研究概览
简要总结
The objective of the clinical trial is to evaluate the SPACE 360 Delivery System using SPACE CpsXL Bone Cement compared to standard vertebroplasty in the treatment of pathological fractures of the spine caused by metastatic tumors of the spine, myeloma, or lymphoma. Up to a total of three levels per patient may be included or five levels for multiple myeloma. The control group will be standard vertebroplasty.
详细描述
The primary endpoint is cement leakage as determined radiographically (CT). will be cement leakage measured by CT. Secondary endpoints are reduction of pain (VAS) and quality of life measurements (Oswestry disability index).

- •Spinal metastasis (except renal cell), myeloma, or lymphoma of the spine
- •Pathological fracture(s), T5-L5, with bone marrow edema imaged by magnetic resonance imaging (MRI)
- •Visual Analog Scale (VAS) for pain of > 4 on a scale of 0 to 10
- •Oswestry score of at least a moderate disability (21-40%)
- •No major surgery to the spine planned for at least 1 month following enrollment - Defined as a procedure the magnitude of a laminectomy or more
- •Life expectancy of > 6 months.
- •Patient has sufficient mental capacity to comply with the protocol requirements
- •Availability for all study visits and phone calls
- •Understands the potential risks and benefits of participating in the study and is willing to provide written informed consent
- •Pathological vertebral fracture with 20-70% compression (compared to adjacent normal vertebral body)
- •Fracture age < 6 months
- •Signal on MRI consistent with non-healed fracture
- •Female subjects must either be no longer capable of reproduction or taking acceptable measures to prevent pregnancy during the study
- •Subject must be willing and able to comply with specified follow-up evaluations
排除标准
- •Primary tumors other than plasmacytoma
- •Renal cell tumors
- •More than 80% compression of the vertebrae
