Biomechanical studies suggest that fibular plate fixation alone is insufficient for SER4b fractures. Concurrent deltoid ligament repair seems necessary. This study explores how syndesmotic fixation, which is a simpler surgical approach, restores stability compared to deltoid repair or combined.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>Eight fresh frozen human cadaveric ankle specimens were tested sequentially by a robot in all 5 states: native, SER4b injury model with anatomic fibular plate fixation only, or reinforced with a syndesmotic screw and\/or deltoid ligament repair. Stability was measured in lateral translation (talar shift), valgus, and internal and external rotation during a constant 45-N axial load. The primary outcome was talar shift on fluoroscopic images.
