Case ReportsSynovial cysts and the lithotomy position causing cauda equina syndrome.
We describe a case of cauda equina syndrome caused by synovial cysts and the lithotomy position. A transurethral resection of the prostate was performed under spinal anesthesia in the lithotomy position. ⋯ We believe that positioning the patient in the lithotomy position narrowed the cross-sectional area of the spinal canal in a patient with a coexisting critically stenosed lumbar spinal canal. The resultant mechanical pressure caused an ischemic compression injury to the cauda equina.
