Q

what ligament attaches the femoral head to the acetabulum?

A

ligamentum teres

17
Q

what is the treatment for gluteus tendon avulsion?

A

early surgical repair

18
Q

what are the three subtypes of FAI?

A

CAM, pincer and mixed

19
Q

when does the external iliac artery become the femoral artery?

A

after crossing underneath the inguinal ligament

20
Q

which condition causes misshapen femoral head, shallow acetabulum, excessive anteversion of the acetabulum and proximal femur?

21
Q

what is the ultimate treatment for FAI?

A

surgery (including labral repair component)

22
Q

describe the center edge angle of Wiberg on a radiograph when assessing hip dysplasia?

A

vertical line drawn from the center of the femoral head and a line from the center of the femoral head to the lateral edge of the acetabulum

23
Q

what center edge angle of Wiberg measurement is considered dysplastic?

A

20 degrees or less

24
Q

describe the relative difference in pain sitting/standing between FAI and DDH, which can help to differentiate these conditions

A

DDH - more pain with standing
FAI - more pain with sitting

25
dysplasia of the hip joint could be in either or both of what two directions?
lateral and anterior
26
t/f in a case of DDH, in patients with degenerative cartilage, surgery to preserve the hip joint is contraindicated
true
27
ischiogluteal bursitis is inflammation in the bursa found between what two structures?
gluteus maximus and ischial tuberosity
28
how would you differentiate ischial bursitis from hamstring injury on physical exam?
absence of pain with stretching - indicative of bursitis
29
80% of acute hamstring injuries occur in what muscle?
long head biceps femoris
30
for how long minimum should you allow for recovery for a grade 1 / 2 hamstring injury?
4 weeks
31
what are the three main osseous areas of the hip where avulsion can occur in athletes?
AIIS (rectus) , ASIS (sartorius) and ischial tuberosity (hamstring)
32
the insertion of what two adductor muscles can be related to medial femoral shaft stress fractures?
adductor longus and brevis
33
a patient is found to have osteoid osteoma of the femur. what is the typical treatment?
radiofrequency ablation
34
what type of fracture is associated with chronic bisphosphonate use?
atypical femur fracture
35
what percentage of cases of atypical femur fracture have bilateral occurrence?
50%
36
a patient with known breast cancer has a positive halo sign (bright) on T2 weighted images of the hip. what is the most likely cause of this radiographic finding?
metastases
37
where does the gluteus maximus attach?
linea aspera of the femur
