Abstract
Sacro-iliac joint stabilizing implants adapted for implanting across a SI joint from a dorsal approach. Methods of, and delivery tools adapted for implanting sacro-iliac joint stabilizing implants across a SI joint from a dorsal approach.
Claims13
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, the implant body including:
- a central joint portion 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 the 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
- 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 wherein with reference to a reference line that is orthogonal to the ilium lumen longitudinal axis, the ilium portion extends further distally than the sacrum portion and/or the sacrum portion extends further proximally than the ilium portion, wherein a sacrum lumen has a length that is greater than a length of the ilium lumen.
