Method in general is the same - a distractor for restoration of length
and axis and maintaning during nailing.
Maybe there are more convenient devices - just let me know.
Apparently the mechanics of the frame we use can be reproduced with
different equipment. We tried a large monolateral distractor on half
pins and gave up.
To me benefits are
1)thin wires instead of half pins - quick, easy, stable, symmetric
loading.
2) Multiple wires can be inserted and secured in case of articular
involvement, rigid angular deformity
3) Knee support with telescoping rods allows to keep the leg steady in
any needed knee flexion.
4)At all it is a subset of frame assisted nailing approach and
ideology because we do many nailings after deformity correction and
lengthening with ex-fix. So half-pins also can be used in case of
prolonged correction, and removed before nail insertion while wires
are maintaining reached correction.

In general yes if apply the frame without having in mind further
actions. And often distractor can be removed after one or two locking
screws have been insterted.

I presented the techinque at the last ASAMI meeting in Kyoto, Japan. I
will upload the presentation somewhere.
BHO> and the time and expense.
We have in the theatre a couple of preassembled frames for any long
bones. It takes 10-15 min. to insert and secure 2-3 wires. Of course
we don't buy the new intra-op frame for every patient. I am aware that
in the US any frame is a single-use device but maybe intra-op
equipment like large AO distractor can be used many times?
