Pre-Lab Saurderland Flashcards
Anteriorposterior compresssion of pelvis
pelvic fracture
Fracture of all four pubic rami
straddle injury
If you fracture pubic rami what will you be fracturing?
ischiopubic ramus and superior pubic ramus
Forces transmitted from lower limbs to pelvis (fall on feet) can result in a fracture in area of (blank)
Acetablum (head of femur dislocates and pushes into the joint resulting in fracture)
Pelvic fracture can result in what?
trauma to bladder
What can a fracture of inferior pubic ramus cause?
injury to deep perineal space in UG triangle and damage to urethra/vagina
What can a fracture of pubic rami cause?
injury to urethra/ torn urethra/ bladder and prostate separates, extravasion of urine, retroperitoneal hemorrhage
anal glands will drain into (blank)
anal crypts
What are these; blind internal (sinus) complete internal external (intrasphincteric and transsphincteric) branching (complex) horshoes
types of anorectal fisulae
What are these:
- ***Supralevator
- retrorectal,
- pelvirectal
- submucous
- **Intfralevator;
- ishiorectal.
- intermuscular
- subcutaneous
- Cutaneous
Location of anorectal abscesses
What do you call it when in abscess when one side spreads to the other side?
perineal horseshoe abscess (usually posterior)
When you are starved, what are the last fat reserves that will be used?
ischioanal fossa
What happens if you lose the fat of the ischioanal fossa?
you will have rectal prolapse
What is a procidentia?
when all layers of the rectum prolapse
What does the Internal rectal (hemorrhoidal) plexus
drain to?
To tributaries of the superior rectal vein
to inferior mesenteric vein
to portal vein
What does the external rectal (hemorrhoidal) plexus drain to?
To inferior rectal vein to internal pudendal vein to internal iliac vein to common iliac vein to inferior vena cava
(blank) are prolapses of rectal mucosa,
Resulting from a breakdown of the muscularis mucosae. These are not painful.
Internal Hemorrhoids
(blank) that prolapse into or through
the anal canal are often compressed by the
contracted sphincter ani, impeding the blood flow. As a result, they tend to strangulate and ulcerate.”
Internal Hemorrhoids
(blank) are thromboses (blood clots) in the veins of the external rectal venous plexus.
External hemorrhoids
(blank) are covered by skin. The skin over the
these is painful because it is supplied by somatic sensory fibers of the inferior anal nerves .
external hemorrhoids
