Aim: The evaluation of early results of combined percutaneous pedicle screw fixation
and kyphoplasty for the management of thoraco-lumbar burst fracturesMaterials and
methods: Between October 2008 and September 2009, 14 patients with
thoracolumbar burst fractures underwent percutaneous short-segment pedicle screw
fixation and augmentation kyphoplasty with calcium phosphate cement. All patients
were selected according to the type of fracture (unstable type A3 fractures based on
the Magerl classification) the absence of neurological signs and an intact posterior
longitudinal ligament on the pre-operative MRI scan. Patient demographics, comorbidities
and complications were recorded. The main endpoints included Cobb
angle correction, vertebral body height restoration and the length of hospital
stay.Results: There were 6 male and 8 female patients with an average age of 40.6
years. The average follow-up was 6.1 months. The mean kyphotic angulation
improved from 22.3 degrees pre-operatively to 7.5 post-operatively. The loss of
vertebral body height improved from a mean of 40.5 % pre-operatively to 12.8 %
post-operatively. The average duration of surgery was 40 minutes with insignificant
blood loss. There were no post-operative complications. The average length of
hospital stay was 3.5 days. Conclusion: The combination of percutaneous shortsegment
pedicle screw fixation supplemented by balloon kyphoplasty for the
management of thoracolumbar burst fractures with no neurological deficit offers
correction of the normal thoracolumbar anatomy as well as augmentation of the
anterior load-bearing column, using a minimally invasive technique. The early results
are promising.
