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 systematically reviewed the literature for studies of currently available canal-sparing respectively stemless shoulder arthroplasty systems.
