The authors describe a technique for the relief of spinal cord compression associated with congenital kyphoscoliosis. A 13-year-old girl with congenital cervicothoracic kyphoscoliosis had undergone in situ fusion; spastic paraparesis and bladder disturbance developed postoperatively. Spinal cord detethering and posterolateral decompression temporarily arrested the neurological deterioration; however, the patient's condition then progressed to paraplegia with a partial sensory level at L-1. Imaging demonstrated persisting cord compression at the apex of the kyphotic curve. Transvertebral transposition of the spinal cord was performed using sagittal vertebrotomies, preserving the lateral aspects of the vertebral bodies, pedicles, and fusion mass. By 2 years postoperatively she had recovered normal sensation and good bladder function and was walking unaided. Transposition of the spinal cord may be used to relieve spinal cord compression associated with complex spinal deformities.
