IRAT 1 Flashcards
Shoulder complaints are classified most commonly into
Sports injuries
Wear and tear repetitive stress injuries
Traumas
Certain arthridities
In the case of trauma, what damage must be suspected
Fracture Dislocation Tendon Labrum Ligament
The shoulder can also be the sight of pain from referred
Cervical spine or thoracic spine injury or subluxation and/or from visceral sources such as heart, lung, diaphragm, or gallbladder
Less common sources of shoulder pain might be from
Tumors or infection and peripheral nerve entrapments
The most common presentation of soulder complaints include
Instability - trauma/non-truama
Impingement: tendons, bursae, ligament
Tendinitis/bursitis
Osteoarthritis
Adhesive capsulitis (frozen shoulder) - esp age 40-60ish
AC joint separations (look at ligament derangement)
C/spine referred pain patterns
Arthritidies that commonly affect the shoulder are
AS and rheumatoid
In severe cases of arthritidies of the sohoulder, the ___ can rupture
Supraspinatus tendon
In seniors, ___ is common and so is ____.
OA
Adhesive capsulitis
OA can also appear in younger populations following
Truama
Always take a thorough history so as to establish
Quality of the complaint Site Trauma MOI Activities of patient ROM Past injuries Weakness Instability Sensory loss High or low-end user
High end user
Athlete
Low-end user
Sedentery office worker
Pain localization anterior traumatic
Fracture, dislocation, sub-ac bursitis, capsular spriain, tendon rupture (long head of biceps), labrum tear
Non-traumatic pain locatlization
Impingement, biceps tendinitis, sub-ac bursitis, subscapularis tendonitis, subluxation, etc
Trauma
Look for dislocation/separation and fracture.
Typical types or presentaions of trauma are
Blows (contusion)
Falls (AC separation, clavicle fractures)
FOOSA/H injuries (AC separation, dilocation, and labrum tears)
Traction of the arm (brachial plexus injuries, subluxation)
Sudden pain when lifting heavy object (tendon rupture, labrum tear
Blows
Contusions
Falls
AC separation, clavicle fractures
FOOSA/H injuries
AC separation, dislocation, labrum tears, rotator cuff tears
Arm forced into certain positions and jammed or wrenched
Dislocation and labrum tears
Traction on the arm
Brachial plexus injuries, subluxation
Sudden pain when lifting heavy object
Tendon rupture, labrum tear
Pain
Acute or chronic
Acute pain without trauma may indicate
Burisitis if ROM is decreased
Chrnoic pain without trauma
Adhesive capsulitis
Weakness or instability is highly suggestive of
Un-rehabilitated capsular ligament injury and can lead to concomitant damage to the labrum
Nerve damage will show
Evident atrophy of the associated muscle.
Brachial plexus controsl
Upper extremity and subluxation or nerve root damage will result in weakness
With weakness might also be possibility of
Inherent shoulder capsule weakness which is usually bilateral and can be determined with orthopedic testing
Stiffness and restriction must be assessed initially with
Thorough history
Acute pain without any recent trauma that lasts for weeks before eventually becoming stiff is likely to be
Adhesive capsulitis
Post-traumatic pain will lead to other obvious conclusions such as
Dislocation or separation
History of trauma and/or surgery with resultant pain/restriction leads to
OA
Restriction due to pain and weakenss is likely caused by
Bone blockage or labrum pathology
Overuse or trauma to a muscle can lead to
Scar tissue and restriction in the direction of stretch
Painful arc is considered to be
Between 70-110 degrees
X-ray is generally filmed based on
Suspected underlying condition
Most common x-ray for shoulder
AP
Utilized for AC spot shot and osteolysis of the distal clavicle
Zanca or Z view (15 degrees cephalad)
View for Bankart lesion (glenoid lip avulsions associated with labrum teras)
West Point view
view for a Hill-Sachs lesion also a labrum tear findings
Stryker-notch
Used as a tool when patients are not responding to conservative care and can be helpful in discerning labrum tears, but not entirely reliable
MRI
Views used for labrum tears and rotator cuff tears and tend to be the imaging methods of choice
CT and CT arhtrogram
Used to determine full-thickness rotator cuff tears
US
If AS rheumatoid or other arthitides are suspected based on plain film
Lab exams for HLAB27 and rheumatoid factor may be ordered but appropriate referral to rheumatologist is suggested
If x-ray reveals infeciton, fracture or tumor
Referral to orthopedic specialist
If patient is unable to tolerate an un-medicated course of care and treatment, then
Referral out is necessary
PT is beneficial in causes of
Acute pain
Therapeutic rehab might consist of
PNF stretching, cross friction massage, myofscial release, isometrics, stabilization (strapping/taping) and strenghtening
Stability and technique must be strong considerations to adjustments to
Shoulder and upper extremity kinetic chair
The shoulder joint type
Ball and socket joint
Shoulder joint complex
Articulation of the humerus and the glenoid fossa of the scapula
4 joints in shoulder joint complex
Gleno-humeral
Acromio-clavicular
Sterno-clavicular
Scapulo-thoracic
Nerve supply shoulder joint complex
Fifth through seventh cervical nerve roots via its formation into the brachial plexus.
On the lateral aspect of the shoulder, the skin is innervated by a cutaneous branch of the axillary nerve
ROM shoulder
Ext rotation 108
Int rotation 72
With the arm at 90 of abduction, total rotational arc is 120
Primary muscles in shoulder joint complex
Trapezius Levator scapulae Rhomboid major and minor Serratus anterior Deltoid provides shearing force, pushing humerus upward on the glenoid labrum at abduction
Rotator cuff muscles
Supraspinatus
Infraspinatus
Teres minor
Subscapularis
Protector muscles helping compress the humeral head into the glenoid
Impingement syndrome
Typical signs and symptoms
***Pain with overhead activites
Medial AC joint osteophyte formation commonly associated
Impingement Syndrome
Anatomy/structures involved
Biceps tendon Superior labrum Supraspinatus tendon Subacromial bursa Above all antero-lateral type
Subscapularis
Subcoracoid
Infraspinatus or teres minor
Posterior impingement type above
Impingement syndrome
Causes/etiology
***Over use
Degenerative changes
Inflammatory processes
Variant structure
Impingement syndrome co-exists with
Instability and excessive superior movement of the humeral head
Impingement evaluation
***Hawkins-Kennedy and Neer test for impingmeent assessment
***Relocation test for underlying accompanying instability
Impingement sign to rule in tendinitis or supra-spinatus overuse injuries
Hawkins-Kennedy test
Supraspinatus tendon jammed up against the anterior surface of the coraco-acromial ligament due to the narrowing of the subacromial space. Posterior pain implicates stretch of the teres minor and infraspinatus tendons
Indicates: local pain indicates supraspinatus tendinitis and impingement
Anterior pain = anterior impingement syndrome
Posterior pain = posterior impingement syndrome
Neer test
End range pain causes the greater tuberosity to jam up against the anterior inferior border of the acromion
Indicates impingement with overuse injury of the supraspinatus muscle or biceps tendon
Instability tests
Anterior apprehension with relocation
Jobe relocation test confirms the
Anterior instability of the GH joint
Painful arc test
Pain between 70-110 degrees is impingement syndrome with supraspinatus pathology
Pain worse with 160 or above is AC joint involvement
Shoulder impingement management protocols/goals
Care plan based on severity of symptoms - acute vs sub-acute vs chronic
Stability, progressive rehabilitation, stretching and strenghtening and modification of activity
Open chain v closed chain exercise, proprioceptive training
Chiro spinal adjustments
Chiro extremity adjustments
Modalitis - cryotherapy
2 week out assessment
Re-exam and re-eval
Prognosis/outcomes assessment
Traumatic instability
Presentation/signs/symptoms
***past history of shoulder dislocation
*** pain/weakness when arm placed overhead or in apprehension position of 90 degrees flexion coupled with external rotation and horizontal extension
Traumatic instability
Anatomy/structures involved
Gleno-humeral joint dislocation causes damage to the glenoid labrum and the humerus itself. The glenoid capsule will also incur damage along with teh intrinsic ligaments (coracohumeral and coracoacromial)
Traumatic instability
Pathophysiology/etiology
Acute/subacute anterior dislocation of the GH joint in 90-95% of cases. Posterior instability can be found in patient who chronically dislocate or those who suffer seizures
Clavicular fractures, muscle contusions and direct blows to the base of the neck can also be included as trauma
Traumatic instability evaluation
Apprehension test and it’s variants
** sulcus sign with L &S test
SUlcus sign with L & S test
A sulcus that appears on teh antero-lateral aspect indicates shoulder instability that is graded
\+1 = 1 cm \+2 = 1-2 cm \+3 = >3 cm
Labrum tears
Presentation
Presents with reported painful clunking and locking with specific movments. Loss of strength, decreased ROM and pain at night.
Sense of instability in the shoulder
Labrum tears
Anatomy and structures involved
Soft fibrous rim surrounding the head of the humerus where it articulates with the glenoid fossa. Stabilizes the joint and deepens the rim to add extra support. Important attachment site for several ligaments.
Labrum tears
Cause/etiology
**SLAP lesion
Acute trauma, blow or fall on outstretched arm. Sudden pulls such as lifting heavy object. Repetitisve motions such as weight lifting or throwing
**tears of the rim below the middle of the glenoid socket involving the inferior GH ligament are called Bankart lesions
***tears of the labrum often accompanying dislocation
SLAP lesions
Superior labrum anterior to posterior tear above the middle of the socket that involves the biceps tendon in some cases
Bankart lesions
Tears of the rim below the middle of the glenoid socket involving the inferior GH ligament
Tears of the labrum often accompany
Dislcoation
Labrum tears
Evaluation
Clunk test, O’Brien sign, anterior slide test and biceps load test to rule in a labrum tear
Rule out dislocation using apprehension, dugas tests
Speed, abbotts saunder and yergason tests to confirm any bicep tendon tears that might accompany a labrum tear. Can do apley adn codman if tolerable to R/O rotator cuff teras
Assess both spinal and extremities
Medical assessment for labrum tears includes
MRI
CT
Arhtroscopic surgery
Glenoid LAbrum testing
***O’Brien sign
O’Brien, anterior slide test for pain or determine snapping or clunking felt in the joint
