Q

open fractures Tx ?

A

antibiotics within 1 hour
First-generation cephalosporins
ADD Gram-negative coverage large degloving injuries or wounds that communicate with the bowel
Small lacerations irrigated and closed
larger wounds may require operative exploration
packing open wound performed before applying binder

Q

extremity traction ?

A

realigning anatomy
decreasing bleeding
reducing pain
beneficial for definitive treatment
skeletal traction pins placed in the distal femur, proximal or distal tibia, or calcaneus.

Q

What alternatives exist if skeletal traction is not possible?

A

manual traction during binder application, internal rotation of the extremities, and taping the toes together.

Q

risks of continued use of a CPAS or binder beyond 24 hours

A

obscure femoral access, impede abdominal access, and cause skin necrosis

Q

How should removal of the CPAS or binder be performed

A

ideally in the ICU, with the binder removed slowly and left in place beneath the patient for rapid reapplication if needed.(Hypotension)

Q

When is pelvic angiography indicated

A

persistent arterial bleeding
unresponsive to resuscitative efforts
have a binder or external fixation in place
and do not require surgical hemorrhage control.

Q

hen should pelvic packing be considered

when retroperitoneal hemorrhage is suspected
patient is unresponsive to binder
and primary resuscitation with intravenous fluids and blood.

Q

Why is understanding the pathoanatomy of pelvic hemorrhage important for pelvic packing?

A

because retroperitoneal veins in the space of Retzius and retroperitoneum are responsible for much of the pelvic hemorrhage

Q

How is pelvic packing performed?

A

Three pads are forcibly packed on each side: along the pelvic brim, into the true pelvis, and posteriorly near the sacroiliac joint.

pelvis must be stabilized with a binder or an external fixator

Q

What identifies an APC2 injury, and what structures are disrupted?

A

> 2.5 cm of anterior symphysial widening

Q

What are the characteristics of an APC3 injury?

A

rupture of all anterior and posterior pelvic ligaments, gross instability of one or both hemipelves

Q

What are the characteristics of an LC1 injury?

A

the sacral foramen or ala
anterior fractures of the superior and inferior rami
internal rotation of one hemipelvis.
common in the elderly after a fall from standing.

17
Q

What are the characteristics of an LC2 injury?

A

posterior fractures through the iliac wing
anterior fractures of the rami.

18
Q

LC3 injury, and why is it known as the “wind-swept” pelvis?

A

internal rotation of one hemipelvis
external (AP-type) rotation of the opposite hemipelvis, creating the “wind-swept” appearance.
These injuries have the greatest instability.

19
Q

How common is distal displacement in VS fractures,

A

very rare but is associated with significant nerve injury

20
Q

proximal vertical displacement in VS fractures?

A

vascular injury and soft tissue damage to the iliolumbar ligaments
anterior and posterior sacroiliac ligaments
anterior pelvic ligaments

21
Q

How is pelvic hemorrhage managed in patients with VS fractures?

A

Longitudinal traction on the shortened limb and binder application

22
Q

When does external fixation have a significant role

A

after 24 hours, typically when the patient can be transported to the operating room

23
Q

What is the preferred method of external fixation for pelvic fractures?

A

supra-acetabular two-pin external fixation

24
Q

When is external fixation preferred over internal fixation

A

when prior surgery or radiation complicates anterior open approaches
when there is an open fracture or gross contamination
or when other surgical incisions make standard approaches difficult.
