Abstract: | In anatomical shoulder arthroplasty glenoid replacement is a critical point. Although total shoulder arthroplasty (TSA) provides better functional and pain results than hemi shoulder arthroplasty (HSA) there is great reluctance to implant a glenoid. For successful glenoid replacement it is necessary to preoperatively evaluate clear indications for glenoid replacement. Planning is a crucial point and has to be done thoroughly. The gold standard is an all polyethylene cemented glenoid. The implantation technique is most important to obtain an excellent and long-term result without complications. Significant key factors are preservation of the subchondral bone and an anatomical reconstruction of the glenoid. It seems that after a period of 10 years the loosening rate of glenoids increases and revisions rates rise. Therefore there is a high demand to develop new implants and a need for improved and convertible glenoids with better modularity and alternative options for fixation. |
