Biceps Tendiopathy and Tendon Rupture Flashcards
True or False
Biceps tendon ruptures can occur at both proximal and distal locations
True
Biceps tendon injuries appear to occur more often among patients who do what?
engage in frequent pulling, lifting, reaching, or throwing for work or recreation
Rock climbers and weight lifters for example
Where does the long head of the biceps brachii originate?
at the superior glenoid tubercle, where it contributes to the formation of the glenoid labrum
Where does the short head of the biceps brachii originate?
at the coracoid process
It is believed that ____ biceps tendon injury is not due to a unique mechanism but rather results from general shoulder pathology, such as impingement or instability
proximal
What contributes to tendon injury within the bicipital groove, below the acromion, or at the labral attachment?
Dysfunction of the rotator cuff and scapular stabilizers
The frequency of biceps tendon tears ____ with age
increases
What is rupture of the proximal biceps tendon associated with?
RC tears
What does the acute mechanism of distal biceps tendon rupture often involve?
a sudden traumatic extension of a flexed elbow when the biceps muscle is fully contracted
Other than a RC tear, what are a few differential diagnoses for biceps tendinopathy?
- Glenohumeral arthritis
- AC pathology
- Pectoralis minor strain
- Referred cervical or brachial plexus pain
- Diseases of the chest (acute coronary syndrome)
- Diseases of the abdomen (gallbladder disease)
Where is pain from biceps tendinopathy typically?
Focused in the anterior shoulder with radiation distally over the biceps muscle
What movements aggravate biceps tendinopathy?
lifting, pulling, and repetitive overhead activities
What are some other patient complaints associated with biceps tendinopathy?
A painful arc of motion associated with a click and pain that worsens at night
When do acute tendon rupture usually occur?
During a specific traumatic event that causes sudden pain, a “pop,” ecchymosis, and swelling
In what type of patient is biceps tendon rupture difficult to diagnose and why?
- In obese populations, because the classic “Popeye” deformity may be obscured by adipose tissue
- Also in some elderly patients.
