Claims17
A sacroiliac (SI) joint stabilizing implant for implanting across a SI joint from a dorsal approach, comprising:
- an implant body having a wafer configuration with a width dimension greater than a height dimension, including,
- a central joint portion positioned for placement across the SI joint;
- an ilium portion on a first side of the central joint portion, the ilium portion sized and configured for implanting into an ilium when the implant is implanted across a SI joint from a dorsal approach,
- the ilium portion comprising an elongate ilium lumen extending from a distal opening to a proximal opening and having an ilium lumen longitudinal axis, the ilium lumen sized and configured to receive therein an ilium positioning guide, and;
- and
- a sacrum portion on a second side of the central joint portion, the sacrum portion sized and configured for implanting into a sacrum when the implant is implanted across the SI joint from the dorsal approach, and
- with reference to a reference line that is orthogonal to the ilium lumen axis, the ilium portion extends further distally than the sacrum portion and/or the sacrum portion extends further proximally than the ilium portion.
A sacroiliac (SI) joint stabilizing implant for implanting across a SI joint from a dorsal approach, comprising:
- an implant body having a wafer configuration with a width dimension greater than a height dimension, including,
- a central joint portion positioned for placement across the SI joint;
- an ilium portion on a first side of the central joint portion, the ilium portion sized and configured for implanting into an ilium when the implant is implanted across a SI joint from a dorsal approach;
- and
- a sacrum portion on a second side of the central joint portion, the sacrum portion sized and configured for implanting into a sacrum when the implant is implanted across the SI joint from the dorsal approach, and
- with reference to a reference line that is orthogonal to an implant body longitudinal axis, the ilium portion extends further distally than the sacrum portion and/or the sacrum portion extends further proximally than the ilium portion.
A method of positioning a sacroiliac (“SI”) joint stabilizing implant across an SI joint from a dorsal approach, comprising:
- advancing an implant body along a dorsal trajectory across the SI joint such that,
- a sacrum portion of the implant is positioned in a sacrum,
- an ilium portion of the implant is positioned in the ilium,
- a central portion of the implant body is positioned across the SI joint, and with reference to a reference line that is orthogonal to an implant body longitudinal axis, the ilium portion extends further distally than the sacrum portion and/or the sacrum portion extends further proximally than the ilium portion.
