During shoulder replacement surgery, the ball (humeral head) and socket (glenoid) are replaced with implants, and bone must be removed to allow the implants to be put in place. Some shoulder replacement systems have a long stem that’s inserted into the shaft of the humerus after bone has been removed.
Tornier Simpliciti is a stemless shoulder replacement system, featuring a “nucleus” instead of a long stem which means less bone is removed to secure it in place compared to a long-stem system.
Stemless shoulder replacement is less invasive and preserves more bone than traditional long-stemmed shoulder replacement systems. The benefits of stemless shoulder replacement may include:
In a US-based clinical trial, Tornier Simpliciti showed significant improvement in patient’s shoulder pain and function. 2
You may be a good candidate for Tornier Simpliciti total shoulder replacement if:
Tornier Simpliciti is not for people with poor bone quality, metal allergies or infections.
