InFill®

Infill® direct lateral lumbar accomplishes this through its patented shape and groundbreaking approach for graft delivery.The key to solid fusion is to optimize graft contact with the vertebral endplates.

• The Pinnacle Spine Infill® Lateral Interbody Device features a unique access port that can be used for both placement in the disc space and in situ delivery of the precise amount of graft material.

• The distinctive tooth geometry in the larger, single graft chamber helps secure the graft material, whether it’s delivered in situ or through traditional pre-packing. In addition, the lateral implant has a soft bulleted nose for smooth, confident placement within the disc space, and a larger load bearing surface for restoring and maintaining disc height.

• In situ delivery of graft material ensures precision placement in the large graft chamber.

• Large graft chamber facilitates formation of a robust fusion column.

• Large load bearing surface area restores & maintains disc space and height.

• Bulleted tip provides ease of insertion & precise placement.

• Length ranging from 40mm to 60mm, heights ranging from 8mm to 14mm, parallel and lordotic (nominal 6 degrees of lordosis).

• Tantalum rod markers provide excellent radiographic visualization of implant orientation and placement.

About LLIF

The Lateral Lumbar Interbody Fusion (LLIF) procedure is a minimally disruptive surgical technique in which the surgeon approaches the spine from the side of the patient’s body, rather than the front or back as in traditional spine surgeries. This side (lateral transpsoas) approach can reduce the risk of injury to muscles, nerves, and blood vessels.

The XLIF and DLIF are  types Lateral Lumbar Interbody Fusion, or LLIF, which is a category of fusion in which the disc in the front of the spine is removed and replaced with an implant containing a bone graft to set up the condition for the two vertebrae to fuse together through the disc space.

XLIF uses a minimally invasive, transpsoas approach to the spine. The surgeon uses his or her finger to perform blunt dissection through a posterior paraspinal incision to escort dilators and a guide wire into position directly over the psoas muscle. Using his or her finger the surgeon is able to create a retroperitoneal space and protect the viscera and prevent possible injury.

With the DLIF technique, some surgeons have chosen to perform this procedure through a single miniopen lateral approach without the use of the posterior incision to create the retroperitoneal space. With the single incision, the layers of the abdominal wall are directly visualized, and the retroperitoneal space is created under direct vision with passage of instruments through the psoas. In addition, the use of electrophysiological monitoring, including triggered and freerunning electromyography (EMG), reduces the likelihood of injury to the lumbosacral plexus when accessing the disc space through the psoas muscle. Dilators, which contain insulated tips allow for EMG monitoring as they are introduced via the transpsoas approach to the disc space. If a dilator passes in proximity to the lumbosacral plexus, the surgeon is warned both visibly on a graphic display and also via auditory feedback. The surgeon can then adjust his or her trajectory to reduce the likelihood of neural injury.
