Shoulder Flashcards
(107 cards)
The shoulder is susceptible to injury because _______
There is more mobility compromising the stability
This places great stress on the complex
Repetitive movements
Examples of repetitive movements
Throwing
Swimming
Serving in tenis or volleyball
FOOSHA
Falling on outstretched hand/arm
S shaped, 6 in long, supports anterior shoulder
Clavicle
Prone to fx because of shape and not protected
Clavicle
Flat, triangular, purpose is an articulating surface for the humerus
Scapula
Humerus structures
Head, neck, bicipital groove, greater and lesser tubercle and glenohumeral joint
Most frequent fracture
Clavicular
FOOSHA, direct impact, occurs in middle 3rd with athlete supporting arm, swelling deformity, point tenderness. They’ll often tip their head to the opposite side
Clavicular fracture
Direct blow or fall on arm with inability to move arm, swelling, point tenderness and discoloration
Humeral shaft fracture
Great danger to nerve and vessels, direct blow, discoloration, most likely at neck and can be mistaken for dislocation
Proximal humerus fracture
Young athlete 10 years and younger with a direct blow or indirect force applied to length of axis
Epiphyseal fracture
Brief translation of the humeral head without separation of the joint surfaces
Or in English, the joint comes out but goes back in
Subluxation
Most common dislocation
Anterior dislocation
Forced abduction, external rotation and extension, direct impact to the posterior or posteriolateral aspect with a flat deltoid, you can feel the humeral head and the athlete carries the affected arm in slight abduction and ER. They are unable to touch the opposite shoulder
Anterior dislocation
Forced adduction and IR or fall on outstretched and IR arm with labrum damage, severe pain and disability, limited ER and elevation
Posterior dislocation
Clavicle + manubrium of sternum, only direct connection between upper extremity and trunk
Sternoclavicular joint
Articulation disk that absorbs shock and allows movement
SC joint
Lateral end of clavicle and acromion process, weak junction
Acromioclavicular joint
Ball and socket joint, head of humerus and glenoid cavity of scapula held together by the glenoid labrum
Glenohumeral joint
Not a true joint, scapula + thoracic cage
Scapulathoracic joint
Pulls clavicle downward and toward sternum
Sternoclavicular ligament
What are you going to see in a grade 1 AC joint sprain
Mild point tenderness
Discomfort with movement
No deformity
Mild stretching of AC lig
