If someone tore his syndesmosis, the membrane that holds the fibula and tibia together than the ankle would be very unstable since the distal fibula is the lateral ankle bone and the distal tibia is the medial malleolus of the ankle. A syndemosis tear can be repaired with screws (the traditional method) or, as you correctly pointed out, by the tightrope procedure. Presumably Jalen had a syndesmosis tear that needed stabilization. Tua, however, might have a totally different type of injury that does not require wires or screws in order to stabilize the ankle. An MRI report and an orthopedic consultant's report would contain relevant facts in order to make a prognosis as to when the player may return to playing form. The coach said he might be able to play in a couple of weeks. I saw the way his ankle rolled and that mechanism often causes a TFL tear. With an airsplint, that can be worn while wearing a shoe, one might get enough lateral ankle support to play with a TFL tear. The next game is in 21 days. I suggest a wait and see approach.
