Initial reports is that Colt's Vontae Davis suffered and ankle sprain. How could this be confused with what his is confirmed with having now a foot sprain? Very easily upon a cursory review. Let's review the anatomy of the area. There is a joint below the ankle joint that is intimately connected with a very important foot joint the, subtalar joint (STJ). The illustration below shows the mechanism of injury that can be the source of either an ankle or subtalar / foot sprain.
Treatment is usually an immobilization boot, CAM BOOT, for 4-6 weeks with physical therapy. Physical therapy can consist of cold laser therapy, prolotherapy, ultrasound, estim, etc.
