Abstract
Background: Primary spine tumors are rare, accounting for fewer than 5% of all tumors of the spine. Unlike metastatic spine tumors, primary tumors localized to a single location offer the potential for true cure, so a minority of the primary benign lesions will require surgical treatment. Although the development of surgical techniques and instrumentation, few literatures had reported transpedicluar lateral debridement ,bone grafting ,and posterior instrumentation for primary spinal tumors. In the current study, we evaluate the efficacy of posterior instrumentation after transpedicular lateral debridement and bone grafting in patients with primary spinal tumors at a single institution.Methods: 21 patients (13 males and 8 females; average age 30 years) with primary spinal benign tumor underwent transpedicular lateral debridement, bone grafting, and instrumentation. The average follow-up period was 29.5 months (range 12–48months). The medical records and radiographic findings of the patients were reviewed.Results: all patients who had involvement of one vertebra. Before surgery, there were one patients with Frankel grade B, three with grade C, six with grade D, and eleven with grade E. During the last follow-up examination, in ten patients with neurological deficit, one patients improved one grade, seven patients improved two grades, and the neurologic status remained unchanged in two patients. Stable bone union was observed in all cases and the average time required for fusion was 6.5 months. The kyphosis Cobb angle improved from the preoperative average of 18.61 (range 0–48) to a average of 3.9(range 13 to 0) during the follow-up period. During the follow-up period, there were no grafts or instrumentation-related stabilization problems. There was no other recurrence of tumorsConclusions: transpedicluar lateral debridement ,bone grafting ,and posterior instrumentation are safe and effective methods in the surgical management of primary spine benign tumors.
