SynFix-LR System. Instruments and implants for stand-alone anterior lumbar interbody fusion (ALIF). SynFix-LR Implants The SynFix-LR implant is a stand-alone ALIF device that incorporates the benefits of an anterior fixation plate and a radiolucent interbody spacer. The design creates a zero profile construct and includes four locking screws that is designed to provide anterior fixation and stability. Stand-alone ALIF • Biomechanically equivalent to a spacer with pedicle screws.¹* • PEEK spacer is designed to provide modulus of elasticity similar to cortical bone. • Titanium plate with...

Anatomic shape • The SynFix-LR is convex to match the anatomy of the disc space. • Two footprints and two angles are offered to accommodate individual patient anatomy. Screw and plate fixation • One-step conical locking mechanism is designed to ensure screws securely lock to plate and eliminates the need for a blocking plate. • Locking screws is designed to provide stability and load transfer near the cortex of the vertebral body. • Four locking screws diverge to form a fixed-angle construct that creates a wedge of bone (highlighted in yellow) for fixation. • Self-tapping cortical threads...

Preoperative Planning 1. Preoperative planning Instruments X000045 X-ray Template for SynFix-LR, 26 × 32 mm, 8° X-ray Template for SynFix-LR, 26 × 32 mm, 12° X-ray Template for SynFix-LR, 30 × 38 mm, 8° X-ray Template for SynFix-LR, 30 × 38 mm, 12° Determine the approximate implant size by comparing the SynFix-LR X-ray template with a lateral radiograph of the patient’s adjacent intervertebral discs. Notes: • The height indicated on the template is approximately 1 mm lower than that of the actual spacer to account for pene ration of the teeth into the vertet bral endplate. • It is...

1. Patient positioning For an anterior approach to the lower lumbar levels, p osition the patient in a slight Trendelenburg position. 2. Anterior access and approach Recommended set 01.609.102 SynFrame Basic System in Vario Case The surgical approach depends on the level to be treated. Locate the correct operative disc level and incision location by taking a lateral fluoroscopic view while holding a straight metal instrument at the side of the patient. This ensures that the incision and exposure will allow direct visualization into the disc space. Expose the operative disc level through a...

3. Exposure The locking head screws of the SynFix-LR must be inserted from a direct anterior approach. Expose the intervertebral disc such that there is sufficient space on either side of the vertebral midline, equal to half the width of the SynFix-LR. This enables the insertion of the implant without interference from adjacent soft tissue structures (major vessels, peri oneum etc.). t Once the spacer has been inserted, visualization of the entire anterior fixation plate is necessary for insertion of the locking head screws. 11    DePuy Synthes  SynFix-LR System  Surgical T
