Contrasting shoulder 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.
      - Hills-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

Posterior dislocations: rare, caused by horizontal adduction and internal rotation

Symptoms
- Popping during movements
- Repeated dislocations or subluxations of the glenohumeral joint
Diagnosis
- Clinical presentation — Sulcus sign
- Special test — apprehension test (Gold Standard)
- X-ray
Medical management
- Acetaminophen or non-steroidal anti-inflammatory (NSAIDs)
- 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

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
- Acetaminophen or non-steroidal anti-inflammatory (NSAIDs)
- 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

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
- Acetaminophen or non-steroidal anti-inflammatory (NSAIDs)
- 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

- MRI
Medical management
- Acetaminophen or non-steroidal anti-inflammatory (NSAIDs)
- Surgery if indicated
Physical therapy intervention
- Determine the phase (acute vs subacute vs chronic) and make an appropriate selection of interventions based on the phase of healing
- 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

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
Medical management
- Acetaminophen or non-steroidal anti-inflammatory (NSAIDs)
Physical therapy management
- Determine the phase (acute vs subacute vs chronic) and make an appropriate selection of interventions based on the phase of healing

Bicipital tendonitis

  - Cases can be mechanical trapping (impingement) of the long head of the biceps between the acromion and the bicipital groove of the humerus

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, Yergason, and biceps load II test.
- MRI
Medical management
- Acetaminophen or non-steroidal anti-inflammatory (NSAIDs)
Physical therapy management
- Determine the phase (acute vs subacute vs chronic) and make an appropriate selection of interventions based on the phase of healing

Adhesive capsulitis

Distal humeral fracture
- Trauma causes a fracture at the distal humerus
  - Immediate attention must be given to whether a supracondylar fracture is due to the increased likelihood of neurovascular involvement
    - Radial nerve involvement associated with posterior type injuries may lead to damage of vascular structures, pulselessness, and/or paralysis
    - Ulnar nerve involvement associated with flexion type injuries may lead to paralysis and a loss of fine motor control in the hand
    - In children, it can cause malunion due to growth plate involvement
  - Lateral epicondyle fractures will require internal fixation (rod and screws implanted in arm) for adults, percutaneous removal pins for non-skeletally mature fractures, for proper alignment
