文摘

Acute fixed cervical kyphosis may be a rare presentation of conversion disorder, psychogenic dystonia, and potentially as a side effect from typical antipsychotic drugs. Haldol has been associated with acute dystonic reactions. In some cases, rigid deformities ensue. We are reporting a case of a fixed cervical kyphosis after the use of Haldol.PurposeTo present a case of a potential acute dystonic reaction temporally associated with Haldol ingestion leading to fixed cervical kyphosis.Study designThis is a case report.MethodsA patient diagnosed with bipolar disorder presented to the emergency room several times with severe neck pain and stiffness. The neck appeared fixed in flexion with extensive osteophyte formation over a 3-month period.ResultsThe patient's condition was resolved by a posterior-anterior-posterior surgical approach. It corrected the patient's cervical curvature from 88° to 5°.ConclusionsAcute dystonic reactions have the potential to apply enough pressure on bone to cause rapid osteophyte formation.
