Summary
Early dislocation of the Mobi-C cervical disc prosthesis occurred in a patient, necessitating revision surgery. This rare complication highlights the importance of surgeon awareness during cervical arthroplasty procedures.
Area of Science:
- Neurosurgery
- Orthopedic Surgery
- Spinal Surgery
Background:
- Cervical disc arthroplasty is a surgical procedure to replace damaged intervertebral discs.
- The Mobi-C prosthesis is an artificial disc used in cervical spine surgery.
- Complications, though rare, can occur following cervical disc replacement.
Observation:
- A 57-year-old male patient experienced early anterior dislocation of a Mobi-C prosthesis at C4-C5.
- The patient presented with recurrent cervicalgia and brachialgia, along with new-onset dysphagia.
- Radiographic assessment confirmed the prosthesis dislocation, occurring one month post-implantation.
Findings:
- The case details an unusual early complication of Mobi-C cervical disc prosthesis.
- Anterior dislocation of the C4-C5 Mobi-C prosthesis was identified.
- Revision surgery was required, involving prosthesis removal and cervical arthrodesis with iliac graft.
Implications:
- Surgeons performing cervical arthroplasty must be aware of potential early prosthesis dislocation.
- This complication, while rare, necessitates careful patient monitoring post-operatively.
- Understanding and anticipating such adverse events can improve patient outcomes in cervical spine surgery.
