Summary
Hypothenar hammer syndrome (HHS) results from chronic trauma, often from occupational use of the hand as a tool. Recognizing this link is crucial for diagnosing and managing this vascular condition.
Area of Science:
- Vascular Surgery
- Occupational Medicine
- Hand Surgery
Background:
- Hypothenar hammer syndrome (HHS) is an underrecognized condition caused by repetitive mechanical trauma to the hypothenar eminence.
- This trauma can lead to intimal damage of the ulnar artery, potentially causing thrombosis or aneurysms near the hamate bone.
Purpose of the Study:
- To present cases of HHS and investigate the relationship between occupational or sport activities and the syndrome.
- To outline diagnostic methods and therapeutic approaches for HHS.
Main Methods:
- Case series of six patients diagnosed with HHS.
- Clinical examination, non-invasive vascular studies (Doppler, plethysmography), capillaroscopy, laboratory tests, and hand arteriography were utilized.
- Evaluation of patient activities, focusing on occupational and sport-related causes.
Main Results:
- Four of the six patients had occupational activities as the likely cause of HHS.
- Two patients' HHS was attributed to sports activities.
- Clinical signs indicated compromised blood flow in the ulnar artery's supply territory.
Conclusions:
- A causal link between occupational exposure and the development of HHS is established.
- HHS should be recognized as an occupational disease when related to work activities.
- Avoiding the causative activity is the primary therapeutic strategy.
