start of 1:1-Block public summary

Brief Summary in Lay Language

Spondylolisthesis is a subluxation of one vertebral body on another due to long-standing intersegmental instability.
It leads to nerv root compression within confines of spinal canal.
The nerval compression may cause nerval damage and loss of function including neurological deficit of hip, legs, bladder and rectum. The spondylolisthesis may finally lead to vertebral disc herniation, spondylathrosis and low back pain.
Patients who present with sensory changes, muscle weakness, or cauda equina syndrome, are more likely to develop progressive functional decline without surgery.
The goal of surgical intervention is decompression of the neural structures to relieve pain and other neurologic symptoms.
The clinical standard is surgical decompression as well as surgical decompression followed by fusion. Both methods reveal relief of symptoms. To this day there is no evidence which procedure provides the better long term outcome.

Brief Summary in Scientific Language

The objective of this study is to compare the clinical outcome of two standard surgical procedures for the treatment of degenrative spondylolisthesis. The surgical procedures are surgical decompression and surgical decompression followed by fusion.
The primary objective is the result of Oswestry Disability Index (ODI) at 12 months after surgery.
Secondary objetives are the evaluation of pain by Visual analogue scale (VAS) prior to and one week, 3, 6,9, months after surgery.
Additionally posoperative complications and the correllation between clinical outcome and radiological findings will be invastigated.
