The TOOLMED TLIF Peek Cage is specifically engineered for Transforaminal Lumbar Interbody Fusion, a procedure that allows for unilateral access to the disc space while minimizing dural retraction. This cage is crafted from PEEK-OPTIMA®, a biocompatible polymer known for its radiolucency and bone-like modulus of elasticity. The TLIF cage features a distinct tapered leading edge (bullet nose) to facilitate self-distraction and easy insertion into the collapsed disc space. Its anatomical biconvex shape and specialized tooth pattern provide immediate structural stability and resist migration. With a large internal graft window, the cage promotes robust osseointegration. Integrated tantalum markers ensure high-precision radiographic tracking, making the TOOLMED TLIF Cage a premier choice for surgeons aiming to restore sagittal balance and achieve successful fusion through a minimally invasive or open transforaminal approach.

Product Description
The leading edge is precision-tapered to allow for easier insertion and "self-distraction" of the vertebral bodies, reducing the need for excessive force and protecting the vertebral endplates.
Available in various lordotic angles, the cage helps surgeons restore the natural curvature of the lumbar spine, which is critical for long-term clinical success and reducing adjacent segment stress.
The PEEK material's modulus of elasticity minimizes the stiffness mismatch between the implant and bone, effectively preventing "stress shielding" and reducing the risk of cage subsidence.
The footprint is specifically designed to be delivered through a unilateral transforaminal window, requiring less retraction of the thecal sac and nerve roots compared to posterior approaches.
Specifically indicated for stabilizing segments where one vertebra has slipped forward. The TLIF approach allows for the restoration of disc height and stabilization while minimizing nerve root manipulation.
Used in patients with spinal canal narrowing. The cage provides indirect decompression of the neural foramen by distracting the intervertebral space, alleviating the symptoms of neurogenic claudication.
Indicated for revision surgeries where previous discectomy has led to instability. The TLIF cage provides the structural support needed to achieve permanent fusion in a previously compromised segment.
Applied in the correction of adult spinal deformity. Multiple TLIF cages can be used across several levels to correct coronal and sagittal imbalance by restoring asymmetric disc heights.

The TLIF Peek Cage is a structural interbody spacer designed specifically for Transforaminal Lumbar Interbody Fusion. It is inserted into the lumbar disc space via a unilateral approach through the neuroforamen. Made from PEEK-OPTIMA®, it provides the mechanical strength required for weight-bearing while maintaining a modulus of elasticity close to human bone, which is essential for preventing stress shielding and promoting a successful biological fusion.
This cage is widely applied in the surgical treatment of lumbar degenerative disorders, including spondylolisthesis and degenerative disc disease. Its unilateral insertion technique makes it ideal for both traditional open surgery and Minimally Invasive Surgery (MIS) approaches, as it significantly reduces the amount of tissue dissection and neural retraction needed compared to bilateral procedures.
The TOOLMED TLIF Cage offers the distinct advantage of radiolucency, allowing for clear assessment of bone growth on post-op X-rays. Its tapered leading edge makes insertion smoother in collapsed discs, while the aggressive unidirectional serrations ensure the cage remains securely in place. The various lordotic angles available allow surgeons to customize the restoration of lumbar alignment to each patient's specific anatomy.
Biomechanically, the TLIF cage acts as a load-sharing spacer for the anterior and middle columns of the spine. By supporting the vertebral endplates across a wide surface area, it resists subsidence and maintains the distraction of the disc space. This stability is crucial for ensuring that the bone graft packed within and around the cage can undergo osteoconduction without mechanical disruption.
Through a transforaminal approach, the disc space is cleared and the endplates are prepared to encourage vascularization. A trial is used to verify the footprint and lordosis. The TLIF Peek Cage is then filled with bone graft and inserted using a dedicated impactor. The "bullet nose" guides the cage into the center of the disc space. Integrated tantalum markers allow the surgeon to confirm the cage is optimally recessed before applying posterior pedicle screw fixation.
Post-surgical care involves monitoring the patient's return to mobility, often facilitated by physical therapy. A lumbar brace may be used to protect the fusion site during the first 6–12 weeks. Because PEEK is non-metallic and MRI-safe, postoperative imaging is highly effective for monitoring nerve root health and the maturing fusion bridge without the risk of image distortion or metal-induced artifacts.
The TOOLMED TLIF Peek Cage provides an advanced, biologically compatible solution for achieving lumbar fusion. Its anatomical design and superior material properties ensure that surgeons can restore spinal height and alignment with precision, providing patients with a reliable path to long-term recovery.
Yes, the bullet-nose design and unilateral insertion footprint are specifically optimized for MIS TLIF approaches using tubular retractors.
PEEK is radiolucent (invisible on X-ray). The tantalum markers act as reference points so the surgeon can verify the cage's exact depth and center-line orientation during surgery.
Yes, the PEEK-OPTIMA material is engineered for high fatigue resistance, and its bone-like modulus helps prevent the cage from sinking into the vertebrae, maintaining disc height long-term.
In most clinical cases, the TLIF cage is used in conjunction with posterior pedicle screw fixation to ensure the rigid environment necessary for a successful 360-degree fusion.
We provide 0°, 4°, and 8° lordotic angles to help surgeons restore the natural inward curve (lordosis) of the patient's lumbar spine.
