Technological developments over the last two centuries have advanced t
he spinal surgeon's capability to service the needs of spinal cord inj
ured person. While the role that surgery can play in shortening hospit
alization for tetraplegics has yet to be proven, it does play a much n
eeded role in the correction of instability and prevention of deformit
y when the possibility of these conditions exist. Surgical interventio
n for purposes or neural decompression has yet to be proven as justifi
able in view of the risks involved. All surgical procedures must be un
dertaken only after due consideration of the patients' general medical
condition, including coexisting trauma, the potential for and actual
instability and deformity of the spine, and the neurological level and
degree of incompleteness of the patient. In general, the greater the
remaining neurological function, the more there is to gained by early
mobilization. Yet, in the face of progressive improvement in neurologi
cal function, caution is advised since there will be much to lose if a
nything goes wrong with the operation.
