UPPER LIMB

Branches of axillary nerve with accompanying

blood vessels pass through the quadrangular inter-

muscular space

Loose fold of capsule of shoulder joint forms upper

boundary of the quadrangular intermuscular space.

Radial nerve and profunda brachii vessels course

through the lower triangular intermuscular space.

Only circumflex scapular vessels pass through the

upper triangular space.

Long head of triceps brachii is placed between

quadrangular and upper triangular spaces. Lower

down it forms a boundary of lower triangular space.

A patient came with njr.y on left shoulder region

after an accident. He was not able to abduct his

shoulder joint

o \A/hich nerve is injured?

. Where is the sensory loss?
Ans: Due to the injury to the surgical to the neck of
humerus, the axillary nerve got damaged. Patient
feels inability to abduct the shoulder joint.
The sensory ioss is over the lower half of deltoid
muscle and is called regimental/badge area due to
injury to upper lateral cutaneous nerve of the arm/ a
branch of the axillary nerve.
