Manufacturer Narrative

Batch review performed on 21-oct-2022.Lot 2009918: (b)(4).Expiration date: 2026-01-27.No anomalies found related to the problem.(b)(4).Clinical evaluation performed by medical affairs department: revision performed at about 9 months after the primary surgery due to tuberosities re-absorption, which caused pain and limited rom.According to report, during the revision, mobilization of the stem was detected.Additionally, it seems from the radiographic images that the anatomical implant is smaller than the canal bone.We cannot tell if this is the result of post-surgery healing process of the bone, which may result in bone dimensional changes, or the surgeon's choice: in the latter case, no explanation for this decision was supplied.Therefore the new implant was chosen 2 sizes bigger.The anatomical implant was revised into a reverse implant with a lateralized glenosphere.Preliminary investigation performed by r&d: case of tuberosities reabsorption in a patient with previous proximal humeral fracture.Despite the implant mobilization noticed during the revision surgery, the humeral diaphysis shows signs of osseointegration on the coated region.No further comments can be made based on the information at hand.Additional components involved: anatomical shoulder system 04.01.0131 hc pegged glenoid ø46 (k170910) lot 1908966: (b)(4).Expiration date: 2025-02-01.No anomalies found related to the problem.(b)(4).Anatomical shoulder system 04.01.0092 metal humeral head ø44 (k170910) lot 2001148: (b)(4).Expiration date: 2025-06-29.No anomalies found related to the problem.(b)(4).Anatomical shoulder system 04.01.0023 humeral anatomical metaphysis - cementless - 135° - 6 (k170910) lot 1811225: (b)(4).Expiration date: 2024-04-06.No anomalies found related to the problem.(b)(4).
