Summary
Stemless shoulder arthroplasty offers bone-sparing benefits, minimizing complications and revision risks. This review covers emerging designs and their clinical outcomes for shoulder replacement surgery.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Stemless shoulder arthroplasty, introduced in 2004, utilizes metaphyseal fixation for bone preservation.
- Current FDA-cleared options in the USA are limited, though numerous designs exist internationally.
- The technology aims to reduce humeral bone removal, fracture risks, and revision surgery morbidity.
Purpose of the Study:
- To review available stemless shoulder arthroplasty designs.
- To analyze reported clinical results and outcomes.
- To identify and discuss potential concerns regarding this evolving technology.
Main Methods:
- Literature review of stemless shoulder arthroplasty implants.
- Analysis of published data on surgical outcomes and complications.
- Examination of second-generation convertible implant features.
Main Results:
- Multiple stemless designs are available globally, with limited FDA approval in the USA.
- Metaphyseal fixation is a key feature, aiming for bone conservation.
- Second-generation convertible implants offer versatility for anatomic or reverse configurations.
Conclusions:
- Stemless shoulder arthroplasty represents an emerging trend in shoulder replacement.
- Further research and long-term data are needed to fully understand its potential and limitations.
- The technology shows promise for improving patient outcomes and reducing revision rates.
