**Radiological Features Showing Placement of Devices and Gradual Failures**

**Figure A1.** Initial X-Ray images showing lateral subtalar dislocation with varus tibiotalar joint alignment.

**Figure A2.** 18 months post-op imaging with evidence of breakage of a distal 3.5 mm talonavicular screw.

**Figure A3.** 2 years post-op imaging with screw fracture more displaced and an additional fracture in the proximal 3.5 mm cortical screw in the tibia.

**Figure A4.** 3 years post-op showing new fracture of the most proximal 3.5 mm locking screw in the talus.

**Figure A5.** 5 years post-op with additional fractures in a 3.5 mm cortical screw in the tibia, a second 3.5 mm talonavicular screw, the 6.5 mm cannulated screw, and the 3.5 mm LCP plate.

**Figure A6.** 6 years post-op with an additional fracture in a 3.5 cortical screw in the tibia and the fractured plate became more widely displaced. The valgus deformity seen earlier had now progressed to nearly 30 degrees.
