Conversion XXXX after cervical spine arthroplasty: a case report and literature review.

We report a case of conversion @entity912 after cervical spine arthroplasty performed in a 45-year-old @entity1 to treat cervico- @entity11438 due to a left-sided C6-C7 disc herniation. Upon awakening from the anaesthesia, she had left @entity1158 sparing the face, with normal sensory function. Magnetic resonance imaging (MRI) of the brain ruled out a @entity64 . MRI of the spinal cord showed artefacts from the @entity1953 -chrome prosthesis that precluded confident elimination of mechanical @entity1745 . Surgery performed on the same day to substitute a cage for the prosthesis ruled out @entity1745 , while eliminating the source of MRI artefacts. Findings were normal from follow-up MRI scans 1 and 15days later, as well as from neurophysiological testing (electromyogram and motor evoked potentials). The deficit resolved fully within the next 4days. A psychological assessment revealed @entity147 related to an ongoing divorce. The most likely diagnosis was conversion @entity912 . Surgeons should be aware that @entity13299 might develop after a procedure on the spine, although the risk of litigation requires re-operation. Familiarity with specific MRI sequences that minimise artefacts can be valuable. A preoperative psychological assessment might improve the detection of @entity1 at high risk for @entity13299 .
