  Purpose

This study aims to compare two treatments in subacute (more than 6 week duration) non-traumatic (usually osteoporotic) vertebral fractures. The two treatments are the following:

  1. 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.
  2. 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 to fix fracture reduction. The study will indicate if balloon kyphoplasty is able to restore vertebral height of the fractured vertebra better than vertebroplasty.

Primary Outcome Measures:
  • Modification of the kyphotic angle of every treated vertebra (between the preoperative angle and measured after 1 year follow-up) [ Time Frame: 1 year ]

Secondary Outcome Measures:
  • Evaluation of pain through the visual analog scale [ Time Frame: J-20 to J-7 - J6 - J45 - J90 - J180 - J360 ]
  • Functional scale (EIFEL) for lumbar pain [ Time Frame: J-20 to J-7 - J6 - J45 - J90 - J180 - J360 ]
  • Evaluation of quality of life (QUALEFFO - Short Form SF12) [ Time Frame: J-20 to J-7 - J6 - J45 - J90 - J180 - J360 ]
  • Analgesics intake according to the WHO classification (Classes 1, 2 and 3). [ Time Frame: J-20 to J-7 - J6 - J45 - J90 - J180 - J360 ]
  • Evaluation of kyphotic angle and global thoracic and lumbar angulations [ Time Frame: At each follow-up visit (J-20 to J-7 - J6 - J45 - J90 - J180 - J360) : ]
  • Measurement of anterior, median and posterior height of the discs adjacent to the fracture; [ Time Frame: J-20 to J-7 - J6 - J45 - J90 - J180 - J360 ]
  • Measurement of disc angles adjacent to the fracture; [ Time Frame: J-20 to J-7 - J6 - J45 - J90 - J180 - J360 ]
  • Number of new vertebral fractures documented radiologically [ Time Frame: J-20 to J-7 - J6 - J45 - J90 - J180 - J360 ]
  • Medico-economic follow-up on 10% of the randomly selected patients:o Cost of intervention.o Cost of prescribed medicines.o Cost of follow-up visits.o Cost of subsequent hospitalization.o Cost of complications. [ Time Frame: J-20 to J-7 - J6 - J45 - J90 - J180 - J360 ]
  • Follow-up of anterior, median and posterior height of the treated vertebral body, obtained by making an average of all measurements, on 3 cuts CT-SCAN on the sagittal level : lateral right, median and lateral left [ Time Frame: preoperative, at J6 and at J360 ]
  • Intensity of signal with T2 sequence [ Time Frame: preoperative and at J360 ]

Arms Assigned Interventions
Experimental: 2
balloon kyphoplasty
Device: balloon kyphoplasty
Balloon Kyphoplasty, a variant of Vertebroplasty, in which a balloon is first placed into the fractured vertebra and inflated with fluid in order to create a cavity. Then, the balloon are deflated and removed. This may restore part of the vertebral height loss due to the fracture and facilitate the injection of the cement with low pressure.
Active Comparator: 1
vertebroplasty
Procedure: vertebroplasty
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
