i just had catscan cuz of presisting back hip pain. I am 5 mounth post back surgey also 4.5 year post total hip replacement, I cannot step on hip without horrendios pain here is my cat scan sepy2015
Exam: CT of the lumbar spine without contrast
Comparison: MRI dated 9/6/2014
Additional clinical data: Post laminectomy syndrome.
Helically acquired imaging was obtained of the lumbar spine. Sagittal and coronal 2D reformations performed by technologist. Soft tissue and bone algorithm images reviewed
Status post revision of prior posterior lumbar fusion with interval removal of left pedicle screws at L5 and S1. Surgical changes status post posterior decompression and fusion at L3-L4. There is also evidence of posterior decompression at L4-L5 and L5-S1. Interbody grafts are present at L3-L4 and L5-S1. The L3-L4 interbody graft appears to be incorporated into the L4 superior endplate. The L5-S1 interbody graft appears to be incorporated in to both endplates. Bone graft material is identified posterolaterally, with apparent fusion at L3-S1. Status post left SI joint fusion with three screws transfixing this joint. Left SI joint is partially fused. Hardware appears intact. Ghost tracks within the sacrum from prior hardware. Metallic/graft material present within the left sacrum, without extension into the adjacent neuroforamen. Left hip arthroplasty incompletely characterized. Spinal cord stimulator enters the posterior epidural space at T10-T11, the superior tip of which is not visualized.
There is obliteration of the fat planes with inhomogeneous appearance between the paraspinous muscles, more so centrally, extending from L3-S1. This may represent fatty replacement, however a fluid collection cannot be excluded.
Bilateral SI joint arthrosis
1. Status post revision of prior posterior lumbar fusion as stated in the body of the report
2. Obliteration of the fat planes with inhomogeneous appearance between the paraspinous muscles, more so centrally, extending from L3-S1. This may represent fatty replacement, however a fluid collection cannot be excluded.
