Secure Fixation Through a Bone-Sparing Design

Zimmer Biomet continues to lead the way in bone-preserving arthroplasty solutions with the Sidus Stem-Free Shoulder System. The Sidus System has demonstrated continued success with clinical data from a two year IDE study in the US and Canada1. The studies targeted patients with good bone stock and osteoarthritis.

Clinically-proven, bone-sparing alternative for Total Shoulder Arthroplasty.1,5 In a two-year analysis of 71 patients from the Sidus IDE Study:

Excellent survivorship of


where three patients underwent revision due to integrity of the subscapularis.



of patients have over a 30 point improvement on the ASES score from preoperative.



of patients completing two year visits successfully passed the radiographic success criteria with no progressive radiolucencies of the humeral component >2 mm and no migration or subsidence of the humeral component.

Product Features

Clinical IDE study demonstrated increased mobility and reduced pain compared to preoperative state1

In a two-year analysis of 71 patients from the Sidus IDE Study:

  • Statistically significant improvement in range of motion.
  • Significant improvement in the functions of daily life.
  • 92.6% of the patients were either very satisfied or satisfied at two years post-op. 

In a two-year analysis of 48 patients from the Bigliani/Flatow Shoulder Historical Control Study5:

  • Significant improvement in range of motion when compared to preoperative state.
  • Significant improvement in functions of daily life.
  • Satisfaction data was not recorded for Bigliani/Flatow Shoulder.

Designed for anatomic flexibility and secure fixation1–3

  • Position of Anchor is independent of humeral canal, enabling optimal coverage and tensioning
  • Flexibility to mate with a variety of Zimmer Biomet Glenoids.4

  • Anchor geometry and surface finishes designed to resist rotational and lever-out forces.

  • Four open-fin press-fit anchors designed to provide rotational stability and allow for bone through-growth. 

An efficient, bone-sparing solution, should revision become necessary

  • Humeral shaft is untouched, minimal bone is removed from the humerus.

  • Anchor contains four large windows for an enhanced view of the humerus, in case of revision.

  • Anchor contains osteotome slots that minimize the impact on bone in case of revision surgery.

Procedural efficiency with easy-to-use instrumentation

  • Single-layer tray weighing less than 10 lbs.

  • Streamlined flow of the instruments to mimic the surgical technique.

  • Revision instruments included in the single tray.
