[Treatment in spondylolisthesis with a dynamic percutaneous lumbar external fixator. A three year experience].
Degenerative spondylolisthesis is due to long time instability between segments, caused by ligament laxity. This originates subluxation, displacement and foramina stenosis with consequent root compression. It is frequent in L4-L5 in 50 year and older women. The objective of this work is to present a minimally invasive procedure for the treatment of spondylolisthesis, with a dynamic external fixator for percutaneous arthrodesis stabilization.
