Selecting caudal fusion levels: 2 year functional and stiffness outcomes with matched pairs analysis in multilevel fusion to L5 versus S1
Controversy persists as to whether to end multilevel thoracolumbar fusions caudally at L5 or S1. Some argue that stop** at L5 may preserve greater function, but there are few data comparing functional limita...
