Q

What is the pectineal ligament?

A

The continuation of the lacunar lig. that proceeds on the pectineal crest of the superior pubic ramus, which blends with the other connective tissue that turns back into the inguinal lig. forming the iliopectineal arch.

18
Q

What are the two parts of the obturator foramen?

A

Obturator membrane, which almost covers the the entire foramen, and the obturator canal (superiorly)

19
Q

Obturator canal is formed by the?

A

Inferior surface of the superior pubic ramus, and upper edge (sometimes very sharp/ ossified) of the obturator membrane

20
Q

What runs through the obturator canal?

A

Neurovascular bundle: obturator nerve/ artery and vein

21
Q

Attachment of Sacrospinous lig.

A

Anterior to sacrotuberous lig.
- between the apex of ischial spine and lateral margin of lower sacrum.
Forms greater and lesser sciatic foramina

22
Q

Attachment of sacrotuberous lig.

A
  • SPIS
  • Post. sacroiliac lig.
  • Lower lateral sacral crest
  • Lateral margins of lower sacrum and upper coccyx
23
Q

Iliolumbar lig. 2 parts?

A

Sup. part- attaches to iliac crest lateral to attachment of QL
Ant. part- attach and enhance fibrous capsule of the sacroiliac joint

24
Q 
Slipped Capital Femoral Epiphysis is?
What happens?
Age?
Causes?
Symptoms?
A
  • Weakened epiphyseal growth plate
  • Femoral head may slip away from femoral neck
  • Adolescents 10-17 yrs old (male 2-3x more common)
  • Acute trauma or rep. micro trauma
  • Can present as knee pain
25
Q

Describe patella

A

Sesamoid bone within quadriceps tendon. increases leverage or quadriceps Femoris m. by making it act at a greater angle.

26
Q

What is the purpose of Gerdy’s anterolateral tibial tubercle( iliotibial tract) ?

A

Serves for the attachment of the IT band

27
Q

What is a bumper fracture?

Freiberg Disease

32
Q

An accessory ossicle that is a secondary ossification center of talus that fails to unite with the body of talus

A

Os Trigonum

an additional piece of bone

33
Q

What nerves supply L1? Lateral to medial

A

Lateral cutaneous br. of iliohypogastric, lateral cutaneous br. of subcostal, femoral br. of genitofemoral, and ilioinguinal n.
