Developed in collaboration with surgeons, the Sequoia Pedicle Screw System sets a new standard with intuitive features that simplify spine surgical flow, speed implantation, minimize head splay and provide surgeon comfort.
The Zimmer Spine Sequoia Pedicle Screw System is designed to aid in the surgical correction of several types of spinal conditions. This system is intended only to provide stabilization during the development of a solid fusion with a bone graft. These implants are intended to be removed after the development of a solid fusion mass.
The Sequoia Pedicle Screw System consisting of open style polyaxial screws, titanium rods (varying lengths) and connectors is intended to provide temporary stabilization following surgery to fuse the spine. The polyaxial screw design allows the surgeon to use a top-loading technique for dropping the spinal rod down to the fixation components into a u-shaped opening.
This system offers a single package containing a wide array of implant styles, allowing the surgeon maximum flexibility to address patient needs.
SpeedLink II™ Transverse Connectors are provided to increase rotational stiffness to the final construct.
When intended for pedicle screw fixation from T1-S1, the Sequoia Pedicle Screw System is intended to provide immobilization and stabilization of spinal segments in skeletally mature patients as an adjunct to fusion in the treatment of the following acute and chronic instabilities or deformities of the thoracic, lumbar, and sacral spine: degenerative disc disease (defined as discogenic back pain with degeneration of the disc confirmed by history and radiographic studies), degenerative spondylolisthesis with objective evidence of neurologic impairment, fracture, dislocation, deformities, or curvatures (i.e. scoliosis, kyphosis, and/or lordosis), tumor, and failed previous fusion. As a pedicle screw system placed between L3 and S1, the indications include Grade 3 or Grade 4 spondylolisthesis, when utilizing autologous bone graft, when affixed to the posterior lumbosacral spine, and intended to be removed after solid fusion is established. When intended for non-pedicle, posterior screw fixation of the non-cervical spine (T1- S1), the indications are idiopathic scoliosis, neuromuscular scoliosis/kyphoscoliosis with associated paralysis or spasticity, scoliosis with deficient posterior elements such as that resulting from laminectomy or myelomeningocele, spinal fractures (acute reduction or late deformity), degenerative disc disease (back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), tumor, spondylolisthesis, spinal stenosis, and failed previous fusion. When intended for anterolateral screw, rod, and/or cable fixation of the T6-L5 spine, the indications are degenerative disc disease (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, and failed previous fusion.
Following are specific warnings, precautions, and adverse effects that should be understood by the surgeon and explained to the patient. These warnings do not include all adverse effects that can occur with surgery in general, but are important considerations particular to metallic internal fixation devices. General surgical risks should be explained to the patient prior to surgery.
