Study DesignWe retrospectively reviewed surgical results of posterolateral transpedicular partial corpectomy without anterior vertebral reconstruction in 23 consecutive patients with symptomatic metastatic spinal cord compression at thoracic spine.ObjectiveTo evaluate postoperative outcomes and survival rates of patients undergoing transpedicular partial corpectomy without anterior vertebral reconstruction.Summary Of Background DataThe need for anterior reconstruction after radical resection of vertebral body tumors has been emphasized by several authors. However, the stability of thoracic spine is substantially increased by the rib cage. The role of reconstruction may be not necessary in thoracic spine when partial corpectomy is performed.MethodsFrom November 2001 to November 2006, 23 patients with symptomatic metastatic spinal cord compression at thoracic spine underwent palliative surgery using a transpedicular partial corpectomy without anterior vertebral reconstruction. The indication for surgery was neurologic progression due to spinal cord compression.ResultsPatients ranged in age from 20 to 88 years (mean, 57.0 years). Neurologic improvement by at least one Frankel grade was noted in 19 of 23 cases (82.6%). Overall, 73.9% of patients (17 of 23) could walk after surgery. There was no intraoperative mortality. Median survival time was 11.3 months. There was no implant failure.ConclusionThe results of this study suggest that the stability of implants can be maintained up to 55.8 months without anterior vertebral reconstruction in thoracic spine.
