Low Profile Design

Streamlined footprint optimized to minimize internal construction bulk and tissue irritation.

⌖

Self-Tapping Threads

Proximal tapered starting tips support smooth initial bite without requiring tap pathways.

⚄

Anti-Splay Architecture

Reverse buttress threading and localized slots prevent housing head displacement under loads.

Titanium Biocompatibility

Extra Low Interstitial (Ti6Al4V ELI) alloy maximizes mechanical longevity and osseointegration.

Designed to Close.
Built to Care.

Kentrospine® PSS provides single and multilevel fixation modular assemblies consisting of Monoaxial, Polyaxial, Dual Core, Reduction, and Fenestrated Pedicle screws backed by specialized PSS locking caps, longitudinal rods, and cross-linking connectors.

The semi-conical screw shaft geometry combined with specific cortico-cancellous spacing creates supreme pull-out protection matrix stability. The internal star-drive mechanism effectively isolates tightening tools from accidental slippage, minimizing intraoperative disruptions.

Cortico-Cancellous Pitch

Dual-zone thread paths deliver highly efficient fixation across both dense outer bone layers and inner vertebral structures.

Star Drive Capture Slots

Deep-set inner drive channels effectively eliminate cross-threading risks during quick locking cap torquing phases.

High-Strength Stabilization Rods

Precision-drawn 5.50 mm straight longitudinal titanium bars maintain spinal posture settings through adaptive fusion steps.

Cross-Link Flexibility

Adjustable link blocks isolate rotational shifts, protecting multi-segment constructs from unwanted shifting forces.
