Brief Summary:

Percutaneous vertebroplasty is a new procedure for treating painful osteoporotic compression fractures of the spine. Five-thousand out of 12.000 patients (16.000 vertebral fractures/year in the Netherlands) present with sudden, severe back pain in the region of the fracture.Until recently, bed rest, analgesia and physical support were the only treatment options. After decades of performing PV, no large RCT with mid-term follow-up has been published.


This will be a multicenter (6 centers), prospective, randomised, intervention study. Eligible patients will be randomised for percutaneous vertebroplasty or conservative therapy.

Study population:

Age: 50 and older, vertebral fracture, level: thoracic vertebral body 5 (Th 5) or lower, osteopenia (T-score < -1 SD), back pain for no more than 6 weeks and edema in the vertebrae on MR imaging

Statistical analyses All analyses will be performed on an 'intention to treat' principle. The planned number of subjects will be 200 in total, 100 in each intervention arm.

Economic evaluation:

Cost-effectiveness will be assessed. The costs of the procedure and the medical treatment, and of visits to medical specialists, GP's and physical therapists will be compared.

Time schedule:

The total study will take 36 months

Recruitment of patients (200) has been completed. In May 2009 the 1 year follow-up will be finished.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 200 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: VERTOS II. Percutaneous Vertebroplasty Versus Conservative Therapy in Patients With Osteoporotic Vertebral Fractures
Study Start Date : February 2006
Actual Study Completion Date : June 2010

Arm Intervention/treatment
No Intervention: 2
conservative therapy (no intervention)
Active Comparator: 1
Procedure: Vertebroplasty


The treatment consists of a transpedicular injection of polymethylmethacrylate bone cement into the collapsed vertebral body (maximal 2 vertebrae in 1 treatment session) using fluoroscopic guidance. The procedure is performed under the use of local anesthetics and the patient can be discharged the same day or after 1 night of hospital stay.

Primary Outcome Measures :
  1. To compare the cost-effectivity in the two groups [ Time Frame: 1 month, 1 year ]
  2. VAS score in time [ Time Frame: 1 month, 1 year ]

Secondary Outcome Measures :
  1. To compare pain relief and the quality of life of the patients in the two groups. [ Time Frame: 1 day, 1 week, 1 month, 3 months, 6 months, 12 months and 24 months ]
