Thirty patients underwent fixation of the thoracic and lumbar spine fr
om 1986 to 1990 using the Roy-Camille pedicular screw fixation system.
The spine was stabilized for a variety of pathologic entities includi
ng fracture, tumor, spondylolisthesis, postlaminectomy instability, an
d pseudarthrosis. All but one patient obtained solid fusion based on r
adiographic and clinical criteria with an average follow up of 19.5 mo
nths. All patients reported subjective improvement in preoperative pai
n levels. There were no neurologic complications associated with the s
urgical procedure. Roy-Camille plate fixation appears to offer a stabl
e surgical construct in the treatment of thoracic and lumbar spine ins
tability.
