JUPITER, FL – July 2026 — The EquiLOX Expandable Lumbar Cage System is a TLIF and PLIF expandable lumbar cage designed around a practical workflow from implant sizing through post-expansion graft delivery. Its expandable titanium construction, minimal starting height, lordotic options, and backfilling capability support a streamlined approach to posterior lumbar interbody fusion procedures.
Captiva Spine, Inc. continues to highlight EquiLOX as an expandable lumbar interbody solution designed to maximize expansion without sacrificing through-cage fusion area. The system is built around a straightforward four-step procedural sequence:
Size. Insert. Expand. Backfill.
The EquiLOX expandable lumbar cage features a minimal starting height, tapered leading edge, distal expansion mechanism, and post-expansion backfilling capability. Together, these features support an efficient workflow from implant selection and insertion through controlled expansion and graft delivery.
A Streamlined Expandable Lumbar Cage Workflow
The EquiLOX™ workflow begins with selecting the appropriate implant dimensions for the surgical plan. The expandable lumbar cage is then inserted at its starting height before being expanded within its designated height range.
Following expansion, compatible flowable bone graft material can be delivered through a small cannula to backfill the implant. This sequential approach connects the primary procedural steps within one coordinated workflow:
- Size the implant based on the surgical plan.
- Insert the expandable lumbar cage at its minimal profile.
- Expand the implant within its designated height range.
- Backfill the implant with compatible graft material.
This workflow is intended to provide a practical transition from implant placement through graft delivery without sacrificing the large through-cage fusion area.
Controlled Expansion and Post-Expansion Backfilling
EquiLOX incorporates a distal expansion mechanism that provides controlled, variable height adjustment. The 7mm expandable lumbar cage provides 4mm of expansion, reaching a maximum height of 11mm. All other available options provide up to 5mm of variable expansion.
The implant’s design preserves an open through-cage area following expansion. This allows compatible flowable bone graft material processed to pass through small cannulas to be delivered after the cage has been positioned and expanded.
Post-expansion backfilling is integrated into the EquiLOX workflow rather than treated as a separate procedural consideration. The result is a clear progression from sizing and insertion to expansion and graft delivery.
“EquiLOX was developed around a straightforward TLIF/PLIF workflow,” said Dale Mitchell, President of Captiva Spine. “The system gives surgeons a practical sequence from sizing and insertion to expansion and backfilling.”
EquiLOX Expandable Lumbar Cage Sizes
The EquiLOX TLIF and PLIF expandable lumbar cage is available in a 10mm width with 24mm and 28mm length options. Available starting heights range from 7mm to 12mm, with expanded heights ranging from 11mm to 17mm, depending on the selected implant.
The current offering includes 3°, 6°, and 9° lordotic options. Custom 12° and 15° options are also available upon request.
24mm Length x 10mm Width
- 7mm to 11mm height, 3° lordosis
- 8mm to 13mm height, 3° lordosis
- 9mm to 14mm height, 6° lordosis
- 10mm to 15mm height, 9° lordosis*
- 11mm to 16mm height, 12° lordosis*
- 12mm to 17mm height, 15° lordosis*
28mm Length x 10mm Width
- 7mm to 11mm height, 3° lordosis*
- 8mm to 13mm height, 3° lordosis
- 9mm to 14mm height, 6° lordosis
- 10mm to 15mm height, 9° lordosis
- 11mm to 16mm height, 12° lordosis*
- 12mm to 17mm height, 15° lordosis*
*Custom options available upon request.
The 7mm cage expands 4mm to a maximum height of 11mm. All other options provide up to 5mm of variable expansion.
Lordotic Expandable Lumbar Cage Options
The EquiLOX system provides multiple lordotic profiles across its available implant sizes. The standard offering includes 3°, 6°, and 9° options, depending on the selected implant configuration. Custom 12° and 15° lordotic options are available upon request.
These options allow the implant dimensions and lordotic profile to be selected according to the surgical plan. The available range also provides surgeons and facilities with a defined selection of expandable lumbar cage configurations within a single procedural system.
Supporting TLIF and PLIF Procedures
TLIF and PLIF procedures may require implant options that accommodate the selected surgical approach, the available disc space, and the planned implant dimensions. EquiLOX begins with a minimal insertion profile and provides variable expansion after placement.
The tapered leading edge and available 7mm starting height are designed to support implant insertion. Once positioned, the cage can be expanded within the range specified for that implant. Its distal expansion mechanism preserves access to the through-cage area for subsequent graft delivery.
Expandable lumbar cage technology is also discussed throughout the clinical literature in relation to posterior lumbar interbody fusion procedures. A peer-reviewed review available through the National Institutes of Health provides additional background on the designs and use of expandable cages in lumbar interbody fusion.
Expandable Titanium Construction
EquiLOX™ incorporates expandable titanium construction with a large graft window and through-cage fusion area. The implant is designed to provide expansion while maintaining space for compatible graft material.
The system brings together several procedural features within one expandable lumbar interbody platform:
- Minimal starting height
- Tapered leading edge
- Controlled distal expansion
- Variable height adjustment
- Multiple lordotic profiles
- Large through-cage area
- Post-expansion backfilling
- 24mm and 28mm length options
These features reflect Captiva Spine’s continued focus on practical lumbar interbody solutions for modern spine procedures.
Captiva Spine continues to expand access to the EquiLOX Expandable Lumbar Cage System for TLIF and PLIF procedures. To learn more about EquiLOX™ or discuss availability, contact Captiva Spine at info@captivaspine.com.
