We report a small cohort of patients with severe osteoporotic fractures treated with vertebroplasty. We note a high prevalence of small, central, intraosseous clefts in these severe fractures. Rather than filling the small amount of residual bone marrow around the periphery of these severe fractures, as suggested by previous authors, we suggest central needle placement to fill these central clefts.
我们报告了一小群接受椎体成形术治疗的严重骨质疏松性骨折患者。我们注意到这些严重骨折中存在大量小的、中央性的骨内裂隙。与之前作者所建议的填充这些严重骨折周边少量残留骨髓不同,我们建议将针置于中央以填充这些中央裂隙。
