Operative repair of mallet fracture is a technically difficult operation because of fracture of fragment and the difficulty in visualizing the articular congruity. The problems with these methods include soft tissue scar formation and subsequent joint stiffness. With regard to the relationship between the position of the distal joint and the fragment, the fragment is pushed out on the dorsal side in a hyperextensive position of the DIP joint, whereas the DIP joint in palmar flexion provides congruity of the articular surface, yielding enough space for the fragrnent. Utilizing these phenomena, Ishiguro devised a new method for closed reduction by extension block From January 1993 to January 1996, twenty cases of mallet fingers with displaced large fracture fragment and/or subluxed distal phalanx were treated by closed reduction using extension-block Kirschner wire. The follow-up evaluation took place after a mean of 6 months. The results according to Crawfords criteria were ten excellent, five good and five fair. This technique is simple, and easier than other techniques for reduction of mallet fractures, and is associated with low morbidity. The operative procedure is easy, not causing much stress and leaving no scar because the Kirschner wire is inserted transcutaneously.
