Pseudoclaudication causes complaints which originate from compression of neural structures of the narrow lumbar spinal canal due to degenerative changes with osteoarthrotic thickening and osteophytosis of the facet joints and the hypertrophied yellow ligament. Frequently bulging discs or a segmental loss of stability increase the compression. The diagnosis is made clinically because although CT or MRI enable a confirmation of the diagnosis, they do not, however, allow an adequate correlation of the derived results with the clinical findings. The complaints worsen under exertion with symptoms in the legs and back pain or a combination of both as well. A surgical procedure should be considered when conservative treatment fails, the VAS score usually exceeds 4 points, and the limitation of the walking capability falls below 500 m. If there is a permanent neurological deficit, an early decision can be appropriate and there is an absolute and urgent indication in signs of a cauda equina lesion. The objective postoperative results of open decompressive surgery are encouraging and associated with low complication rates. The subjective satisfaction of the patients is even better. Even eldery patients profit from an increasing mobility accompanied by the chance to retain self-sufficiency.
