The AEGIS Anterior Lumbar Plate System is intended for use as an anteriorly placed supplemental fixation device via the lateral or anterolateral surgical approach above the bifurcation of the great vessel or via the anterior surgical approach, below the bifurcation of the great vessels. The device is intended as a temporary fixation device until fusion is achieved. The AEGIS Anterior Lumbar Plate System is intended for anterior lumbar (L1-S1) fixation for the following indications are:
• degenerative disc disease (ddd) defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies;
• spondylolisthesis;
• trauma (i.e., fracture or dislocation);
• deformities or curvatures (i.e., scoliosis, kyphosis, and/or lordosis);
• tumor;
• pseudarthrosis; and
• previous failed fusion.
The Anterior Dynamized system is intended for use in anterior decompression instrumentation and fusion for kyphotic deformities, post traumatic kyphotic deformities, degenerative disc disease (defined as discogenic and back pain with degeneration of the disc confirmed by history and radiographic studies), burst fractures, tumors and previous failed surgery of the spine. The intended levels for treatment range from T10 to L3.
The ISOLA Spine System when used as anterior thoracic/lumbar screw fixation system, is indicated for degenerative disc disease (defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies), spondylolisthesis, trauma (fracture and/or dislocation), spinal stenosis, deformities (scoliosis, lordosis and/or kyphosis), tumor, and previous failed fusion (pseudarthrosis).
The BOWTI Anterior Buttress Staple System, in conjunction with traditional rigid fixation, is intended for use in spinal fusion procedures as a means to maintain the relative position of weak bony tissue such as allografts or autografts. This device is not intended for load bearing applications.
The BOWTI Anterior Buttress Staple System is intended for anterior intravertebral body screw fixation/attachment to the T1-S1 spine over one vertebral body extending into the adjacent intervertebral space. Specifically, the device is intended for stabilization and buttressing of bone graft as an aid to spinal fusion. It may be used with other anterior, anterolateral or posterior spinal systems.
The DISCOVERY Facet Screw Fixation System is intended to stabilize the spine as an aid to fusion by two different fixation methods:
Transfacet fixation: The screws are inserted bilaterally through the superior side of the facet, across the facet joint and into the inferior pedicle.
Translaminar Facet fixation: The screws are inserted bilaterally through the lateral aspect of the spinous process, through the lamina, through the superior side of the facet across the facet joint and into the inferior pedicle.
For both methods this system is indicated for the posterior surgical treatment of any or all of the following at the L1 to S1 (inclusive) spinal levels:
1) Trauma, including spinal fractures and/or dislocations;
2) Spondylolisthesis;
3) Spondylolysis;
4) Pseudoarthrosis or failed previous fusions which are symptomatic, or which may cause secondary instability or deformity;
5) Degenerative diseases which include:
(a) degenerative disc disease (ddd) as defined by back pain of discogenic origin as confirmed by patient history with degeneration of the disc as confirmed by radiographic studies and/or
(b) degenerative disease of the facets with instability.
The EXPEDIUM Anterior Spine System is intended for anterolateral screw fixation of the T4 to L4 levels of the spine, with metal at least 1 cm from a major vessel. The EXPEDIUM Anterior Spine System may be used in either thoracoscopic procedures or open procedures.
The EXPEDIUM Anterior Spine System is indicated for:
• degenerative disc disease (ddd) defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies;
• spondylolisthesis;
• trauma (i.e., fracture or dislocation);
• spinal stenosis;
• deformities or curvatures (i.e., scoliosis, kyphosis, and/or lordosis);
• tumor;
• pseudarthrosis; and previous failed fusion.
The FRONTIER Anterior Scoliosis System is intended for anterolateral screw fixation to the T4 to L4 levels of the spine, with metal at least 1cm from a major vessel. The FRONTIER Anterior Scoliosis System may be used in either thoracoscopic procedures or open procedures.
The FRONTIER Anterior Scoliosis System is indicated for:
• degenerative disc disease (ddd) defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies;
• spondylolisthesis;
• trauma (i.e., fracture or dislocation);
• spinal stenosis;
• deformities or curvatures (i.e., scoliosis, kyphosis, and/or lordosis);
• tumor;
• pseudarthrosis; and previous failed fusion.
The KANEDA Anterior Scoliosis System is intended for anterolateral screw fixation to the T4 to L4 levels of the spine.
The KANEDA Anterior Scoliosis System is indicated for:
• degenerative disc disease (ddd) defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies;
• spondylolisthesis;
• trauma (i.e., fracture or dislocation);
• spinal stenosis;
• deformities or curvatures (i.e., scoliosis, kyphosis, and/or lordosis);
• tumor;
• pseudarthrosis; and previous failed fusion.
The KANEDA SR Anterior Spinal System is intended for anterolateral screw fixation to the T10 to L3 levels of the spine. Specific indications are degenerative disc disease (defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies), deformities (scoliosis, kyphosis, lordosis), tumor, fracture and revision of previous surgery.
The intended levels for treatment with the M-2 Anterior Plate System are from T3 to L3. In order to treat levels from T3 to L3, plate attachment is from T2 to L4. The M-2 Anterior Plate System is intended to treat one motion segment per construct.
The M-2 Anterior Plate System is indicated for:
• degenerative disc disease (ddd) defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies;
• spondylolisthesis;
• trauma (i.e., fracture or dislocation);
• spinal stenosis;
• deformities or curvatures (i.e., scoliosis, kyphosis, and/or lordosis);
• tumor;
• pseudarthrosis; and previous failed fusion.
The MOUNTAINEER Laminoplasty System is intended for use in the lower cervical and upper thoracic spine (C3 to T3) in laminoplasty procedures. The MOUNTAINEER Laminoplasty System is used to hold or buttress the allograft or autograft material in place in order to prevent the allograft or autograft material from expulsion or impinging the spinal cord.
The intended levels for treatment with the PROFILE Anterior Thoracolumbar Plate System are from T1-L5 spine instability as a result of fracture (including dislocation and subluxation), tumor, degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), scoliosis, kyphosis, lordosis, spinal stenosis, or a failed previous spine surgery.
The UNIVERSITY PLATE Anterior System is intended for lateral screw fixation to the T9-L4 levels of the spine, and is not suitable for the attachment to the sacrum. Specific indications are fracture, tumor, previous failed fusion and pseudarthrosis, and degenerative disc disease (defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies).
The VIPER F2 Facet Fixation System is intended to stabilize the spine as an aid to fusion by the transfacet fixation method only:
Transfacet fixation: The screws are inserted bilaterally through the superior side of the facet, across the facet joint and into the inferior pedicle.
This system is indicated for the posterior surgical treatment of any or all of the following at the L1 to S1 (inclusive) spinal levels:
1) Trauma, including spinal fractures and/or dislocations;
2) Spondylolisthesis;
3) Spondylolysis;
4) Pseudoarthrosis or failed previous fusions which are symptomatic, or which may cause secondary instability or deformity;
5) Degenerative diseases which include:
(a) degenerative disc disease (ddd) as defined by back pain of discogenic origin as confirmed by patient history with degeneration of the disc as confirmed by radiographic studies and/or
(b) degenerative disease of the facets with instability.
