Q.1

Roots involved in Erb's palsy are :-

A. Anterior primary rani of C5-C6

B. Posterior primary rami of C6- C7

C. Posterior primary rami of C8-T1

D. Posterior primary rami of C7-C8

Explanation :

Erb's point is formed by the roots of C5 and C6, anterior and posterior divisions of upper trunk, suprascapular nerve and nerve to subclavius muscle. So the nerve root involved in Erb's palsy is C5 and C6.

Q.2

Axillary abscess is safely drained by which approach :-

A. Floor

B. Lateral

C. Anterior & posterior circumflex humeral

D. Medial

Explanation :

Axillary abcess should be incised through the floor of axilla, midway between the anterior and posterior axillary folds,and nearer to the medial wall in order to avoid injury to the main vessels running along the anterior,posterior and lateral walls.

Q.3

Infection of index finger spread to

A. Mid-palmar space

B. Radial bursa

C. Dorsum of hand

D. Thenar space

Explanation :

Infection of thumb and index finger spreads to thenar space. Infection from middle, ring and little finger spreads to midpalmar space.

Q.4

Froment's sign is characteristically seen in -

A. Intercostobrachial nerve injury

B. Radial nerve injury

C. Median nerve injury

D. Ulnar nerve injury

Explanation :

Froment’s sign is tested for Ulnar nerve injury, by holding a book between the thumb and other fingers. When an ulnar nerve injury is there, adductor pollicis and first palmar interossei are paralysed. This cause the flexor pollicis longus to function while holding the book in a prominent manner of flexion.

Q.5

Which tendon is frequently absent in upper limb?

A. Palmaris longus

B. Extensor carpi radialis brevis

C. Flexor digitorum profundus

D. Flexor carpi ulnaris

Explanation :

The palmaris longus may not always be present. It has a short belly and long tendon.It originates from medial epicondyle of humerus. Distally, it passes over the flexor retinaculum with which its fibers mingle and is attached to the palmar aponeurosis.

● Lateral

● Tendon of abductor pollicis longus

● Tendon of Extensor pollicis brevis

♦ Floor

● Proximally-styloid process of radius

● Distally-base of rst metacarpal bone of thumb

♦ B/w these bones , beneath the oor lies the scaphoid & the trapezium (felt but not identiable)

♦ Radial Artery - Can be palpated

♦ Cephalic vein - Can also someti mes be recognised crossing the box as it ascends the forearm Mnemonics Floor -

FiRST Fi- First Metacarpal bone R- Radial Styloid S-Scaphoid bone T- Trapezium Contents - VAN V- Cephalic vein A - Radial artery N - Radial Nerve (cutaneous Branch)

Clinical signicance of anatomical snuff box:

• The pulsations of radial artery can be felt in the anatomical box.

• The tenderness in the anatomical box indicates fracture of scaphoid bone.

• The cephalic vein at this site is often used for giving intravenous uids.

• The supercial branches of the radial nerve can be rolled over the tendon of extensor pollicis longus.

Anatomical Snuff Box Anatomical Snuffbox is a triangular depression on the lateral aspect of wrist immediately distal to the radial styloid process,

that becomes prominent when thumb is fully extended Boundaries Floor Contents Lateral /Anterior wall

● Abductor Pollicis longus (Radially)

● Extensor Pollicis Brevis (Medially') Medial /Posterior wall

● Extensor Pollicis

● Radial styloid

● Scaphoid (smooth convex articular surface)

● Trapezium

● Base of First Metacarpal

● Cephalic vein

● Radial artery

● Supercial radial nerve

Q.7

A cut injury of the ulnar nerve results in :-

A. Total claw band

B. Paralysis of all lumbricals

C. Paralysis of all slips of the flexor digitorum profundus.

D. Paralysis of all interossei

Explanation :

Ulnar nerve injury causes

- Paralysis of all interossei

- Medial two lumbricals paralysis

- Hypothenar muscles paralysis

- Adductor pollicis paralysis

- Flexor carpi ulnaris paralysis

- Medial two slips of flexor digitorum profundus paralysis

- Ulnar claw hand

Q.8

In deltoid paralysis, which nerve is involved -
a) Circumflex N
b) Musculocutaneous N
c) Axillary N
d) Radial N

A. AC

B. ABC

C. AD

D. BA

Explanation :

Other name of axillary nerve is circumflex nerve.

Q.9

While exposing the kidney from behind, all of the following nerves are liable to injury except:

A. Subcostal nerve

B. Iliohypogastric nerve

C. Ilioinguinal nerve

D. Lateral cutaneous nerve of thigh

Explanation :

Posterior relations of the kidney:

Diaphragm
Medial and lateral arcuate ligaments
Muscles:

Psoas major
Quadratus lumborum
Transversus abdominis

Subcostal vessels
Nerves:

Subcostal nerve
Iliohypogastric nerve
Ilioinguinal nerve

12th rib (11th rib and 12th ribs in left kidney)

Q.10

An inhaled foreign body is likely to lodge in the right lung due to all of the following features except:

A. Right principal bronchus is more vertical than the left bronchus

B. Tracheal bifurcation directs the foreign body to the right lung

C. Right inferior lobar bronchus is in continuation with the principal bronchus

D. Right lung is shorter and wider than left lung

Explanation :

An foreign body is more likely to get lodged in the right lung as the right bronchus is wider, shorter and more vertical

Q.11

After radical mastectomy there was injury to the long thoracic nerve. The integrity of the nerve can be tested at the bedside by asking the patient to :

A. Touch the opposite shoulder

B. Shrug the shoulders

C. Raise the arm above the head on the affected side

D. Lift a heavy object from the ground

Explanation :

Long thoracic nerve (Nerve of Bell) supplies the serratus anterior muscle

Serratus anterior rotates the inferior angle of scapula laterally during abduction of the arm above the head – hence it is impaired in injury to long thoracic nerve

Winging of scapula is another classical feature of long thoracic nerve injury
