When to use TESSYS® and when to use iLESSYS®?
Transforaminal access to the spinal canal is the preferred method for experienced TESSYS® users for pathologies in the ventral and lateral spinal canal, as well as, inside and outside of the foramen. In certain cases, the interlaminar access can be more gentle. For example, with cases at levels L4/5 and L5/S1, the interlaminar window is rather big, and therefore, little or no stabilizing structures need to be removed. For herniated discs in the dorsal and dorsal-lateral spinal canal, the surgical sectioning of the ligamentum flavum by about 0.8 cm is sufficient.
The 360° decompression of the spinal canal: 2 types of access – 1 goal
With both, transforaminal and interlaminar endoscopic access, the user now has a 360 degree range of access to the spinal canal.
In addition to herniated discs, narrowing of the spinal canal and the exiting nerves due to degenerative processes and cysts of the facet joints is also an indication. These degenerative conditions are becoming a central challenge in medicine as the structure of the population is changing and life expectancy is continuously rising. Literature refers to an incidence rate between 1.7 and 10%.
With this endoscopic access, the point of decompression can be exactly determined and the surgical access planned accurately, using comprehensive clinical and imaging diagnostics such as X-ray, CT scans and myelography.
