Adult spinal deformity surgery is a complex procedure that involves many risks and complications. Bone grafts and bone substitutes are essential to achieve fusion and manage stability in spinal surgery. Autologous bone has been considered the "gold-standard" for obtaining a spinal fusion. However, the source from which to obtain it is limited. Furthermore, the problems of bone quality in patients with osteoporosis and the morbidity have forced the orthopedic community to seek other options. I-Factor ™ Bone Graft (Cerapedics, Inc., Westminster, CO) is a compound formed by peptide P-15 bound to an anorganic bone mineral of bovine origin that is composed of porous and smooth hydroxyapatite (ABM) particles. In the literature there are no articles which identify bone formation with the i-Factor ™ graft in more than 4 instrumented levels, therefore the development of this study will allow assessing the fusion rate and quality of life of patients, which could lead to an improvement in the management and decision-making of surgical procedures, as well as better control of healthcare spending

In the i-Factor ™ group it will be placed longitudinally in the intertransverse area. Likewise, in both groups, only autologous and bench bone will be placed in the intersomatic cages. The vertebrae where the i-Factor ™ is placed will be noted on the data collection sheet.

Fusion rate
The success of the fusion at 12 and 24 months will be determined by a specialized radiologist by the evidence in the CT scan of trabecular bone bridges between the inter-transverse areas of the vertebral bodies and the absence of radiolucency adjacent to the implants.
