Transcript Elbow Jointx

Intro to the Elbow
• Elbow Joint = Hinge Joint
• Non-weight bearing bone, but still sustains significant loads
• Three Joints:
• Humeroulnar Joint (Flex/Ext)
• Humeroradial Joint (Flex/Ext)
• Radioulnar Joint (Pronation/Supination)
• ROM: Flexion, Extension, Pronation, Supination
• Acute Injuries: Fractures, Dislocations, Sprains, Strains,
Acute Bursitis.
• Chronic Injuries: Bursitis, Impingement, Epicondylitis
joints
• Reminder: A joint is where two
bones meet!
• Humeroulnar Joint = Trochlea
of the Humerus & the Proximal
Ulna.
• Humeroradial Joint = Capitulum
of the Humerus & the Proximal
Radius.
• Radioulnar Joint = Head of the
Radius & Radial notch of the
Ulna. *Held together by the
annular ligament*

Helpful vocabulary
• Valgus Stress: A force that is applied laterally causing
the distal portion of the extremity to go away from the
midline.
Helpful vocabulary
• Varus Stress: A force that is applied medially causing
the distal portion of the extremity to go toward the
midline.
Varus/valgus
• Known as “Carrying Angle”
Helpful vocabulary

Fractures of the
elbow/forearm
• Fractures can to occur to the:
• Area of the condyles
• Olecranon
• Head of the radius
• Radius
• Ulna (AKA – “Nightstick FX”)
• MOI: Fall on outstretched hand, direct blow, valgus/varus stresses.

Elbow dislocation
• Usually involves a posterior displacement of the radius and ulna on the humerus.
• MOI: Hyperextension, fall on outstretched arm, sudden forceful valgus or varus
blow.
• S&S:
• Snapping or cracking sensation upon impact
• Immediate severe pain, swelling, and loss of function
• Profuse swelling
• Obvious deformity
• Elbow appears fixed in flexion with a prominent olecranon; forearm appears
shortened
• Numbness
Elbow dislocation
• Associated Conditions:
• Ruptured ulnar collateral ligament
• Fracture of radial head or olecranon process
• Neurovascular compromise
• Treatment:
• Carefully stabilize joint so as not to disrupt the ulnar nerve or
brachial artery
• Assess distal sensation, radial pulse, and capillary refill before/after
splinting
• Immediate physician referral

Elbow contusion
• Common to the olecranon due to
general vulnerability.
• Common in contact sports.
• MOI: Direct contact
• S&S: Pain, swelling, ecchymosis,
minor loss of function, point
tenderness.
• Treatment: PRICE method
• Prevention: Elbow pads, teach athletes
how to fall properly to avoid injury.
Olecranon bursitis
• Bursa lies between the olecranon process and the skin.
• Vulnerable to injury due to its superficial location.
• MOI: Direct contact (acute) or repeated stressful
motions (chronic).
• S&S: Pain, instantaneous swelling, point tenderness.
• Treatment: PRICE method.
• Prevention: Protective equipment such as elbow pads.

Ulnar nerve impingement
(Cubital tunnel syndrome)
• Impingement = Pinching of soft tissue,
such as a bursa, tendon, or a nerve,
between the ends of two or more bones.
• The Ulnar Nerve becomes impinged or
compressed.
• The Ulnar Nerve runs through the
“Cubital Tunnel.” AKA Cubital Tunnel
Syndrome
• MOI: Repeated stress or a direct blow.
• S&S: Point tenderness, pain with and
without motion, numbness, tingling
sensation, possible loss of strength.
• Special Tests: Tinel’s Sign
Ulnar nerve

Biceps brachii rupture
• Muscle Rupture = a complete tear of a muscle.
• The biceps brachii can be ruptured by pulling motions.
• Most commonly occurs to gymnasts, rowers, and weight
lifters.
• Rupture will commonly occur at the point of origin,
however a bulging deformity will appear in the muscle
belly. AKA – “Popeye Muscle”
• S&S: Pain, deformity, bulging biceps, ecchymosis, loss
or decrease of mobility. Sometimes the athlete will hear
a “pop” when the muscles tears.
Biceps brachii rupture
• Treatment: Place the athlete in the most
comfortable position possible. Immobilize the
upper arm using a splint and/or sling. Refer
the athlete to a physician for further
evaluation.
• Prevention: Athletes should stay within their
tolerance limits when training and competing.
Therefore, they should not push themselves
beyond their muscle tolerance or endurance.

Sprains
• Can occur to Radial Collateral Ligament (RCL) or
Ulnar Collateral Ligament (UCL).
• MOI: Fall on an outstretching arm resulting in
hyperextension, valgus force (UCL injury), or varus
force (RCL injury).
• S&S: Localized pain, point tenderness, swelling,
instability.
• Special Tests: Valgus Stress Test, Varus Stress Test.

epicondylitis
• Epicondylitis = inflammation of the medial or lateral
epicondyle of the humerus and its surrounding tissues.
Medial epicondylitis
• Inflammation of the medial
epicondyle of the humerus and its
surrounding tissues.
• Also known as “ little league
elbow” or “golfer’s elbow”
• Affects the flexor muscles.
• MOI: Chronic overuse of flexor
muscles.
• S&S: Pain and point tenderness that
is localized to the medial
epicondyle. In some cases swelling
may be present.
• Special Test: Medial Epicondyle
Test
Lateral epicondylitis
• Inflammation of the lateral
epicondyle of the humerus and
its surrounding tissues.
• Also known as “tennis elbow”
• Affects the extensors muscles.
• MOI: Chronic overuse of
extensor muscles.
• S&S: Pain and point tenderness
that is localized to the lateral
epicondyle. In some cases
swelling may be present.
• Special Test: Lateral Epicondyle
Test
Epicondylitis Treatment
• Treatment: PRICE. Evaluate and
correct the athlete’s mechanics to
decrease stress on the elbow joint.
If symptoms do not improve the
athlete should see a physician. In
some cases a counterforce strap
can help relieve the pain of
epicondylitis.
• Prevention: Proper body
mechanics should be emphasized
to player of sports involving
repeated motions at the elbow
joint such as javelin, tennis,
racquetball, baseball, etc.
Volkmann’s
contracture
• Volkmann’s contracture = contracture and damage to the
muscles of the forearm because of injury to their blood supply.
• Injury that may occur when swelling, muscle spasm, bone
displacement, or a bone fracture near the elbow puts pressure
on the arteries in the arm.
• The pressure decreases the blood supply to the hand and
forearm resulting in muscle damage and possibly paralysis.
• There will be an absent or diminished brachial and radial pulse.
• This is a medical emergency, activate EMS!

supinated and the elbow flexed to 90 degrees. Place
one hand on top of the athlete’s wrist and use your
other hand to stabilize the elbow. Instruct the athlete
to flex their arm against your resistance.
• Extension: With the athlete sitting, ask the athlete to
face you with the arm flexed at a 90 degree angle.
Place one hand on the back of the athlete’s wrist and
use your other hand to stabilize the elbow. Instruct the
athlete to extend the arm against your resistance.
Manual muscle tests
• Pronation: Ask the athlete to face you with the
forearms supinated and the elbow flexed to 90 degrees.
Place your hands on the bottoms of the athlete’s
hands, grasping the medial aspect of the hand.
Instruct the athlete to pronate their forearm against
your resistance.
• Supination: Ask the athlete to face you with the
forearms pronated and the elbow flexed to 90 degrees.
