Balloon Kyphoplasty Clinical Trial
— TRAUMAA3B1C1Official 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.
