Orthopedic Spinal Fixation Vertebral Hook Medical Instrument

Introduction:

The intervertebral fusion cage is a large, hollow cylinder made of titanium. It is designed as a "cage" so that bone graft can be placed inside the hollow cylinder to allow a spinal fusion to occur between two vertebrae. The holes that are throughout the cage allow bone to form around and through the cage connecting the two vertebrae with solid bone.

The intervertebral fusion cage is designed to spread two vertebrae apart, allowing several critical functions. The openings where the nerve roots leave the spine become larger, decreasing pinching and irritation. It also decreases segmental instability and mechanical pain in the spine by replacing the disc and holding the vertebrae in the correct position until fusion occurs.

Additionally, the 5.5/6.0 screw-rod system for spinal internal fixation offers a mature implant system with choices of sterile or non-sterile packaging.

Indications for serious spinal instability:

• Degenerative spondylolisthesis: A disorder causing forward motion or slip of one vertebral body over another.
• Spinal fracture: Breaks in the bones of the spine.
• Scoliosis: Curvature of the spine.
• Kyphosis: A progressive spinal disorder also known as humpback.
• Spinal tumor: Growth on the spine.
