Adult patients affected by degenerative disc disease, meeting all inclusion/exclusion criteria, will be proposed to take part to the current post-marketing surveillance study during their pre-operative visit. They will be provided with an information letter and, in case of acceptance to participate to the study, asked to sign a consent form.~After enrolment, each patient will be monitored for 13 months. Data concerning demography, preoperative clinical conditions, surgical details including device implanted and complications occurred, postoperative clinical and/or radiological assessments (as per standard routine at 5 weeks, 3, 7 and 13 months) will be prospectively collected. The level of bone fusion will be evaluated with a postoperative CT scan at 7 ±2 months follow-up
The use of patient specific guides with proper preoperative planning, following a cortical bone trajectory technique, should guarantee a successful surgery and benefit of less invasive technique.~This study intends to measure the safety and efficacity of MySpine MC patient-specific guide system, when used according to its general indication of use and following the surgical technique suggested by the manufacturer
