Fractures of the calcaneus, especially if they are intra-articular, will cause significant STJ arthritis. The calcaneus is a 'major player' in gait and the joints around the heel bone control the forefoot in gait. Thus, any injury in this area can affect your gait pattern and lead to stresses on other joints of your foot. In your case, it appears to be affecting your ankle, which is no suprise after a significant compression and/or comminuted fracture of the calcaneus. Significant calcaneal fractures may lead to fusions such as STJ arthrodesis or triple arthrodesis to eleviate chronic pain in this area. You will likely require a special walking shoe and orthotics once the area is healed, and time will tell. You injury is still relatively 'new' since you fractured the calcaneus just a few weeks ago. Good luck on your recovery!
