Comminuted intra-articular distal radius fractures rarely fail in one plane. Dorsal fragments tilt backward, central fragments sink into the metaphysis, and a single row of parallel screws can only restrain what lies directly in its line. The more displaced fragments a fracture contains, the more a single-plane construct leaves to chance.
The Crosslock configuration addresses this by crossing the distal locking screws in two planes through the same plate head. Fragments are pinned between intersecting screw paths rather than resting on a single row, giving the volar approach a way to control dorsal-sided pieces without a second incision. Fragment assessment and the choice between single-plane and crosslock fixation remain with the operating surgeon.
