TrueLok
Ring Fixation System
TrueLok™ Ring Fixation System
Simple. Stable. Versatile.
The TrueLok Ring Fixation System, developed at Texas Scottish Rite Hospital for Children (TSRHC) in Dallas, Texas, is a modern evolution of the original Ilizarov fixation concept. Preserving the core principles of circular fixation while incorporating contemporary design enhancements, TrueLok provides a versatile platform for fracture fixation, deformity correction, limb lengthening, limb preservation and bone transport procedures.

Simple.
Pre-assembled hinges, angular distractors and functional components are designed for straightforward assembly, alignment and adjustment.
Stable.
Specialized fixation bolts and serrated connection elements help maintain construct integrity throughout treatment.
Versatile.
Modular components support highly customized frame configurations across multiple clinical applications.
Key Features
Modular System
A comprehensive system of rings, arches, plates, fixation elements and functional modules enables surgeons to create customized constructs while reducing overall inventory complexity. Universal components help reduce the number of parts required during surgery.
Clinically Versatile
The modular nature of the TrueLok platform supports treatment of a broad range of orthopedic conditions including trauma, deformity correction, limb lengthening, limb preservation and bone transport.
Stable Fixation
Wire and half-pin fixation bolts featuring serrations and grooves are designed to provide strong bone segment stabilization and secure construct assembly. Serrated connection elements help prevent unwanted rotation and component loosening during treatment.
Proven Circular Fixation
Built upon established circular fixation principles, TrueLok preserves key Ilizarov concepts while incorporating design improvements that support contemporary limb reconstruction techniques.
Broad Compatibility
Compatible with a wide range of TrueLok family components, modules and advanced reconstruction solutions, including TL-HEX applications when multiplanar correction is required.
Foundation for TL-HEX
TrueLok serves as the fixation platform for the TL-HEX TrueLok Hexapod System, providing surgeons with a seamless pathway from conventional circular fixation to advanced deformity correction.
System Components
Built Around a Modular Circular Platform
The TrueLok platform includes rings, arches, fixation bolts, plates, rods, hinges, distractors and specialized accessories designed to support customized circular fixation constructs.
Modular components can be combined to address a wide variety of anatomical and procedural requirements while maintaining construct stability and surgical flexibility.
Clinical Applications
Fracture Fixation
Stable circular fixation for acute fractures and complex trauma cases.
Nonunion and Pseudoarthrosis
Management of challenging nonunions and pseudarthroses requiring stable fixation and progressive reconstruction.
Limb Lengthening
Supports distraction osteogenesis procedures for correction of limb length discrepancies.
Limb Preservation
Limb salvage and reconstruction procedures involving complex bone and soft tissue conditions.
Deformity Correction
Gradual or staged correction of angular, rotational and translational deformities.
Bone Transport
Frame configurations designed to facilitate segment transport and reconstruction.
