Scope of Application

Indicated for skeletally mature patients with grade 1 or 2 lumbar spinal stenosis (L1-L5) accompanied by low back pain and at least moderate functional impairment, requiring surgical decompression.

Product Features

★ Four sheet-like fixation devices with serrated projections: control rotation, maintain spinal alignment, and prevent kyphosis.

★ Serrated projections on the U-shaped groove: increase contact area and reduce kyphosis.

★ U-shaped groove: maintains interspinous and intervertebral disc distraction; cushions axial stress.

★ Circular holes on the four sheet-like fixation devices: facilitate ligament suture.

Product Advantages

• U-shaped main body design – It provides a large surface area, which minimizes the stress on the spinous processes to a great extent; meanwhile, it is compatible with the human physiological anatomy.

• The U-shaped main body and the serrated structure on the inner side of the flanges deliver excellent fixation performance.

• The staggered arrangement of the upper and lower flanges meets the requirement for simultaneous implantation at two adjacent spinal segments and prevents flange overlap.

• The circular holes on the flanges allow for ligament suturing or screw implantation to enhance stability.
