Stryker Launches ReUnion S Humeral Stem

Share:

Stryker's ReUnion® S humeral stem is designed to be the ideal length to complement the ReUnion Shoulder Arthroplasty System. Based on study findings from the Stryker Orthopaedics Modeling and Analytics database and software, ReUnion S can address elelements of bone preservation, alignment and stability. 

"Certain humeral short stems implanted to date have been associated with unacceptable high rates of malalignment, loosening, stress shielding and other modalities of adverse bone reactions," said Joaquin Sanchez-Sotelo, MD, PhD., a surgeon at the Mayo Clinic. "This is driven by excessive shortening, increased proximal bulk, and poor implant alignment."

ReUnion S appears to preserve more bone mass proximally and distally vs. competitive stems. Soft-tissue management is the choice of the user and is not limited by the stem design. The S stem is designed to retain alignment and stability benefits of a longer humeral stem prosthesis.
