StaXx® XD Expandable Device
In Situ Distraction, Minimal Retraction

The StaXx® XD Expandable Device is an expandable PEEK spacer that allows for controlled
in situ distraction in 1mm increments. The low-profile, expandable design allows for a significantly smaller working channel compared to a standard monolithic implant, which may result in less bone removal and nerve retraction. The device is designed to be expanded in situ to allow surgeons to more precisely restore proper biomechanics and balance, while accurately matching the patient’s anatomy.

Simple Technique, Precise Sizing

The StaXx® XD Expandable Device is easily expanded in situ with the squeeze of the surgical gun trigger. The StaXx® XD spacer is designed to provide optimal distraction and precise implant fit, while providing controlled implant insertion. The implants are available with convex endcaps, which based on human vertebral measurements, are designed to conform to the anatomic concavity of the endplates, maximize the surface area contact, and enhance fixation.

Attributes of the StaXx® XD Expandable Device System:

  • Controlled in situ distraction in 1mm increments
  • Less invasive
  • Convex implant design conforms to patients' anatomy
  • Lordotic implants available
  • Proven strength, PEEK modulus
Potential benefits may include reduced nerve root retraction, bone resection, and soft tissue disruption.

The StaXx® XD Expandable Device bears the CE mark and is indicated for Interbody Fusion and Vertebral Body Replacement outside the U.S.
