Cervical myelopathy presenting as a genu recurvatum gait disorder.

A 49-year-old man presenting with a genu recurvatum gait disorder was found to have a cervical myelopathy, probably on the basis of cervical spondylosis and a cervical disc herniation compromising a congenitally narrow cervical spinal canal. Satisfactory resolution of abnormal hyperextension of the knee was achieved through the use of an ankle-foot orthosis. A genu recurvatum gait disorder as the presenting sign of cervical myelopathy does not appear to have been reported previously.
