Researcher Profile & Settings

Research

Overview of research:
Conventional approach, such as piecemeal excision of spinal tumor leads to local recurrence in most patients with spinal tumors, because of residual tumor and tumor cell contamination of the surrounding structures. To reduce local recurrence as far as possible, we have developed a new surgical technique of spondylectomy (vertebrectomy), termed Total En Bloc Spondylectomy (TES). We have studied clinically and basically to improve the surgical technique and related issues in these 20 years."
