Lumbar interbody fusion cage 111010

anteriorPEEK

Product Introduction
The Uni‑L self-stabilizing lumbar interbody fusion cage (insert-type, model 111010) is a PEEK interbody implant incorporating pure tantalum radiopaque markers and two titanium-alloy locking clips. Available in multiple footprints and heights, the device is placed between adjacent lumbar vertebral bodies and secured with a dual-clip self-locking mechanism. Its distraction-compression stabilization design generates opposing forces to resist shear and rotation while transferring axial loads. The system provides immediate postoperative segmental stability, supports restoration of disc height and lumbar lordosis, and includes a hollow internal chamber for bone graft material to support fusion.

Features

• Immediate fixation & height restoration: Vertical locking clips engage adjacent vertebrae to limit micromotion and reduce implant migration risk.
• Zero-profile design: Contained fully within the disc space to minimize soft tissue irritation and adjacent-segment interference.
• Serrated endplates: Serrations improve frictional purchase on vertebral endplates for initial mechanical stability.
• Radiopaque markers: Integrated pure tantalum markers facilitate intraoperative positioning and postoperative imaging.
• Bone-mimetic elastic modulus: PEEK’s modulus closer to cancellous bone helps reduce stress shielding and supports osseous integration.
• High fatigue resistance: Engineered to withstand long-term axial loading during the fusion period.
• Imaging compatibility: Radiolucent PEEK enables clear X-ray and MRI with minimal artifact; tantalum markers provide clear reference points.
• Secure clip locking: Two titanium-alloy locking clips deliver dependable fixation and resist back-out.

Advantages

• Minimally invasive insertion: reduced cage profile facilitates insertion through smaller incisions using dedicated instruments to set clip depth.
• Customizable sizing: multiple footprints and heights to fit patient anatomy and surgical requirements.
• Standalone option: zero-profile, self-stabilizing design may obviate posterior instrumentation in selected cases.
• Clear postoperative assessment: tantalum markers aid radiographic follow-up.
• Clip-only stabilization: vertical clip deployment secures the implant while minimizing posterior soft-tissue disruption.

Indications

• Single- or multi-level lumbar anterior interbody fusion
• Spinal instability
• Revision procedures following posterior discectomy
• Degenerative disc disease
• Pseudarthrosis
• Scoliosis
