Failed SI Joint Fusion

Thank you so much for your reply. I have had a CT scan and it also said, “no evidence of bony fusion”. Do you perform SI fusion revisions?

The original technique was a iFuse Sibone implants. I have 3 implants on my left SI joint. The surgical technique was closed technique.

MRI results date 7/9/19:FINDINGS:Three internal fixation screws bridge the left SI joint. These do produce moderate metallic artifact. Portions of the SI joint which are visualized without artifact appear normal. No evidence of bony fusion. No abnormal signal present within the osseous elements. No edematous change or evidence of inflammation within the SI joints. Joint spaces within the hips appear relatively well maintained. No mass lesions or abnormal fluid collections. Soft tissue structures appear unremarkable. Uterus appears surgically absent.

CT results date 4/22/19:CONCLUSION:1. Three fusion devices bridges the left SI joint. No definite bony fusion. Findings similar to 11/23/2018.Dictated by: Charles Fowler M.D. on 4/22/2019 at 10:28

MRI results date 12/31/19:
FINDINGS:PARASPINAL AREA:New postsurgical hypointense metallic artifacts from hardware fixation device about the left sacroiliac joint. No marrow edema or fluid signal is seen about the SI joints or in the adjacent bone marrow. No definite fluid within the sacroiliac joint. Right SI joint is normal. No marrow edema to suggest a sacral insufficiency fracture or stress reaction. The metallic blooming artifacts abut the lateral margins of the left sacral neural foramina but the exiting nerve roots appear unremarkable. On the prior CT exam, the sacral neural foramina appear intact. Paraspinal soft tissues
unremarkable. No soft tissue fluid or edema. The gluteal muscles appear normal in size signal and bulk. No fluid collection or soft tissue edema.BONES:Bone marrow signal is maintained. Normal alignment of the lower thoracic and lumbar spine. Vertebral heights maintained. Intervertebral disc spaces are within normal range. Minimal degenerative endplate osteophytes throughout lumbar spine. No suspicious marrow signal abnormalities.CORD/CAUDA EQUINA: Normal caliber, contour, and signal intensity. Conus lies at the L1 level.
LUMBAR DISC LEVELS:L1-L2:No significant disc/facet abnormality, spinal stenosis, or foraminal stenosis.
L2-L3:Mild disc bulging. Normal facet joints. No canal or foramen stenosis.L3-L4:Unchanged minimal disc bulging. Small posterior annular disc tear without change. Mild facet hypertrophy. No canal or foramen stenosis.
L4-L5:Left laminectomy changes. Mild facet hypertrophy. Small left facet effusion. No significant change. No disc protrusion. There is unchanged mild left foraminal disc bulging. Mild left foramen stenosis without change. No nerve root compression seen. Normal right foramen.
L5-S1:Unchanged mild posterior disc bulging and small posterior annular disc tear. No new disc protrusion. No canal stenosis. Mild bilateral facet hypertrophy. No joint effusion. Normal bilateral lateral recesses. Both neural foramen are normal. The exiting L5 and S1 nerve roots appear intact.

CONCLUSION:1. Lumbar spine shows no significant change.2. Mild degenerative disc bulging with small posterior annular disc tears at L3-4 and L5-S1. Unchanged.3. No canal stenosis.4. Unchanged left foraminal disc bulging at L4-5 with mild left foramen narrowing. No nerve root compression or displacement seen5. New postop changes of left SI joint fusion. Sacral neural foramina appear patent.6. No abnormal fluid or marrow signal abnormality about the sacrum or sacroiliac joint.

Is there any possibility that you would be able to help? I have SI bone pain and some nerve pain that is in the low back, butt area, and down the leg.
