I got splint for ankle fracture. Is this the best treatment for my injury?

Hi doctor,

I am a 48-year-old male. I had an X-ray of my right ankle. The technique used was three view exam. The findings are as follows: Spiral fracture of the distal fibula. This is anatomic in alignment. Cortical avulsion of the medial malleolar process. The cortex of the malleolus at the deltoid ligament attachment has been avulsed. There is a nondisplaced posterior tibial malar fracture. The talus appears to sit somewhat posterior in the ankle joint on the lateral view which could be a rotation. I believe there is an incidental fibrous cortical lesion on the lateral surface of the tibial shaft just above the ankle joint. Note that for thoroughness. A hard half splint was applied in ER and that same splint remains on after a visit with an orthopedic surgeon. I have a follow-up visit in a few days. My concern is, was this the best course of treatment for this injury? I was told that I could bear weight as tolerated but that is nearly impossible due to the amount of discomfort. This damage was caused by a fall. I have attached my X-rays here.
