Brief Summary

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

Outcome Measures

Primary Outcomes (6)

  • 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.

    2 years

  • Minimal Clinically Important Difference (MCID)

    Minimal clinically important difference is defined a smallest clinical change that is important to the patient.

  • Short Form Health Survey-12 General Quality of life questionnaire

    The questions that follow ask what you think about your health. Your answers will allow you to know how you are and to what extent you are able to do your usual activities. Patients improve when the puntuation is more than 50.

Control

NO INTERVENTION

Control group: autologous bone + bench bone

i-Factor

EXPERIMENTAL

I-Factor group: autologous bone + bench bone + i-Factor™ bone graft

Biological: i-FactorTM Bone graft

Interventions

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.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients of legal age.
  • Patients diagnosed with adult deformity, whether due to scoliosis, imbalance, thoracolumbar curves, etc. In which the minimum number of levels to be instrumented is 5, that is, 4 intervertebral discs.
  • Patients who provide their informed consent in writing. (In the event that the patient's circumstances do not allow him to grant consent, this may be provided by the legal representative).
  • Present radiological tests, computed tomography and / or magnetic resonance imaging prior to surgery.
  • The implants used in the surgery are Cobalt Chrome bars and Titanium screws and interbody cages.

You may not qualify if:

  • Patients who are expected to be unavailable for follow-up.
  • Patients with mental disabilities that make it difficult for them to fill in the questionnaires.
  • Patients who have had other types of implants placed, other than Cobalt Chrome bars and Titanium screws and interbody cages.
  • Patients who are going to have cemented and / or expansive screws, Peek boxes or another type of material other than Titanium.
  • Underlying neurological or neuromuscular disease.
  • Underlying inflammatory or tumor disease.
