Summary
Distal biceps tendon (DBT) tears are common in middle-aged men following eccentric elbow contractions. Early diagnosis via clinical suspicion and specific tests aids timely management of these injuries.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Anatomy
Background:
- Distal biceps tendon (DBT) tears frequently affect middle-aged men.
- These injuries typically result from sudden, forceful eccentric contraction of a flexed elbow.
Purpose of the Study:
- To emphasize the importance of understanding risk factors, mechanisms, and pathophysiology for accurate diagnosis.
- To highlight diagnostic methods and treatment options for distal biceps tendon tears.
Main Methods:
- Clinical suspicion and physical examination are key.
- Specialized tests include the hook test, passive forearm pronation test, biceps crease interval test, and bicipital aponeurosis flex test.
Main Results:
- These diagnostic maneuvers facilitate rapid and accurate identification of DBT tears.
- Effective management strategies are guided by precise diagnosis.
Conclusions:
- Timely diagnosis of distal biceps tendon tears is crucial.
- Treatment varies based on injury extent (complete/incomplete) and chronicity (acute/chronic), including nonoperative care, repair, or reconstruction.
