First 2 image r before operation and next 2 r after operation image
I can see all 4 X-ray images clearly. Let me provide a comparison analysis.

Here is a structured before/after comparison for patient MANI K, Male, 71 years (DOB: 21 Aug 1954):
Pre-operative X-rays - 9 Jul 2026 (Lumbo-Sacral Spine)
Image 1 - Flexion (FLEX) view, lateral:
- Significant loss of lumbar lordosis
- Marked disc space narrowing at the lower lumbar levels (L4-L5 and L5-S1)
- Degenerative changes with osteophyte formation
- Vertebral endplate irregularities
- No hardware present
- Possible spondylolisthesis (forward slipping) at the lower lumbar segments - the flexion view accentuates any instability
Image 2 - Extension (Ext) view, lateral:
- Lumbar lordosis partially preserved on extension
- Confirms degenerative disc disease at L4-L5 and L5-S1
- Disc space collapse visible at lower levels
- Facet joint arthropathy
- Dynamic instability suggested when comparing flex vs ext views - this is a key finding indicating segmental instability that likely prompted surgical intervention
Post-operative X-rays - 10 Jul 2026 (Lumbo-Sacral Spine)
Image 3 - Lateral (LAT) view:
- Posterior spinal instrumentation in situ - pedicle screws with connecting rods visible at L4-L5 and L5-S1 levels (2-level fixation)
- An interbody cage/spacer appears to be placed at L4-L5 and/or L5-S1 (consistent with PLIF or TLIF - Posterior/Transforaminal Lumbar Interbody Fusion)
- Disc height appears restored at the operated levels compared to pre-op
- Lordosis appears better maintained post-operatively
- Hardware alignment looks appropriate on lateral view
Image 4 - AP (Antero-Posterior) view:
- Bilateral pedicle screws clearly visible at 2 lumbar levels (L4 and L5, with possible S1 fixation)
- Connecting rods on both sides
- Interbody implant visible centrally
- Screws appear well-positioned bilaterally - symmetric placement
- No obvious hardware malposition or fracture seen
Summary
| Feature | Pre-op (9 Jul) | Post-op (10 Jul) |
|---|---|---|
| Hardware | None | Pedicle screws + rods + interbody cage |
| Disc height | Collapsed at L4-L5, L5-S1 | Restored |
| Lordosis | Reduced/flat | Improved |
| Stability | Dynamic instability on flex/ext | Fixed with instrumentation |
| Procedure | - | Lumbar fusion (PLIF/TLIF) L4-L5 ± L5-S1 |
Operation performed: Posterior lumbar instrumented fusion with interbody cage (PLIF or TLIF), likely at L4-L5 and L5-S1, done between 9 Jul and 10 Jul 2026. The immediate post-op films show well-positioned hardware with good restoration of disc space height and lumbar alignment.
Note: This is an image-based radiological observation only. Clinical correlation with operative notes and formal radiologist report is essential for medical decision-making.
