Imagine the following scenario:

You arrive in a host country where you undergo the surgery, then you remain in the clinic during the latency period which lasts on average 10-14 days and when they instruct you how to turn screws and complete a few distractions for a couple of days there, you leave the clinic and return to your home country where you continue the distraction phase for about 2-3 months while taking X-rays once in a week to send to your doc in order for him to monitor your progress and adjust the distraction rate accordingly. Then, when you're almost there (0.5 cm before your target goal) you fly back to the host country where the clinic is located at and finish the process in a week or two, including the correction phase too. After that you go back to your home country with the ex-fix locked and wait for consolidation there for months. Then you either remove the ex-fix in your home country or go back to your doc's country and remove there.

What are the risks of doing this? As you know, the distraction phase can take anywhere from 90-120 days due to low lengthening rate for tibia and also due to taking some days off and dedicating them to stretching. I'm estimating that it takes at least 3-3.5 months for 6 cm distraction with ex-fix.

There are two reasons for doing this: 1. Saving on accommodation costs which can be quite expensive if one chooses to remain in a clinic for the whole duration of the lengthening phase; 2. IDK about other countries but in case of Russia they have a 90/180 visa rule which makes it impossible to complete the whole procedure there unless they extend your visa somehow.

Has anyone done this before? I'm talking about pure external method, no LON. What can go wrong during the distraction phase which can require intervention from your doc?
