Clinical Concerns
Concerns
Tennis Elbow (elbow tendinitis)
Inflammation, soreness, or pain on the outside
(lateral) side of the upper arm near the elbow.
There may be a partial tear of the tendon fibers,
which connect muscle to bone. The tear may be
at or near where these fibers begin, on the
outside of the elbow
Cause
The part of the muscle that attaches to a
bone is called a tendon. Muscles in your
forearm attach to the bone on the
outside of your elbow. When you use
these muscles over and over again,
small tears develop in the tendon. Over
time, this leads to irritation and pain
where the tendon is attached to the
bone
Cure
Put ice on the outside of your elbow 2 - 3
times a day.
Take nonsteroidal anti-inflammatory
medications
An occupational therapist can show you
exercises to stretch and strengthen the
muscles of your forearm
Surface Anatomy
Lateral Epicondyle
•
A small, tuberculated eminence, curved a little
forward, and giving attachment to the radial collateral
ligament of the elbow-joint,
Medial Epicondyle
•
•
•
Larger and more prominent than the lateral
epicondyle,
It gives attachment to the ulnar collateral ligament of
elbow joint.
The ulnar nerve runs in a groove on the back of this
epicondyle
Surface Anatomy
Radial styloid process
• A projection of bone on the lateral surface
of the distal radius bone. It extends
obliquely downward into a strong, conical
projection. The radial collateral ligament of
the wrist attaches at its apex.
Ulnar styloid process
• Projects from the medial and back part of
the bone; it descends a little lower than the
head, and its rounded end affords
attachment to the ulnar collateral ligament
of the wrist-joint.
Surface Anatomy
Cubital fossa
The shallow triangular depression on the anterior
surface of the elbow.
• The cubital fossa contains four main vertical
structures (from lateral to medial: Radial Nerve,
Biceps brachii tendon, Brachial artery, Median
nerve.
Superficial
dissection
Olecranon
• A large, thick, curved
bony eminence of the
forearm that projects
behind the elbow.
Deep
dissection
Surface Anatomy
Carrying Angle
The way the forearm
angles away from the
body when something is
carried, such as a pail of
water. More pronounced
in women than men.
Surface Anatomy
Medial bicipital groove
•
On the surface anatomy of the upper arm. It is
formed by the hollow between the biceps
and triceps muscles
 Tendons are tough strips of tissue that connect
muscles to bones and allow us to move our limbs.
Triceps tendon
•
Attaches the ulnar bone at the elbow
Biceps tendon
•
Attaches to the radius bone at the elbow
Nerves
• Median Nerve
• Radial Nerve
• Ulnar Nerve
• Musculocutaneous
Nerve
Arteries
Brachial artery
•
Provides the main arterial supply to the
arm and is the continuation of the axillary
artery.
Ulnar artery
•
Decends through the anterior
compartment of the forearm, deep to the
pronator teres.
Radial artery
•
Leaves the forearm by winding around
the lateral aspect of the wrist and crossing
the floor of the anatomical snuff box to
reach the hand.
Arteries
Recurrent interosseous artery
Anterior interosseous artery
Posterior interosseous artery
Superficial palmar arch
•
Formed predominantly by the ulnar artery with
a contribution from the superficial palmar
branch of the radial artery.
Deep brachial artery
(Profunda)
•
Largest branch of the brachial artery in the
upper part of the arm .
