Total En Bloc Spondylectomy for Solitary Spinal Metastasis without Special Instruments: A Modified Technique
Keywords:
Total En Bloc Spondylectom, Solitary spinal metastasisAbstract
Primary malignant vertebral tumor and solitary spinal metastasis are indications for the total en bloc spondylectomy (TES). The major advantage of this procedure is to minimize the risk of tumor cell contamination, lower local recurrent rate, improve survival time and quality of life for these particular patients. However, with respect to the surgical technique, TES requires the special instruments that are not available in Thailand. Thus, we need to adapt the surgical techniques for the success in this procedure. We succeed the TES procedure without using the special instruments. Therefore, the objectives of this report is to illustrate our modifications of the original surgical technique to achieve the successful TES procedure using general standard surgical equipments. The steps of our approach will be discussed in the detail. However, careful selection of patients, considering of the underlying tumor type and its extension are essential for the successful outcome.
