1

What are some of the main branches of the Sacral Plexus?

Sciatic Nerve
Superior Gluteal Nerve
Inferior Gluteal Nerve
Pudendal Nerve (Supplies Perineum)

2

What are some of the main branches of the Sacral Plexus?

Sciatic Nerve
Superior Gluteal Nerve
Inferior Gluteal Nerve
Pudendal Nerve:
-Supplies Perineum

3

The Superior Gluteal Nerve of the Sacral Plexus innervates what?

Gluteus Minimus
Gluteus Medius
Tensor Fasciae Latae

4

A Characteristic motor loss resulting in weakened abduction of thigh by the gluteus medius, disabling gluteus medius limp, and gluteal gait (compensatory list of the body to weakened gluteal side, is seen with injury to what nerve?

Superior Gluteal Nerve Injury

5

Weight supported on both feet with no injury will have what positioning of the pelvis?

Pelvis is evenly supported and does not sag

6

When no injury is to the superior gluteal nerve is present if weight is borne by one foot what will the muscles of the lower extremity do?

Muscles on the same side will hold the pelvis so it will not sag

7

What will occur if the gluteus medius and gluteus minimus are inactive due to superior gluteal nerve injury when weight is borne by one foot?

Pelvis fall on the side of the raised limb
-Steady action is lost

8

What is a positive Trendelenburg sign?

Hip drop on one side (raised leg) or during walking

9

The Gluteus Maximus is innervated by what nerve of the sacral plexus?

Inferior Gluteal Nerve

10

The Piriformis Muscle is innervated by what nerve of the Sacral Plexus?

Nerve to Piriformis

11

The Sural Nerve is a sensory nerve in the calf region is made up of collateral branches of what two nerves?

Tibial Nerve
Common Fibular Nerve

12

The Sural Nerve is a sensory nerve in the calf region is made up of collateral branches of what two nerves?

Tibial Nerve
Common Fibular Nerve

13

The Tibial Nerve, branch of the Sciatic Nerve, furthers divides into what?

Medial Plantar Nerve
Lateral Plantar Nerve

14

The Common Fibular Nerve (Common Peroneal), branch of the Sciatic Nerve, furthers divides into what?

Deep Fibular Nerve
Superficial Fibular Nerve

15

The Tibial Nerve innervates what?

-Gastrocnemius
-Plantaris
-Soleus
-Popliteus
-Tibialis Posterior
-Flexor Digitorum Longus
-Flexor Hallucis Longus
FOOT:
-Medial Plantar
-Lateral Plantar

16

What branch of the Tibial Nerve innervates the Abductor Hallucis, Flexor Digitorum Brevis, Flexor Hallucis Muscles and First Lumbrical Muscles?

Medial Plantar Nerve

17

The Lateral Plantar Nerve, a branch of the Tibial Nerve innervates what structures?

-Plantar Muscles of Foot (Remaining)
-Skin over Lateral 1/3 of Plantar Surface of Foot

18

The Tibialis Anterior, Extensor Hallucis Longus, Fibularis Tertius, Extensor Digitorum Longus, Extensor Digitorum Brevis muscles, and skin on adjacent sides of great and second toe are innervated by what nerve?

Deep Fibular (Branch of Common Fibular)

19

The Tibialis Anterior, Extensor Hallucis Longus, Fibularis Tertius, Extensor Digitorum Longus, Extensor Digitorum Brevis muscles, and skin on adjacent sides of great and second toe are innervated by what nerve?

Deep Fibular (Branch of Common Fibular)

20

Where does the Sciatic Nerve exit the pelvic cavity?

Greater Sciatic Foramen below the Piriformis

21

What occurs in about 10% of the population in relation to the sciatic nerve?

Nerve passes through Piriformis (Conditions which cause the muscle to shorted and contract increase nerve compression)

22

What occurs in about 10% of the population in relation to the sciatic nerve?

Nerve passes through Piriformis (Conditions which cause the muscle to shorted and contract increase nerve compression)

23

Piriformis Syndrome can have what symptoms?

Buttock pain
Sciatic Symptoms in leg
-Sciatic component of pain in the leg can be in dermatome of any nerves that comprise the sciatic nerve (L4,L5,S1, S2)

24

What is the treatment for Piriformis Syndrome?

Release of contracted piriformis muscle w/combination of exercises, acupuncture, trigger point injections
-Surgery (Release from attachment to superior part of greater trochanter of femur)

25

Why is the gluteal region a common site for intramuscular injections? What has to be considered about this area?

-Muscles are thick and large (Good Absorption)
-Area of Sciatic Nerve

26

Intramuscular injections in the gluteal region should be made in what area?

Superior to line extending from Posterior Superior Iliac Spine to Superior Border of Greater Trochanter

27
