Key result
Stemless humeral implants offer advantages over stemmed implants in anatomic total shoulder arthroplasty, including decreased operative time, reduced blood loss, reduced stress shielding, and preservation of bone stock.
Why the study?
With increasing surgeon use and research on stemless humeral implants in anatomic total shoulder arthroplasty, a concise review of their advantages, limitations, and future directions was needed.
Do stemless humeral implants improve outcomes compared to stemmed implants in patients undergoing anatomic total shoulder arthroplasty?
Do stemless humeral implants improve outcomes compared to stemmed implants in patients undergoing anatomic total shoulder arthroplasty?
Stemless humeral implants in total shoulder arthroplasty offer advantages such as bone preservation, reduced blood loss, and shorter operative times, representing a promising alternative to traditional stemmed implants.
May inform implant selection with adequate proximal bone quality; leaves open need for RCTs on outcome superiority versus stemmed implants.
Anatomic total shoulder arthroplasty (TSA) is frequently used in patients with glenohumeral osteoarthritis and other shoulder degenerative joint disease for pain relief and improving shoulder function. Much research is underway to find ways of improving TSA. One area of interest is the design and characteristics of the humeral components, with a particular emphasis on the length of the humeral stem. Currently, there is significant interest and discussion around stemless humeral implants. Stemless humeral implants have many advantages, including greater preservation of bone stock, reduced blood loss and operative times, and reduced stress shielding compared to stemmed humeral components in TSA. As many surgeons are now using these implants, much studies have been conducted evaluating the functional outcomes, biomechanical properties, and complications of these stemless humeral implants, often in comparison to other stemmed humeral implants. Here, we aim to provide a concise review of the advantages, limitations, and future directions for stemless humeral implants.

Murthi et al. (2022) conducted a review in Glenohumeral osteoarthritis and other shoulder degenerative joint disease. Stemless humeral implants vs. Stemmed humeral implants was evaluated. Stemless humeral implants offer advantages over stemmed implants in anatomic total shoulder arthroplasty, including decreased operative time, reduced blood loss, reduced stress shielding, and preservation of bone stock.
