The shoulder

The Shoulder


Anatomy of the shoulder

Bones of the Shoulder

Clavicle

Scapula

Sternum

Humerus

Anatomy of the Shoulder


Joints of the shoulder

Acromio-clavicular

Sterno-clavicular

Gleno-humeral

Coroco-clavicular

Joints of the Shoulder


Motions of the shoulder

Motions of the Shoulder

  • Flexion

  • Extension

  • Adduction

  • Abduction

  • Internal Rotation

  • External Rotation


Ligaments of the shoulder

Ligaments of the Shoulder

  • Sterno-clavicular-ties sternum and clavicle

  • Acromio-clavicular-ties acromium and clavicle

  • Coroco-clavicular-ties corocoid process and clavicle

  • Transverse-holds long head of biceps in the bicepital groove

  • Gleno-humeral-ties glenoid and humerus

    • Superior

    • Middle

    • Inferior


Ligaments of the shoulder1

Ligaments of the Shoulder


Muscles of the shoulder

Sterno-cleomastoid

Billaterally flexes the neck

Unilaterallty rotates the head

Pectoralis Major

Shoulder Flexion

Trapezius

Elevates/Depresses shoulder

Extends Head

Adducts Scapula

Protracts Shoulder

Holds scapula to body

Muscles of the Shoulder


Muscles of the shoulder1

Rhomboids

Elevates and protracts scapula

Serratus Anterior

Lack of development causes winged scapula

Muscles of the Shoulder


Muscles of the shoulder2

Deltoid

Ties scapula and clavicle to deltoid tuberosity

Anterior, Middle, and Posterior

Abduction

Latissimus Dorsi

Forms posterior wall of the Axilla

Seldom injured

Internal rotation, extension, adduction, depression

Muscles of the Shoulder


Internal muscles of the shoulder

Internal Muscles of the Shoulder

  • All are part of Rotator Cuff

  • Remember by acronym SITS

  • Commonly injured in throwing motions

    • Subscapularis

    • Supraspinatus

    • Infraspinatus

    • Teres minor


Muscles of rotator cuff

Muscles of Rotator Cuff

  • Subscapularis

    • Most anterior muscle

    • Becomes stretched in a dislocation

    • Internal Rotation


Muscles of the rotator cuff

Muscles of the Rotator Cuff

  • Supraspinatus

    • Abduction

  • Infraspinatus

    • External Rotation

  • Teres Minor

    • External Rotation


Shoulder injuries

Shoulder Subluxation

Fractured Clavicle

Shoulder Dislocation

AC Joint Injuries

Rotator Cuff Impingement

Humeral Fracture

Biceps Tendonitis

Bursitis

Myositis Ossificans

Frozen Shoulder

Glenoid Labrum Injuries

Shoulder Injuries


Shoulder subluxation

Shoulder Subluxation

  • Shoulder slips out then reduces on it’s own.

  • Mechanism of injury is falling on an outstretched arm


Fractured clavicle

Fractured Clavicle

  • Most frequently fractured bone

  • Lateral 1/3 is the weakest portion

  • Ice and Immobilize


Shoulder dislocation

Shoulder Dislocation

  • Mechanism of Injury is falling on outstretched arm

  • Types of Dislocation

    • Anterior

    • Inferior

    • Posterior


Ac joint sprains

AC joint Sprains

  • 1st degree

    • Some stretching of ligament

    • No obvious deformity

    • Pt tenderness over AC joint

    • 7-10 days

  • 2nd degree

    • Some or complete tearing of AC ligament

    • Joint Laxity

    • MD Referral

  • 3rd degree

    • Complete loss of AC and CC ligaments

    • Arm Hangs in place

    • Usually surgical repair is needed


Rotator cuff impingement

Rotator Cuff Impingement

  • Cuff is swollen or irritated

  • Pain in raising the arm


Labrum tears

The glenoid labrum deepens the glenoid cavity

It is a cartilage ring

Causing clicking in the shoulder

Usually repaired or resected

Labrum Tears


Fractured humerus

Fractured Humerus

  • Caused by direct blow or falling on arm

  • Needs surgical repair


Little league shoulder

Little League Shoulder

  • Caused by too many curve balls

  • Fx of epiphyseal plate

  • Rest for 2 weeks


Biceps tendonitis

Biceps Tendonitis

  • Long head of biceps rubs transverse ligament

  • Severe cases becomes so inflamned it decays

    • Rest Modalities

    • Can lead to surgical intervention if not cared for


Bursitis frozen shoulder

Bursitis (Frozen Shoulder)

  • Sub Acromial Bursa inflamed

  • Could lead to Frozen Shoulder where bursa hardens and restricts motion


Myositis ossificans

Myositis Ossificans

  • Same as Quadriceps

  • Repeated blows to the same area

  • Frequently occurs in the belly of biceps
