Identification of clinical and instrumental parameters that could predict the outcome of surgical decompression of lumbar degenerative stenosis.
Degenerative lumbar spine is the most common cause of chronic pain and disability with remarkable economic impact. Treatment begins with conservative options (physical combined with antalgic therapy) but often requires surgical treatment.
Two different groups of patients affected by symptomatic lumbar stenosis with no preoperative radiological signs of instability will be recruited in a prospective trial and proposed for surgery: microsurgical decompression (MiD) or decompression and instrumented fusion (MiD + F). Clinical and mechanical outcomes of two different treatments (MiD vs. MiD+F) will be compared.
An in-vitro biomechanical study will evaluate the biomechanical effect of the two surgical techniques.
The aim of this project is to obtain robust data for tailoring the surgical approach to patient individual characteristics and needs, to gain the best clinical evidence, and possibly reducing the overall costs of management of this disease.

| Short Form 12 | The Short Form-12 (SF-12) healthy questionnaire is a generic standardized instrument assessing the impact of health on quality of life. It is made of twelve questions from which are calculated two different score: a Physical Component Score (with a score range 23,99 - 56,57) and a Mental Component Score (with a score range 19,06 - 60,75). The higher the number the better the outcome. | at baseline (day 0) |
