Abstract

CASE: We report a case of implant failure after primary 2-level M6-cervical disc replacement (M6-C; Spinal Kinetics) at C4-5 and C5-6. At revision surgery, a full-thickness tear was identified in the sheath of the C5-6 implant. Histology from periprosthetic tissue demonstrated polyethylene particles without acute inflammation. Tissue cultures were positive for Propionibacterium acnes, but ultrasonicate cultures were negative for both prostheses. An independent laboratory test confirmed mechanical failure of the C5-6 prosthesis. CONCLUSION: This is the first report of mechanical failure associated with wear-debris osteolysis after M6-C disc arthroplasty. Therefore, continued surveillance after CTDR is necessary.
