Text

Objective: To evaluate the influence of demineralized bone matrix (DBM) on long-term results after anterior cervical discectomy and fusion (ACDF) with stand-alone PEEK cages.

Method: A retrospective age-, gender-, symptoms- and level-matched pair analysis was performed on 45 pairs of patients who underwent anterior cervical discectomy and fusion (ACDF) with stand-alone PEEK cages with a minimum follow-up of 12 months. In the study group, DBM was used as an osteogenic filling substance. Radiographic follow-up included static and flexion/extension radiographs. Changes in the operated segments were measured and compared to radiographs directly after surgery. Clinical outcome was evaluated by a physical exam and the EuroQOL questionnaire (EQ-5D).

Results: Fusion rate in the study group was 83% and 86% the control group. Subsidence rate in the study group was 33% and 22% in the control group. Cervical alignment improved in 2% and 11%, worsened in 20% and 11% and remained same in 71% and 78% in the study and control group, respectively. VAS Overall Health increased from 46 ± 23 to 74 ± 21 in the study group and from 37 ± 22 to 73 ± 23 in the control group.

Conclusions: Application of DBM for ACDF with stand-alone PEEK cages has no significant influence on radiological or clinical outcome.
