EO 009 - Lower MSK Flashcards
What is the inguinal triangle?
ppt EO 009.03 (a)
A structure bordered by the inguinal ligament, sartorius muscle, and adductor longus.
Slide 5
What does the inguinal triangle contain?
ppt EO 009.03 (a)
The femoral nerve, artery, vein, as well as the great saphenous and external pudendal vein.
Slide 5
What deep, non-palpable muscle runs through and under the inguinal ligament?
ppt EO 009.03 (a)
Psoas major
Slide 6
What criteria constitutes a pelvic fracture?
ppt EO 009.03 (a)
One of the following:
1. A break in the pelvic ring
2. # of a bone without a break in the ring
3. Acetabular # (articulating region of pelvis -> femur)
Slide 9, look at visual for #3
What is the difference between stable and unstable # of pelvis?
ppt EO 009.03 (a)
A stable #is a single break in the pelvic ring.
An unstable # is two breaks in the pelvic ring, risking displacement.
Slide 10
What are the three pelvic # patterns?
ppt EO 009.03 (a)
- Anterior-posterior compression (APC)
- Lateral compression (LC)
- Vertical shear (VS)
Slide 11, see for visuals
Which sort of pelvic fracture is typically commonly seen in conjunction with multiple lower MSK fractures?
ppt EO 009.03 (a)
Acetabular #s
Slide 12. Typically secondary to MVC
What is a hip #?
ppt EO 009.03 (a)
A fracture of the femur in or near the hip joint.
Slide 16
What are the four classifications of hip fractures?
ppt EO 009.03 (a)
- Femoral head + neck
- Trochanteric
- Intertrochanteric
- Subtrochanteric
Slide 16, does no elaborate on each classification.
Why is hip dislocation considered a true orthopedic emergency, and what is the time frame for surgery?
ppt EO 009.03 (a)
Delays in reduction increase incidences of avascular necrosis, should be seen within 6 hours.
Slide 20.
What is the technical name for bursitis in the hip?
ppt EO 009.03(a)
Trochanteric bursitis
Slide 22
What are some tx options for trochanteric bursitis?
ppt EO 009.03(a)
- Rest/MELs
- NSAIDs/analgesics
- Heat/cooling
For MO:
1. Corticosteroid
2. ABx (septic)
Slide 23
Which movements cause medial knee injuries?
ppt EO 009.03(b)
Abduction, flexion, and internal rotation of femur.
Slide 6
Which movements cause lateral injuries of the knee?
Adduction, flexion, and external rotation of the femur
Slide 6
What causes meniscal injuries?
ppt EO 009.03(b)
Cutting, squatting, or twisting movements.
(rotary + extension/flexion)
Slide 7
List the types of meniscus tears.
- Longitudinal
- Bucket and handle (also longitudinal)
- Flap
- Transverse
- Torn horn
Slide 7, visuals
Which type of meniscus tear is most common?
ppt EO 009.03(b)
Bucket handle tear
Slide does say longitudinal, but specifies horn-to-horn tears
Slide 8
What is the triad of symptoms for meniscal tears?
ppt EO 009.03(b)
- Joint line pain on palp (75%)
- Joint effusion
- Locking on flex/extension
Slide 9. Example of effusion on slide 10
