Manufacturer Narrative

Note: this regulatory report was previously submitted on 22-feb-2018 as regulatory report # 3006340236-2017-00016 ¿ 1.Per request, it is being resubmitted as an initial report.Event date is approximated as it was reported to have occurred 6-7 weeks after the original surgery.An exact incident date was not provided.The screw failure occurred as a result of implant subsidence and failure of the vertebral body resulting in the head of the screw being pushed downwards by the implant while the threaded tip remained stationary fixated in the bone.It was unable to be determined what directly caused the screw to fracture post-operatively.It is expected that the failure was contributed to by the lack of supplemental fixation and/or patient noncompliance to the surgeon's post-operative instruction.After reviewing the patient's post-operative fluoroscopy images, dr.(b)(6) ((b)(6) chief medical officer) stated that the l4-l5 alif level is a very mobile region, especially for a patient with grade 1-2 spondylolisthesis.Thus, while supplemental fixation is not required for (b)(6) system, it should have been used to ensure stability of the region for this patient.If information is provided in the future, a supplemental report will be issued.
