Multiple Cantilever K-Wiring Technique for Severely Comminuted Intra-articular Fragments - A Novel Surgical Technique

Severely comminuted intra-articular fractures are highly challenging to manage due to the small size and location of the articular fragments, which often preclude the use of conventional fixation methods. These complex injuries require fixation techniques that restore joint congruity while simultaneously preserving vascularity.

We describe the Multiple Cantilever K-Wiring Technique, a novel fixation strategy. The method utilizes multiple parallel or crossing K-wires placed subchondrally in a raft-like configuration to buttress fragments and re-establish joint surface alignment. This approach allows for fragment-specific stabilization without requiring extensive dissection or placement of bulky hardware.

In our prospective series, this minimally invasive, cost-effective, and highly adaptable technique demonstrated excellent outcomes regarding joint mobility, pain control, and function in anatomically constrained fractures.
