Firebird NXG
Spinal Fixation System

As one of the first companies to develop a modular pedicle screw system, the Firebird® NXG represents Orthofix’s four generations of modular pedicle screw system experience. The system is designed for comprehensive posterior thoracolumbar surgical cases including degenerative disc disease. The next generation Firebird platform refines the modular screws, provides a lower profile body and simplifies instrumentation thus improving upon this already versatile system.

Product Highlights


  • 2 instrument cases and 1 implant case to optimize volumes​ in sterile processing
  • Unique tubular rod reducer offers up to 28mm of reduction
  • Modular and Multi-Axial screw drivers to accommodate modular and
    pre-a​ssembled screws​

Implants Modular Bodies:

  • Slimmed implant waist by 20% allowing for improved in​ situ visualization​​
  • Reduced height above the rod by 6% creating a lower profile similar to industry leading pedicle screw systems​
  • Decreased run on rod w​ithout compromising rod security
  • Reduction body allows for 22mm of reduction​
  • Allows 50° con​e of angulation once attached to modular screw ​

​Implants Titanium Screws:​

  • Modular design for maximized visualization during screw placement
  • Non-cannulated and cannulated options support a variety of surgical approaches
  • Threads extend to the tip for controlled insertion and tactile feedback
  • Sharper tip angle, dual lead thread form to facilitate smooth screw insertion


The Firebird Spinal Fixation Systems are intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion as a pedicle screw fixation system (T1-S2/Ilium), in the treatment of the following acute and chronic instabilities or deformities:

  • Degenerative disc disease (defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies)
  • Spondylolisthesis
  • Trauma (i.e., fracture or dislocation)
  • Spinal stenosis
  • Deformities or curvatures (i.e., scoliosis, kyphosis, and/or lordosis)
  • Tumor
  • Pseudoarthrosis
  • Failed previous fusion

When used for fixation to the ilium, the offset connectors of the Firebird Spinal Fixation System must be used in conjunction with pedicle screws placed at the S1 or S2 spinal level.

The Firebird Spinal Fixation Systems components are used with certain components of the Spinal Fixation System (SFS), including rods, rod connectors and cross-connectors.

When used for posterior pedicle screw fixation in pediatric patients, the Firebird Spinal Fixation Systems are indicated as an adjunct to fusion to treat adolescent idiopathic scoliosis. Pediatric pedicle screw fixation is limited to a posterior approach.

The Firebird Spinal Fixation Systems are intended to be used with autograft or allograft.

The Phoenix® MIS Fixation System when used with the Firebird Spinal Fixation Systems is indicated to provide the surgeon with a minimally invasive approach for posterior spinal surgery.

The JANUS Midline Fixation Screw and the JANUS® Fenestrated Screw when used with the Firebird Spinal Fixation Systems is indicated to provide the surgeon with an open, minimally invasive or midline approach for posterior spinal surgery.  The JANUS Fenestrated Screws are intended to be used with saline and radiopaque dye.


  • Morbid obesity
  • Mental Illness
  • Alcoholism or drug abuse
  • Pregnancy
  • Metal sensitivity/allergies
  • Severe osteopenia
  • Patients unwilling or unable to follow post-operative care instructions
  • Use of the Firebird offset connectors for fixation to the ilium is contraindicated when the sacrum is absent or insufficient for implantation of pedicle screws at the S1 or S2 spinal level.
  • Any circumstances not listed under the heading indications.​
