Question 1

Question
A subtrochanteric fracture of the hip involves a fracture between the greater and lesser trochanter.
Answer
  • True
  • False

Question 2

Question
Total hip replacements are usually called for hip fractures because the acetabulum does not have a redundant blood supply resulting in avascular necrosis.
Answer
  • True
  • False

Question 3

Question
AVN stands for [blank_start]avascular necrosis[blank_end].
Answer
  • avascular necrosis

Question 4

Question
FAI stands for [blank_start]femoroacetabular impingement[blank_end]. A bump on the femur is a [blank_start]cam[blank_end]. Extra growth that extends the rim of the acetabulum is a [blank_start]pincer[blank_end].
Answer
  • femoroacetabular impingement
  • cam
  • pincer

Question 5

Question
Treatment for a FAI is typically a THR.
Answer
  • True
  • False

Question 6

Question
An acetabular labral tear usually results in dislocation of the hip.
Answer
  • True
  • False

Question 7

Question
Which of these is true about trochanteric bursitis?
Answer
  • involves the greater and lesser trochanter
  • is a macro trauma disorder
  • may occur with a little bit of hip drop
  • occurs due to compressing and rubbing of bursa and associated tendons

Question 8

Question
Osteoarthritis at the hip occurs due to narrowing space between acetabulum and femoral head. Resultant grinding rubs away joint cartilage and usually requires a THR.
Answer
  • True
  • False

Question 9

Question
Which of these is not a precaution for THR posterolateral approach?
Answer
  • external rotation
  • internal rotation
  • adduction
  • more than 90 flexion

Question 10

Question
Which of these is true about ACL rupture?
Answer
  • highest incidence is in women older than 50s
  • bone tendon bone reconstruction of ACL uses central 3rd of achilles tendon
  • occurs due to rapid acceleration during sport activities
  • more common in adolescent females

Question 11

Question
Which of these is true about MCL rupture?
Answer
  • occurs with LCL and medial meniscus tear
  • force required for rupture is a varus force
  • the medial meniscus is highly vascularized and often will heal on its own
  • the MCL is attached to the ACL and medial meniscus

Question 12

Question
It is rare for an LCL to be due to microtrauma.
Answer
  • True
  • False

Question 13

Question
PCL tear occurs frequently in car accidents when tibia slams into dashboard and femur travels backwards on tibia.
Answer
  • True
  • False

Question 14

Question
Which of these is true about menisci of knee?
Answer
  • a bucket handle tear happens in the lateral edge of the meniscus
  • the most superficial zone of the meniscus is partially vascularized
  • damage to medial part of meniscus will probably not heal
  • all tears to the meniscus require knee replacements

Question 15

Question
Patellofemoral pain syndrome...
Answer
  • occurs due to excessive wearing of infrapatellar tendon
  • occurs due to excessive wearing of underside of patella on femoral condyle
  • is usually corrected with surgery
  • can be relieved if the patella is retrained to move laterally.

Question 16

Question
When the patella dislocated it almost always dislocates [blank_start]laterally[blank_end].
Answer
  • laterally
  • medially

Question 17

Question
Patellar tendonitis occurs when there is too much stress coming on to the ligament of the knee.
Answer
  • True
  • False

Question 18

Question
Pes anserine bursitis most often occurs in older men and involves the lateral knee.
Answer
  • True
  • False

Question 19

Question
Inversion of the ankle usually involves injury to the [blank_start]anterior talofibular ligament[blank_end].
Answer
  • anterior talofibular ligament

Question 20

Question
[blank_start]Posterior tibialis tendonitis[blank_end] is an over [blank_start]pronation[blank_end] injury in which the posterior tibialis is used to maintain the arch of the foot rather than having proper alignment of tarsal bones.
Answer
  • Posterior tibialis tendonitis
  • pronation

Question 21

Question
Plantar fascitis is heel pain with point tenderness at calcaneal tubercle.
Answer
  • True
  • False

Question 22

Question

Answer

  • pain occurs during rest
  • metatarsal cookie can relieve pain
  • pain occurs during weight bearing and at rest

Question 23

Question
Which of these is true about toe deformities?
Answer
  • flexion at MTPJ, extension at PIP and flexion at DIP joint is a hammer toe
  • hyperextension of MTP, flexion at DIP and PIP is claw toe
  • extension at MTPJ, PIP and DIP is hammer toe
  • hyperextension of MTPJ and DIP, with PIP flexion is mallet toe

Question 24

Question
Which of these is not true about pes planus?
Answer
  • longitudinal arch flattens out
  • posterior tibialis tendon may become enlarged and thickened
  • sole of foot becomes lengthened
  • cuboid makes full contact with floor

Question 25

Question
Hallux abducto valgus is due to excessive lateral drift of 1st ray due to an external rotation of foot.
Answer
  • True
  • False

Question 26

Question
Which of these is true about pes varus?
Answer
  • the navicular make contact with the floor
  • often due to improper foot wear
  • occurs due to lots of flexion of MTPJ
  • normal flattening of arch of foot during walking is restricted

Question 27

Question
ATFL tear occurs due to an inversion and dorsiflexion injury to the ankle.
Answer
  • True
  • False

Question 28

Question
Aside from an ATFL tear in the ankle, the [blank_start]posterior talofibular[blank_end] ligament or [blank_start]calcaneofibular[blank_end] ligament may tear.
Answer
  • posterior talofibular
  • calcaneofibular
