Pereira EAC., Wilson-MacDonald J., Green AL., Aziz TZ., Cadoux-Hudson TAD.
We describe dropped head syndrome in a patient with Parkinson's disease receiving subthalamic nucleus deep brain stimulation (DBS). Posterior occipitocervical instrumented fusion after transarticular screw fixation of an odontoid fracture is shown and its rationale explained. Pedunculopontine nucleus DBS as treatment for fall-predominant Parkinson's disease, and globus pallidus interna DBS for dystonia-predominant Parkinson's disease, are discussed.
