Eligibility
Inclusion criteria
Inclusion criteria: 1. Undergoing single-level MIS-TLIF for degenerative lumbar conditions (e.g., spinal stenosis, low-grade spondylolisthesis) at SSHRI during the study period. 2. Availability of high-quality lumbar MRI scans both before and after surgery (axial T2 sequences at the fused level). 3.Minimum radiographic follow-up of 6 months.
Exclusion criteria
Exclusion criteria: 1. History of prior lumbar spine surgery at the index or adjacent levels. 2. Surgery for non-degenerative pathology (e.g., tumor, infection, trauma). 3. Multi-level fusion procedures (more than one operative level). 4. Incomplete clinical records or missing imaging data at required time points. 5. Contraindications to MRI (e.g., incompatible implants), resulting in no postoperative MRI.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The following outcome measures will be recorded from each patient s chart and imaging studies: Dural sac area (mm ): Measured on axial T2-weighted MRI at the level of surgery (and adjacent levels). Canal diameters (mm): Anteroposterior and transverse diameters of the spinal canal on axial MRI. Clinical scores: Pre- and postoperative pain (VAS) and disability (ODI) if documented. Complications: Any intraoperative or postoperative adverse events noted in records Timepoint: Postoperative follow-up imaging included routine standing radiographs at 3 and 12 months to assess alignment and fusion, and MRI as clinically indicated. The primary imaging endpoint for this study is the postoperative MRI, which is usually obtained at approximately 6 12 months after surgery to evaluate nerve decompression and canal status. | — |
