Stemless Shoulder Arthroplasty in Treating Severe Deformity
- 313 Downloads
Shoulder arthroplasty has undergone rapid evolution with significant advancements in design, materials, indications, and technique. Stemless shoulder arthroplasty offers many potential advantages including greater versatility in matching native anatomy, bone preservation, and less difficult revision surgery. Stemless implants also provide the theoretical advantage of decreased surgical times and less blood loss. These advantages may offer particular benefits in the setting of severe deformity. The currently available short- to midterm results are promising, but more research is needed to determine long-term survivability of the implant. Stemless reverse arthroplasty is also available, and the limited reported outcomes appear similar to the stemmed reverse implants. However, there may be a higher failure rate, and the specific indications and risks for failure have not been identified.
