Shoulder Conditions Flashcards
Anterior Glenohumeral Dislocation/Subluxation
- 95% of dislocations occur in anterior-inferior
- Occurs when ABD UE is forcefully ER causing a tear of the inferior glenohumeral ligament, anterior capsule, and occasionally glenoid labrum
Posterior Glenohumeral Dislocation/subluxation
- posterior dislocations are rare and occur with multidirectional laxity of GH joint
- Occurs w. horizontal ADD and IR of glenohumeral jt
- Complications may include
- compression fracture of posterior humeral head (Hill-Sachs Lesion)
- tearing of superior glenoid labrum from anterior (front) to posterior (back) aka SLAP lesion.
- an avulsion of antero inferior capsule and ligaments associated w. glenoid rim (bankarts lesion)
- **bruising of axillary nerve **
Glenohumeral Subluxation/Dislocation: Dx
plain film imaging, CT scan, MRI
Glenohumeral Subluxation/Dislocation: PT
- intervention varies depending on surgery
- address biomechanical faults caused by joint restriction
- restoration of normal shoulder mechanics via strengthening/endurance that focuses on scapulothoracic, glenohumeral, and muscular re-ed
Glenohumeral Instability: Types and Characteristics
- Traumatic: young throwing athletes
- Atraumatic: individuals w/ congenitally loose connective tissue around the shoulder
- Characteristics:
- popping/clicking and repeated sublux/dislocation of GH
- Unstable injuries require surgery to reattach labrum to glenoid
- **Bankharts lesion requires surgery
Glenohumeral Instability: Dx
- clinical exam comparing results of patient history with AROM, PROM. resistive tests and palpatation
- MRI arthrograms are also very effective
Glenohumeral Instability: PT
- emphasize RTF w/o pain
- functional training and restoration of ms imb
- address biomechanical faults
- Post surgery:
- should kept in sling for 3-4 weeks
- after 6 weeks: more sport specific training
- Full fitness may take 3-4 months
Labral Tears: Etiology
- Inferior or Superior, SLAP or Bankharts
- Often occur with other shoulder pathology including dislocations
Labral Tears: Signs and Symptoms
- shoulder p! that cannot be localized to a specific point
- p! made worse by OH activities or when arm is behind back
- weakness
- instability of the shoulder
- p! on resisted flexion of the bicep (against resist elbow flex)
- tenderness on the front of the shoulder
Labral Tears: Diagnosis
- clinical exam by comparing results of AROM, PROM, resist tests, and palpation.
- MRI arthrograms
- Arthroscopic surgery = GOLD STANDARD
Labral Tears: PT
- return to function w/o pain
- funx training and restoration of ms imbalance
- address underlying causes (instability)
- address biomechanical faults
- Post op
- sling 3-4 weeks
- after 6 weeks - sport specific
- full recovery 3-4 months
Thoracic Outlet Syndrome:
- compression of the neurovascular bundle
- brachial plexus
- subclavian artery/vein
- vagus/phrenic nerves
- sympathetic trunk
- compression occurs when size/shape of TO is altered
- Common areas of compression
- superior thoracic outlet
- scalene triangle
- between clavicle and 1st rib
- between pec min and thoracic wall
Thoracic Outlet Syndrome: Dx
- plain film imaging to identify bony abnorm
- MRI identify soft tissue
- Electrodiagnostic test - nerve dysfunc
- CLinical exam
- adsons
- roos test
- wright test
- costoclavicular test
Thoracic Outlet Syndrome: PT
- **Surgery may be required to remove cervical rib or release ant/middle scalene
- postural re-education
- functional training and restoration of ms imb
- biomechanical faults
- manipulations (typically 1st rib articulation) to diminish pain and soft tissue guarding
Acromioclavicular and Sternoclavicular Joint Disorders:
- MOI: fall on shoulder w/ UE ADD or a collision with another individual during sporting event
- Degree of injury graded I-III (IV-VI)
- Acute phase:
- UE positioned in neutral w. use of sling
- avoid shoulder elevation
Acromioclavicular and Sternoclavicular Joint Disorders: Diagnosis
plain film
Acromioclavicular and Sternoclavicular Joint Disorders: PT
- surgical repair is rare second to tendency for AC joint degeneration afterward
- emphasize RTF w/o pain
- functional training and muscle imb
- MT to AC and SC joints and surrounding connective tissue such as soft tissue massage/ joint oscillations etc
Subacromial/Subdeltoid Bursitis
both bursae have a close relationship to rotator cuff tendons making them susceptible to overuse and impinged below acromial arch
Subacromial/Subdeltoid Bursitis Dx
clinical examination - differentiate from contractile condition by comparing results of AROM, PROM and resistive tests
Rotator Cuff Tendonosis/Tendonopathy:
RTC tendons are susceptible to tendonitis due to relatively poor blood supply near insertion of ms
- results from mechanical impingement of the distal attachment of the RC on the anterior acromion and/or coracoacromial ligament w/ rep OH activities
Rotator Cuff Tendonosis/Tendonopathy: Dx
- MRI but not always sensitive enough
- Clinical Exam
- supraspinatus test
- neer’s impingement
Impingement Syndrome:
- Soft tissue inflam of the shoulder from impinge. against** acromion w/ rep OH AROM **
Impingement Syndrome: Dx
- Arthrogram or MRI
- Clinical exam
- neers
- supraspinatus
- drop arm test
Impingement Syndrome: PT
- surgical repair - avoid shoulder elevation greater than 90
- restoration of posture
- correction of ms imbalance
- biomechanical fault correction
