Nail hypertrophy after elective surgery on the little finger: a case report.

The authors present a case that developed acute painful nail hypertrophy of the ipsilateral four fingers which resembled finger clubbing after undergoing elective hand surgery on the little finger. The patient was diagnosed as having complex regional pain syndrome (CRPS), and the nail hypertrophy subsided gradually on pain control, and completely normalized one year after onset. Recognizing this phenomenon may help initiate early treatment for CRPS and avoid unnecessary antibiotic or antifungal medications for postoperative infection.
