Comminuted Dorsal Ulnar Fragment in Distal Radius Fractures Treated Using the Integrated Compression Screw With a Mini-Plate

Stabilization for displaced dorsoulnar fragments in distal radius fractures is challenging to treat with conventional volar locking plates alone. The integrated compression screw combined with a volar locking plate has been introduced as an additional tool to stabilize the dorsoulnar fragment and has been reported to work effectively. However, the compression screw is unable to stabilize a comminuted dorsal ulnar fragment; therefore, it is necessary to consider using an additional dorsal plate. We have developed a modified surgical technique to stabilize a comminuted dorsal intra-articular fragment by combining the integrated compression screw with a mini-plate as a washer or a buttress.
