EO 009 - Lower MSK Flashcards
(45 cards)
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
What are some pertinent findings for meniscal tears?
ppt EO 009.03(b)
- Locking of knee
- Popping, clicking, snapping
- Instability with activity
- Tenderness in anterior joint space after activity
- Age/degenerative disease
- Trauma
Slide 11
What is varus stress?
https://my.clevelandclinic.org/health/diagnostics/25145-valgus-and-varus-stress-tests
Force pushing away from the center of the bodybody
Related to slide 14 of ppt EO 009.03(b)
What is valgus stress?
https://my.clevelandclinic.org/health/diagnostics/25145-valgus-and-varus-stress-tests
Force pushing into the midline or center of the body.
Related to slide 14 of ppt EO 009.03(b)
Which ligament is affected by valgus stress?
ppt EO 009.03(b)
The medial collateral ligament. Also most commonly injured.
Slide 14
Which ligament is affected by varus stress?
ppt EO 009.03(b)
Lateral collateral ligament.
Slide 14
What is the “unhappy triad” injury of the knee?
ppt EO 009.03(b)
An injury involving the medial collateral ligament (MCL), anterior cruciate ligament (ACL), and medial meniscus.
