PurposeCervical total disc arthroplasty (TDA) is a motion-preserving alternative to anterior cervical discectomy and fusion that has gained popularity among spine surgeons. Although generally effective, TDA has been associated with rare cases of progressive osteolysis, a complication whose natural history and impact on clinical outcomes are not well understood. This case report aims to present a case of progressive osteolysis following cervical TDA with the SpinalKinetics® M6-C Artificial Cervical Disc and to discuss the clinical approach and implications for patient management.MethodsWe reviewed the clinical course of a patient who underwent cervical TDA with the SpinalKinetics® M6-C Artificial Cervical Disc and subsequently developed progressive osteolysis. The patient's symptoms, diagnostic findings, and treatment progression were documented, with a focus on the timing of symptom onset, imaging, and the therapeutic interventions applied.ResultsThe patient demonstrated a delayed onset of symptoms related to osteolysis, which was identified through CT imaging as a progressive complication. The slow progression of osteolysis in this case underscores the need for careful monitoring, as early symptoms may be subtle but can lead to significant clinical implications if unaddressed.ConclusionThis case highlights the potential for progressive osteolysis as a complication following cervical TDA, emphasizing the importance of ongoing surveillance and increased awareness among spine surgeons. Early identification and monitoring of osteolysis may mitigate the risk of severe outcomes and guide timely intervention.© 2024. The Author(s).
