Stemless shoulder prosthesis versus conventional anatomic shoulder prosthesis in patients with osteoarthritis

Nine-year outcome after anatomic stemless shoulder prosthesis: clinical and radiologic results.

BACKGROUND Several stemless shoulder implants are available on the market, but only a few studies have presented results with sufficient mid- to long-term follow-up. The present study evaluated clinical and radiologic outcomes 9 years after anatomic stemless shoulder replacement. METHODS This is a prospective cohort study evaluating the stemless shoulder prosthesis since 2005. Anatomic stemle...

Shoulder Prosthesis

Measurements of shoulder prosthesis positioning

One of the most difficult aspects of shoulder arthroplasty is retroversion. The ideal angle is about 30 of posterior rotation of humeral head with regard to the frontal plane so that the humeral head squarely faces the glenoid surface in the resting position.The axis, lateral epicondylemedial epicondyle is often taken as reference and serves as landmark in many arthroplasty instrumentation. [1,...

Are there differences between stemless and conventional stemmed shoulder prostheses in the treatment of glenohumeral osteoarthritis?

BACKGROUND Conventional stemmed anatomical shoulder prostheses are widely used in the treatment of glenohumeral osteoarthritis. The stemless shoulder prosthesis, in contrast, is a new concept, and fewer outcome studies are available. Therefore, the purpose of the study was to investigate the early functional outcome and postoperative proprioception of a stemless prosthesis in comparison with a ...

Anatomic stemless shoulder arthroplasty and related outcomes: a systematic review

BACKGROUND The latest generation of shoulder arthroplasty includes canal-sparing respectively stemless designs that have been developed to allow restoration of the glenohumeral center of rotation independently from the shaft, and to avoid stem-related complications. The stemless prosthesis design has also recently been introduced for use in reverse arthroplasty systems. METHODS We systematica...
