Article Abstract
Background: The advanced stage of vertebral involvement in spinal tuberculosis (STB) can cause vertebral body collapse, which leads to kyphotic deformity and paraplegia in severe cases. Surgery is indicated in patients having disabling back pain, progressive neurological deficit, and instability in spine despite conservative management. The derangement of lumbar parameters, especially the loss of lumbar lordosis has been found to cause functional deterioration in patients. With the current evidences in place, this study was done to evaluate the correlation between the restoration of lumbar lordosis, pelvic parameters, and functional outcome when posterior only approach was used to manage the lumbar STB.
Methods: Active Tuberculosis of lumbar vertebra (L1-S1) confirmed by radiology (X-ray, MRI) and histopathological examination were included. All the cases scheduled for surgery underwent radiographs, CT scan, and MRI scans. Lumbar lordosis and other pelvic parameters were calculated on X-rays. VAS scores and ODI scores were documented during the follow-up to assess functional well-being.
Results: A total of 33 (22 M:11 F) patients were included in the study. The mean lumbar lordosis pre-operatively was -22.84 ± 11.19° which was corrected to -37.03 ± 9.02° (p < 0.05) post-operatively. The pelvic tilt pre-operatively was 25.33 ± 6.75° which was corrected to 19.63 ± 5.84° (p < 0.05) post-operatively. The mean ODI improved from 84.33 ± 11.84 to 26.93 ± 8.74 (p < 0.05) at the final follow-up. The mean VAS score pre-operatively was 8.06 ± 1.27 which improved to 2.45 ± 0.93 (p < 0.05) in the post-operative period.
Conclusion: The study found a strong negative correlation between ODI scores and lumbar lordosis and a strong positive correlation between pelvic tilt and ODI scores. But the correlation needs to be further studied and evaluated by a well-constructed study especially with a control group treated conservatively.

Comparison of oblique lumbar interbody fusion with pedicle screw fixation versus stress endplate augmentation and anterolateral screw fixation for degenerative lumbar spinal stenosis in osteoporotic patients.

Purpose: This study aims to assess the outcomes of combining oblique lumbar interbody fusion (OLIF) with anterolateral screw fixation (ASF) and stress endplate augmentation (SEA) in comparison to OLIF combined with pedicle screw fixation (PSF) for the treatment of degenerative lumbar spinal stenosis (DLSS) in patients with osteoporosis (OP).
Methods: We performed a retrospective analysis of patients diagnosed with DLSS who underwent OLIF in conjunction with either SEA and ASF (SEA-ASF group) or PSF (PSF group). Clinical outcomes, including the visual analog scale (VAS) scores for lumbar and leg pain, as well as the Oswestry Disability Index (ODI), were assessed at various postoperative intervals and compared to preoperative values.
Are the Clinical Outcomes of Lumbar Stenosis in Achondroplasia Associated With the Severity of Stenosis and Sagittal Balance?

Background: Lumbar spinal stenosis (LSS) is common in adults with achondroplasia and predisposes individuals to neurogenic claudication. It remains unverified whether the severity of stenosis in patients with achondroplasia is associated with clinical outcomes. Similarly, the role of sagittal balance parameters in clinical outcomes has not been determined.

Background: Single-position prone transpsoas lateral lumbar interbody fusion (PTP-LLIF) is an evolving minimally invasive surgery technique that merges the biomechanical and anatomical advantages of prone positioning with the LLIF approach. While PTP-LLIF enhances lumbar lordosis restoration and operative efficiency by eliminating patient repositioning, it presents unique ergonomic and visualization challenges for surgeons. This technical report describes a novel modification of the technique using the Teligen camera to improve intraoperative visualization and reduce surgeon fatigue.

Objective: The objective of this study was to introduce and evaluate foraminoplastic inferior pedicle subtraction osteotomy (FiPSO), a novel technique that involves downward resection of the pedicle and vertebral body, aimed at addressing rigid lower lumbar kyphosis.
Methods: The clinical records were reviewed of the patients who underwent corrective surgery from January 2012 through December 2021 for adult spinal deformity using a combination of procedures: pedicle subtraction osteotomy (PSO) at the lumbar level and spinopelvic fixation. Inclusion criteria included patients older than 40 years with sagittal imbalance symptoms and significant radiographic findings: sagittal vertical axis (SVA) > 50 mm, pelvic tilt (PT) > 25°, or pelvic incidence (PI) minus lumbar lordosis (LL) > 10°.
