Treatment of Multiple Coronal Fractures in the Proximal Carpal Row with a Dorsal Distraction Bridge Plate: A Case Report

Abstract

Lunate coronal fracture is a rare injury, associated with impact along the capitate and lunate axis; neutralization of this axial force is important for satisfactory patient outcomes. This report presents a case of a 51-year-old man with a lunate coronal fracture associated with coronal fractures in the proximal carpal bones and volar and proximal dislocation of the distal carpal row. Open reduction and internal fixation with a dorsal distraction bridge plate were performed. Solid bony union was achieved at the fracture site and the patient resumed full activities without difficulty. Use of distraction bridge plate fixation can support treating this type of injury, in particular, in cases where the lunate fracture is difficult to treat with conventional osteosynthesis techniques; the presented approach provides good short-term results.
