Shoulder soft tissue conditions
- Glenohumeral dislocations and instability
- Dislocations of the glenohumeral joint caused by traumatic or atraumatic reasons
- Trauma is due to direct injury, most commonly a fall on an outstretched hand (FOOSH) mechanism of injury
- Atraumatic can be due to repetitive injury, causing hypermobility
- Types of dislocations:
- Anterior-inferior dislocations: Most common type (95%). Mechanism is a combination of motions including: excessive horizontal abduction, abduction, external (lateral) rotation, and extension/hyperextension of the upper extremity.
- If traumatic can lead to: Disruption anterior glenohumeral/capsular ligament, subscapularis, and anterior/inferior glenoid labrum
- Sulcus sign: a depression or groove appears between the acromion and the humeral head; this finding indicates inferior or multidirectional instability rather than being specific to anterior dislocation.
- Hill-Sachs lesion: compression fracture of the posterior humeral head
- Bankart lesion: avulsion of the anterior-inferior glenoid labrum
- Axillary nerve injury: numbness, tingling, and weakness in the deltoid
- If traumatic can lead to: Disruption anterior glenohumeral/capsular ligament, subscapularis, and anterior/inferior glenoid labrum
- Posterior dislocations: rare, caused by horizontal adduction and internal rotation
- Anterior-inferior dislocations: Most common type (95%). Mechanism is a combination of motions including: excessive horizontal abduction, abduction, external (lateral) rotation, and extension/hyperextension of the upper extremity.
- Dislocations of the glenohumeral joint caused by traumatic or atraumatic reasons
-
Symptoms
- Popping during movements
- Repeated dislocations or subluxations of the glenohumeral joint
-
Diagnosis
- Clinical presentation - apprehension test positive for anterior instability; sulcus sign positive for inferior instability
- Special test - apprehension test (highly specific for anterior instability)
- X-ray
-
Medical management
- Surgery as indicated
-
Physical therapy interventions
- Strengthening the capsule and muscles directly connected to prevent further dislocations
- Functional training
- Avoidance of apprehension position
- Surgical protocols if indicated
- With anticipated return to function in 3-4 months
-
Labral tears
- Tear in the cartilage ring that surrounds the shoulder joint; divided into above the middle of the socket and below the middle of the socket
- Above the middle of the socket is called a SLAP (superior labral anterior-posterior) tear; can also involve the biceps tendon
- Below the middle of the socket is called a Bankart lesion; it can also involve an avulsion fracture of the anterior/inferior lip of the glenoid (bony Bankart)
- Labral tears are associated with traumatic injury or repetitive shoulder dislocations
- Tear in the cartilage ring that surrounds the shoulder joint; divided into above the middle of the socket and below the middle of the socket
-
Symptoms:
- Pain increased with overhead movement or behind the back
- Shoulder weakness
- Shoulder instability/dislocation
- Pain with resisted flexion of the biceps
- Tenderness over the anterior shoulder
-
Diagnosis
- Clinical presentation
- MRI
- Arthroscopic surgery - gold standard for diagnosis
-
Medical interventions
- Surgery if indicated
-
Physical therapy interventions
- Focus on return to function without pain
- Restoration of muscle imbalances
- Address underlying causes of labral tears
- Surgical protocols if indicated
- With anticipated return to function in 3-4 months
-
Rotator cuff tendonitis
- Caused by mechanical impingement of the distal attachment of the rotator cuff, causing inflammation of the tendons
- Increased risk for development of tendonitis due to poor vascularity at attachment sites
- Caused by mechanical impingement of the distal attachment of the rotator cuff, causing inflammation of the tendons
-
Impingement syndrome
- Impingement (entrapment) of the rotator cuff tendon against the acromion due to mechanical repetition
-
Symptoms
- Pain in the anterior and superior aspect of the shoulder
- Pain and weakness that worsen with overhead movements, such as reaching, throwing, or lifting objects
- Pain that may radiate down the arm
- Pain that is worse at night
-
Diagnosis and pain referral location
- Clinical presentation
- Special tests
- Hawkins-Kennedy - subacromial region
- Neer’s superior coracoacromial region
- Painful arc
- Shoulder pain that occurs when abducting an arm between 70 and 120 degrees.
- MRI
-
Medical management
- Surgery if indicated
-
Physical therapy intervention
- Avoidance of shoulder elevation greater than 90 degrees to avoid subacromial compression - acute phase
- Postural re-education - improve forward head, rounded shoulders, and kyphotic posture (upper cross syndrome)
- Correction of muscle imbalances
- Improve joint mobility
- Return to previous functional status
- Surgical decompression if indicated
-
Rotator cuff tear/damage
- Causes acute tear from a fall on an outstretched hand (FOOSH), sudden heavy lifting, or the shoulder in an awkward position
- Partial and degenerative damage from an increased risk for the development of tendonitis due to poor vascularity at attachment sites
-
Symptoms
- Pain when raising or lowering the arm
- Pain when reaching behind your back
- Pain that worsens after lying down on the affected side
- Pain that is worse at night
-
Diagnosis
- Clinical presentation
- Special tests - empty can test, drop arm test, manual muscle testing of infraspinatus and supraspinatus
- MRI
-
Medical management
- Surgery if indicated
-
Physical therapy intervention
- Surgical protocols if indicated
-
Subacromial/subdeltoid bursitis
- Subacromial and subdeltoid bursae become inflamed (close relationship with rotator cuff tendonitis)
- The bursa becomes trapped (impinged) beneath the acromion arch
- Subacromial and subdeltoid bursae become inflamed (close relationship with rotator cuff tendonitis)
-
Symptoms
- Pain may worsen with overhead movements, such as reaching for objects or lifting the arm.
- The shoulder may be tender to the touch, especially around the acromion process.
- The bursa may become inflamed and swollen, causing a visible bulge or lump in the shoulder.
- The shoulder may feel stiff and difficult to move
- When moving the shoulder, there may be clicking or popping sounds as the bursa rubs against the acromion bone.
- Empty end-feel joints’ passive movement stops due to the patient’s pain, not because of a physical blockage
-
Diagnosis:
- Clinical examination - ruling in and out other diagnoses based on symptomatology, as well as assessment of range of motion and muscle strength
-
Bicipital tendonitis
- Inflammation of the long head of the biceps
- Cases can be mechanical trapping (impingement) of the long head of the biceps between the acromion and the bicipital groove of the humerus
- Inflammation of the long head of the biceps
-
Symptoms
- Sharp, throbbing, or dull pain in the front of the shoulder that may radiate down the upper arm - pain worsens with overhead movements, such as reaching, lifting, or throwing.
- Localized tenderness over the biceps tendon, particularly where it passes over the shoulder joint.
- A feeling or sound of snapping or popping in the shoulder when moving the arm.
- Weakness in the biceps muscle, making it difficult to lift or bend the arm.
-
Diagnosis
- Clinical presentation, positive Speed’s and Yergason’s tests.
- MRI
-
Adhesive capsulitis
- Restriction in shoulder motion due to inflammation of the joint capsule
- Restrictions are in external rotation (greatest), then abduction, then internal rotation (capsular pattern of the shoulder)
- Reason for diagnosis can be repetitive motion, diabetes, cardiovascular disease, or thyroid disease
- Restriction in shoulder motion due to inflammation of the joint capsule
-
Symptoms
- Restriction in external rotation, abduction, and internal rotation, causing functional deficits
-
Diagnosis
- Clinical presentation
- Functional limitations
-
Medical management
- Management of diabetes, cardiovascular, or thyroid disease if applicable
-
Physical therapy management
- Improve joint mobility in the capsular pattern
- Return to prior functional status
- Improve muscle imbalances
