PKP Assisted With MR Technology in OVCF With IVC

Percutaneous Kyphoplasty Assisted With/Without Mixed Reality Technology in Treatment of OVCF With IVC: a Prospective Study

To prospectively assess the outcome of PKP assisted with and without MR technology in treatment of OVCF with IVC.

The study is to prospectively assess the outcome of PKP assisted with and without MR technology in treatment of OVCF with IVC. Forty cases of OVCF with IVC undergoing PKP were randomized into a MR technology assisted group (group A) and a traditional C-arm fluoroscopy group (group B). Both groups were performed PKP and evaluated by VAS scores, ODI scores, radiological evidence of vertebral body height and kyphotic angle(KA) at pre-operation and post-operation. The volume of injected cement and Operation time was recorded. And whether cement touching both endplates or not(non-PMMA-endplates-contact, NPEC) in radiological evidence were also recorded postoperatively. The clinical outcomes and complications were evaluated afterwards. All patients received 10 to 14 months' follow-up, with an average of 12 months.

Inclusion Criteria:

• Single level OVCF in the thoracic and lumbar levels (T10-L4), suffering with severe back pain.;
• OVCF without damaged vertebral posterior wall and nerve lesion;
• The patient was over 50 years old and , the diagnosis of osteopenia or osteoporosis was confirmed by bone densitometry ;
• All patients underwent（received） plain radiography, computed tomography (CT) and MRI before surgery, and with IVC presented in MRI.

Exclusion Criteria:
