Intended Use
The MOSS Miami Spinal System is intended for non-cervical use in the spine. When used with anterior screw fixation or posterior hook, non-pedicle screw fixation the MOSS Miami Spinal System is intended to treat scoliosis, kyphosis and lordosis, fracture, loss of stability due to tumor, spinal stenosis, spondylolisthesis, a previously failed back surgery or degenerative disc disease (i.e. discogenic back pain with degeneration of the disc confirmed by history and radiographic studies). When used with pedicle screw fixation, the MOSS Miami Spinal System is intended for use in patients with severe spondylolisthesis (Grades 3 and 4) at the L5-S1 vertebral joint, having fusions with autogenous bone graft, with the device fixed or attached to the lumbar and sacral spine (levels of pedicle screw attachment are L3 and below), and for whom the device system is intended to be removed after the development of a solid fusion mass.
Device Story
Spinal instrumentation system consisting of rods, monoaxial/polyaxial screws, hooks, and connectors; used for non-cervical spinal stabilization and fusion. System components available in stainless steel or titanium. Device implanted by surgeons during spinal procedures to provide mechanical stability while bone graft achieves fusion. Titanium screws (5mm and 8mm) added to existing system; intended for use with previously cleared MOSS Miami components. Provides structural support to spinal column; facilitates fusion in patients with degenerative or traumatic spinal conditions.
Clinical Evidence
No clinical data provided; substantial equivalence based on design and material comparison to predicate devices.
Technological Characteristics
Spinal fixation system components including longitudinal rods, monoaxial/polyaxial screws, hooks, transverse/axial connectors, and washers. Materials: Stainless steel or titanium. Dimensions: 4-5mm rods (SS), 5.5mm rods (Ti); 5-8mm screw diameters. Mechanical fixation principle. Sterilization not specified.
Indications for Use
Indicated for patients requiring non-cervical spinal fixation for scoliosis, kyphosis, lordosis, fracture, tumor-related instability, spinal stenosis, spondylolisthesis, failed back surgery, or degenerative disc disease. Pedicle screw fixation is indicated specifically for severe spondylolisthesis (Grades 3-4) at L5-S1, requiring autogenous bone graft and subsequent device removal after fusion.
Regulatory Classification
Identification
A spinal interlaminal fixation orthosis is a device intended to be implanted made of an alloy, such as stainless steel, that consists of various hooks and a posteriorly placed compression or distraction rod. The device is implanted, usually across three adjacent vertebrae, to straighten and immobilize the spine to allow bone grafts to unite and fuse the vertebrae together. The device is used primarily in the treatment of scoliosis (a lateral curvature of the spine), but it also may be used in the treatment of fracture or dislocation of the spine, grades 3 and 4 of spondylolisthesis (a dislocation of the spinal column), and lower back syndrome.
