Brief Summary
For unilateral spinal block, spinal local anesthetics should take effect on the spinal nerves of one side. With full flexion of the spine, the cauda equina becomes tightened and hangs in the middle of the subarachnoid space. This study was performed to assess if flexion of the vertebral column facilitates unilateral spinal anesthesia.

Conditions
Outcome Measures
Primary Outcomes (1)
Time for the complete regression of pinprick spinal analgesia on the nondependent legs
Sensory and motor blockade were evaluated within 3 hour of intrathecal injection
Interventions
The patients maintained the lateral decubitus position with the hips and back fully flexed for 15 minutes.
the patients are allowed to straighten their flexed hips and back to obtain the normal lordotic curvature of spinal column
