PS, MIS-Tower Reduction, Cannulated Dual Lead 8.5X50mm. The FOCUS Pedicle Screw System is intended for use in the non-cervical posterior spine (T1-S1) 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: degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies), spondylolisthesis, fracture, dislocation, deformities or curvatures (i.e., scoliosis, kyphosis, and/or lordosis), spinal stenosis, tumor, pseudarthrosis, and failed previous fusion.
A small, threaded, implantable rod with a screw head and drive intended for internal spinal fixation by being screwed into the spine to hold a correction/stabilization device (e.g., rod, plate, tether) to bone; it is made of a material that is not chemically degraded or absorbed via natural body processes (e.g., surgical steel, titanium alloy, carbon fibre). It is available in various types (e.g., pedicle or transfacet, with a slotted, cross, star, or polygonal drive), and is typically used to provide immobilization and stabilization of spinal segments in the treatment of spinal instabilities or deformities. A screw head adaptor intended to stabilize a rod may be included with the screw.
