Triaxial Pelvic External Fixator G1110-B

Complex pelvic ring injuries rarely fail in just one plane. Rotational instability, posterior ligamentous disruption, and vertical shear patterns demand a fixator that operates in three dimensions — not one. The G1110-B Triaxial Pelvic External Fixator by Amis Orthopedic delivers precisely that: simultaneous adjustment in the sagittal, coronal, and axial planes, giving surgeons complete spatial control over pelvic ring reduction.

Three Axes. One Frame.

The defining feature of the G1110-B is its triaxial multi-directional articulation system. Each joint in the frame provides independent movement in a specific anatomical plane:

• Sagittal plane — anterior-posterior tilt correction
• Coronal plane — medial-lateral displacement control
• Axial plane — rotational and translational adjustment

This 3-axis architecture allows the surgeon to isolate and correct each component of a complex pelvic deformity individually, achieving a quality of reduction that single-axis systems simply cannot match. For Type B and Type C pelvic ring injuries where anatomical reduction is critical for long-term functional outcomes, the G1110-B is the appropriate tool.

Enhanced Biomechanical Stability for Unstable Injuries

Unstable pelvic fractures generate significant disrupting forces — shear, rotation, and distraction — that standard external fixators may not fully neutralize. The G1110-B addresses this with a high-rigidity, lightweight medical-grade aluminum alloy frame reinforced at every joint connection.

The triaxial clamps lock independently at each axis, allowing the surgeon to secure each plane of correction sequentially without losing position in already-corrected planes. The final locked construct is mechanically rigid — appropriate for immediate patient positioning, transport, and early mobilization protocols.

Surgical Workflow Optimized for Complexity

Despite its advanced adjustment capabilities, the G1110-B is designed to remain operable under time pressure. Key design choices support an efficient intraoperative workflow:

• Quick-lock clamp mechanism — each axis locks with a single Allen wrench turn
• Standardized HB Φ6.0×150mm bone screws — compatible with standard pelvic pin insertion guides and instruments
• Modular frame components — allow configuration adjustment to patient anatomy without requiring custom parts
• Intuitive joint design — clear axis markings prevent confusion between planes during adjustment

The complete kit includes both the 6mm Allen wrench and the Φ6mm T-wrench, covering all intraoperative and postoperative adjustment needs.

Appropriate for Advanced Trauma Protocols

The G1110-B fits naturally into modern pelvic trauma management pathways. Its application scope includes:

1. Primary stabilization of complex Type B and Type C pelvic ring injuries requiring 3-plane correction
2. Staged treatment — applied as the definitive external fixator following initial DCO stabilization
3. Adjunct to internal fixation — maintains external pelvic alignment while posterior ring internal fixation (sacroiliac screws, posterior plating) is performed
4. Long-term external fixation in patients where internal fixation is contraindicated (infection, severe soft tissue damage, medical comorbidity)

Clinical Indications

• Complex, rotationally and vertically unstable pelvic ring disruptions (OTA/AO Type B and C)
• Multi-plane pelvic fractures requiring independent sagittal, coronal, and axial correction
• High-energy pelvic injuries with posterior ligamentous involvement
• Cases requiring precise anatomical reduction with progressive fine-tuning
• Pelvic fractures in patients requiring staged surgical management

Technical Specifications

Quality and Regulatory Information

The G1110-B is manufactured by Amis Orthopedic under strict international quality standards, with mechanical testing of all articulating joints, fatigue cycle validation, and sterilization compatibility verification. Hospitals and distributors can request full technical files and biocompatibility documentation for local regulatory registration purposes.

Precision Matters When the Pelvis Is Unstable

The G1110-B Triaxial Pelvic External Fixator was built for the cases where a standard fixator is not enough. When your patient’s pelvic ring needs correction in three planes, this is the system that delivers. Advanced adjustability. Clinical reliability. Backed by Amis Orthopedic’s manufacturing quality.
