Key insights in total shoulder and elbow arthroplasty

Everyday activities like eating, dressing, and washing rely on well-functioning arms. For severe shoulder and elbow problems, a joint replacement (prosthesis) may be needed to relieve pain and restore arm function. This research focuses on improving the outcomes of shoulder and elbow prostheses.

Elbow Prostheses
The reasons for needing an elbow prosthesis have shifted. While rheumatoid arthritis used to be the primary cause, fractures and trauma-related conditions are now more common. Choosing the right treatment is essential. For follow-up care, a single simple question about elbow function is often sufficient, making post-surgery evaluations less burdensome for patients.
However, elbow prostheses have limited durability. After five years, 91% of prostheses still function well. Problems like loosening, infections, and wear are possible, which makes alternative treatments preferable for younger patients.

Shoulder Prostheses
The reverse shoulder prosthesis is frequently used for severe damage, such as torn tendons or arthritis. Surgeons can choose between various surgical approaches, with similar results. Less experienced surgeons are advised to specialise in one technique, while experienced surgeons can tailor the approach to individual patients.
To improve prosthesis placement, using a larger implant size is often just as effective and more cost-efficient than other methods. After ten years, 94% of shoulder prostheses still perform well, making this treatment especially suitable for older patients.

Conclusion
This research aims to make shoulder and elbow prostheses more efficient, durable, and patient-friendly, ultimately improving the quality of life for those in need of these treatments.
