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.
Claims17
A method for anterior lumbar interbody fusion comprising creating an insertion path from a first anterolateral region of a selected lumbar vertebra in a caudal direction across an intervertebral disc into an opposite anterolateral region of an adjacent lumbar vertebra, 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 laterally from the anterolateral region of the selected lumbar vertebra in a caudal direction across the intervertebral disc into an opposite anterolateral region of the adjacent lumbar vertebra.
A system comprising at least one 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 inserted through an insertion path laterally from an anterolateral region of the selected lumbar vertebra in a caudal direction across the intervertebral disc into an opposite anterolateral region of an adjacent lumbar vertebra to affect anterior lumbar interbody fusion.
A system comprising at least a first implant structure 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 enters on an anterolateral side of the selected lumbar vertebra, passes caudally through the intervertebral disc, and into an opposite anterolateral region of the adjacent lumbar vertebra, and at least a second implant structure comprising an elongated implant structure having a rectilinear cross section including an exterior surface region treated to provide bony in-growth or through-growth along the implant structure that enters through an opposite anterolateral side of the selected lumbar vertebra, passes caudally through the intervertebral disc and into the opposite anterolateral region of the adjacent lumbar vertebra, the first and second implant structures crossing each other in transit through the intervertebral disc, affecting anterior lumbar interbody fusion.
