Abstract

Mallet fracture is an avulsion of the extensor tendon and fracture of the dorsal rim of the articular surface of distal phalanx at the same time. If a part of the mallet fracture is angled or rotated to such a degree that prevents full anatomic reduction, malunion and deformities may occur as a result. The objective of this study was to describe a new surgical technique to provide derotation of the mallet fracture. A 22G or 21G needle is used like a joystick to reduce the mallet fracture with small, gentle movements. The extension block pinning technique described by Ishiguro was applied after proper alignment had been achieved. Bony union was achieved for all patients 6 weeks later. Derotation of type 2 and 3 mallet pieces with closed reduction to prevent surgical failure is simple but effective. (C) 2018 SFCM. Published by Elsevier Masson SAS. All rights reserved.
