Abstract
A sacroiliac joint implant system includes a primary implant configured to be received in a sacroiliac joint of a patient and a secondary implant configured to couple with the primary implant. The primary implant includes a body extending from a proximal end to a distal end and a plurality of threads extending from the body. The secondary implant includes a first anchor configured to anchor within a sacrum of the patient and a second anchor configured to anchor within an ilium of the patient.
Claims19
A sacroiliac joint implant system, comprising:
- a primary implant configured to be received in a sacroiliac joint of a patient;
- and
- a secondary implant configured to couple with the primary implant, the secondary implant comprising:
- a first anchor configured to be driven within a sacrum of a patient, the first anchor comprising a distal end having an inwardly facing beveled edge, the inwardly facing beveled edge of the first anchor extending distally to an outer face of the first anchor to form a sharp distal tip;
- and
- a second anchor configured to be driven within an ilium of the patient, the second anchor comprising a distal end having an inwardly facing beveled edge, the inwardly facing beveled edge of the second anchor extending distally to an outer face of the second anchor to form a sharp distal tip;
- wherein the beveled edge of the first anchor and the beveled edge of the second anchor are shaped and positioned to cause compression between the sacrum and the ilium when the first anchor is driven into the sacrum and the second anchor is driven into the ilium, and
- wherein each of the first anchor and the second anchor comprises a curved wedge that curves radially around the primary implant when the secondary implant is coupled with the primary implant.
A sacroiliac joint implant system, comprising:
- a primary implant configured to be received in a sacroiliac joint of a patient;
- and
- a secondary implant configured to couple with the primary implant, the secondary implant comprising:
- a ring;
- a plurality of arms extending laterally from the ring;
- a first anchor extending from a first arm of the plurality of arms, wherein the first anchor is configured to be driven within a sacrum of a patient, the first anchor comprising a distal end having an inwardly facing beveled edge, the inwardly facing beveled edge of the first anchor extending distally to an outer face of the first anchor to form a sharp distal tip;
- and
- a second anchor extending from a second arm of the plurality of arms, wherein the second anchor is configured to be driven within an ilium of the patient, the second anchor comprising a distal end having an inwardly facing beveled edge, the inwardly facing beveled edge of the second anchor extending distally to an outer face of the second anchor to form a sharp distal tip;
- wherein the beveled edge of the first anchor and the beveled edge of the second anchor are shaped and positioned to cause compression between the sacrum and the ilium when the first anchor is driven into the sacrum and the second anchor is driven into the ilium,
- wherein the primary implant comprises a head and a shank extending distally from the head, wherein a proximal end of the head of the primary implant is configured to be positioned radially within the ring of the secondary implant.
