Question 21

Femoral neck fractures rx

Answer 21

Faster healing and earlier mobilization can be achieved by replacing the femoral head with a prosthesis.

Question 22

Intertrochanteric fractures

Answer 22

less likely –> avascular necrosis

reated with open reduction and internal fixation.

↑ risk of DVT/PE, thus post-op anticoagulation is
recommended

Question 23

describe catching and locking that limit knee

motion, and a “click” when the knee is forcefully extended

Answer 23

Meniscal tears

rx: open repair

Question 24

Answer 27

Mallet finger splinting is usually the first line of treatment.

Question 28

a squamous cell carcinoma of the skin developing in a | chronic leg ulcer.

Answer 28

Marjolin ulcer A dirty-looking, deeper ulcer develops at the site, with heaped up tissue growth around the edges. Biopsy is diagnostic. Wide local excision and skin grafting are done.

Answer 29

``` Fluid/ electrolyte replacement nutritional support (preferably elemental diets delivered beyond the fistula) compulsive protection of the abdominal wall ``` let nature heal itself

Answer 31

Acute edematous pancreatitis

Question 32

____________ pancreatitis is a much more deadly disease (vs edema).

Answer 32

Acute hemorrhagic pancreatitis starts as the edematous form, early laboratory clue is dropping hematocrit needs icu care daily CT scans are recommended to look for abscess

Question 33

Necrosectomy

Answer 33

debriding the dead pancreatic tissue Patients do far better by waiting at least 4 weeks before debriding

Question 34

late sequela of acute pancreatitis or of | pancreatic (upper abdominal) trauma

Answer 34

Pancreatic pseudocyst -collection of pancreatic juice outside the pancreatic ducts (most commonly in the lesser sac) Bigger (>6 cm) or older cysts (>6 wk) are more likely to rupture or bleed, and they need to be treated. Treatment involves drainage of the cyst.

Question 35

Acute hemorrhagic pancreatitis

Answer 35

starts as the edematous form, early laboratory clue is dropping hematocrit needs icu care daily CT scans are recommended to look for abscess

Question 36

Pancreatic pseudocyst, when to drain

Answer 37

Chronic pancreatitis lots of episodes of pancreatitis (usually alcoholic) eventually develop calcified burned out pancreas,

Question 38

Answer 38

Intraductal papilloma Mammogram is needed to identify other potential lesions, but it will not show the papilloma (they are tiny). Galactogram may be diagnostic and guides surgical resection.

Answer 39

lumpectomy + axillary sampling + post-op radiation (small tumor, far from nipple) or modified radical mastectomy + axillary sampling. ***Adjuvant systemic therapy should follow surgery in virtually all patients- Chemotherapy is used in most cases**
