Shoulder and Upper Quadrant Flashcards
What are the most common cancers that metastasize to the shoulder, and why is past medical history important in shoulder pain screening?
- Breast and lung cancer are most common.
- Past medical history is crucial as it helps identify potential systemic causes of shoulder pain.
Explain the significance of multi-segmental innervation and diaphragmatic irritation in the context of shoulder pain.
- Multi-segmental innervation allows pain to be referred to the shoulder from other body parts
- Diaphragmatic irritation can cause sharp pain in specific areas due to shared innervation at C3-C5.
What are the key risk factors associated with shoulder pain that suggest a cardiac origin?
Risk factors include:
- age > 50
- postmenopausal female
- family history of heart disease
- history of hypertension or diabetes
When should adhesive capsulitis be considered in a patient with shoulder pain?
It should be considered in older adults or patients with risk factors like Graves’ disease or diabetes mellitus.
Describe how shoulder pain can be differentiated as being of visceral origin rather than musculoskeletal.
Visceral pain may increase with…
- shoulder movements
- have no direct mechanical cause
- can be accompanied by systemic symptoms like GI issues or diaphoresis
Which organs can refer pain to the left shoulder, and what symptoms might accompany this pain?
- heart =
- spleen =
- pancreas =
- left lung =
- kidney / adrenal gland =
What specific features suggest pulmonary causes for shoulder pain?
- sharp, localized pain aggravated by breathing
- relief by lying on the affected side
- symptoms like cough or pleuritic pain
What screening questions should you ask to rule out cardiovascular causes of shoulder pain?
- “Does your mouth, jaw, or teeth hurt when your shoulder is bothering you?”
- “Does nitroglycerin relieve your shoulder pain?”
Why is it important to check vital signs when assessing shoulder pain for a potential cardiovascular origin?
Changes in vital signs may indicate systemic conditions like heart disease or pericarditis, which can cause shoulder pain.
What are some of the classic signs and symptoms of diaphragmatic irritation referring to the shoulder?
Pain in the upper trapezius, neck, or supraclavicular fossa from central irritation, or ipsilateral pain from peripheral irritation.
How can gastrointestinal issues like gallbladder disease refer pain to the shoulder?
GI pain may present in the right shoulder due to diaphragmatic irritation, with symptoms like nausea, vomiting, or pain related to meals.
When assessing for renal or urinary causes of shoulder pain, what key factors should be considered?
Look for ipsilateral shoulder and flank pain, elevated temp, changes in urinary habits, and a history of kidney infections or stones.
What distinguishes neuromuscular or neurologic causes of shoulder pain, like thoracic outlet syndrome?
Thoracic outlet syndrome is characterized by neurogenic pain, possibly radiating to the neck, axilla, and ulnar nerve distribution.
What is Kehr’s sign, and what does its presence indicate in a patient with shoulder pain?
Kehr’s sign is referred to the left shoulder on gentle palpation of the abdomen when the patient is lying down with legs elevated. It is classically associated with splenic rupture.
- Can be due to diaphragmatic irritation, often associated with splenic injury or post-laparoscopic procedures.
Describe how Complex Regional Pain Syndrome (CRPS) may present in the upper extremity.
CRPS presents with chronic pain disproportionate to the injury, sensory, vasomotor, sudomotor changes, and possible muscle atrophy.
What systemic signs might indicate an infectious cause of shoulder pain?
Constitutional symptoms like fever, malaise, or localized redness and warmth around the shoulder joint.
Which screening questions should be asked for potential GI causes of shoulder pain?
- “Have you had any nausea, vomiting, difficulty swallowing, loss of appetite, or heartburn since your shoulder started hurting?”
What role do postural changes play in differentiating pulmonary causes of shoulder pain?
Pulmonary pain typically doesn’t worsen with postural changes unless associated with pleuritic components.
What screening questions help rule out a cardiovascular cause in a patient with known heart disease?
“Does your shoulder pain decrease when you take nitroglycerin or lean forward?”
What does the Budapest Criteria help diagnose, and what are the key signs?
It helps diagnose CRPS, requiring three out of four categories:
- sensory
- vasomotor
- sudomotor, and
- motor changes
What is the significance of pain that worsens 2-4 hours after taking NSAIDs in the context of shoulder pain?
It may indicate a GI cause, such as ulceration or other irritation exacerbated by NSAID use.
Why is it important to screen joints above and below the shoulder when assessing pain?
Pain in the shoulder could be referred from nearby joints or structures like the neck, making a thorough examination necessary.
What systemic red flags should raise suspicion of an infectious cause of shoulder pain?
History of IV drug use, recent trauma, diabetes, or age >80 years with insidious onset of shoulder pain.
Which factors would make you suspect a neuromuscular cause of shoulder pain over a visceral one?
Presence of postural issues, occupational risks, or history of repetitive overhead activities.
