Fig. 3. Case of cervical myelopathy after cervical arthroplasty. (A) A 50-year-old female underwent cervical arthroplasty with Baguera-C. She experienced both forearm numbness and gait disturbance with cervical compressive myelopathy 4 years after CDA. She had an initial Japanese Orthopaedic Association score of 14. A cervical T2WI showed intramedullary high signal changes at the region of the compressed cord. (B) Cord compression and intramedullary signal changes on T2WI increased severely in the neck extension position. (C) The patient underwent cervical laminectomy with fusion at C5–6. The patient had a recovery ratio of 100%. CDA, cervical disc arthroplasty; T2WI, T2-weighted image.
