Abstract
Therapy for spinal stenosis remains difficult. The possibilities for conservative management are limited and not satisfactory in the more severe cases. Various surgical procedures are possible, such as decompression, decompression and fusion without instrumentation and decompression and fusion with instrumentation. The aim of our meta-analysis was to compare the postoperative results of these three surgical techniques in the literature and, thus, to establish a treatment of choice for degenerative lumbar spinal stenosis. Via Medline, 30 articles met the inclusion criteria for our study, leading to a total number of 1668 cases being included in the meta-analysis. The evaluation was made according to our own definition of outcomes, based on criteria most commonly used in the studies reviewed. We found that in patients suffering degenerative spinal stenosis for up to 8 years, decompression without fusion showed the best results. For a duration of symptoms of 15 years or more, decompression with instrumented fusion had the best results. Analysing all postoperative outcomes, decompression is the surgical procedure with the highest rate of success and the fewest complications, followed by decompression with instrumented fusion. In surgery for degenerative lumbar spinal stenosis, decompression and fusion without instrumentation was the least successful procedure. As patients suffering from a degenerative spinal stenosis often are elderly, operations are risky and place a strain on them. This review of the literature shows that the least invasive surgical procedure can obtain the best results if the correct diagnosis is made and if the operation is carried out within the first years of the disease.
