Lumbar fusion is frequently used for a variety of degenerative, traumatic, and oncologic conditions of the lumbar spine. Advancements in surgical techniques, including spinal instrumentation and combined anterior and posterior procedures have led to increased rates of fusion. Autologous iliac crest bone graft (ICBG) is the gold standard bone graft and offers osteoconductive, osteoinductive and osteogenic properties that aid in achieving successful fusion. However, harvesting ICBG may result in donor site infection, hematomas, increased operative time, prolonged pain, altered cosmesis, and in rare instances arterial and nerve injury [Cellular bone allografts (CBAs) provide an innovative addition to allograft technologies and are an alternative to other bone grafting options. From a structural standpoint, allograft may serve in the absence of revascularization and creeping substitution processes. Cellular bone allografts provide the same three osteometric properties promoted with ICBG without the complications of donor site morbidity associated with bone graft harvesting, which has been reported to be as high as 38% [A prospective, post marketing, multicenter, open label, non-randomized clinical study was conducted to assess the efficacy and safety of CBA (Trinity Elite
