Peroneal arise at
L4 – L5

Peroneal innervates =
peroneus longus,
peroneus brevis,
biceps femoris (short head)
most common cause of peroneal nerve palsy
Compression of the fibular head
Most commonly involved vein in DVT:
anterior tibial
posterior tibial vein
fibular vein
the deep and superficial venous drainage of the lower limb.

Both deep and superficial veins terminate in the
femoral vein.
Right ovarian vein drains into the
vena cava
ectopic pregnancy of the isthmus of the left tube is noted to have ruptured, leading to hemorrhage. The blood noted arises principally from
Uterine and ovarian arteries
- Brachial plexus injury, probably Erb palsy
- Stretching of the upper brachial plexus during delivery

- Stretching of nerve roots =
C5 and C6 by abnormal increase in the angle between the neck and shoulder
muscles are primarily responsible for abduction of the arm at the shoulder?
Deltoid
supraspinatus
A 22-year-old man is brought into the emergency department with a knife injury to the axilla. The physician suspects injury to the lower brachial plexus. Which of the following nerves is most likely to be affected?
Ulnar
examining an axial (cross-section) magnetic resonance imaging (MRI) scan of the wrist and have identified the carpal tunnel. Which of the following is the structure that forms the anterior wall of
the tunnel?
Flexor retinaculum
where the median nerve is located just as it is about to enter the tunnel. Where is the median nerve located?
Just medial to the flexor carpi radialis tendon
If the median nerve were severed in an industrial accident at the wrist, which of the following muscles would still retain their function?
Lumbricals of the ring and little fingers
The radial nerve is a nerve that runs down the
underside of the arm and controls movement inthe =

The radial nerve is also responsible for =
triceps


extending the wrist and fingers, and controls sensation in a portion of the hand
 Origination of radial nerve
Origin
Radial nerve originates from the posterior cord of the brachial plexus (C5-T1)
behind axillary artery
Atheroschlerosis
Most important risk factor=
Hypertension causing injury to tunica intima Risk factors
 Foam cells =
migrated macrophage
] A patient with a severe tear of the medial collateral ligament of the wrist would likely display which of the following increased wrist movements?
Abduction
Which of the following structures transmits the force from the radius to the ulna?
Interosseous membrane
- Glenohumeral joint dislocation (shoulder dislocation)
1. What is the most likely nerve injured?
- Axillary nerve
 Primary stability = rotator cuff muscles
Most commonly ruptured tendon =
supraspinatus muscle
the only bony articulation between the upper limb and the trunk.
Sternoclavicular
MC Hip Fracture =
 Fracture in fibular neck
 Hip joint is surrounded by joint capsule
- Iliofemoral ligament
- Ichiofemoral ligament
 Hip joint Arterial supply is by
medial circumflex artery
Lateral Circumflex A

Fed by
(profunda femoris),

also the Obturator
posterior dislocation of the hip, which of the following ligamentous structures would be torn?
Ischiofemoral ligament
A patient with the hip dislocation is also exhibiting weakness of extension of the thigh at the hip. This would indicate possible damage to which of the following?
Tibial portion of the sciatic nerve
- Superior vena cava (SVC) syndrome
- Bronchogenic lung cancer

what are the structures involved
SVC
trachea
right mainstem bronchus
 Superior Vena Cava Syndrome
Nerve involved on the R side from a tumor compression=
Recurrent Laryngeal Nerve
ductol or lobular CA
come from =
Breast epithelial lining
most common breast Ca type =
Ductal Carcinoma
A patient has sustained lower limb trauma that has damaged the posterior tibial artery. Therefore, you will be concerned about the blood supply to which of the following?
medial plantar arteries
lateral plantar arteries.
plantar arch arteries

FEEDING ALL OF THE PLANTAR SIDE OF THE METATARSALS & PHALANGES

Posterior compartment of the leg and the sole of the foot
As an orthopedic surgeon is operating in the posterior compartment of the thigh, care is taken to preserve the arterial blood supply to the muscles in that region.

These are branches of which of the following arteries?
Deep femoral artery
(aka Deep profunda)

This branches into =
3ct
Lateral femoral circumflex artery
Medial femoral circumflex artery
Perforating arteries -
A patient has sustained lower limb trauma that has damaged the posterior tibial artery.
Therefore, you will be concerned about the blood supply to which of the following?
Posterior compartment of the leg and the sole of the foot

Muscles of the 2 compartments:
