|December 1, 1984
Summary
Ulnar artery thrombosis, also known as hypothenar hammer syndrome, results from repeated hand trauma. Early screening with the Allen test can help prevent the need for vascular surgery.
Area of Science:
- Vascular Surgery
- Hand Surgery
- Occupational Health
Background:
- Ulnar artery trauma, first described in 1934, is now recognized as ulnar artery thrombosis, hypothenar hammer syndrome, or post-traumatic digital ischemia.
- This condition arises from repetitive trauma to the hypothenar eminence, often due to using the hand as a hammer.
Purpose of the Study:
- To highlight the importance of screening for ulnar artery thrombosis in individuals with a history of hand trauma.
- To emphasize the role of the Allen test in early detection.
Main Methods:
- Screening individuals with a history of trauma to the hypothenar eminence.
- Utilizing the Allen test for quick and easy assessment of vascular insufficiency.
Main Results:
- The Allen test can effectively screen for ulnar artery thrombosis.
- Early detection is crucial for managing the condition.
Conclusions:
- Screening for ulnar artery thrombosis using the Allen test is recommended for at-risk individuals.
- Prompt identification and cessation of trauma can potentially prevent the need for reconstructive vascular surgery.
