FDA 510(k) Recap: 10 Shoulder Implants and Technologies

We have identified nearly 50 companies that market devices for shoulder joint replacement, globally, with the majority headquartered ex-U.S. To help keep an eye on shoulder technologies cleared for U.S. marketing, we highlight 2019 clearances through September, which includes two stemless options freshly added to the lineup, like Arthrex’s Eclipse Shoulder and Zimmer Biomet’s second stemless offering, Comprehensive Nano, which gained clearance in early 2Q and joins its Sidus device in bone-sparing designs.

Eclipse Shoulder Prosthesis System, K183194 (Pictured above)

  • Submitted November 2018, granted July 2019
  • Primary predicates: Arthrex Univers II, Zimmer Biomet Sidus Stem-Free, Wright Medical Simpliciti    
  • Stemless humeral joint designed as a humeral head replacement
  • Components made from Cobalt Chromium and Titanium alloy; trunnion features a titanium plasma spray Calcium Phosphate coating
  • Humeral component is fixated with a hollow screw; glenoid components are intended for cemented fixation in the joint and must only be used with appropriate bone cement
  • Compatible with pegged, keeled and VaultLock glenoids
  • Reportedly the only stemless shoulder in the U.S. that is fixated with a screw (vs. press fit)
