TLIF and Robotic TLIF Surgery
A planned lumbar fusion pathway for selected patients with nerve compression, instability, disc collapse or recurrent leg and back symptoms.
Transforaminal lumbar interbody fusion, often called TLIF, is a spine surgery that approaches the disc space from one side of the back to decompress nerves, place an interbody cage and stabilize the segment with screws and rods.
At Apteum Spine, evaluation starts with your imaging, neurologic exam, prior treatment history and goals. Minimally invasive TLIF or robotic TLIF may be considered when it fits your anatomy and diagnosis.

COORDINATED LUMBAR FUSION PLANNING
One evaluation focused on the real question: is fusion the right next step for you?
TLIF is not a first step for every back-pain problem. Apteum’s process is designed to determine whether symptoms, imaging and prior treatment support a fusion procedure—or whether decompression alone, injections, therapy, medication changes, observation or another approach may be more appropriate.
Diagnosis before technique
The conversation starts with what is causing the pain or nerve symptoms, not with choosing hardware or a robot.
Individual surgical planning
If TLIF is reasonable, the plan considers level, side of approach, decompression needs, cage strategy, fixation, bone quality and prior surgery.
Robotics when appropriate
Robotic navigation may assist pedicle screw planning and guidance. It is a tool used selectively, not a guarantee and not the only way to perform accurate spine surgery.
Who may need a TLIF evaluation?
A TLIF evaluation is often considered when lumbar nerve compression and mechanical instability or disc collapse overlap. The goal is to understand whether decompressing the nerves and stabilizing the segment may be appropriate for your specific condition.
Problems that may prompt TLIF discussion
- Leg pain from nerve compression. Sciatica, radiculopathy, numbness or weakness linked to foraminal stenosis, recurrent disc problems or collapsed disc space.
- Spondylolisthesis or instability. Slippage or abnormal motion that may require stabilization in addition to nerve decompression.
- Degenerative disc collapse with stenosis. Loss of disc height that narrows the nerve exit passage and contributes to back and leg symptoms.
- Selected revision situations. Prior lumbar surgery with recurrent compression, scar, instability or structural problems that need careful imaging review.
What TLIF does — and does not do
TLIF is designed to decompress selected nerves and stabilize a lumbar spinal segment using an interbody cage, bone graft material and screw-rod fixation.
It does not treat every cause of back pain, does not reverse all nerve damage, and does not guarantee pain relief or fusion success. Your evaluation should separate nerve compression, instability, hip or vascular problems, neuropathy and other pain generators.
A stepwise pathway from imaging review to surgical decision.
TLIF planning combines diagnosis, patient goals, anatomy, risk assessment and alternatives. If surgery is appropriate, the operation may be open, minimally invasive or robot-assisted depending on the case.
Transforaminal lumbar interbody fusion
TLIF approaches the disc space through a posterior, one-sided corridor. The surgeon can remove pressure from nerves, prepare the disc space and place an interbody cage to support the segment.
Minimally invasive TLIF
In selected patients, a smaller muscle-sparing approach may be used. Suitability depends on anatomy, level, prior surgery, body habitus, deformity, instability and the amount of decompression needed.
Robotic TLIF
Robotic navigation may assist with preoperative planning and intraoperative guidance for pedicle screw trajectories. The surgeon remains responsible for the plan and the procedure.
Your TLIF evaluation and treatment pathway
A decision at each stage. A plan that should fit your diagnosis, not just the name of a procedure.
- 1
Identify the pain generator
Review symptoms, physical exam, MRI/CT/X-rays and prior treatment to determine whether nerve compression, instability, disc collapse or another condition is driving symptoms.
- 2
Compare alternatives
Discuss whether nonsurgical care, injection-based care, decompression alone, disc replacement, a different fusion approach or continued monitoring may be better suited to your case.
- 3
Plan the decompression and fusion
If TLIF is appropriate, plan the surgical level, side of approach, nerve decompression, disc-space preparation, interbody cage position, graft strategy and screw-rod fixation.
- 4
Use navigation or robotics when it fits
For robotic TLIF, 3D imaging and navigation can support surgeon-planned screw trajectories and rigid robotic guidance. The surgeon verifies anatomy and makes clinical decisions throughout.
- 5
Perform decompression, cage placement and fixation
The operation typically includes removing pressure from nerves, preparing the disc space, placing an interbody cage with graft material and stabilizing the level with screws and rods.
- 6
Recover and monitor healing
Recovery planning may include wound care, activity restrictions, walking progression, physical therapy timing, medication review, imaging follow-up and monitoring for fusion and neurologic improvement.
If TLIF is not the right fit
The evaluation can still be valuable. Apteum may recommend continued nonsurgical care, pain-management options, a different surgical strategy, updated imaging or a second-opinion review before any operation is planned.
Bring records when possible: MRI/CT/X-ray images and reports, operative reports, injection notes, therapy records, medication list, medical conditions, nicotine history and any prior fusion or hardware details.

Robotic precision: a planned path for every screw
Robotic TLIF translates a surgeon-created plan into the operating room with 3D imaging, rigid robotic guidance and real-time navigation. Each planned screw trajectory is selected for the patient’s anatomy and checked during surgery.
How the planning works
- 3D imaging supports planning. CT-based or intraoperative imaging can help map bony anatomy and spinal alignment.
- The surgeon plans trajectories. Screw paths are selected based on anatomy, level, bone corridors, hardware goals and the overall fusion plan.
- Rigid robotic guidance assists alignment. The robotic arm helps guide instruments along the planned path while the surgeon controls the operation.
- Navigation provides spatial feedback. Real-time navigation helps the team relate instruments to the patient’s anatomy during the procedure.
Published accuracy with ExcelsiusGPS
98.0%
A 2024 systematic review reported a weighted 98.0% rate of Gertzbein–Robbins grade A or B pedicle screws for ExcelsiusGPS (95% CI 97.2%–98.6%). Grade A or B describes no breach or a breach under 2 mm; it does not mean every screw precisely matched the planned path.
The review included 46 studies across four robotic systems. These are published screw-placement results, not Apteum outcomes or a personal probability of pain relief.

What the accuracy evidence means for your care
Robotic guidance brings the surgeon’s planned trajectory, rigid instrument alignment and navigation feedback together during screw placement. Published comparative studies support high accuracy and improved placement versus fluoroscopy-guided techniques.
Accurate placement remains possible with other accepted techniques. Robotics assists the operation; diagnosis, surgical judgment, anatomy and bone healing still determine the overall result.

PEDICLE SCREW ACCURACY EVIDENCE
Robotic assistance vs fluoroscopy-guided techniques
A 2024 meta-analysis of 12 randomized controlled trials reported higher pedicle screw placement accuracy with robot-assisted techniques compared with conventional fluoroscopy-guided techniques.
The same analysis reported similar complications, radiation exposure time and operative duration between groups. This describes study populations and techniques, not Apteum-specific results.
Globus ExcelsiusGPS technology
ExcelsiusGPS is described by Globus Medical as a platform that combines navigation and robotic guidance for spine procedures. System capabilities should be discussed in the context of your anatomy, imaging and surgical plan.

Accuracy is not the same as outcome guarantee
Pedicle screw placement accuracy is an important technical endpoint. Pain relief, neurologic recovery, fusion healing and return to activity depend on diagnosis, decompression, biology, bone quality, smoking/nicotine status, medical conditions, rehabilitation and other factors.
Do not interpret the odds ratio above as a personal probability of benefit. It is a study-level comparison of screw placement accuracy, not a guarantee of pain relief, fusion success or complication avoidance.
Request a telehealth or in-person TLIF evaluation.
