Summary
BACKGROUND: Earlier research have reported a excessive incidence of re-collapse of the augmented vertebrae after percutaneous vertebral augmentation (PVA) for osteoporotic vertebral compression fractures (OVCFs) with intravertebral vacuum cleft (IVC) throughout long-term follow-up. Earlier IVC may be thought of an necessary predisposing issue for re-collapse, however the prior research couldn’t discover a important correlation.
OBJECTIVE: To find out the incidence and distribution traits of IVCs and to additional assess IVCs of their various areas. To evaluate the long-term therapeutic efficacy of PVA for OVCFs with IVC.
STUDY DESIGN: A retrospective cohort examine.
SETTING: Division of spinal surgical procedure, an affiliated hospital of a medical college.
METHODS: A retrospective evaluate was carried out on 594 sufferers who underwent PVA to deal with OVCFs from January 2010 to December 2013. Eighty-two sufferers with the IVC signal had been enrolled within the examine. The follow-up interval was a minimal of two years. The distinction between IVC and non-IVC sufferers was in contrast. Comparisons of the radiological and medical findings at various IVC areas had been made pre-operatively and post-operatively (quick, at one yr, and at 2 years).
RESULTS: IVC incidence correlated with older affected person age and extreme demineralization. Different baseline parameters confirmed no important variations. The speed of cement leakage and vertebral fracture was considerably decrease within the IVC teams than within the non-IVC teams intraoperatively. There was no important distinction within the incidence of cement leakage or adjoining vertebral fractures between the three IVC teams. Within the quick postoperative interval, all sufferers benefited from important enchancment in vertebral physique top and kyphotic angle correction. Nonetheless, important re-collapse was noticed on the 2-year post-operative follow-up for the IVC sufferers when in comparison with the non-IVC sufferers. Among the many three IVC teams, essentially the most extreme re-collapse was noticed with inferior endplate IVCs. Superior endplate IVCs and IVCs extending to each endplates demonstrated solely delicate re-collapse on the 2-year follow-up.
LIMITATION: Because of the infrequency of this course of, the variety of sufferers with IVCs was small.
CONCLUSION: PVA therapy was initially efficient in all sufferers with OVCFs. Nonetheless, important re-collapse of the augmented vertebrae with IVCs, particularly these with inferior endplate IVCs, was discovered with long-term follow-up. Key phrases: Intravertebral vacuum cleft, percutaneous vertebral augmentation, osteoporotic vertebral compression fractures, affected vertebrae, augmented vertebrae.
