Abstract:
1. A method of inserting a spinal implant into an intervertebral disc, the method comprising: defining a trajectory through a Kambin's triangle of the patient and towards a center of the intervertebral disc by extending an instrument through the Kambin's triangle, wherein extending the instrument through Kambin's triangle comprises: passing a first dilator tube along the trajectory through Kambin's triangle until the first dilator tube reaches the intervertebral disc to be treated; passing a second dilator tube over the first dilator tube until the distal end of the second dilator contacts the annulus; and passing an access cannula over the second dilator tube until the distal end of the access cannula contacts the annulus; enlarging the Kambin's triangle by moving cutting surfaces of the dilators against vertebrae about said trajectory; advancing the spinal implant through the access cannula along said trajectory utilizing the Kambin's triangle and into the intervertebral disc; and expanding a height of the spinal implant within the intervertebral disc.
