This medwatch is submitted to send the result of the investigation of this complaint following the project manager analysis received.Date of report, event, concomitant medical products, mfr site, report source, pma/510k, if follow-up, what type, device evaluated by mfr were updated.The product was not returned to the manufacturer.The product location is unknown.Therefore, no product evaluation could be performed.The review of the device history records and traceability did not reveal any non-conformances to specifications or deviations in procedures that might have contributed to the reported event.From the information provided, the product history records, the review of the case with the product manager, the recurrence of this type of event for this product, the investigation found the cause is a user error.The project manager reported that a white mass at the instrumented segment can be observed on the provided x-ray image.This white mass in l5 represents a different density, which is characterized by a very hard bone.It is clearly stated in the surgical technique that in normal bone structure, the insertion of the half anchoring plate is a simple and effortless step.Nevertheless in order to prepare the anchoring plate trajectory, the starter awl is recommended for each roi-a surgery.The use of the starter awl is up to the surgeon based on his surgical and product knowledge, pre-operative assessment of the patient's case and pre-operative signs of bone density on the instrumented level.Yet, in the sales order of the surgery received, the roi-a sterile starter awl for anchoring plate (reference: (b)(4) was not invoiced, meaning that it was not used during the surgery.Many attempts to the sales representatives, the customer service or the materiovigilance reporter of the hospital were made to collect additional information on the reported event.Yet, no additional information was received.Based on the available information, the reported event is related to patient hard bone and absence of sterile starter awl use as recommended by the surgical technique.The investigation found no evidence to indicate a device related issue.If additional information is received that is in conflict with this analysis, this case will be reopened and the root cause of the complaint will be reevaluated.
