Post made on Dr. Mahboubian's Instagram account: https://www.instagram.com/p/0ltRDyQcuK/

The description reads "Great photo showing the proportions of our patient who lengthened his femurs 8 cm ‪#‎DrMahboubian‬ ‪#‎HeightLengthening‬ ‪#‎LegLengthening‬ ‪#‎Orthopedics‬ ‪#‎LA"

Note how they say "our patient".

The original photo was posted by a member of Limb Lengthening Forum named "ShyShy". His original post can be found here: http://www.limblengtheningforum.com/index.php?topic=649.msg11099#msg11099

ShyShy went to Dr. Guichet and was not a Dr. Mahboubian patient.

In the comments, they take credit for the minimal scars and call "Dr. M a very skilled surgeon".
