LRS A Bone Lengthening Fixator G1310-A

Long-distance bone lengthening places extraordinary demands on both patient and hardware. The longer the lengthening, the longer the frame must hold — resisting loosening, malalignment, and mechanical fatigue across months of treatment. The G1310-A LRS A Bone Lengthening Fixator by Amis Orthopedic meets this challenge with a 6-pin anchoring configuration that delivers the enhanced rigidity and multi-point bone stability that extended lengthening cases require.

Why 6 Pins Changes the Equation

Standard LRS bone lengthening systems typically use 4-pin configurations. The G1310-A uses 6 bone traction pins — and that difference is clinically significant. Multi-point bone anchoring distributes mechanical loads more evenly along the frame, reducing stress concentration at individual pin sites. The practical benefits include:

• Lower risk of pin loosening over long treatment durations
• Reduced frame flex during weight-bearing and rehabilitation activities
• Greater resistance to malalignment in demanding lengthening scenarios (e.g., femoral lengthening in heavier adult patients)
• Improved suitability for longer lengthening distances where standard 4-pin systems may show progressive mechanical degradation

For orthopedic surgeons managing limb length discrepancies requiring more than 5–6cm of lengthening, adult femoral reconstruction cases, or patients with higher body mass, the 6-pin design of the G1310-A is the preferred choice.

Controlled Distraction Osteogenesis — Precision at Every Millimeter

The G1310-A is built around a linear screw-driven distraction mechanism that allows precise, incremental bone lengthening. Standard protocols advance distraction at approximately 1mm per day (typically divided into 4 × 0.25mm adjustments), though surgeons can customize the rate based on callus quality observed on radiographic follow-up.

Key distraction mechanism features:

• Clear scale markings on the distraction rod for accurate progress tracking
• Smooth, uniform force delivery that minimizes spike loading at the regenerate bone zone
• Surgeon-adjustable protocol — easily modified for faster or slower distraction based on bone formation response
• External adjustment — all distraction increments performed by the patient or caregiver outside the hospital, eliminating frequent clinical visits

This level of controlled precision is essential for minimizing risks of premature consolidation, joint contracture, and neurovascular compromise during the lengthening phase.

Low-Profile Monolateral Design Preserves Patient Quality of Life

Extended limb reconstruction — sometimes lasting 6–18 months — demands a fixator that patients can actually live with. The G1310-A’s monolateral (single-sided) frame construction keeps the hardware profile low and the limb accessible:

• No circumferential frame obstruction — patients can dress, bathe, and manage daily activities more comfortably than with circular Ilizarov frames
• Radiolucent-compatible profile — does not obstruct X-ray, CT, or MRI imaging planes, allowing unimpeded monitoring of callus formation and bone alignment throughout treatment
• Reduced soft tissue irritation compared to bulkier bilateral constructs
• Lighter overall system weight reduces patient fatigue during prolonged fixation

Complete Surgeon-Friendly Kit

The G1310-A ships with every instrument required for intraoperative setup and postoperative management:

• 1× LRS A monolateral bone lengthening fixator main frame (distraction unit integrated)
• 6× Φ6.0×150mm medical-grade stainless steel bone traction pins
• 1× 6mm Allen wrench — for clamp tightening, distraction mechanism adjustment, and frame fine-tuning
• 1× Φ6mm T-wrench — for torque-controlled pin insertion and removal

No supplementary ordering is required. From the first incision to final pin removal, the G1310-A kit has the tools your team needs.

Clinical Applications

The G1310-A system is designed for a broad range of limb reconstruction indications:

• Congenital limb length discrepancy: Femoral deficiency, hemihypertrophy, and developmental dysplasia requiring staged lengthening
• Post-traumatic lengthening: Bone transport for segmental defects, malunion correction with lengthening, nonunion with shortening
• Adult femoral lengthening: Cases requiring higher fixation strength due to patient size or extended lengthening distance
• Deformity correction with lengthening: Combined angular/rotational deformity and limb shortening
• Bone defect reconstruction: Defects secondary to infection, tumor resection, or severe fracture comminution
• Long bone stabilization with planned lengthening: Temporary fracture stabilization followed by bone transport
