Event or Problem Description
The reverse shoulder prosthesis was implanted in our hospital four years ago.Its function is excellent.A firm, elastic bulge has formed anteriorly in the area of the deltoideopectoral approach.Radiological examination on (b)(6) 2024, revealed a dislocation of the glenosphere relative to the metaglene.There is an indication for replacement of the glenosphere and, if necessary, also the metaglene in conjunction with an inlay replacement.The revision surgery took place on (b)(6) 2025.The procedure was completed with no issues noted.
Additional Manufacturer Narrative
Product complaint # = >(b)(4).Investigation summary = > hcp is reporting to nca/bfarm: "the reverse shoulder prosthesis was implanted in our hospital four years ago.Its function is excellent.A firm, elastic bulge has formed anteriorly in the area of the deltoideopectoral approach.Radiological examination on (b)(6) 2024, revealed a dislocation of the glenosphere relative to the metaglene.There is an indication for replacement of the glenosphere and, if necessary, also the metaglene in conjunction with an inlay replacement.The planned surgery took place on (b)(6) 2025.The following findings were observed: (copy from the surgical report) ".This clears the path into the joint, and the articular membrane with severe metallosis is removed, both around the shaft and in the area of the glenosphere.This membrane has completely detached from the metaglene, but still articulates well with the shaft portion of the prosthesis.First, the glenosphere is removed, followed by the inlay.This provides even better access to the joint and allows the synovialectomy to continue.Only at the lower edge of the glenoid is one careful to avoid damaging the axillary nerve.Then, the screw residue of the glenosphere locking screw is exposed in the middle of the metaglene.Fortunately, it had a central hole that a conical male left-hand thread cutter engages.The metaglene is then cleanly freed of scar tissue all around, and a new 38 mm glenosphere is applied caudally with the eccentric tool.Fixed."intraoperatively, photo documentation done." the product was not returned to j&j medtech orthopaedics, however a photo was provided for review.See attachment (b)(4) photo explant.The photograph attached was reviewed, however it does not represent the reported product complaint.However, although the metaglene was not returned for evaluation and photograph provided is not representative of the reported product complaint, due to the condition observed on the dxtend glenosphere ecc d38mm, it is reasonable to conclude that a disassociation event occurred between the glenosphere and the metaglene.A manufacturing record evaluation was performed for the finished device [130760000 / 5358182], and no non-conformances or manufacturing irregularities were identified.With the information provided is not possible to determine a potential cause at this moment.The mode of failure of the device is multi-factorial and consideration must be given to all other potential influences such as surgical process, patient variables (e.G.Activity level and use), anatomical considerations and patient changes over time.Any conclusions from the investigational input provided have to be placed into context with all other relevant factors.It is highly recommended to the patient to consult with their healthcare professional for further assessment.As the device was not returned, an as-received condition could not be assessed, and a dimensional inspection and document/specification review were not completed.The overall complaint was confirmed based on the visual examination of the involved implant.Dxtend metaglene would contribute to the complained device issue.Based on the investigation findings, it has been determined that no corrective and/or preventative action is proposed.There is no indication that a design or manufacturing issue has caused the reported complaint condition.As part of j&j medtech orthopaedics quality process, all devices are manufactured, inspected, and released to approved specifications.Additional monitoring for any potential safety signals will be conducted through complaint trending and other post-market safety surveillance activities.Device history lot = > 1) quantity manufactured: (b)(4).2) date of manufacture: 1/17/2020 3) any anomalies or deviations identified in dhr: none 4) expiry date: 12/31/2024 5) ifu reference: ifu-w90930 rev.B.Device history review = > a manufacturing record evaluation was performed for the finished device [130760000 / 5358182], and no non-conformances or manufacturing irregularities were identified.H11 additional narrative: added: d10 (concomitant).
