Introduction

Mix and Match is considered a viable option for minimizing morbidity in total hip arthroplasty (THA). However in reverse total shoulder arthroplasty (rTSA) this strategy remains comparatively new. This study provides an overview of currently available implant systems and the potential combinations of glenoid and humeral components.

Materials and methods

A review of commercially available shoulder arthroplasty systems was performed. Nineteen manufacturers were contacted and asked to provide detailed information on glenoid and humeral component sizes for their rTSA systems. The reported component sizes were compiled and analyzed for possible combinations.

Results

Thirteen manufacturers (68%) consented to the publication of their component size data. Two manufacturers (11%) do not produce rTSA systems, and four (21%) did not respond to repeated inquiries. A total of 21 implant systems were reported, comprising 10 distinct implant sizes. Glenosphere and humeral inlay diameters ranged from 32 mm to 48 mm, with 36 mm being the most commonly available size (16 of 21 systems, 76%).

Conclusion

Mix-and-match implantation in rTSA is likely employed more frequently than documented, yet remains poorly investigated. This study demonstrates that numerous systems can theoretically be combined during revision surgery, although the biomechanical implications are not yet understood. Early clinical reports appear promising. The potential advantages for patients undergoing this procedure include reduced operative time, less invasive surgery with lower risk of perioperative complications.
