- Discussion:
- local or
Split compression frx have centrally depressed fragments;
- AVN is diagnosed when serial X-ray show a gradual shrinking
of the eleveated fragments until a defect remains;
- surgically elevated articular fragments always are avascular;
- fortunately most elevated frags regain vascularity before they begin to absorb;
- although AVN cannot be prevented, about 1 cm of cancellous bone should be
retained with elevated fragments;
