PEEK spinal cages, also known as interbody fusion cages, are used in Spinal Implant surgery to replace damaged discs and provide an ideal environment for two-vertebral fusion.
PLIF PEEK cage is suitable for orthopedic lumbar and lumbosacral segmental fusion,mainly including degenerative disc disease and spinal instability,degenerative/isthmic spondylolisthesis,revision spinal fracture surgical after simple discectomy, pseudarthrosis formation or spinal fusion failure. PLIF PEEK cage is not recommended to be used alone, but should be used in conjunction with screen-rod system.
The indications of TLIF cage are orthopaedic spinal degenerative diseases and spinal instability, revision after discectomy, pseudarthrosis or failed fusion surgery, degenerative spondylolisthesis and isthmic spondylolisthesis.
Features and Advantages
1. A variety of heights are available (5-8mm).
2. More precise placement,the PEEK material is X-ray penetrable, and the metal bone pin is inserted both front and back, allowing the doctor to better determine the placement of the implant.
3. More stable after operation,the barbed tooth shape can provide good stability and avoid backward movement of the implant,which will affect the surgical effect.
4. Solid cage fusion can eliminate motion,increase nerve root space,stabilize the spine,restore spinal alignment and relieve pain.
5. For the bone graft window,sufficient amount of bone graft material was filled through the PEEK spinal cage to promote bone fusion.
The PEEK interbody cage is placed between the two vertebrae to be fused.The peek orthopedic implant is composed of the main body of the cage and part of the titanium alloy wire as the development point.The accuracy of the position of the cage after implantation is visualized by X-ray film after operation.
What is PILF?
PLIF (posterior lumbar interbody fusion) is a surgical technique for fusing lumbar vertebrae by removing the intervertebral disc and replacing it with a (titanium) cage.The vertebrae are then stabilizedby an internal fixator(transpedicular instrumented dorsal WK fusion). PLIF is a stiffening operation on the spine.
In contrast to the ALIF (anterior lumbar intervertebral fusion),this operation is performed from the posterior,i.e. from the back.A surgical variant of the PLIF is the TLIF ("transforaminal lumbar interbody fusion").
What is TILF?
TLIF is a unilateral approach for interbody fusion to restore normal intervertebral space height and lumbar spine physiological lordosis. It is characterized by a posterior approach,which enters the spinal canal from one side.To achieve bilateral vertebral body fusion,there is no need to interfere with the central canal,which reduces the occurrence of cerebrospinal fluid leakage, does not need to stretch the nerveroot and dural sac too much,and reduces the probability of nerve damage.The contralateral lamina and facet joints are preserved,the bone graft area is increased,360°fusion is feasible,the supraspinous and interspinous ligaments are preserved,which canreconstruct the posterior tension band structure of the lumbar spine.
