Clinical and radiological results 6 years after treatment of traumatic thoracolumbar burst fractures with pedicle screw instrumentation and balloon assisted endplate reduction

摘要

BACKGROUND CONTEXT: When used to fixate traumatic thoracolumbar burst fractures, pedicle screw constructs may fail in the presence of severe vertebral body comminution as the intervertebral disc can creep through the fractured endplates leading to insufficient anterior column support. Balloon-assisted endplate reduction (BAER) and subsequent calcium phosphate cement augmentation may prevent this event by restoring the disc space boundaries. The results of the first studies using BAER after pedicle screw fixation are encouraging, showing good fracture reduction, few complications, and minimal loss of correction at 2 years of follow-up.
