Summarizing Shoulder Conditions Flashcards
What is the progressive non-inflammatory disease characterized by degenerative changes in the glenohumeral joint?
Glenohumeral joint osteoarthritis
What is the chronic inflammatory disorder of the glenohumeral joint capsule and synovial lining in which initial inflammation is followed by reactive joint capsule fibrosis?
Adhesive capsulitis
What is the compression of tissue in the subacromial space?
Impingement syndrome
Which tissues may be compressed by impingement syndrome?
- Subacromial bursa (bursitis)
- Supraspinatus tendon (tendinopathy)
- Long head biceps (tendinopathy)
What are the muscles affected by rotator cuff tear in order or prevalence?
- Supraspinatus tendon
- Infraspinatus tendon
- Subscapularis tendon
- Teres minor tendon (rare)
What is the progressive non-inflammatory disease characterized by degenerative changes in the acromioclavicular joint?
Acromioclavicular joint osteoarthritis
What is the etiology of primary adhesive capsulitis?
Idiopathic
What is the etiology of secondary adhesive capsulitis?
Another condition:
- Systemic disorders
- Shoulder disorders
- Non-shoulder disorders
What are some systemic disorders that may cause secondary adhesive capsulitis?
- Diabetes mellitus
- Thyroid disease
- Autoimmune disease
The supraspinatus tendon has tendinopathy due to compression in the subacromial space, what term describes this condition?
Impingement syndrome
What are some etiologies of impingement syndrome?

- Tight posterior glenohumeral joint capsule
- Tight inferior glenohumeral joint capsule
- Decreased upward rotation of scapula
The following could all lead to what condition?
- Strength imbalance
- Tight posterior glenohumeral joint capsule
- Tight inferior glenohumeral joint capsule
- Decreased upward rotation of scapula
