    Dr, an update, from my MRI with contrast findings. If you could please explain the following, I’d be very appreciative :

    T12/L1, L1/2, L2/3 and L3/4 disc spaces are preserved.
    L4/5: Status post left L4/5 laminectomy. There is mild symmetrical circumferential disc
    bulge with a small central disc protrusion indenting the anterior thecal sac as before. The
    degree of subarticular zone stenosis previously identified has improved. There is no spinal
    canal stenosis. The AP diameter of the CSF space is widely patent measuring 1.4 cm. In
    the left laminectomy bed, there is mild enhancement which demonstrate intermediate T2
    signal is suggestive of scarring and fibrosis. No discrete fluid collection. There is minimal
    mass effect of the dorsal left thecal sac but the spinal canal remains patent. No mass effect
    on the nerve roots. No significant abnormal epidural enhancement.
    L5/S1: There is metallic susceptibility artifact seen in the posterior aspect of the L5/S1 soft
    tissue. Note is made of L5/S1 laminectomy and discectomy. The previously seen left
    paracentral herniated disc and extrusion has completely resected. There is mild to
    moderate posterior disc height loss. There is persistent very mild central broad based disc
    protrusion indenting the anterior thecal sac but no spinal canal stenosis. The disc does not
    appear to be contacting the spinal canal. The subarticular zones are also patent. There is
    mild increased enhancement in the left epidural space in the surgical bed but there is no spinal canal stenosis. Mild enhancement of the left facet joint is also identified but no
    significant joint effusion. Minimal enhancement is seen in the posterior subcutaneous fat
    and posterior to the spinous processes at L5/S1 level.
    There is mild edema in the left paraspinal muscle in keeping with recent surgery. The rest
    of the paravertebral soft tissue is within normal limits.
    The conus medullaris terminates at L1 with normal signal intensity and morphology.
    IMPRESSION:
    1. The L5/S1 left paracentral disc protrusion and extruded disc has been resected. The
    L5/S1 disc height is decreased, with very mild central broad based disc protrusion without
    spinal canal stenosis or neural foraminal narrowing. There is mild enhancement in the left
    posterior epidural without compressing the nerve roots.
    2. L4/5 left laminectomy also identified. The previously seen mild to moderate lateral
    recess stenosis has improved. There is moderate enhancement in the left laminectomy bed
    suggestive of scarring. No large fluid collection identified. This does not impinge the nerve
    roots nor cause spinal canal stenosis .

    Hi @Thecarter

    I saw this post when searching on google.

    I am 4 weeks postop microdiscectomy/laminectomy and also have a positive SLR.

    It started 9 months ago with injury where main symptom was positive SLR but mainly in back. Then 5 months later I got really bad sciatica and got surgery after 4 additonal months.

    Almost all pain is gone except for positive SLR (mostly feel in back/hip)

    When did you achieve a negative SLR post surgery? What to expect? For me no improvement week on week

    Typically, the SLR (straight leg raise sign) calms down quickly but residual 10-20% of symptoms can take as long as 6 months to fade away.
