Shoulder Prosthesis Joins Class II Regulatory Tier
Published Date: 6/5/2026
Rule
Summary
The FDA is officially putting the shoulder joint humeral ceramic head/metallic stem prosthesis into Class II, meaning it now has special safety rules but fewer red tape hurdles. This change helps patients get safer, innovative shoulder implants faster and makes life easier for makers by lowering regulatory costs. The new classification is effective June 5, 2026, but has been in effect since December 16, 2022.
Analyzed Economic Effects
4 provisions identified: 3 benefits, 1 costs, 0 mixed.
Hemi‑shoulder implant moved to Class II
If you need a shoulder humeral (hemi‑shoulder) implant, the FDA has classified the ceramic head/metallic stem prosthesis as Class II (special controls). The final order is effective June 5, 2026 and was applicable on December 16, 2022; FDA says this classification provides a reasonable assurance of safety and is intended to enhance patient access to innovative shoulder implants by reducing regulatory burdens.
Device now subject to 510(k) pathway
Manufacturers of this shoulder hemi prosthesis must submit a premarket notification under section 510(k); FDA has not exempted this device under section 510(m) of the FD&C Act. The device’s Class II status means sponsors can use the 510(k) process rather than premarket approval (PMA).
New special controls manufacturers must meet
Manufacturers must meet the special controls codified at 21 CFR 888.3695, including clinical data on shoulder function and adverse events; non‑clinical performance testing (mechanical fatigue, fretting/corrosion, static strength, modular disassembly strength, wear analysis, and worst‑case range of motion); biocompatibility for all patient‑contacting components; sterility and pyrogenicity performance data; validation of reprocessing instructions for reusable components; shelf‑life data demonstrating sterility and package integrity; and labeling with validated reprocessing methods and a shelf life.
De Novo classification creates a predicate
Because FDA classified this device via the De Novo process, the device can serve as a predicate for future devices of that type; other sponsors can rely on this predicate to use the 510(k) process rather than submitting a De Novo request or a PMA.
