Summary
Progressive osteolysis can occur after cervical total disc arthroplasty (TDA). Careful monitoring is crucial for early detection and management of this rare complication following TDA surgery.
Area of Science:
- Spine surgery
- Orthopedics
- Biomaterials
Background:
- Cervical total disc arthroplasty (TDA) is a motion-preserving alternative to anterior cervical discectomy and fusion.
- While effective, TDA is rarely associated with progressive osteolysis, a complication with poorly understood clinical impact.
Purpose of the Study:
- To report a case of progressive osteolysis after cervical TDA using the SpinalKinetics M6-C Artificial Cervical Disc.
- To discuss the clinical approach and management implications for this complication.
Main Methods:
- Case report detailing a patient who underwent cervical TDA with the M6-C disc.
- Review of the patient's clinical course, including symptom onset, diagnostic imaging (CT), and treatment progression.
Main Results:
- Progressive osteolysis was identified via CT imaging with a delayed onset of symptoms.
- The slow progression highlights the need for vigilant monitoring, as subtle early symptoms can lead to significant issues.
Conclusions:
- Progressive osteolysis is a potential complication of cervical TDA.
- Ongoing surveillance and surgeon awareness are vital for early identification and management to mitigate severe outcomes.
