Shoulder Innovations, Inc. SI

SI Company Overview

Shoulder Innovations, Inc. (SI) is a privately held medical technology company focused on the design, development, and commercialization of shoulder replacement systems and related surgical technologies for orthopedic care. The company operates within the orthopedic medical device industry, specifically the shoulder arthroplasty and extremities segment, serving orthopedic surgeons, ambulatory surgery centers, and hospital systems that perform shoulder reconstruction procedures. SI’s primary products include shoulder replacement implants and enabling surgical technologies intended to improve procedural efficiency, implant positioning, and clinical reproducibility in total shoulder arthroplasty procedures.

The company is best known for its InSet™ Glenoid technology and associated shoulder arthroplasty platform, which are designed to address implant fixation, bone preservation, and surgical workflow considerations. SI has positioned itself as a specialized shoulder-focused company rather than a broad orthopedic implant manufacturer, differentiating itself through surgeon-driven product development and a concentrated portfolio strategy. Founded in the United States by orthopedic surgeon and entrepreneur Dr. Robert Tashjian along with industry executives and engineers experienced in orthopedic devices, the company evolved from a clinical and engineering effort to improve shoulder replacement outcomes and procedural simplicity.
