Ciprofloxacin-Induced Extensor Tendon Rupture in the Hand: A Case Report.

Case: An eighty-one-year-old man had begun taking ciprofloxacin one week prior to the sudden inability to extend the metacarpophalangeal joint of the ring finger of the dominant right hand. He presented to us three months after he initially noticed this finding.

Conclusion: Ciprofloxacin-induced tendon rupture appears to be possible in the extensor digitorum communis tendons of the hand. Our patient was managed operatively and had a good functional outcome.
