Abstract
|
|
|
The conus medullaris syndrome, which means injury of the sacral cord(conus) and nerve roots within the spinal canal, is very rare. It is usually associated with injury or disease of thoracolumbar vertebrae(T12-L1) and results in areflexic
bladder,
bowel
and loss of sensory and motor function of lower extremities.
Between he two types of conus medullaris syndrome, isolated type(lesion of sacral cord alone) is more rare than the mixed type(lesions of both the cauda equina and conus medullaris). Clinical features of isolated conus medullaris syndrome are
loss
of
bladder, external anal sphincter and sexual function.
We experienced a cases of isolated conus medullaris syndrome associated with L4 bursting fracture, which showed neurologic deficits confined to areflexia of bladder and anal sphincter without any sensory and motor dysfunctions of lower
extremities.
The
patients was managed with posterior decompression and posterolateral fusion using C-D instrumentation and showed gradual recovery of the neurologic deficits.
