Also a red flag at the last update was over a year ago... this app would be extremely useful to orthopaedic residents if it actually worked and I hope AO finds the time to make it functional ### 1/5 — Bring back the Surgical Reference App *2020-02-09* Please back back the Surgical Reference App that was recently decommissioned. This app rather pales in comparison and is nowhere near as good for surgical trainees.
