The primary objective of this study is to evaluate the safety and effectiveness of balloon kyphoplasty treatment for painful, verbebral body compression fractures (VCFs) as compared to standard non-surgical therapy in patients with cancer.
The primary endpoint of the study is the improvement in functional status, as measured by the Roland-Morris Disability Questionnaire (RDQ) at 1 month. The primary hypothesis of the study is that the mean improvement will be larger in subjects initially assigned to management with balloon kyphoplasty.
The following secondary endpoints will also be examined. Comparisons will be made follow-up visits.
Safety:1. Rate of study treatment-related adverse events,
2. Change in neurological status.
Clinical:1. Change in functional status as assessed with the Roland-Morris Disability Questionnaire and Karnofsky Performance Scale,
2. Change in quality of life as assessed by the SF-36v2™ Health Survey,
3. Change in back pain, as measured by a 10-point Numerical Rating Scale (NRS),
4. Change in back-pain analgesics used,
5. Change in ambulation status,
6. Changes in activities of daily living,
7. Time to treatment failure.
Radiographic:1. Change in spinal deformity, defined as the degree of spine angulation as assessed by an independent radiologist at the core laboratory,
2. Rate of subsequent vertebral body fractures, as assessed by independent radiologists at the core lab. |
