The implant is inserted unilaterally between the vertebral bodies through a transforminal approach with far lateral access to the neural foramina without neural manipulation.
Distraction across the disc space and compression of the cage (on release of distraction) calls for the immediate achievement of biomechanical stability followed by long-term stability from solid bony fusion.
The anterior position of the Bean Cage offers a solid bilateral support of the anterior column, providing fusion path by filling both the implant and the anterior space with cancellous bone.
Indications
Advantages
Mechanical instability
Low grade spondylolisthesis
Spinal stenosis
Degenerative disc disease
Lumbar Inter Body Fusion
Bean-like form ensures a maximized contact area between vertebrae and implant
Slim enough to be inserted through the foramen
Optimal postoperative control
Curved design for bilateral support and easy insertion
Has a lordosis angle of 4 °
Primary stability is achieved through the toothed surfaces
In combination with a posterior fixation device immediate stability of the motion segment is ensured
Unilateral steep approach for preservation of the contra lateral joint
