Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The procedure used will be standardised across all sites (currently includes four hospitals in Melbourne, Cabrini, Alfred and Royal Melbourne Hospitals and Monash Medical Centre). Participants are randomly allocated to receive either a Vertebroplasty or Placebo Procedure. All participants will receive sedation/analgesia (midazolam and fentanyl), which will be administered by the radiologist performing the procedure. Participants undergoing vertebroplasty will have the left pedicle of the fracture vertebra infiltrated by a needle, which will be gently tapped into place using a hammer. The progress of the needle will be monitored so the correct position is determined. The bone cement (poly-methyl methacrylate) will be injected under Xray guidance, with the working time for the injection being approximately 2 minutes. A unilateral approach will be used unless there is inadequate instillation of cement, in which case a bipedicular approach will be used. Extreme care is taken to ensure that no leakage of cement occurs either into a vein or outside the bone. The injection will be stopped when significant resistance is met, when the cement reaches the posterior quarter of the vertebral body or when there is escape into extraosseous structures or veins. Only patients in the active group will receive antibiotics (Keflin) against infection. Both procedures take approximately 30-60 minutes.

Treatment: Surgery
Comparator / control treatment
Placebo procedure. Participants undergoing the placebo with have the needle inserted to rest on the lamina and the tapping noise will be simulated. Cement will be mixed in the procedure room to recreate the smell.

Placebo

Eligibility
Key inclusion criteria
1 or 2 acute painful osteoporotic spinal fracture/s confirmed on X ray with pain of no more than 12 months duration. Where more than one fracture is visible, vertebroplasty will only be performed on vertebral fractures that are acute according to MRI criteria (presence of oedema or fracture line within the vertebral body).
Minimum age
Not stated
Maximum age
Not stated
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Recent history of trauma, malignant disease in spine as determined by MRI, neurological complications, osteoporotic vertebral collapse of > 90%, contraindication to MRI, fracture through or destruction of the posterior wall, retropulsed bony fragment, pressure of bone fragments on the spinal cord, discitis, osteomyelitis, sepsis, uncorrectable coagulation disorder, medical conditions that would make the patient ineligible for emergency decompressive surgery should it be necessary to treat a procedure complication and inability to give informed consent.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The method of randomisation is by a sealed opaque envelope, opened by the treating radiologist prior to performing the procedure.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Computer-generatedRandomisation is by stratified allocation. Stratification factors are sex (M,F), duration of pain (less than or equal to 6 weeks pain, greater than 6 weeks pain) and hospital site.
Masking / blinding
Blinded (masking used)
