Some pelvic injuries resist categorization. They combine elements of rotational instability, vertical shear, and multiplanar displacement that exceed what standard or triaxial fixators can address. For these cases, Amis Orthopedic developed the G1120-C Multiaxial Pelvic External Fixator — a premium fixation system with 360° multiplanar ball-and-socket joints that give surgeons unrestricted freedom of adjustment in any direction, at any angle, at any stage of the procedure.
No Limits on Correction
The G1120-C operates on a different design principle than conventional pelvic fixators. Where standard and triaxial systems constrain movement to discrete axes, the G1120-C’s full-range ball-and-socket articulation allows continuous adjustment throughout the entire sphere of motion. This means:
- No need to choose between planes — adjust in multiple directions simultaneously
- Fine-tune reduction at any angle without unlocking and repositioning the construct
- Accommodate unusual fracture geometries and anatomical variations that defy standardized correction sequences
For the most complex pelvic ring disruptions — high-energy crashes, crush injuries, combined anterior and posterior instability — the G1120-C delivers the precision that optimal outcomes require.

Advanced Articulation Mechanism — The Engineering Behind the Control
The G1120-C’s articulation system is engineered for both freedom and rigidity. Each ball-and-socket joint is designed to:
- Move freely during reduction — allowing fine adjustment without resistance or mechanical binding
- Lock completely when tightened — eliminating micro-motion once the correct position is achieved
- Maintain lock under load — retaining the corrected position through patient movement, transport, and progressive weight-bearing
The joint locking mechanism is controlled by a 10mm combination wrench — included in the kit — which provides the torque required for secure, durable locking of high-complexity joint configurations. This additional tool distinguishes the G1120-C from simpler fixators that cannot generate adequate locking force at multi-directional joint positions.
Reinforced Frame for High-Energy Injuries
High-energy pelvic injuries generate substantial disrupting forces. The G1120-C’s robust, modular aluminum alloy frame with reinforced joint connections is specifically rated for these demanding mechanical environments.
The reinforced connection points resist the twisting and shear loads that characterize severe pelvic trauma, ensuring the construct maintains reduction without progressive loosening during the weeks of fixation. This level of biomechanical durability is a prerequisite for cases that cannot tolerate loss of reduction — such as combined pelvic and abdominal injuries being managed simultaneously.
Comprehensive Tool Kit for Full Clinical Control
The G1120-C ships with a three-piece instrument set that covers every intraoperative and postoperative adjustment need:
- 6mm Allen wrench — standard clamp tightening and frame fine-tuning
- Φ6mm T-wrench — controlled insertion and torque-limited removal of bone traction pins
- 10mm combination wrench — high-torque locking of the multiaxial ball joints
No additional instruments are required. This complete kit reduces pre-operative preparation time and eliminates the risk of missing tools during the procedure.
Clinical Indications
The G1120-C is specifically indicated for:
- Severe and complex pelvic ring disruptions with multiplanar instability (OTA/AO Type C and selected severe Type B)
- High-energy pelvis injuries requiring maximum fixation freedom for anatomical reduction
- Complex cases where standard or triaxial fixators do not provide adequate correction range
- Revision pelvic fixation where initial reduction has failed
- Definitive external fixation in patients with contraindications to internal fixation
- Combined pelvic fixation in complex polytrauma cases
