Q

This is caused by forceful compression of C1 from top of head which causes lateral masses compression between the occipital condyles along with fracture of anterior or posterior arches (diving accidents, roll over car accidents). The rupturing of the transverse ligament is characteristic of this as well.

A

Saphenous cutdown

21

Handyman wearing a tool belt has numbness and tinging in his lower extremity. What nerve is being impeded? This also occurs in girls who wear skinny jeans.

A

Lateral femoral cutaneous nerve

22
Q

Contusion (bursted capillaries/bruise) of the iliac crest at the anterior part, usually occurring within contact sports

This disease is abnormal kyphosis. It can cause thoracic disc herniation.

A

Scheuerman’s disease

28
Q

Horizontal blow/trauma to the head or neck creates what fracture?

A

Fracture of the Dens

29
Q

Turning head rapidly can cause dizziness and confusion. This is because of what?

A

Keeping head turned for long periods of time can cause dizziness due to _____ ____. This is called _____ _____ Syndrome

A

vertebral artery impingement

Bow Hunter’s Syndrome

Q

What does a femoral hernia go through?

A

Femoral ring

35
Q

What does an indirect inguinal hernia go through?

A

Deep inguinal ring
