Like with all techniques, the learning curve and routine dictate the outcomes. There are not many studies published in english, a few by Mariano de Prado (in spanish), so technically no evidence like Dr Maffulli said. I have a good deal of experience with it and my results are as good as the traditional techniques. The biggest draw back of this MIS osteotomy is the absence of internal fixation, the correction is dependent on the appropriate post-operative dressing and a tight initial follow up.
I agree with the colleagues Dr. Mafulli and Dr. Villacreses. The best technique is the one with which you have enough experience and this experience is favourable. If you have problems with your technique and the outcome is not satisfactiory, then you have to go over to a new one. This new technique would be good if it removes the unsatisfactory moments and elements of the used technique used so far.
