The patient came to the clinic 12-January-2010 complaining of low back pain for 6 years with bilateral sciatica more the right . The last 3 months progressed right sciatica  down to L5 territory, making her unable to walk more than 50 meters. She had exaggerated scoliotic stance with SLRS 5 degrees in the right. There was weak dorsiflexion 3/5 of the right foot.

MRI performed 12-December-2009 showing extruded disc L4-5 huge central more to the right.

Using the image-intensifier the L4-5 level was identified and right hemiflavotomy L4-5 with foraminotomy of right L5 root was performed. The extruded disc was removed lateral to the axilla and right sided cleaning of L4-5 was done from the right.

Using PEEK Satellite spinal system, it was necessary to use sphere No 15 to have acceptable prerequisites and check image-intensifier showed central location of the device.  The curette was not used intentionally, so as not to harm the endplate. Contrast was injected inside the disc space from the right. It was noted that the contrast media could not cross the right half to the left.

Routine closure of the wound.

Smooth postoperative recovery, with improvement of the power the right foot.

The surgeon think that he performed meticulous cleaning of the disc space. The use of contrast in this case was an illustration, that the disc remnants still there. Even the contrast could not fill the gap contra-lateral the excision and cleaning. This means, that there is still layers of the disc material behind the sphere.

The diameter of the sphere is an indicator to the possible postoperative estimated recurrence . The more the diameter is parallel with the higher recurrence , in case of not using the sphere.
