Vascularized bone grafting using the 1,2 intercompartmental supraretinacular artery for the treatment of Preiser’s disease

VBG using the 1,2 ICSRA flap results in favorable clinical/radiographic outcomes in early Preiser's disease (stages 1-2), effectively preserving function and stability. In stage 3 disease, VBG may provide symptomatic relief but does not prevent progression. This warrants careful patient selection and consideration of alternative reconstructive options.
