PEEK Intervertebral fusion cage is a Spinal Implant used for lumbar fusion, aimed at providing a bony connection to treat stubborn back pain caused by lumbar disc disease or spinal instability.
Lumbar spondylolisthesis is a common type of lumbar disease, and its treatment requires the use of intervertebral fusion devices. The selected materials are also particularly important. PEEK (polyether ether ketone), as a new type of biocompatible material, is characterized by extremely high biocompatibility, excellent mechanical properties, and good chemical stability. This has led to the widespread application of PEEK materials in the medical field, especially in the manufacturing of intervertebral fusion devices.
Why is PEEK material very suitable for manufacturing intervertebral fusion orthopedic implant? This is closely related to its performance advantages.
1. Excellent biocompatibility, PEEK material has excellent biocompatibility, which can avoid foreign body reactions and reduce the occurrence of postoperative complications.
2. Excellent mechanical performance, PEEK material has extremely high strength and stiffness, which can ensure the stability of the intervertebral fusion cage after implantation, and can also withstand the load of the human body.
3. Good chemical stability, PEEK material is not easily decomposed by organisms, which can ensure the long-term stability of implants.
4. Easy to manufacture, PEEK material is easy to process and manufacture, and can be used to manufacture intervertebral fusion cages that meet personalized needs of patients.
Compared with titanium alloy, intervertebral fusion cages made of PEEK material have more advantages. PEEK material is perfectly compatible with X-ray photography and nuclear magnetic resonance imaging, and its elastic modulus is relatively low. In order to further improve the performance of PEEK materials, scientists have adopted modification methods. By utilizing type I collagen for adsorption crosslinking, the hydrophilicity and cell adhesion and proliferation of PEEK materials can be enhanced. The modified material has better biocompatibility and bone fusion ability compared to unmodified materials, providing spine fracture surgery patients with safer and more effective treatment options.
