Shoulder Assessment And Injuries Flashcards
What is the biomechanics of the shoulder?
It’s a ball and socket joint called the glenohumeral joint
Comprises if the glenoid cavity that’s stabilized by ligaments,the labrum
And then other muscles
What provides static stabilization?
The anterior and posterior bands of the anterior glenohumeral ligament which attaches to the labrum
What is the purpose of the anterior band of the inferior GH ligament?
Prevents Anterior and posterior translation of the humeral head
What is the labrum?
Ring of fibrous tissue attached to the rin of the glenoid
What are the dynamic stabilizers?
The rotator cuff
What is the purpose of the rotator cuff muscles?
They control the position of the humeral head
Work with the scapulohumeral rhythm
What are the scapula stabilizers?
The traps
Serratus anterior
Rhomboid major and minor
What is the scapulohumeral rhythm?
Ration of glrnohumeral movement to scapulothoracic movement when the shoulder elevates
What is shoulder impingement?
It is a symptom that the rotator cuff muscles are impinged as the pass through the subacromial space
What is primary external impingement?
When the structural space starts to narrow and pain occurs and dysfunction occurs
Swelling if soft tissue in the subacromial space
What is secondary impingement?
Functional problems occur
What are the types of impingement tests?
Kennedys
Neer
Full Can
Jobes
Why is the Kennedy test done?
To identify possible subacromial impingement syndrome and the test is when patient feels pain when there’s internal rotation done
Why is the Neer Test done?
To see if there is a subacromial impingement and the test will be positive if there is pain in the anterior shoulder
And if there’s internal impingement in the posterior shoulder
Why is Jobes test done?
To assess for leisons on the rotator cuff especially the supraspinatus muscle and tendon
And it’s positive if there’s subacromial impingement and negative if there’s internal impingement
Why would shoulder instability occur?
When the shoulder capsule,ligaments or labrum become stretched torn or detached completely out the socket
What is used to detect SLAP leisions?
The Bicep Load Test 2
What are SLAP Leisons?
Superior labral anterior posterior injuries of the glenoid labrum
What is the diffrence between SLAP and non SLAP injuries?
SLAP is when the labrum is injured extending from anterior to the biceps tendon to the posterior to the tendon and non SLAP is degenerative flat vertical labradorite tears and bankart lesions injury to the anterior labrum following anterior dislocation
What is the O brien test known as?
Active compression test
What does the O brien test indicate?
Potential SLAP leison or acromioclavicular leisons that cause pain
