  • strengthening
  • mobilization after acute pain subsides.

Chiro adjustments to restore functional proprioception and alignment.

46
Q

Management of severe Labrum tear.

A

Referral to Orthopaedic surgeon for assessment -

Most severe tears will require surgery for repair.

47
Q

Signs/Symptoms and presentation:
Usually asymptomatic.

Pain is felt when there is sudden traction or pulling on the
arm.
Supporting the arm provides relief.

Patient reports fatigue and discomfort when working overhead rather than actual pain.

Condition???

A

48
Q

Patient presenting with Non-traumatic Instability/looseness are BORN THAT WAY! And are asymptomatic unless:

49
Q

Non-traumatic Instability/looseness - Evaluation

A
  • L&S tests
  • Apprehension test (if accompanied by Impingement)
  • Pain is reduced by the relocation (Jobe test)
50

A

Final phase

55
Q

Although the cause of adhesive capsulitis remains unknown, it is more commonly seen in patients with:

A

Diabetes, thyroid pathologies, and COPD.

56
Q

Evaluation of adhesive capsulitis:

IF the patient does not improve at all we suspect:

A
  • Positive Mazion Shoulder Maneuver (most patients present in the stiffening stage or stage 2)

-Restriction and pain are reliable indicators especially in abduction and
external rotation.

** If the patient does not improve at all, a bony blockage is suspected due to
possible osteoarthritis.

57
Q

Management for adhesive capsulitis:

A
  • Cryotherapy
  • Extremity adjustment to improve ROM
  • E-stim and TENS, Ultrasound (in stiffening stage.)
  • Passive and active therapy with contraction and ROM while alternating patterns
58
Q

Presentation:

Typically following an acute trauma such as heavy lifting, a fall or high impact injury. Older patients might not recall an event.
Pain and or weakness is experienced while lifting the arm or performing overhead activities.

Condition???

A

Rotator Cuff Tears

59
Q

Rotator Cuff Tears are M.C. Associated with tears of:

A

Supraspinatus

60
Q

Etiology of Rotator Cuff Tear:

A

Trauma, can occur secondary to chronic degenerative changes

in the tendinous attachments.

61
Q

Rotator cuff tears assessment:

A

Supraspinatus: weakness with Empty Can test or Codman’s drop arm (unable to perform) and a positive Apley test.

Subscapularis: Lift-off test weakness.

62
Q

What does Rotator Cuff Tear looks like on a radiograph?

A

Superior head migration on AP view.

63
Q

Management of Rotator Cuff Tears

A
  • Rehab gradually with isometrics then progressing to strengthening.
  • Rotator-cuff full thickness tears might need surgical repair.
64
Q

Presentation:
Trauma/fall/high impact injury on an outstretched arm or on top of the shoulder type onset. Very common in athletes such as football or rugby players. Pain, tenderness and swelling over the AC joint.

A

AC Joint Seperation

65
Q

Which grade of AC separation is associated with: some tearing of the Acromio-Clavicular ligament without instability.

A

Grade I

66
Q

Which grade of AC Joint Separation is associated with: Rupture of AC ligament

A

Grade II

67
Q

Which Grade of AC Joint Separation is associated with: torn AC ligament with a tear of the Coraco-Clavicular (conoid and trapezoid) ligament. Both Grade II and III are considered unstable.

A

Grade III

68
Q

Which grade of AC Joint Separation is associated with: the clavicle is pushed posterior to the AC joint, fairly unusual in presentation.

A

Grade IV

69
Q

Which AC Joint Separation is associated with: an exaggerated grade III with the muscles above the AC joint punctured by the clavicle causing a significant bump over the injury site.

A

Grade V

70

Which AC Joint Separation is associated with: fairly rare, this type of injury sees the clavicle pushed or forced inferior where it becomes lodged below the corocoid.

A

Grade VI

71
Q

Causes/Etiology of AC Joint separation.

A

Trauma/fall/high impact sports injury that tears partially or completely the AC or Coraco-Clavicular ligaments.

72
Q

Evaluation of AC Joint Separation

A

Positive: O’Brien Sign

X-Ray to rule out distal clavicular fracture and determine severity of injury. **Weighted and non-weighted bilat. View would be ordered.

More than 1.3 cm widening of the Coraco- Clavicular space would indicate a Grade III separation.

73
Q

Management of AC Joint Separation

A

-Support with a Kinney-Howard sling for a short period. Mild Isometrics followed by Isotonics.

74
Q

Presentation:
-Can be secondary to AC trauma or heavy weight lifting regimens.

-Typically a weight lifter will present with diffuse pain felt while bench-
pressing, clean and jerking or dipping. Pain on shoulder abduction
beyond 90 degrees.

Condition???

A

Osteolysis of the Distal Clavicle.

75
Q

What is the cause/etiology of Osteolysis of the Distal Clavicle?

A

Trauma/repetitive compression forces and heavy lifting that cause
resorption of the distal end of the clavicle.

76
Q

Why is a Zanca view or AC spot shot and a thorough history is crucial to help rule out differential diagnosis of Osteolysis of the Distal Clavicle?

A

B/C most orthopedic tests are unremarkable.

77
Q

Management of Osteolysis of the Distal Clavicle.

A
  • Modification of exercises with some rest recommended.

- Chiropractic spinal and extremity evaluation.

78
Q

Presentation:
Severe shoulder pain increasing with any shoulder movement. Patients
have a supportive posture, holding the arm to their sides to avoid
movement.

Condition???

A

Acute Calcification Bursitis and Tendinitis

79
Q

Cause/etiology of Acute Calcification Bursitis and Tendinitis

A
  • Following trauma or of insidious onset.
  • Bursitis pain occurs often due to resorption of calcium deposition.

This is typically an inflammatory phase
and is very painful. Direct trauma or injury associated with cuff rupture is
considered another common cause.

80
Q

Evaluation of Acute Calcification Bursitis and Tendinitis.

A
  • Dawnbarn (+ with Sub-acromial bursitis)
  • Abbott Saunders, speed and Yeargason (+ for bicipital tendinitis)
  • Apley test (+ degenerative tendinitis)
  • Patte test (Hornblower sign) (+ with infraspinatus or Teres Minor tendinopathy)
  • Lift off test (+ subscapularis tendinopathy)
81
Q

Management of Acute Calcific Bursitis and Tendinitis

A
  • Pulsed Ultrasound to resorb calcific deposits for short term therapy
  • Chiropractic spinal and extremity adjustments to assist with recuperative healing and functional proprioception.
  • Cryotherapy is recommended to reduce swelling and manage pain.
  • In acute and inflammatory stages, referral to a medical practitioner is recommended due to severe pain.
82
Q

Little Leaguer’s shoulder is associated with Triangular metaphysical avulsion fracture, also known as:

A

Salter-Harris Type 2

84

Etiology of Little Leaguer’s shoulder.

A

Excessive rotational stresses on the growth plate of the proximal
humerus from pitchers who over pitch or pitch too frequently (Salter-
Harris type 1). Type 2 is less common.
