- Abstract: STUDY DESIGN: Retrospective and prospective case series. PURPOSE: The aim of this study was to assess the results of reconstruction of anterior column, fusion and complications related to cages. OVERVIEW OF LITERATURE: Literature shows that corpectomy has become a common surgical procedure for spinal infection, trauma, deformity, instability and metastasis. Also the use of reconstructive spinal cages is common after corpectomy. METHODS: Study was carried out in patients with dorsolumbar traumatic and Koch's spine. We assessed 25 patients (13 traumatic/12 tuberculous) who were treated with cages with/without any other instrumentation. Radiographs were obtained before and after the surgery. A preoperative magnetic resonance imaging was obtained in every patient. RESULTS: Fourteen patients underwent 1 level of corpectomy, 9 patients underwent 2 levels and 2 patients underwent 3 levels of corpectomy. Anterior reconstruction alone was performed in 8 patients; 360degrees reconstruction was performed in 17 patients and 2 of them underwent reconstruction through single posterior approach only. The mean kyphotic angulation improved from 21.2degrees preoperatively to 9.3degrees postoperatively and to 12degrees at final follow up. 8 patients with neurological deficits had improvement by at least one or more Frankel grade. No migration/displacement of cage was seen in any patients. CONCLUSIONS: The present study demonstrates that the vertebral body replacement after corpectomy by reconstructive cages provides a reconstruction of the anterior column, good correction of the mean kyphotic angle, and a correction maintained with cage without any cage related complication at long term follow up. The fusion can be achieved with reconstructive cage plus bone graft with or without posterior instrumentation.
