In this study, following a screening period of a maximum of 30 days, 30 patients will undergo a two-level instrumented posterolateral fusion (PLF) procedure. Prior to surgery, each patient will be randomized to receive MagnetOs Putty on the assigned side of the spine and autograft bone on the other at the diseased levels. They will be followed up at discharge, Week 2, Week 6, Month 3, Month 6, Month 9, and Month 12. An interim analysis will be performed once 15 patients have completed their Month 6 visit and have measurements for the endpoints available to measure effectiveness. The primary endpoint will be analyzed at Month 12. In this study, MagnetOs Putty will be applied according to the latest Instructions for Use approved in the United States. Specifically, MagnetOs Putty will be used as a bone graft extender mixed with autograft in a 1:1 vol.% in patients with two-level degenerative disc disease with up to grade 1 spondylolisthesis requiring treatment with an instrumented posterolateral spine fusion procedure. The fusion procedure (PLF) will be left to the surgeon's discretion. Radiographs will be obtained at Screening, Day 0, Week 6, Month 3, and Month 9. CT scans will only be obtained at Month 6 and Month 12.
