This is a two steps observational study
In the first part we will compare the accuracy of the commercial guide against a in-hospital designed patient specific guide. As a secondary goal, the problems detected during the design phase will be described.
Once the accuracy of the guide is acceptable, we will implant the glenosphere of future patients using the PSG guide following the same engineering design process.
Reverse shoulder arthroplasty is a treatment for both non-synthesizable fractures and arthropathy degenerative. This implant is based on two main components: glenosphere and stem. The stem in turn is integrated in its upper part by a polyethylene that reduces the friction torque between the glenosphere and the stem.
Correct positioning of the glenosphere is critical for functionality and survival of the implant. Malpositioning of glenosphere can be related to:
In recent years, given the
Preoperative planning even without PSG improves the positioning accuracy of the guide in the glenoid. In glenoids with only a slight deformity, PSGs improve the accuracy of the guide entry point (<1 mm error, compared to > 4 mm under visual control) and orientation (< 3â—¦ error compared to > 7â—¦). In glenoids with more significant deformities, planning also showed superiority.
