BACKGROUND: Despite the known demographic shift with expected doubled rate of vertebral body @entity174 by the year 2050, a standardized treatment concept for traumatic and osteoporotic incomplete burst @entity174 of the truncal spine does not exist. This study aims to determine whether minimally invasive @entity174 care for incomplete @entity3604 using intravertebral expandable @entity702 mesh cages is a suitable procedure and may provide improved safety in terms of cement-associated complications in comparison to kyphoplasty procedure. METHODS: In 2011/2012, 15 @entity1 (10 @entity1 , 5 @entity1 ; mean age 77) with 15 incomplete @entity3604 (T10 to L4) were stabilized using intravertebral expandable @entity702 mesh cages (OsseoFix  ) as part of a prospective study. X-ray, MRI and bone density measurements (DXA) were performed preinterventionally. The clinical and radiological results were evaluated preoperatively, postoperatively and after 12  months according to the visual analogue scale (VAS), the @entity717 Index (ODI), X-ray (Beck Index, Cobb angle) and CT analyses. Wilcoxon rank sum test, sign test and Fischer's exact test were used for statistical evaluation. RESULTS: A significant reduction in @entity158 intensity (VAS) from preoperative 8.0 to 1.6 after 12  months and significant improvement in activity level (ODI) from preoperative 79.0 to 30.5  % after 12  months were revealed. Radiologically, the mean kyphotic angle according to Cobb showed significant improvements from preoperative 9.1   to 8.0   after 12  months. A vertebral body subsidence was revealed in only one case (6.7  %). No changes in the position of the posterior wall were revealed. No cement leakage or perioperative complications were seen. CONCLUSION: As a safe and effective procedure, the use of intravertebral expandable @entity702 mesh cages presents a valuable alternative to usual intravertebral stabilization procedures for incomplete @entity3604 and bears the potential to reduce cement-associated complications. TRIAL REGISTRATION: German Clinical Trials Register (DKRS) DRKS00008833 .

@entity174 care using percutaneously applied XXXX mesh cages (OsseoFix  ) for unstable @entity3604 is able to reduce cement-associated complications-results after 12  months.
