Segmental fixation of lumbar burst fractures with Cotrel-Dubousset instrumentation.

A retrospective review of 17 patients who underwent bilateral transpedicular decompression, instrumentation with a Cotrel-Dubousset construct, and posterolateral fusion with iliac crest bone graft for treatment of lumbar burst fracture is presented. All patients were followed to fusion with an average follow-up of 18.9 months. Fifteen of sixteen patients returned to preinjury occupation and/or activity. All patients reported good to excellent clinical results. The average postoperative progression of kyphosis was 11.9 degrees. There was no significant change in anterior vertebral height between the preoperative and postoperative periods. We conclude that although excellent early clinical results can be obtained using this operative strategy, the long-term effect of residual kyphosis at the fracture site is unknown.
