Balloon Kyphoplasty Clinical Trial
Official title:
Prospective Cohort Study on the Feasibility and Reliability of 'Open' Balloon Kyphoplasty in Types A3.2, A3.3, B1 and C1 MAGERL Classification Vertebral Fractures(STIC 4)
Some unstable traumatic vertebral fractures (types A3.2, A3.3, B1 et C1 according to MAGERL
classification) may undergo unpredictable secondary displacement. Such fractures require a
two session surgery with a first operation carried out immediately to achieve posterior
fixation and a second surgery which is performed some days later to stabilize the anterior
spine and restore stress resistance.
Goal of the present study is to show that percutaneous Balloon Kyphoplasty is able to
restore anterior spine strength and replace second session surgery.
Patients with traumatic vertebral fractures type A3.2, A3.3, B1 and C1 of the MAGERL
classification will be enrolled in this open study. They will be operated on in emergency to
perform spinal canal decompression, fracture reduction and posterior fixation using fixation
plates with pedicular screws combined with bone graft.
During the same surgery or some days later on, percutaneous Balloon kyphoplasty of the
fractured vertebral body (ies) using polymethylmetacrylate cement injection through a
posterior transpedicular approach will be carried out in replacement of anterior spine
surgery to restore vertebral body strength.Patients will be followed up for one year.
Expected advantages of this management compared the conventional two session surgery include
the following:
- decreased morbidity due to suppression of the anterior surgery
- improve final spine alignment and vertebral Kyphotic angle avoiding the loss in
kyphotic angle which often occurs between the posterior and anterior surgery with the
conventional two session surgery.
