Summary
Stemless reverse total shoulder arthroplasty (rTSA) components showed bone ingrowth, indicating osseointegration. Further studies are needed to confirm the long-term durability of this investigational shoulder implant system.
Area of Science:
- Orthopaedic Surgery
- Biomaterials Science
- Biomedical Engineering
Background:
- Stemless shoulder arthroplasty avoids humeral canal reaming.
- Extending stemless designs to reverse total shoulder arthroplasty (rTSA) presents biomechanical challenges like component subsidence and loosening.
- Stemless rTSA is investigational in the US, with ongoing clinical trials.
