Abstract

Purpose: The purpose of this study is to demonstrate the versatility and effectiveness of the minimally invasive trans-sacral approach to the lumbo-sacral spine (AxiaLIF). Introduction: This approach can be used in accessing the L5-S1 lumbar spine and in select cases may afford access to L4-S1. We have used it repeatedly, safely, and effectively for single level degenerative disc disease as well as 2-level disease in some patients with appropriate anatomy. It affords minimally side effects. Patients tend to recovery very quickly and soft tissue is preserved especially in comparison to traditional open spine surgery. Methods: We aim to demonstrate five key representative cases in which we have used technique to access the L5-S1 or L4-S1 spine levels. A retrospective data and imaging analysis has been performed. Results: Our results confirm the safe and effective use of the AxiaLIF procedure in accessing the lumbo-sacral spine. Complications are rare. The results are reproducible. Conclusions: The minimally invasive trans-sacral approach to the spine is a safe and effective technique used more and more by the spine surgeon. The advantages of minimally invasive surgery are appreciated and the outcomes are thusfar at least equivalent to traditional spine surgery.
