Abstract
Assemblies of one or more implant structures make possible the achievement of diverse interventions involving the fusion and/or stabilization of lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. The representative lumbar spine interventions, which can be performed on adults or children, include, but are not limited to, lumbar interbody fusion; translaminar lumbar fusion; lumbar facet fusion; trans-iliac lumbar fusion; and the stabilization of a spondylolisthesis.
Claims9
A method for stabilizing a spondylolisthesis at an articulation of a lumbar vertebra L5 and a sacral vertebra S1 comprising creating an insertion path that extends in a cranial direction from a posterolateral region of a sacral vertebra S1, through the adjoining intervertebral disc, and terminates in an opposite anterolateral region of the lumbar vertebra L5, providing a bone fixation implant comprises an elongated implant structure having a rectilinear cross section along at least a proximal portion of the implant structure and including an exterior surface region treated to provide bony in-growth or through-growth along the implant structure, and inserting the bone fixation implant through the insertion path from the posterolateral region of the sacral vertebra S1, through the adjoining intervertebral disc, and terminating in an opposite anterolateral region of the lumbar vertebra L5.
A system comprising at least one bone fixation implant comprising an elongated implant structure having a rectilinear cross section along at least a proximal portion of the implant structure and including an exterior surface region treated to provide bony in-growth or through-growth along the implant structure inserted through an insertion path that that extends in a cranial direction from a posterolateral region of a sacral vertebra S1, through the adjoining intervertebral disc, and terminates in an opposite anterolateral region of the lumbar vertebra L5.
