Posterior lumbar interbody fusion a mid-term review of 60 cases.
It is the purpose of this study to evaluate the clinical and radiographic medium-term results of a series of 60 patients submitted to intersomatic lumbar fusion by posterior approach, using a system constituted by carbon wedges to be associated with bone grafts for intersomatic fusion, and by steel or titanium plates or bars used for posterior pedicle osteosynthesis. Satisfactory clinical results were obtained in 88.2% of cases and complete radiographic fusion in 91.4% of cases. Complications were generally observed in 8.3% of cases. In light of these results, we may consider intersomatic lumbar fusion by posterior approach a method that is perhaps aggressive, but effective in the treatment of severe lumbar spondylolysis. The use of carbon wedges brings several advantages that favor intersomatic fusion, its progressive control, and the restoration of normal lordosis of the lumbar spine.
