Lateral Single-Position Surgery

Built on the foundation of XLIF®, NuVasive® features XLIF Crestline™, Lateral ALIF™, and Lateral MAS® Fixation, enabling lateral single-position surgery from T6-S1, helping increase O.R. efficiency, and designed to improve patient outcomes.

XLIF: The Leader in Lateral Spine Surgery

In 2003, NuVasive revolutionized spine surgery with XLIF, the only lateral approach spine procedure supported by extensive clinical evidence in more than 400 peer-reviewed, XLIF-specific publications. With hundreds of thousands XLIF surgeries since its inception, the procedure continues to transform patients’ lives through reduced blood loss, less time in the O.R., and shortened hospital stays as compared to traditional posterior fusion procedures.1 The expanded lateral procedural solutions include a comprehensive portfolio to support patients from T6-S1 with lateral single-position surgery, while utilizing advanced material interbody implants to help transform spine surgery.

Lateral Procedural Solutions

Lateral ALIF

Lateral ALIF has all the characteristics of a traditional supine ALIF and is specifically designed to access L5-S1, but performed with the patient in the lateral decubitus position. A new, versatile retractor system will enable access for multiple ALIF approaches and help bridge the gap between traditional supine ALIF and the XLIF procedure. When compared to posterior approaches, Lateral ALIF has a potential for less neural injury, while providing opportunities for a larger graft footprint, higher fusion rate, and increased lordosis.


Lateral Procedural Solutions

Lateral MAS Fixation

Lateral MAS Fixation is an adapted technique utilizing the Reline® fixation system, designed to preserve and restore spinal alignment. The single-position surgical technique is designed to provide surgeon partners reproducible results and increased O.R. efficiency.  When utilized with the NuVasive leading lateral procedural solutions portfolio it offers a complete procedural solution for single-position surgery.

Advanced Materials Science™

Modulus® XLIF

Developed through Advanced Materials Science™, the market disrupting design and manufacturing process of Modulus XLIF integrates endplate porosity with an optimized body lattice structure, providing a fully porous architecture and favorable environment for bone in-growth2 while enhancing visualization compared to traditional Ti interbody implants in a variety of imaging modalities. Modulus XLIF features two zones of microporous endplates that are designed to exhibit stiffness profiles similar to cortical and cancellous bone.2


Lateral Procedural Solutions


XLIF Crestline is a supplemental solution to XLIF, enabling lateral access when a high iliac crest or anterior psoas would preclude or discourage a surgeon from using a traditional lateral trajectory at L4-L5. This surgical technique provides surgeons the ability to achieve the goals of spinal fusion surgery while maintaining the benefits of lateral surgery.
