[The trend towards full-endoscopic decompression : Current possibilities and limitations in disc herniation and...

The most frequent causes of degenerative constrictions of the spinal canal are disk herniations and spinal stenoses. The lumbar and cervical spine is the most affected.

After conservative treatments have been exhausted, surgical intervention may be necessary. Today, microsurgical decompression is regarded as the standard procedure in the lumbar region, while in the cervical spine, microsurgical anterior decompression and fusion are standard. Full-endoscopic techniques for decompression are becoming increasingly widespread worldwide. The development of various surgically created approaches and appropriate instrument sets have made the full-endoscopic operation of disk herniations and spinal stenosis possible. This development has also permitted resection of soft disk herniations in the cervical spine. The use of the approaches depends on anatomical and pathological inclusion and exclusion criteria.

The clinical results of standard procedures have been achieved, which must be regarded as a minimum criterion for the introduction of new technologies. On the basis of EBM criteria, it can be established that using the full-endoscopic techniques developed, adequate decompression is achieved in the defined indications with reduced traumatization, improved visibility conditions, and positive cost benefits. Today, full-endoscopic operations may be regarded as an expansion and alternative within the overall concept of spinal surgery.
