Abstract
Objective: To analyze the surgical outcome of traumatic lumbosacral spondylolisthesis treated using posterior lumbar interbody fusion, and help spine surgeons to determine the treatment strategy. Methods: We reviewed retrospectively five cases of traumatic lumbosacral spondylolisthesis treated in our hospital from May 2005 to May 2010. There were four male and one female patient, treated surgically using posterior lumbar interbody fusion. The patients’ data including age, neurological status, operation time, blood loss, follow-up periods, X- radiographs and fusion status were collected. Results: All the cases were treated using posterior lumbar interbody fusion to realize decompression, reduction and fusion. Solid arthrodesis was found at the 12-month follow-up. No shift or breakage of the instrumentation was found, and all the patients were symptom-free at the last follow-up. Conclusion: Traumatic lumbosacral spondylolisthesis can be treated using posterior lumbar interbody fusion to realize the perfect reduction, decompression, fixation and fusion.
Highlights
Traumatic lumbosacral spondylolisthesis is rare injury.[1,2,3] and mostly published as case report
Traumatic lumbosacral spondylolisthesis is the result of high-energy injury, usually accompanied with multi-trauma,[7] and the concomitant transverse process fractures were reported in most of cases.[9]
All the cases had transverse process fractures, three of five cases had limb or rib fractures concomitantly, indicating the combination of several serious forces acted in the occurrence of the rare injury
Summary
Traumatic lumbosacral spondylolisthesis is rare injury.[1,2,3] and mostly published as case report. The widespread use of MRI and CT in recent decades has facilitated the early diagnosis of the injury and more cases have been reported in English literatures,. Some cases were treated successfully using conservative methods,[7,8] most authors suggested the conservative treatment would result in posttraumatic translational instability or chronic low back pain and need late reconstruction.[1,3] In addition, the lesion belongs to a three-column injury[9] and a solid internal fixation is needed. Most authors advocate the surgical treatment for the lesion.[1,2,3,9] Treatment considerations must seek to restore normal alignment, decompress the nerves and stabilize the lumbar spine, by open reduction and rigid internal fixation.[10]
