Hypothenar Hammer Syndrome in a Postal Worker.

Area of Science:

• Vascular Surgery
• Occupational Medicine
• Hand Surgery

Background:

• Hypothenar hammer syndrome (HHS) is a rare condition affecting the ulnar artery and superficial palmar arch.
• It results from chronic, repetitive trauma to the palm, often seen in occupations involving blunt impact.
• Historically, HHS has been predominantly reported in males engaged in manual labor.

Observation:

• A 48-year-old female postal worker presented with symptoms consistent with HHS.
• Her occupational duties involved frequent use of a rubber stamper, a repetitive task causing blunt trauma to the hypothenar eminence.
• The repetitive compression likely damaged the ulnar artery against the hamate bone.

Findings:

• The patient's presentation suggests HHS can occur in females and be linked to non-traditional occupations.
• Repetitive use of tools like rubber stampers can induce vascular trauma similar to that seen in historically reported cases.
• This case expands the known demographic and occupational risk factors for hypothenar hammer syndrome.

Implications:

• Highlights the need to consider HHS in female patients with hand pain and vascular symptoms.
• Broadens the understanding of occupational risks for vascular trauma in the hand.
• Suggests that specific, repetitive occupational tasks, even those not involving heavy machinery, can lead to HHS.
