We will investigate if the use of Inductos in a intervertebral cage will provide us with better and or faster fusion rates.

Exclusion criteria
Exclusion criteria: Pregnant at time of surgery or plans to become pregnant within 2 years following surgery. Number of levels to be fused are greater than 3. Subject has a lumbar spine deformity, i.e. scoliosis, kyphosis, flat back, ankylosing spondylitis Will not be available or will not make self available for follow-up visits in accordance with the protocol to at least 24 months. Currently implanted with a posterior instrumentation system. Mentally incompetent or prisoner. Subject is being treated with investigational devices for the same disorder. Active localized or systemic infection. Past spinal infection.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: Is there a faster and higher fusion ratio in a group of patients in which the intervetebral cage is filled with Inductos in comparison with patients where the cage is filled up with autologous bone graft.;Secondary Objective: ;Primary end point(s): Two years after surgery, through clinical, anamnestic and radiological investigation | — |
