New Concepts and Advances
(Arthroscopic) for the
Treatment of Shoulder Pain
William F Bennett MD
The Simple Shoulder

While a complex joint with complex
function, general approaches to determining
the non-descript, cause….is easy!

I.e., intrinsic versus extrinsic
Intrinsic versus Extrinsic
Intrinsic- later and more descript…means
pain coming from the shoulder joint itself
 Extrinsic- pain that may cause shoulder pain
but comes from sources outside the
shoulder

Extrinsic






Most common- cervical spine
Pancoast tumors of the lung
Thoracic spine
Peritoneal/Splenic irritation can cause pain at
Erb’s point
Angina/MI
Metabolic/Oncologic problems, ie., bone marrow
involvement like lymphoma/leukemia, parathyroid
Extrinsic-Cervical Spine

General rule-trapezial pain-cervical
-deltoid pain- intrinsic or from the shoulder
Can have both shoulder and cervical spine
affected which makes it more difficult
Cervical spine may have radicular
involvement
Intrinsic

Once extrinsic has been ruled out then one
can focus on the intrinsic causes.
 If a certain shoulder motion whether it be
flexion, abduction, external rotation or
internal rotation causes pain in the deltoid
area and not in the trapezial area, one is
probably dealing with an intrinsic problem
Before discussing intrinsic
Causes
Lets diverge and discuss the anatomy
and function of the shoulder
Anatomy

4 joints-two are articulations
– Glenohumeral joint
– Acromioclavicular joint
– Scapulothoracic articulation
– Sternocalvicular articulation/joint
– Discuss Bones-Bone models
Ligaments/Capsule

Capsule is the “sac”
– Normal sac allows motion in various planes
– Abnormal sac restricts motion in various planes

Ligaments- hold bone to bone
–
–
–
–
Glenohumeral ligaments
Coracohumeral ligaments
Coracoacromial ligaments
Coracoclavicular ligaments
Muscles/Tendons

Rotator Cuff are a confluence of 4 tendons from
the following respective muscle bellies
–
–
–
–
Supraspinatus
Subscapularis
Infraspinatus
Teres minor
– Biceps
– Deltoid
Bone models
Bursae/Cartilage/Meniscus

Subacromial Bursae
 Subdeltoid bursae
 Subcoracoid bursae
 Glenohumeral articular cartilage
 Acromioclavicular meniscus
Intrinsic Diagnoses

Impingement
– Tendonitis
– Bursitis
– Rotator Cuff tear-complete
– Rotator Cuff tear-partial
– others
Intrinsic Diagnoses

Acromioclavicular joint irritation/arthritis
 Glenohumeral joint osteoarthritis
 Rheumatologic joint
 Pigmented Villonodular synovitis
 Chondrometaplasia
 Tumors-giant cell, synovial sarcoma
Intrinsic Diagnoses

Instability/Subluxation-repetitive/chronic
Atraumatic/multidirectional

Dislocation
– Traumatic unidirectional

Biceps
– Inflammation
– Instability/subluxation
– Tendonitis/avulsion
Intrinsic Diagnoses

History compatible
 Physical exam compatible
 Radiologic exam compatible
 MRI/MRA compatible
 Less so- blood work, others
– Each is a piece of the puzzle
Treatment

“ITIS”- inflammation- tendonitis, bursitis
– Rest, avoidance, NSAIDS, injections, therapy

Osteoarthritis- above plus possible total shoulder
replacement
 Rotator Cuff Tears-above +/- repair
 Instability/Dislocation-+/- repair
– The arthroscope has become an important tool for
diagnosis and treatment in virtually all afflictions of the
shoulder
Arthroscope

Fiber optic device
 Triangulate-the surgeon never sees the
actual inside of the joint- it is projected
upon a monitor and as such, the working
tools, “triangulate’ to the point of focus
 Minimally invasive
 Less pain
 Less rehabilitation
Shoulder Pain-traditionally
was treated with long delays
in surgical intervention-Why?

Shoulder pathology not well understood by all
orthopedists
 Open repair required extensive incisions
 Rehabilitation was long
– Most importantly, the primary care givers was in
general, “under-the-impression” that shoulder surgical
intervention was not that effective
Arthroscopic Intervention
utilized in

Impingement-bursitis, tendonitis
 Rotator cuff tears
 Instability or dislocation
 AC joint arthritis

And yes even in Osteoarthritis
Arthroscope has allowed for
the further identification of
subtle shoulder pathology,
previously not identified

Natural History of Rotator Cuff
Tears

Recurrence of pain
 Tears get bigger with time
 Results of surgical intervention deteriorates
with time
 Muscle turns to fat
 Tendon becomes inelastic
At this Point

can repair various intrinsic problems in the
shoulder
