Fracture in the Arm
- Anatomy
- Muscles
- Biceps Brachii
- Origin : 1- long head:
supraglenoid tubercle of
the scapula within the
shoulder joint . 2- Short
head : Tip of the
coracoid process in
common with the
coracobrachialis
- Insertion : 1- by a strong
tendon into the posterior
rough part of the radial
tuberosity . 2- by the bicipital
aponeurosis arises from the
tendon of the biceps to blend
with the deep fascia of the
forearm .
- Action : Both heads Supination
of the flexed forearm Flexion of
the elbow joint The short head
is a weak flexor of the shoulder
joint The long head prevents
the upward dislocation of the
shoulder joint

- AXILLARY
- passes infront the subscapular muscle,
to the quadritriangular space into the
posterior side of humerus where is
meets it companion posterior
circumflex humaeral artery and
surrounds surgical neck of humerus. so
any fracutre will not only lead to
hemorrhage but also to damage to this
nerve therefore damage to deltoid and
teres minor movements. while the
radial nerve will move backword
through the lower quadrangular
space.

- extension
of triceps
- Arises from brachial plexus in
root of neck and under the cervix
to behind the humerus forming

the lower triangular spaceand
then goes anteriorly into the

then continous into the forearms
as superficial radial nerve to
supply foramrs muscles like
brachioradialis muscle and more

- Musculocatanous
- root value: c5-c6-c7 (lateral cord)
- no circumflex unlike the radial
and axillary.
- supplying: bbc muscles : first branch
–coracobrachialis second branch-biceps
third and last branch-brachials. and then
supplies the lateral skin or cutanous of
forearms as it continous. not seen only
when biceps are removed!!

- root value: c5-c6-c7 (lateral cord)
- Ulnar
- ulnar nerve is in very
dangerous site cuz its
exactly in the elbow joint.
so if u had any frature of
dislocation of elbow joint
then u ulnar nerve is
most prone to any sort of
damage like hemorrhage.

fingers of
the hand

- Median
- (lateral and medial cord)
- no single branch in the arm
- it does supply or innervate
the first 2 fingers on
lateral side (thumb). the
last 2 fingers by ulner
nerve. it is anterior to the
medial epicondyl or it sits
on the coronoid fossa
while the ulner nerve is
posterior to medial
epicondyl or postrior to
coronoid fossa. (it will
enter coronoid fossa most
medially)
