BACKGROUND: Glenoid bone defect and extreme medialization might symbolize difficult points throughout reverse shoulder arthroplasty, particularly within the setting of revision surgical procedure. Though an answer is obtainable by the Boileau’s BIO-RSA approach in major circumstances, solely autologous iliac crest bone graft and homologous graft from bone banks can be found for revision surgical procedures, with identified disadvantages and danger of graft resorption and implant failure.
MATERIALS AND METHODS: We describe on this work a brand new approach primarily based on a personalized porous tantalum machine for use in salvage conditions, aimed toward lateralization of the glenoid element of a reverse shoulder arthroplasty. Between 2014 and 2015, 5 sufferers obtained a personalized tantalum-augmented RSA at our establishment. The augments we utilized are literally available on the market for acetabular bone loss administration: these had been opportunely ready and stuck to the steel again of the glenoid element earlier than implantation.
RESULTS: Within the 5 circumstances handled, no main or minor problems have been recorded thus far. Regardless of the brief follow-up, all of the implants are nonetheless in situ. All the sufferers referred full subjective satisfaction and return to their daylife actions with out ache inside four months after surgical procedure.
CONCLUSIONS: The personalized tantalum-augmented RSA approach represents in our expertise a helpful and protected resolution in managing glenoid bone loss and medialization. Adaptability to just about each machine available in the market ought to be thought to be vital level of energy of this system.
