Surgical treatment of lumbar vertebral collapse in a patient with Parkinson's disease: a case report.

Parkinson's disease (PD) frequently develops postural abnormalities including extreme neck flexion and trunk flexion. Patients with PD sometimes have osteopenia and vertebral deformity due to the destruction of fragile bone can be also associated with the spinal deformity. Surgical treatment for these patients is very difficult. We encountered a patient with PD presenting severe trunk sagittal and frontal deformity. The patient had cauda equina syndrome due to progressive vertebral collapse of the lumbar spine. We performed anterior reconstruction surgery at first in order to achieve improved lordotic alignment of the lumbar spine. Then, we performed 2 posterior surgeries, resulting in total long fusion from T4 to S1. The clinical findings of this patient were presented, and the treatment options were discussed.
