Differential threads provide distraction, indirect decompression

Implant design resists shear force

Immediate rigid fixation

Soft tissue-sparing access to L5-S1 disc space

Ability to compress, distract and reduceIntegrated extender tabs provide a pathway for rod delivery

Staged locking cap transforms head from polyaxial to monoaxial

Washer and screw combination for solid fixationSafe, reproducible posterior fixation Threaded working cannula ensures stable access to facet

Threaded Dilator Sheath-Atraumatic Threads assist to hold the channel against the facet

Facet Screw Driver-

Positive screw retention to the

driver

Cannulated for ability to deliver wire immediately after docking

Ability to decorticate the

facet capsule

Modular design allows optimal anchor placement

Conical tip guards against subsidence

Internal distraction against static anchors

Two-level construct resists shear forces
