Abstract

Mallet finger is a very common finger disease. However, it is very rare for mallet fingers to occur simultaneously on three fingers of the same hand. We report a case of mallet fingers in a 46-year-old female who sustained a fall during a running race. She was injured on the middle, ring, and little fingers. Radiographically, bone fragments were observed on the dorsal side of the distal phalanx base on the middle, ring, and little fingers. She underwent surgical treatment using the extension block method. Extension lag was observed in the fingers other than the little finger (middle finger: 5°, ring finger: 10°). However, evaluation using Crawford's classification revealed good results. Thus, provide data on the treatment of multiple mallet fingers on the same hand.
