The Posterior ALIF®
Delivering the Benefits of an ALIF from a Posterior Approach
- Achieves sagittal alignment through height expansion and various degrees of lordotic options
- Stabilizes the spine through footprint expansion that delivers market-leading endplate coverage
- Preserves radiographic visualization of an ALIF-comparable fusion area while the titanium surface promotes osteoblast attachment
- Delivered via posterior approach with a 7mm insertion height while preserving the ALL
Effective, Efficient Disc Prep
Orbit® − Clearing the path for the largest TLIF implant
- Facilitates an efficient circumferential discectomy, reducing surgical time while creating a wide fusion footprint
- Instrument tips easily reach contralateral disc space
- Rotating shavers debulk large volumes of disc
- Minimizes instrument passes near vital neural elements
Restores Alignment with Maximum Stability
- Statistically significant restoration of disc height and neuroforaminal height1
- Multi-dimensional interbody options to restore lordosis1,2
- Biomechanical data shows that segmental motion was equivalent to ALIF cages3
- Creates a stable base for long constructs
Designed for Fusion
- Clinically proven to resist long-term subsidence1,2*
- Guided graft delivery for maximum packing capability
- Fusion rates from two different studies show 93.3% at 1 yr and 98% at 2 yrs1,2*
- Titanium integrated surface creates favorable fusion environment, while retaining imaging properties of PEEK
- Engineered to address the unique fusion demands of L5/S1
