LRS B Bone Lengthening Fixator G1320-B

Limb reconstruction demands a fixator that adapts to the patient — not the other way around. The G1320-B LRS B Bone Lengthening Fixator by Amis Orthopedic is a precision-engineered monolateral system designed to deliver controlled, gradual bone lengthening and transport across the full range of clinical presentations — from pediatric congenital limb discrepancies to adult post-traumatic bone defect reconstruction.

The Versatile Standard for Limb Lengthening

The G1320-B is built on the proven monolateral LRS platform, combining a modular low-profile frame with a reliable screw-driven distraction mechanism. Its 4-pin bone anchoring configuration provides secure fixation for the majority of limb lengthening indications — offering an excellent balance of rigidity, patient comfort, and clinical adaptability.

Whether the indication is a tibial lengthening in an adolescent, a post-traumatic humerus bone transport in an adult, or correction of a congenital leg length difference, the G1320-B adapts to different bone diameters, patient sizes, and lengthening requirements through its modular clamp and bar length system.

Gradual, Controlled Distraction Osteogenesis

The clinical effectiveness of any bone lengthening fixator rests on the quality of its distraction mechanism. The G1320-B features a linear screw-driven distraction unit that has been refined for smooth, consistent force delivery throughout the lengthening process:

• Incremental lengthening at 1mm/day (surgeon-adjustable) — following the Ilizarov biological principle of tension-stress
• Scale-marked distraction rod — allows accurate tracking of cumulative lengthening without measurement errors
• Smooth, uniform distraction force — supports consistent bone regenerate formation in the callotasis zone
• External patient adjustment — patients or caregivers perform daily adjustments at home, reducing clinic visit frequency

This mechanism is appropriate for both the lengthening phase (active callus formation) and the consolidation phase (bone mineralization and maturation), without requiring hardware modification between phases.

Low-Profile Frame for Patient-Centered Care

Limb reconstruction treatment timelines often span months. Patient comfort, quality of life, and compliance directly affect treatment success. The G1320-B’s monolateral (single-sided) design was chosen with these realities in mind:

• Minimal hardware profile — no circumferential frame, reducing bulk and allowing patients to dress and bathe with less difficulty
• Radiolucent-compatible construction — does not obstruct X-ray, CT, or fluoroscopic imaging, enabling unobstructed monitoring of callus formation and bone alignment at every follow-up visit
• Reduced soft tissue irritation — single-sided frame minimizes pressure points and soft tissue contact compared to ring fixators
• Lighter weight — reduces patient fatigue and enhances compliance with rehabilitation protocols

The G1320-B’s design philosophy is that the best fixator is the one patients successfully wear for the entire treatment duration.

Modular Architecture for Clinical Flexibility

No two limb reconstruction cases are identical. The G1320-B’s modular component system accommodates this variability without requiring custom implants:

• Variable bar lengths adapt to different bone segment dimensions
• Modular pin clamps accommodate bone diameters from tibia to humerus to radius
• Compatible with standard bone traction pins across multiple diameters
• System supports both simple lengthening protocols and complex bone transport sequences

This modularity also simplifies hospital stocking — a single G1320-B system can address a wide range of reconstruction procedures.

Complete Surgical Kit — No Supplementary Orders

Each G1320-B ships as a complete, ready-to-use surgical kit:

• 1× LRS B monolateral bone lengthening fixator main frame (distraction unit integrated)
• 4× Φ6.0×150mm bone traction pins for secure multi-point bone anchoring
• 1× 6mm Allen wrench for clamp tightening and frame adjustment
• 1× Φ6mm T-wrench for torque-controlled pin insertion and removal

All instruments required for intraoperative pin placement, frame assembly, and postoperative management are included. No supplementary procurement is necessary.

Clinical Indications

The G1320-B is suited for:

• Pediatric limb length discrepancy: Congenital, developmental, or post-traumatic shortening in children and adolescents
• Adult limb reconstruction: Moderate limb length discrepancy correction, post-fracture shortening
• Bone transport: Segmental bone defect bridging following infection, tumor resection, or traumatic bone loss
• Nonunion with shortening: Stimulating bone regeneration while correcting limb length
• Tibia and humerus lengthening: Primary anatomical targets for the 4-pin configuration
• Congenital and acquired long bone deformity correction: Combined angular deformity and limb shortening in both pediatric and adult patients
