ABSTRACT
STUDY DESIGN:
A prospective clinical study.OBJECTIVE:
The purpose of this study was to evaluate prospectively a large group of patients with thoracolumbar burst fractures who were treated with a posterior/anterior combined procedure and to report on the surgical outcomes, complications and radiographic results.METHODS:
A total of 100 consecutive patients were surgically managed with posterior instrumentation, anterior decompression and anterior strut grafting. There were 71 males and 29 females; the mean age was 36 years. Patients with osteoporotic delayed vertebral body collapse were excluded. The mean follow-up period was 30 months. Surgical outcomes such as operative time, blood loss and sagittal alignment were investigated. A neurological assessment was performed by a rating system based on the American Spine Injury Association impairment scale. An interbody fusion was judged using plain X-ray and computed tomographic scans.RESULTS:
The mean operative time was 256 min and the mean operative bleeding was 985 ml. Most of the patients were ambulatory within 3 days after surgery. Of the 76 patients with neurological injury, 54 (71.1%) recovered function following surgery. The mean local kyphosis angle was 12.2° kyphotic preoperatively and 0.8° lordotic at the final observation. The mean correction angle was 15.7° and correction loss was 2.6°. No instrumentation failure was observed and the postoperative fusion rate was 99%.CONCLUSIONS:
Posterior/anterior combined surgery with posterior pedicle screws and hooks fixation, and reconstruction by simultaneous strut grafting and anterior decompression, achieved short segment fixation and can be a useful option for surgically treating thoracolumbar burst fractures.
