What tx would you use for this ankle fracture?

1?

What are the goals of tx 2?

 

1. Short-leg non-weight bearing cast for 4-6 weeks

2. 

  • Creating a relatively normal foot shape to allow use of normal footwear
  • Ensuring correct alignment
  • Establishing articular congruity to promote pain-free function
  • Prevent long-term degenerative change.
