Investigation manufacturing records were checked confirming the batch number involved was manufactured correctly up to specification and in-line with the relevant checks and tests.No manufacturing deviations were reported.According to the labelling of smr reverse humeral body 140°, for this component the coupling is only allowed with liners belonging to the codes 1360.50.0xx, 1361.50.0xx, 1360.50.8xx, 1361.50.8xx.Therefore, the coupling with a reverse liner with product code 1365.50.821 should be considered an off-label use.Explants and x-rays analysis the explants are not available for further investigation.However, the complaint source shared the relevant x-rays, that have been sent to the medical expert for evaluation.Based on his opinion, "this is a case of surgical error induced dissociation or instability"." loosening of a liner almost always is a surgical error by not engaging the conical taper correctly.When there it is hard to prove afterwards, the aforementioned facts give some idea that a surgical error is the most likely reason for this early revision.I cannot see an implant-related problem here." therefore, considering that: - no anomalies have been found by checking the manufacturing charts of the involved component.- according to the medical expert's evaluation, a surgical error is the most likely reason for this revision and there is no evidence of implant-related concerns.We can conclude that the issue is not product related.Pms data according to the pms data, the occurrence rate of dislocation for the smr reverse liners belonging to the product family codes 1360.50.Xxx, 1361.50.Xxx and 1365.50.Xxx is around (b)(4) %.No corrective actions are required for this specific case.Limacorporate will continue monitoring the market to promptly detect any further similar issue.Note: this is a final mdr.
