Systems, methods, and devices for lateral and posterior sacroiliac joint fusion

A method for sacroiliac (SI) joint fusion, comprising:

• providing instructions comprising:
• make a first incision on a patient to provide posterior access to the SI joint of the patient;
• insert, via a posterior approach, using a first insertion instrument, and through the first incision, a posterior SI implant into the SI joint such that the posterior SI implant engages with both a sacrum and an ilium of the patient,
• wherein the posterior SI implant comprises an externally threaded body and is cannulated along a longitudinal axis;
• make a second incision on the patient to provide lateral access to the SI joint;
• insert, via a lateral incision, using a second insertion instrument, and through the second incision, a lateral SI implant across the SI joint,
• wherein the lateral SI implant comprises:
• a main body;
• a pair of wings at a distal end of the main body, the pair of wings configured to be selectively positioned in an open configuration and a closed configuration;
• and
• an adjustable compressive body coupled to a proximal end of the main body and configured to adjust an amount of compression across the SI joint;
• and
• apply compression across the SI joint and to the posterior SI implant with the lateral SI implant.

• make a second incision on the patient to provide lateral access to the SI joint;
• insert, via a lateral approach and through the second incision, a lateral SI implant across the SI joint such that a distal end of the lateral SI implant is at least partially within the sacrum of the patient and a proximal end of the lateral SI implant at least partially protrudes from the ilium of the patient;
• and
• apply compression across the SI joint with the lateral SI implant.

A method for sacroiliac (SI) joint fusion, comprising:

• insert, through a first incision on a patient, a posterior SI implant into the SI joint such that the posterior SI implant engages with both a sacrum and an ilium of the patient,
• wherein the posterior SI implant comprises external threads along a length thereof to engage with the sacrum and the ilium;
• and
• insert, through a second incision on the patient, a lateral SI implant across the SI joint,
• wherein a distal end of the lateral SI implant is configured to engage with cortical bone of the sacrum, and
• wherein a proximal end of the lateral SI implant is configured to engage with the ilium.
