I have no problem with the MIS bunions from a simplicity standpoint, but it's just a base wedge once it's healed... that's all it is.
(a base wedge that did major devascularization to the first met medullary canal).
The short term results, recover, low complications in skill hands, etc are fine... but long term may or may not be such.
We've been through timespans when pods did a lot of met osteotomies (base wedge, Austins, Scarf and other randomness).
We know how that story ends. We know met osteotomies have their issues. The indications are more narrow now.
I do tons of revision bunionectomy surgery, and most of us do... for Austin recur, proximal osteotomy recur, McBride recur, Austin OA, whatever.
The revision/salvage mostly end up needing fusions later (MPJ or Lapidus if severely undercorrected). Not fun when they're older.
The MIS bunionectomy will almost all have recurrence, and they'll need MPJ fusion.. and the MIS really destroyed the medullarry canal of the first met. The hardware is also absolutely in the way for revision/salvage. So, the revision of MIS stuff people do today is going to be fairly ugly and complicated. That is my main concern. Time will tell.
Where I'm at, and where I have been at, is that probably half my bunions are Lapidus (any reasonably young/active/flexible person),
about a third are MPJ fusion (revision/salvage, DJD first MPJ, etc)...
and that remaining 1/6 or so of bunions are other type (Austin or other met osteotomy, McBride, Valente, etc)
The MPJ fusions and other type are usually salvages of recur bunions and fail implants and etc for very old and minimally active ppl. Lapidus aren't hard once trained/exp, and they don't have a long recovery with lock plates. Lapidus do have their issues (mostly just HWR), but the met osteotomies just don't hold up well in time. We know this.
