    Re: Blood vessels at risk with a Chevron Osteotomy

    0-20%! I believe the zero, 20% though?
    I have done, literally, thousands of chevron (or Austin's) with not a single AVN of the head.
    My best guestamation of why surgeons may have problems is that the apex of the osteotomy is too far distal and the angle to large.
    Anyone else out there with no real problem with this procedure?

    Re: Blood vessels at risk with a Chevron Osteotomy

    Steve,

    If the surgeon runs as high a risk of AVN as 1:5 :confused: is it not fair to to critique the skills of the surgeon, perhaps more so than the procedure ? Any capital osteotomy can produce AVN but I have only ever seen a couple of cases, from another surgeon in 15 + years. My guess is you would need to be astonishingly aggressive and strip a lot of tissue away to produce AVN, as a rule.

    The solution is quite simple, isn't it ? Know the anatomy, the principal vessels and avoid / protect.

    Re: Blood vessels at risk with a Chevron Osteotomy

    Hi Steve, I have also performed thousands of modified Austin bunionectomies over the past two decades with only one known case of AVN. I prefer slightly longer plantar arms for increased loading stability of the osteotomy but I am not convinced this is the reason for a low AVN rate since most of my colleagues also report negligible AVN outcomes with chevron osteotomies. Cheers, Andrew Kingsford.
