Distal humeral fractures are among the most challenging injuries to treat. Although precise repair of the articular surface is essential during surgery, accurate reconstruction of the metaphysis contributes to the overall stability of the fracture construct. The intraosseous wiring technique has been used for small-fragment fractures.

Corrective osteotomy was planned using computer-aided design (CAD) software based on computed tomography images. According to the analysis, the radial bone had an 8° apex volar deformation in the sagittal plane.

- - The study compared the biomechanical and radiographic properties of forearm fracture fixations using a two-row screw method (DSS) versus a single-row method (NDSS) using cadaveric models.
- - Fifteen cadaver forearms were fixed with polyaxial locking plates and subjected to cyclic axial loading; the DSS group showed significantly higher rigidity and lower displacement than the NDSS group throughout the test.
- - Radiographic results showed that the DSS group had less change in volar tilt under load compared to the NDSS group, indicating greater stability with the two-row fixation design.
