Optimizing total elbow arthroplasty
Optimizing total elbow arthroplasty
The elbow is a complex joint essential for daily activities such as eating, writing, and lifting. Pain or limited movement can severely reduce function and quality of life. In patients with rheumatoid arthritis, osteoarthritis, or complex fractures, a total elbow prosthesis (TEA) can be a solution.
Although TEA is rare, complications are common and prostheses have a limited lifespan. This thesis of Daniëlle Meijering investigates how outcomes can be improved by optimizing prosthesis design, patient factors, and surgical technique.
First, two commonly used prostheses were studied. Both had a 10-year survival rate of about 81–82%, but some patients showed early signs of loosening, despite high satisfaction. This highlights the importance of long-term, structured follow-up.
Second, elbow loading during daily activities was examined. Many tasks exceed the safe limits of the prosthesis, and current postoperative instructions are insufficient to reduce stress. This underscores the need for better guidelines and patient-specific advice to prevent overloading.
Third, surgical techniques were compared. A triceps-sparing approach resulted in better elbow function than a triceps-detaching technique, without increasing complications.
In conclusion, TEA can be successful despite high complication rates. Improvements in prosthesis materials, careful attention to joint loading in daily activities, and the use of optimal surgical techniques can enhance function, longevity, and safety of the prosthesis. Patient satisfaction remains high, emphasizing that TEA continues to be a valuable option for people with severe elbow problems.
