Definitions
- the present invention generally relates to an artificial sacroiliac joint prosthesis.
- the invention is directed to a sacroiliac joint prosthesis for movably connecting the sacrum to the ilium.
- the human hip girdle (see FIGS. 1 and 2 ) is made up of three large bones joined by two relatively immobile joints.
- One of the bones is called the sacrum and it lies at the bottom of the lumbar spine, where it connects with the L5 vertebra.
- the other two bones are commonly called “hip bones” and are technically referred to as the right ilium and the left ilium.
- the sacrum connects with both hip bones at the left and right sacroiliac joints (SI-Joint).
- the SI-Joint is a diarthrodial joint and operates to transfer large mechanical loads between the low back and the legs, while simultaneously allowing enough movement for the spine and extremities to function normally during daily activities.
- the sacral side of the SI-Joint contains hyaline cartilage that moves against fibrocartilage on the iliac side.
- the joint is generally L-shaped with ridges and depressions that interlock the sacrum and the ilium. This interlocking increases friction and minimizes motion allowing the joint to have a small amount of movement.
- SI-Joint When the joint has excessive motion, normal function of SI-Joint can be disrupted and the joint may become inflamed causing pain.
- the SI-Joint has been described as a pain generator for up to 22% of lower back pain.
- surgical treatment may be indicated.
- surgical treatment may be indicated for degenerative sacroiliitis, inflammatory sacroiliitis, iatrogenic instability of the sacroiliac joint, osteitis condensans ilii, or traumatic fracture dislocation of the pelvis.
- SI-Joint problems are typically treated non-surgically with medications, limiting activity, undergoing a therapy and exercise program, or radiofrequency ablation.
- surgery may be performed to fuse the Si-joint, eliminating motion between the sacrum and the ilium.

Description
- This patent application is a continuation of U.S. patent application Ser. No. 13/791,837, titled “ARTIFICIAL SI JOINT,” filed Mar. 8, 2013, now U.S. Pat. No. 8,778,026, which claims priority to U.S. Provisional Patent Application No. 61/609,195, titled “ARTIFICIAL SI JOINT,” and filed Mar. 9, 2012, each of which is herein incorporated by reference in its entirety.
- All publications and patent applications mentioned in this specification are herein incorporated by reference to the same extent as if each individual publication or patent application was specifically and individually indicated to be incorporated by reference.
- The present invention generally relates to an artificial sacroiliac joint prosthesis. In various respects, the invention is directed to a sacroiliac joint prosthesis for movably connecting the sacrum to the ilium.
- The human hip girdle (see
FIGS. 1 and 2 ) is made up of three large bones joined by two relatively immobile joints. One of the bones is called the sacrum and it lies at the bottom of the lumbar spine, where it connects with the L5 vertebra. The other two bones are commonly called “hip bones” and are technically referred to as the right ilium and the left ilium. The sacrum connects with both hip bones at the left and right sacroiliac joints (SI-Joint). - The SI-Joint is a diarthrodial joint and operates to transfer large mechanical loads between the low back and the legs, while simultaneously allowing enough movement for the spine and extremities to function normally during daily activities. The sacral side of the SI-Joint contains hyaline cartilage that moves against fibrocartilage on the iliac side. The joint is generally L-shaped with ridges and depressions that interlock the sacrum and the ilium. This interlocking increases friction and minimizes motion allowing the joint to have a small amount of movement.
- When the joint has excessive motion, normal function of SI-Joint can be disrupted and the joint may become inflamed causing pain. The SI-Joint has been described as a pain generator for up to 22% of lower back pain. To relieve pain generated from the SI-Joint and restore normal function of the SI-Joint, surgical treatment may be indicated. For example, surgical treatment may be indicated for degenerative sacroiliitis, inflammatory sacroiliitis, iatrogenic instability of the sacroiliac joint, osteitis condensans ilii, or traumatic fracture dislocation of the pelvis. Currently, problems associated with the SI-Joint are typically treated non-surgically with medications, limiting activity, undergoing a therapy and exercise program, or radiofrequency ablation. For more serious SI-Joint problems, surgery may be performed to fuse the Si-joint, eliminating motion between the sacrum and the ilium.
- There is a need for improved treatments for addressing chronic hip, joint or back pain caused by the SI-Joint.
- The present invention generally relates to an artificial sacroiliac joint prosthesis. In various respects, the invention is directed to a sacroiliac joint prosthesis for connecting the sacrum to the ilium and preserving motion therebetween.

-
FIGS. 1-2 are, respectively, anterior and posterior views of the human hip girdle. -
FIG. 3 is an enlarged lateral view of the sacrum. -
FIG. 4 is an enlarged lateral view of the sacral and lower lumbar region. -
FIG. 5 is a perspective view of the sacrum component of an exemplary artificial SI-Joint. -
FIG. 6 is a perspective view of the ilium component of an exemplary artificial SI-Joint. -
FIG. 7 is a cross-sectional view of an exemplary artificial SI-Joint. -
FIG. 8 is a cranio-caudal section view of an implanted exemplary artificial SI-Joint. - Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. While the invention will be described in conjunction with the exemplary embodiments, it will be understood that they are not intended to limit the invention to those embodiments. On the contrary, the invention is intended to cover alternatives, modifications and equivalents, which may be included within the spirit and scope of the invention as described herein.
- Various aspects of the present invention relate to an artificial sacroiliac joint prosthesis. In various embodiments, the artificial joint is implanted into the sacroiliac joint (SI-Joint).
-
FIGS. 1-2 are, respectively, anterior and posterior views of the human hip girdle including the sacrum and the hip bones (the right ilium and the left ilium), the sacrum being connected with both hip bones at the SI-Joints. - Each joint is encased and strengthened by two main ligaments, the interosseous (not shown) and the posterior sacroiliac ligaments (not shown). The ligaments allow slight movement during non-weight bearing and less movement during weight bearing movements. The slight movement of the SI-Joint allows the joint to have enough play to provide spinal shock absorption, enhance lower extremity torque conversions and transverse rotations.
- The spine and the lower extremities are connected by the pelvis. The spine movements occur in the sagittal plane and include flexion and extension. Hip movements may occur in all three planes, including a rotational motion which the lumbar spine does not perform well. As a result, the pelvic area should absorb the majority of lower extremity rotation, for example during bipedal gate.
-
FIG. 3 is an enlarged lateral view of the sacrum.FIG. 4 is an enlarged lateral view of the sacral and lower lumbar region. Thesacrum 2 includes anarticular surface 4 that unites with the articular surface of the ilium (not shown). The sacroiliac articulations form the SI-Joint that is a strong synovial joint between the sacrum and the ilium. The SI-Joint contains numerous ridges and complimentary depressions that provide friction and help interlock the two bones. Additionally, the sacrum is wedged anteroposteriorly allowing it to provide resistance to vertical and horizontal translation as illustrated inFIGS. 1 and 2 . Normal motion of the SI-Joint may include a combination of sliding, tilting and rotation. The SI-Joint may slide approximately 2 mm and may tilt or rotate approximately 2 to 4 degrees. The SI-Joint moves mostly along the sagittal plane about a point ofrotation 6 and should not move in the transverse plane. - The artificial joint may be designed to replace the SI-Joint mimicking its shape and movement. The artificial joint may include a
sacrum component 11 and anilium component 21.FIG. 5 is a perspective view of the sacrum component of an exemplary artificial SI-Joint. Thesacrum component 11 may include aridge 12, afoundation 14, aperimeter surface 16, and afitting member 18. Theridge 12 may be coupled to and extend away from thefoundation 14. In some embodiments, theridge 12 has a generally uniform and curved cross section in the longitudinal direction. In various embodiments,ridge 12 has a bell shape cross section.Ridge 12 may include aproximal end 15 and adistal end 17. Theproximal end 15 and thedistal end 17 of theridge 12 may be flat and not extend to the outer edge offoundation 14.Foundation 14 may include a generally flat surface that surroundsridge 12.

Ridge 12 andfoundation 14 may have acoating 20 that is conducive to bony in-growth, on-growth and/or through-growth.Coating 20 may be formed from titanium or titanium alloys. In some embodiments, thecoating 20 is a porous plasma spray coating. Thecoating 20 may create a biomechanically rigorous artificial joint prosthesis, designed to support acute weight bearing capacity. In various embodiments, theridge 12 andfoundation 14 may be formed from a material that itself inherently possesses a structure conducive to bony in-growth, on-growth and/or through-growth, such as a porous mesh, hydroxyapatite, or other porous surface. - The
coating 20 may include a material such as a biologic aid that may promote and/or enhance bony in-growth, bony on-growth, bony through-growth, tissue repair, and/or reduce inflammation, infection and pain. The biologic aid may include growth factors, such as bone morphogenetic proteins (BMPs), hydroxyapatite in a liquid or slurry carrier, demineralized bone, morselized autograft or allograft bone, medications to reduce inflammation, infection and pain such as analgesics, antibiotics and steroids. In various embodiments, the growth factors may be human recombinant growth factors, such as rh-BMP-2 and/or rh-BMP-7, or any other human recombinant form of BMP. The carrier for the biologic aid may be a liquid or gel such as saline or a collagen gel. - The biologic aid may also be encapsulated or incorporated in a controlled released formulation so that the biologic aid is released to the patient at the implant site over a longer duration. For example, the controlled release formulation may be configured to release the biologic aid over the course of days, weeks or months, and can be configured to release the biologic aid over an estimated time it would take for the implant site to heal. The amount of biologic aid delivered to the artificial SI-Joint may be controlled using a variety of techniques, such as controlling or varying the amount of coating material applied to the artificial SI-Joint and/or controlling or varying the amount of biologic aid incorporated into the coating material. Controlling the amount of biologic aid delivered may be important because excessive use of certain biologic aids may result in negative effects such as localized inflammation, local pain or radicular pain.
- The
coating 20 may further be covered with various other coatings such as antimicrobial, antithrombotic, and osteoinductive agents, or a combination thereof. In various embodiments, the entire artificial SI-Joint may be impregnated with such agents. -

Before insertion, the physician may identify where to place the pilot insertion path or bore through each of the sacrum bone segment and ilium bone segment. A single drill bit, multiple drill bits, reamer or other device may be employed to bore into the bone surfaces to create a pilot bore of the desired size and configuration. The physician may then insert the artificial SI-Joint into the bored portion of the
sacrum 2 andilium 3. In some embodiments, a curved insertion path or bore is formed in one or both of the sacrum and ilium, matching the radius of curvature of curved ridge(s) of the sacrum component and/or the ilium component. The radius of curvature of the ridges may be selected to match a radius of curvature of the bearing surfaces of the sacrum component and ilium component. This will allow the artificial joint to rotate about a point ofrotation 6, as shown inFIG. 3 . In some embodiments, the point ofrotation 6 is located outside and posterior of the body (not shown.) In some embodiments, the radius of the insertion path, ridges and bearing surfaces is within the range of about 10 mm and about 70 mm. In some embodiments, it may be 100 mm. In other embodiments, the insertion path and ridges may be straight. - In some embodiments, the artificial SI-Joint may be inserted as a single unit into the SI-Joint with a locking pin. The locking pin may be removed from the artificial SI-Joint after the joint is in position. In some embodiments, the artificial SI-Joint may be inserted in pieces into the bore portions of the
sacrum 2 and theilium 3. For example,ridge 12 may first be inserted into thesacrum 2 as a first piece andfoundation 14,perimeter surface 16, and fittingmember 18 may then be inserted into thesacrum 2 as a second piece coupled to the first piece.Foundation 28 andsockets 52 may be inserted into the ilium as a third piece andpolybearing 22 may be inserted into the ilium as a fourth piece coupled to the third piece. - Whether inserted as a single piece or multiple pieces, the artificial SI-Joint is inserted in such a manner as to avoid excessive damage to surrounding ligaments and other tissue to maximize the effectiveness of the artificial SI-Joint. When the insertion paths are curved as previously described, the artificial joint may be rotated into place as it is inserted along the path.
- In an embodiment that utilizes
screws 54 andsockets 52, an insertion path or bore may be formed from a lateral approach through the ilium to thesockets 52 of the artificial SI-Joint ilium component. The screws may be inserted through the ilium and received by thesockets 52 to secure the ilum component to the ilum. - The artificial SI-Joint makes possible a replacement prosthetic SI-Joint. The design and configuration of the artificial SI-Joint mimic the normal function of an SI-Joint allowing slight movement of approximately 2 to 4 degrees. A surface coating, for example a porous plasma spray coating with irregular surface, promotes bony in-growth, on-growth and/or through growth to provide a biomechanically rigorous prosthetic joint designed specifically to replace a dysfunctional SI-Joint and stabilize the heavily loaded lumbar spine. To minimize trauma to the ligaments and tissue, the artificial SI-Joint may be implanted as a single unit or as separate pieces that are coupled together.
