1

Balloon Kyphoplasty which consists of placing through a percutaneous posterior approach under radiological guidance, into the fractured vertebra a balloon which is inflated with fluid and creates a cavity. This may restore part of the vertebral height loss due to the fracture. In addition, after balloon deflation, polymethylmetacrylate cement is injected with low pressure into the created cavity.

2

Vertebroplasty consisting in the percutaneous injection into the fractured vertebra of polymethylmetacrylate cement (the cement used to fix prosthesis in joint replacement) through a posterior route through the vertebral pedicles under radiological guidance

Eligibility Criteria

Age50 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patient is able to undergo the vertebroplasty or Balloon kyphoplasty procedure
  • Patient must have signed the consent form (ZELEN Randomization protocol)
  • Male or female, 50 years or older
  • One or two non-traumatic vertebral fracture(s):
  • Of osteoporotic origin (low speed trauma such as fall from his own height or less than 80 cm)
  • Fracture(s) of less than 6 weeks duration after the onset of pain related to the fracture The fracture(s) exhibit(s) high signal intensity on T2-weighted images and a benign appearance at MRI
  • The patient will be able to receive the selected protocol treatment within 6 weeks after onset of fracture-related symptoms and within 15 days after treatment randomization.
  • The benign nature of the vertebral fracture has to be confirmed by the results of the biopsy performed during vertebroplasty or balloon kyphoplasty or by one year follow-up in the conservative treatment group.

You may not qualify if:

  • Patient with a vertebral fracture of more than 6 week duration after onset of fracture-related symptoms.
  • Neurological signs related to the vertebral fracture to treat
  • History of surgical or percutaneous spine treatment except simple discectomy at a single or multiple vertebral levels with no residual pain.
  • More than two recent vertebral fractures
  • Current infection
  • Impossibility to perform the percutaneous approach of the vertebra to treat.
  • Reduction by more than 50% of the anteroposterior width of the bony spinal canal due to the vertebral fracture to treat.
  • Known allergy to a contrast media or to one of the cement components used for kyphoplasty.
  • Vertebral fracture with loss of 90%or more of the vertebral body height
  • Neurological signs or symptoms related to the vertebral fracture
  • Malignant and traumatic vertebral fractures
  • Contraindication to MRI :
  • Metallic implant : pace-maker, non movable auditive implant, metallic vascular or cardiac device
  • Metallic surgical clips
  • Claustrophobia
  • +6 more criteria
