Case 1: Instability of the lower cervical spine that resulted in narrowing of the spinal canal.
Decompression of the spinal canal was performed via an anterior approach together with instrumentation by plate and screws.

Case 2: Patient who suffered from wearing down (degenerative disc disease) of the segment L5/S1.
Dynamic stabilization was provided by an artificial disc implanted by an anterior approach.

Case 3: Example of an adjacent instability after fusion of the upper lumbar spine that was treated with dynamic implants (artificial disc).

Case 4: Disc degeneration of two levels in the cervical spine that was treated by dynamic implants via an anterior approach.
