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.
ABSTRACT
A 57-year-old man fell from a height of 6 m and injured his right foot. Imaging studies showed an uncommon injury; naviculocuneiform and calcaneocuboid joint fracture dislocations. He underwent a temporary fixation with Kirschner wires (K-wires), and the injured foot was immobilized with a below-knee splint. Weight-bearing was started gradually. The K-wires were removed at 8 weeks. Full weight-bearing was achieved 14 weeks after the operation. At 19 weeks, he returned to his carpentry job. At 1 year, he had no marked limitation of daily activities. Early recognition of these injuries is required to prevent persistent foot pain and long-term dysfunction.
