Optimizing the Eden-Hybinette Procedure With 3D-Printed Patient-Specific Instrumentation: A Technical Note

The Eden-Hybinette procedure using an iliac crest bone graft is indicated in cases of recurrent anterior shoulder instability with major glenoid bone loss (>40%), coracoid dysplasia, or failure of Latarjet or Bristow-Latarjet procedures. We describe an open Eden-Hybinette technique supported by a 3D-printed patient-specific cutting guide for iliac crest graft harvesting, combined with a dedicated positioning device (HyLa, Hybrid Latarjet, Newclip Technics®). Preoperative planning based on CT scans allows precise assessment of glenoid bone loss, calculation of graft dimensions, and determination of optimal screw length and orientation. The patient-specific guide enables reproducible tricortical graft harvesting, while the HyLa device provides intraoperative control of graft positioning, avoiding graft overhang or medialization. The technique can be performed either open or arthroscopically. The use of patient-specific instrumentation allowed accurate graft sizing and placement, with postoperative imaging confirming graft congruency and fixation stability. Patients resumed physical activity within six months without recurrence of instability or donor-site morbidity. This technical note highlights the potential advantages of combining 3D-printed patient-specific guides with dedicated instrumentation for the Eden-Hybinette procedure. Anticipating graft size, shape, and screw trajectory may improve accuracy, reproducibility, and safety in revision shoulder stabilization. Further clinical studies are required to validate outcomes compared with conventional techniques.
