Osteology

• Glenohumeral Mismatch

Warner & Caborn , 1992

Labrum

Negative Intraarticular Pressure

• Vaccuum effect

• Adhesion-cohesion

Capsuloligamentous Structures

Superior Glenohumeral Ligament

• Present in >90% of people

• Reinforces the rotator interval

• Limits inferior translation

• Limits ER– Adduction

• Limits posterior translation in– Flexion

– Adduction

– IR

Warner et al, 1992

Middle Glenohumeral Ligament

• Present in 60-80% of people

• Variable presentation

• Limits inferior translation– Adduction

– ER

• Limits ER– Adduction

• Limits AP translation in– Abducted (45º)

– ER

Inferior Glenohumeral Ligament

Complex• Anterior Band

• Posterior Band

• Axillary Pouch

• Functions in Abduction >45º

– Anterior translation in ER

– Posterior translation in IR

• Reciprocal tightening

and loosening of the

IGHLC

Posterior Capsule

• Thinnest portion (< 1mm thick)

• Limits posterior translation in:

– Flexion

– Adduction

– IR

Dynamic Restraints

•Concavity-Compression Effect

–Head centralization via cuff and biceps

•Rotator Cuff

•Periscapular Stabilizers

•Long Head of the Biceps

•Proprioception

Function of Rotator Cuff

• humeral head position control

• glenohumeral joint stability

Biomechanics

• Force couple

– maintain humeral head within glenoid

• compressive forces

– elevation and rotation

• Rotator Cuff Tear

– disruption of the force couple

– abnormal and unstable mechanical

• elevation with translation

SLAP Tear

• Onset

– Acute

– Chronic exertional

• Symptoms:

– Joint Line Pain

• Signs:

– Adduction Compression

– Shear maneuver

Internal Impingement

• Posterosuperior Glenoid impingement

– Symptomatic contact between the deep surface of the

rotator cuff tendons and the posterosuperior glenoid

Pathophysiology

• Contact occurs during

the late cocking/early

acceleration phase of

throwing with the arm

abducted and

externally rotated

10/8/2013

22

Pathophysiology“Subtle” anterior translation allows

further rotation

(“hyperangulation”-Jobe) and

impingement

Posterior Impingement Sign

• Late cocking position– 90-100 degrees of ABD

– 10-15 degrees of FF

– Maximal ER

• + when reproduces posterior pain

• 90% sensitive for tears of posterior labrum or partial thickness RC
