Segmental and global lordosis changes with two-level axial lumbar interbody fusion and posterior instrumentation.

Background: Loss of lumbar lordosis has been reported after lumbar interbody fusion surgery and may portend poor clinical and radiographic outcome. The objective of this research was to measure changes in segmental and global lumbar lordosis in patients treated with presacral axial L4-S1 interbody fusion and posterior instrumentation and to determine if these changes influenced patient outcomes.

Methods: We performed a retrospective, multi-center review of prospectively collected data in 58 consecutive patients with disabling lumbar pain and radiculopathy unresponsive to nonsurgical treatment who underwent L4-S1 interbody fusion with the AxiaLIF two-level system (Baxano Surgical, Raleigh NC).

Clinical and radiographic outcomes with L4-S1 axial lumbar interbody fusion (AxiaLIF) and posterior instrumentation: a multicenter study.

Introduction: Previous studies have confirmed the benefits and limitations of the presacral retroperitoneal approach for L5-S1 interbody fusion. The purpose of this study was to determine the safety and effectiveness of the minimally invasive axial lumbar interbody approach (AxiaLIF) for L4-S1 fusion.

Methods: In this retrospective series, 52 patients from four clinical sites underwent L4-S1 interbody fusion with the AxiaLIF two-level system with minimum 2-year clinical and radiographic follow-up (range: 24-51 months).

Axial presacral lumbar interbody fusion and percutaneous posterior fixation for stabilization of lumbosacral isthmic spondylolisthesis.

Study Design: Case series.

Objective: To describe a minimally invasive surgical technique for treatment of lumbosacral spondylolisthesis.

Summary Of Background Data: Traditional surgical management of lumbosacral spondylolisthesis is technically challenging and associated with significant complications.

Minimally invasive axial presacral L5-S1 interbody fusion: two-year clinical and radiographic outcomes.

Study Design: Retrospective case series.

Objective: The primary aim of this study was to evaluate and report the 2-year clinical and radiographic outcomes associated with a L5-S1 interbody fusion procedure that employs an axial presacral surgical approach.

Summary Of Background Data: There are a number of lumbar interbody fusion procedures used to treat painful, degenerated discs.
