Primary Outcome Measures :
  1. Complication rate [ Time Frame: intraoperative ]
    Registration of intraoperative complications during surgery

Secondary Outcome Measures :
  1. Oswestry Disability Index [ Time Frame: in 5 days from surgery - 6 months follow-up ]
    Evaluation of clinical outcomes using Oswestry Disability Index (ODI) questionnaire. It is a scaled questionnaire from 0 to 100 in which the higher the value, the worst the outcome.

  2. Length of surgery [ Time Frame: intraoperative ]
    Evaluation of length of surgery

  3. Subsidence rate [ Time Frame: in 5 days from surgery ]
    Evaluation of subsidence rate at postoperative x-ray

  4. Visual Analogic Score (VAS) leg and back [ Time Frame: in 5 days from surgery - 6 months follow-up ]
    Evaluation of clinical outcomes using the VAS score, going from 0 to 10, where 0 means no pain and 10 the worst pain possible.
