摘要:
Background and Objective: Recollapse of the augmented vertebrae after percutaneous vertebral augmentation treatment for osteoporotic vertebral compression fractures has obtained much attention. Although many potential risk factors have been proposed, they are still disputed. The aim of our study was to identify the characteristics of the augmented vertebrae that had undergone a recollapse according to a systematic review from the earliest available records up to August 2017 and then conduct a meta-analysis based on eligible studies to assess significant potential risk factors for recollapse of the augmented vertebrae. Methods: Fourteen studies were identified for investigating recollapse of the augmented vertebrae. Of those studies, 9 studies were eligible for meta-analysis. Results: Pooled results showed that 5 primary factors were associated with recollapse of the augmented vertebrae, including preoperative intravertebral cleft, the affected vertebrae in the thoracolumbar region, preoperative severe kyphotic deformity, solid lump cement distribution pattern, and higher vertebral height restoration. It was possibly another risk factor that the distance between PMMA and superior end plate was relatively large. Conclusions: Careful observation of patients with these risk factors and reasonable intervention could be useful to prevent deterioration of their clinical course. © 2017 Elsevier Inc.
