2

VPR L4-5

7

Posterior divisions of L4-S1

8

Posterior divisions of VPR L5-S2

9

14

What are symptoms of a fracture to the femoral neck

Limb laterally rotated and shortened

15

What is a possible result of a fracture to the femoral neck

Proximal avascular necrosis due to disruption of blood supply from medial femoral circumflex artery

16

What is the locational difference between a intertrochanteric fracture and a fracture of the femoral neck

Intertrochanteric: extracapsular
Femoral neck: intracapsular
Location and availability of blood supply due to location dramatically changes healing time

17

What is the result of a posterior dislocation of the hip joint

Possible injury to sciatic nerve:
paralysis of hamstrings and everything distal to knee
Loss of sensation over postolateral leg and most of foot

18

What is the result of a anterior dislocation of the hip joint

My damage femoral nerve:
Paralysis of sartorius and quads
Loss of sensation to medial leg and foot

19

What is the result of an injury to the superior gluteal nerve

Gluteal Gait: weakened ABD and MR of thigh listing of body and limb becomes "too long" and patient is unable to walk with foot clearing the ground
Positive Trendelenburg test

20

What is the result of an injury to the sciatic n in the gluteal region

Usually damaged on the medial side
Compression: pain radiating from buttock down leg
Complete lesion: leg basically becomes useless, only able to use muscles supplied by the saphenous n

21

What is an intermittent claudication

Blockage of femoral, popliteal, or posterior tibial artery
Causes ischemia to muscles during exercise

22

What is the result of an injury to the femoral nerve

Weakened flexion of thigh, loss of leg extension, loss of sensation to medial thigh
Difficulty walking up uphill or stairs

23

Where are femoral hernias most likely to occur

Protrudes through femoral ring into the femoral canal compressing everything

24

What are symptoms of a torn hamstring

Extreme pain, bruising and tearing of muscle tissue, usually the semimembronosus

25

What likely will be injured with a blow to the lateral side of an extended knee

The "unhappy triad"
Ruptured TCL
concomitant tearing of medial meniscus
Tearing of ACL

26

Which direction does the tibia slide after a tear of the ACL

Tibia is free to slide anteriorly under fixed femur

27

Which direction does the tibia move with a PCL tear.

Tibia is free to slide posterior under fixed femur

28

What is Q-angle in the knee

Femur diagonal in thigh, while tibia is almost vertical in leg

29

What is genu varum

Bowleg
Small q angle

30

What is genu valgum

Knock knee
Large q angle
