Abstract

Modularity is a recent advance in total shoulder arthroplasty (TSA). The use of a separate head-stem combination permits intraoperative adjustment of soft tissue tension necessary for successful TSA. Modular glenoid components allow auxiliary fixation by various coatings or screws. Short-term clinical results (<5 years) indicate that the results of modular TSA are equivalent to those of monolithic TSA. Several cases of headstem disassociation have been observed. It is possible that taper corrosion and polyethylene insert failure could occur in the long term, as has been seen with modular hip replacement.
