AI Article Synopsis

  • A bony mallet thumb is a rare injury, and in this case, it occurred in an 82-year-old man after a fall, leading to a specific fracture in the thumb's distal phalanx.
  • Initial conservative treatment was attempted, but surgery became necessary due to the redislocation of the bone fragment.
  • The Ishiguro extension block technique, commonly used for bony mallet fingers, was successfully applied in this case, resulting in satisfactory thumb function three months later.

Article Abstract

A bony mallet thumb is an extremely rare injury. An 82-year-old man fell from a standing height and injured his right thumb. Imaging examinations revealed a rare intra-articular fracture at the dorsal side of the base of the distal phalanx of the thumb called the bony mallet thumb. Conservative treatment was adopted initially; however, surgery was deemed necessary because of the redislocation of the bone fragment. Thus, the Ishiguro extension block technique was used, and three months later, satisfactory thumb function was achieved. The Ishiguro technique is a relatively simple procedure often performed for bony mallet fingers. The current case indicated that it can also be used to treat cases of bony mallet thumbs successfully.
