Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this trial is to evaluate if P-15L bone graft (investigational device) is not inferior in effectiveness and safety to local autologous bone (and allograft where necessary) as an extender (control device) when applied in instrumented transforaminal lumbar interbody fusion (TLIF) in subjects with degenerative disc disease (DDD). In addition to the general overall objective, a sub-group analysis will be performed on the high-risk subject population (tobacco use, obesity, diabetes), as previous studies have shown negative effects of smoking, obesity and diabetes on fusion and bone healing, increased peri/postoperative complications, and lower patient-reported outcome scores.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

Skeletally mature adults between 22 and 80 years old (inclusive);

Back pain with radicular symptoms as evidenced by leg pain, confirmed by history and physical exam;

Oswestry Low Back Pain Disability Questionnaire score of ≥ 35;
