Over the course of 2 1/2 years, the b.E.R.G.Approach was attempted in 202 patients scheduled for anterior interbody fusion at one or more levels.All but eight of them needed supplemental posterior fixation and/or fusion.Of these 202, 168 cases (83 male, 85 female) were completed successfully without conversion to an open procedure.Mean age in this group was 45 years, with a range of 23¿74 years.The date of event of (b)(6) 2014 is the date the literature article was published.Pma/510k: this report is for an unknown ao titanium interbody spacer (tis)/unknown lot.Part and lot number are unknown; udi number is unknown.Complainant part is not expected to be returned for manufacturer review/investigation.Without a lot number the device history records review could not be completed.Product was not returned.Based on the information available, it has been determined that no corrective and/or preventative action is proposed.This complaint will be accounted for and monitored via post market surveillance activities.If additional information is made available, the investigation will be updated as applicable.Device was used for treatment, not diagnosis.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.

This report is being filed after the review of the following journal article: thalgott j.S.Et al (2000) gasless endoscopic anterior lumbar interbody fusion utilizing the b.E.R.G.Approach, surgical endoscopy volume 14, pages 546¿552 (usa).This study aims to report that b.E.R.G.Approach offers significant technical advantages over the standard gas-mediated transperitoneal approach for alif.Over the course of 2 1/2 years, the b.E.R.G.Approach was attempted in 202 patients scheduled for anterior interbody fusion at one or more levels.All but eight of them needed supplemental posterior fixation and/or fusion.Of these 202, 168 cases (83 male, 85 female) were completed successfully without conversion to an open procedure.Mean age in this group was 45 years, with a range of 23¿74 years.All but eight patients were also instrumented posteriorly, 128 with translaminar fixation and 32 with transpedicular fixation, with or without posterolateral fusion.The surgical team has several options for fusion¿anatomic cage, screw-in cage, allograft, or autograft with the following devices: (89) femoral ring allograft/coralline hydroxyapatite; (37) ao titanium interbody spacer (tis)/coralline hydroxyapatite core; (21) ao syn cage/iliac crest autograft; (12) femoral ring allograft/local autograft; (6) bak/iliac crest autograft; (2) ray cage/iliac crest autograft; (1) harms (moss) cage/iliac crest autograft.The first 50 patients in this series have a minimum follow-up of 24 months and a maximum of 36 months.This report captures the following adverse events: one titanium interbody spacer (tis) migration of >5mm.This report is for an unknown ao titanium interbody spacer (tis).This is report 6 of 9 for (b)(4).Additional devices are captured on related complaint (b)(4).A copy of the literature article is being submitted with this medwatch.
