Summary

Background The standard care in patients with a painful osteoporotic vertebral compression fracture (VCF) is conservative therapy. Percutaneous vertebroplasty (PV), a minimally invasive technique, is a relatively new treatment option. Recent randomized controlled trials (RCT) provide conflicting results: two sham-controlled studies showed no benefit of PV while an unmasked but controlled RCT (VERTOS II) found effective pain relief at acceptable costs in patients with acute VCFs. A still ongoing masked RCT (VERTOS IV) focuses on acute VCFs defined as ≤ 6 weeks. VERTOS III focused on conservative treatment and found that half of patients still had disabling pain after 3 months or longer. These patients with sustained pain after 3 months may benefit from PV. Objective To compare pain relief after PV with a sham intervention in selected patients with a chronic osteoporotic VCF ( three months or longer) using the same strict inclusion criteria as in VERTOS II an IV. Secondary outcome measures are back pain related disability and quality of life. Methods The VERTOS V study is a prospective RCT with pain relief as primary endpoint. Inclusion criteria are a VCF of thoracic level 5 or lower with focal tenderness at fracture level, assessed by an internist on physical examination and a Visual Analogue Scale (VAS) score ≥ 5 for three months or longer, decreased bone density defined as T score ≤ -1 and age 50 years or older. 94 patients will be included, 47 in each arm. Crossovers are not allowed. Follow-up is at regular intervals during one year period with VAS score for pain as primary endpoint. Secondary endpoints are back pain related disability and quality of life measured with the Quality of Life Questionnaire of the European Foundation for Osteoporosis and physical function measured with the Roland Morris Disability questionnaire. Conclusion Vertos V is a methodologically sound masked randomised sham controlled trial of vertebroplasty in patients with sustained pain 3 months or longer after a vertebral compression fracture.

Conditions

• Osteoporosis
• Vertebral Fracture

Interventions

Type	Name	Description
DEVICE	percutaneous vertebroplasty	Using fluoroscopic guidance, the practitioner infiltrates the skin and subcutaneous tissues overlying the pedicle of the target vertebra or vertebrae with 1% lidocaine and infiltrates the periosteum of the pedicles with 0.25% bupivacaine (marcaine. For the vertebroplasty procedure, 11-gauge or 13-gauge needles are passed into the central aspect of the target vertebra or vertebrae. Bone cement is prepared on the bench and injected under constant fluoroscopy into the vertebral body. Injection is stopped when the PMMA reaches the posterior aspect of the vertebral body or leaks into an extraosseous space, such as the intervertebral disk or an epidural or paravertebral vein.
PROCEDURE	Sham procedure	Using fluoroscopic guidance, the practitioner infiltrates the skin and subcutaneous tissues overlying the pedicle of the target vertebra or vertebrae with 1% lidocaine and infiltrates the periosteum of the pedicles with 0.25% bupivacaine (marcaine). During the sham intervention, verbal and physical cues, such as pressure on the patient's back, are given, and the methacrylate monomer (PMMA) is opened to simulate the odor associated with mixing of cement, but the needle is not placed and cement is not injected.
