Intended Use

The Toro-L Interbody Fusion System is indicated for intervertebral body fusion of the spine in skeletally mature patients. The system is designed for use with autogenous and/or allogeneic bone graft comprised of cancellous and/or cortical cancellous bone graft to facilitate fusion and supplemental internal spinal fixation systems (e.g., pedicle screw/rod systems) cleared by the FDA for use in the thoracolumbar spine. The devices are to be used in patients who have had at least six months of non-operative treatment. The Toro-L Interbody Fusion System is interbody fusions in the thoracic spine from T1 to T12 and at the thoracolumbar junction (T12-L1), and is intended for use in the lumbar spine, from L1 to S1, for the treatment of symptomatic disc degeneration (DDD) or degenerative spondylolisthesis at one or two adjacent levels, including thoracy disc herniation (with myelopathy with or without axial pain). DDD is defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies. The Toro-L Interbody Fusion System can be used as an adjunct to fusion in patients diagnosed with multilevel degenerative scollosis.

Device Story

Toro-L Interbody Fusion System consists of bi-directional expandable and non-expandable monolithic interbody fusion implants; used for spinal fusion in thoracic and lumbar regions. Implants inserted via lateral surgical approach; restore disc height; provide anterior column support; maintain structural stability. Expandable version features integrated ramps for insertion in non-expanded state, then expanded to desired height/width; locking mechanism secures configuration; post-packed with bone graft. Monolithic version is conventional spacer with dual compartments for bone graft. Both designs include bullet-nosed tips and surface protrusions to resist expulsion. System includes manual surgical instruments for delivery and disc preparation. Used by surgeons in clinical settings; requires user-performed steam sterilization. Benefits patients by facilitating fusion in degenerative spine conditions.

Clinical Evidence

Bench testing only. Testing included static and dynamic axial compression and static and dynamic compression shear per ASTM F2077. Biocompatibility assessment conducted per ISO 10993-1.

Technological Characteristics

Materials: Titanium alloy (Ti-6Al-4V ELI per ASTM F136, Ti-6Al-4V per ASTM F2924) and PEEK (ASTM F2026). Configurations: Bi-directional expandable and monolithic non-expandable.

Indications for Use

Indicated for skeletally mature patients requiring intervertebral body fusion in thoracic (T1-T12), thoracolumbar (T12-L1), and lumbar (L1-S1) spine. Treats symptomatic disc degeneration (DDD), degenerative spondylolisthesis (1-2 levels), thoracic disc herniation, and multilevel degenerative scoliosis. Requires 6 months prior non-operative treatment. Used with autogenous/allogeneic bone graft and supplemental internal fixation.

Regulatory Classification

Identification

An intervertebral body fusion device is an implanted single or multiple component spinal device made from a variety of materials, including titanium and polymers. The device is inserted into the intervertebral body space of the cervical or lumbosacral spine, and is intended for intervertebral body fusion.

Special Controls

*Classification.* (1) Class II (special controls) for intervertebral body fusion devices that contain bone grafting material. The special control is the FDA guidance document entitled “Class II Special Controls Guidance Document: Intervertebral Body Fusion Device.” See § 888.1(e) for the availability of this guidance document.(2) Class III (premarket approval) for intervertebral body fusion devices that include any therapeutic biologic (e.g., bone morphogenic protein).

#### VIII. Summary of Technological Characteristics

The subject Toro-L Interbody Fusion System implants are manufactured from titanium alloy (Ti-6Al-4V ELI per ASTM F136 and Ti-6Al-4V per ASTM F2924) and polyether ether ketone (PEEK) per ASTM F2026; and are offered in a range of sizes and lordotic options to accommodate variations in patient anatomy.

The Toro-L Interbody Fusion System expandable implant has integrated ramps that allow the implant to be inserted in a non-expanded form, and then subsequently expanded to full width and desired height through continuous expansion. When the desired implant height is achieved, the locking system is engaged to secure the construct in its final expanded configuration. The implant is then post-packed with bone graft. The design includes a bullet-nosed tip to aid in insertion into the disc space, and teeth on the superior and inferior surfaces to resist expulsion.

The monolithic implant is a non-expanding conventional spacer with the interior space of the device divided into two compartments for bone graft containment.

Both the expandable and monolithic configurations have protrusions on the superior and inferior surfaces of the endplates of the implant to grip the adjacent vertebral endplates to resist expulsion.

The subject implant and instruments are offered non-sterile and are intended to be steam sterilized by the user prior to use.
