Event Description

This report is being filed after the review of a clinical evaluation report (cer) from a related research activity database (ddra) for 78 patients with 26 females and 52 males (mean age, 61 ± 14 [21 - 90] years; 66.7% female) undergoing vbs procedures for traumatic, osteoporotic, or metastatic thoracolumbar compression fractures between 01/2012 and 12/2020 were included in the study.Minimum follow-up period was 6 months after surgery.Polymethylmethacrylate (pmma) cement (vertecem v+, depuy synthes, raynham, ma, usa) was injected bilaterally into the stent cavities.Complications: intraoperative complications - (material failure (n=2) therein no stent deployment could be seen.(n=2) insufficient ballooning (was defined as a bursted balloon or leaking contrast.Agent despite compliance with the maximum permitted filling volume and pressure.).Radiographic complications - vbs dislocation or cut out.(n=3) cut out.(any stent laying at any part outside of the vertebral cortical border was taken into account for a stent-cut-out).Radiographic complications - cement leakage - no vascular leakage reported -33 (none of the cement leakages had a clinically relevant consequence requiring further treatment.) (n=21) patients with cement leakage into the anterolateral, paravertebral region.-(n=11) patients with intradiscal cement leakage.-(n=1) patient with posterior cement leakage into the spinal canal.Radiographic complications (n=1) adjacent segment fracture.Clinical complications -revision surgery.(n=1) revision surgery.The patient developed potential procedure related spondylodiscitis with subsequent bone necrosis at the vbs level 5 months after index surgery.Therefore, a subtotal corporectomy with cage replacement, disc biopsy and posterior instrumentation was performed.This is for depuy synthes polymethylmethacrylate (pmma) cement (vertecem v+).This report captures the reported adjacent segment fracture and the patient who developed potential procedure related spondylodiscitis with subsequent bone necrosis at the vbs level 5 months -after index surgery.Therefore, a subtotal corporectomy with cage replacement, disc biopsy and posterior instrumentation was performed.This is report 3 of 6 for pc-(b)(4).
