Review the anatomy of the shoulder
Review the biomechanics of the shoulder
Briefly touch on the physical examination of the shoulder,
namely ROM
Practice Assessing the shoulder looking for somatic
dysfunction
 SC/AC/GH Joints, Scapulothoracic Articulation
Practice correctly naming shoulder somatic dysfunction
Practice the OMM treatments for shoulder somatic
dysfunctions
 Springing/Ligamentous Balance/Articulatory/Muscle
Energy/7 Stages of Spencer (Spencer Technique)



A loosely constructed, highly mobile complex
of bones, muscles and ligaments
The humerus is suspended from the scapula by
soft tissue, muscles, ligaments and a joint
capsule
Designed for increased mobility with only
sufficient stability to provide a proper
foundation for muscular function


Composed of 3 joints & one articulation
Sternoclavicular joint (SC)
 Acromioclavicular joint (AC)
 Glenohumeral joint (GH)
 Scapulothoracic articulation


All four work together in a synchronous
rhythm for universal motion.




Saddle shaped synovial joint
Articular disc separates the articular surfaces
and adds significant strength to the joint
Depends on capsular ligament for strength
Enables the humerus to achieve 1800 of
ABduction


A plane synovial joint
that augments the
range of motion
(ROM) in the humerus.
It is made up of the
acromion process of
the scapula and the
lateral edge of the
clavicle.



It is surrounded by a fibrous
capsule and an articular disc
separates the surfaces.
Primary strength is supplied
by the acromioclavicular and
coracoclavicular ligaments
Coracoclavicular ligaments
stabilize the clavicle to the
scapula
Conoid ligament primarily
prevents anterior and superior
clavicular displacement
 Trapezoid ligament is the
primary constraint against
compression of the distal
clavicle into the acromion






Multi-axial ball and socket
Most of the support is
provided by the rotator cuff
(RC)
Contraction of RC pulls the
humerus down into
lower/wider portion of the
glenoid cavity
Without the “dropping
down”, full ABduction is
impossible
Hydrostatic component



Labrum–ring of
fibrocartilage that
surrounds and deepens
the glenoid fossa
Increases the available
contact area to
approximately 70%
Only part of the
humeral head is in
contact with the
glenoid at any one time




Also called scapulocostal joint
Body of the scapula and the
muscles covering the
posterior chest wall
Scapula serves as a mobile
platform from which the
upper limb operates
Allows the scapula to glide
medially, laterally, superiorly
and inferiorly and rotate over
the posterolateral chest cage



Scapula aligns itself to
allow the glenoid cavity to
be in the best position to
receive the head of the
humerus
Neurologically complex
Movement of the scapula,
humerus and clavicle are
necessary for normal
scapulohumeral ABduction


Pain or stiffness may disturb synergy of motion
The GHJ moves 120 degrees as the scapula
swings about 60 degrees around the chest wall
in a smooth 2:1 ratio.

Physician stands at head of table
Patient is supine
Place tips of your fingers on the
superior edges of the medial
ends of the patient’s clavicle
Ask your patient to shrug their
shoulders. Both clavicles should
move into ABduction, and the
medial clavicles should move
inferiorly (inferior glide)
In the absence of trauma, the
dysfunctional (restricted)
clavicle stays superior at the SC
jointNamed an ADduction
somatic dysfunction (superior
glide)

with their arms. Their scapulae should come
off the table. Both clavicles should move
into horizontal flexion, and the medial
clavicles should move posterior (posterior
glide)
In the absence of trauma, the dysfunctional
(restricted) clavicle stays anterior at the SC
jointNamed a horizontal extension
