Biomechanics of Transforaminal Endoscopic Approaches
Conclusion. The transforaminal endoscopic intracanal technique preserves the native ROM of lumbar vertebral segments and shows a trend toward relative biomechanical superiority over the inside-out technique and open decompression procedures. (Source: Spine)

Objective Evaluation of Neurogenic Intermittent Claudication for Patients With Lumbar Spinal Stenosis Based on Plantar Pressure Analysis
Study Design. A cross-sectional study. Objective. To quantify the severity of neurogenic intermittent claudication (NIC) for patients with lumbar spinal stenosis (LSS) based on the center of pressure trajectory. Summary of Background Data. NIC is one of the typical symptoms of LSS. So far, the severity level of NIC is mainly evaluated by the subjective description of patients, which might be biased by patients’ background differences and thus lead to an ineffective diagnosis or inappropriate treatment for LSS. Therefore, it remains necessary to develop a reliable clinical technique for quantitative eval...

Validation of Age-adjusted Ideal Sagittal Alignment in Terms of Proximal Junctional Failure and Clinical Outcomes in Adult Spinal Deformity
Conclusions. Overcorrection relative to age-adjusted sagittal alignment increases the risk of PJF development and is associated with poor clinical outcomes. Older patients and those with small PI are likely to be overcorrected in terms of the age-adjusted PI−LL target. Therefore, the age-adjusted alignment should be considered more strictly in these patients. (Source: Spine)

Multilevel Decompression Surgery for Degenerative Lumbar Spinal Canal Stenosis Is Similarly Effective With Single-level Decompression Surgery
Conclusions. Despite the longer surgical time and a larger volume of estimated blood loss, multilevel decompression surgery showed similar improvement to that of single-level surgery in terms of recovery of PROs and frequency of revision surgery. Multilevel decompression surgery provides good clinical outcomes with acceptable complication and revision rates when selecting appropriate patient and spinal levels. (Source: Spine)

Are Octogenarians at Higher Risk of Complications After Elective Lumbar Spinal Fusion Surgery? Analysis of a Cohort of 7880 Patients From the Kaiser Permanente Spine Registry
Conclusions. In a cohort of 7880 elective posterior instrumented lumbar fusion patients for degenerative disk disease or spondylolisthesis, we did not observe any significant risks of adverse events between patients aged 80 years and above and those aged 50 to 79 except for higher durotomies and 30-day pneumonia in the former. We believe octogenarians can safely undergo lumbar fusions, but proper preoperative screening is necessary to reduce the risks of 30-day pneumonia. (Source: Spine)

Lower Prevalence and Severity of Degenerative Changes in the Lumbar Spine in Elderly Hong Kong Chinese Compared With Age-Matched Italian Caucasian Women
Study Design. Cross-sectional observational study. Objective. The aim was to compare the prevalence and severity of radiographic lumbar spine degeneration between elderly Hong Kong Chinese and elderly Italian Caucasian women. Summary of Background Data. Rates of symptomatic low back pain and osteoporotic vertebral fracture have been shown to be lower in Asian and Chinese populations compared with Caucasians, but ethnic differences in spinal degeneration are less established. Methods. Lumbar spine lateral radiographs of 566 age-matched (mean: 73.6 yr; range: 65–87 yr) female subjects from two po...

Patients From Socioeconomically Distressed Communities Experience Similar Clinical Improvements Following Anterior Cervical Discectomy and Fusion
Study Design. Retrospective cohort. Objectives. The aim was to compare patient-reported outcome measures (PROMs) following anterior cervical discectomy and fusion (ACDF) when categorizing patients based on socioeconomic status. Secondarily, we sought to compare PROMs based on race. Summary of Background Data. Social determinants of health are believed to affect outcomes following spine surgery, but there is limited literature on how combined socioeconomic status metrics affect PROMs following ACDF. Materials and Methods. The authors identified patients who underwent primary elective one-level to fo...

Utility of Diffusion Basis Spectrum Imaging in Quantifying Baseline Disease Severity and Prognosis of Cervical Spondylotic Myelopathy
Conclusions. This findings demonstrate that DBSI measures may reflect baseline disease burden and long-term prognosis of CSM as compared with DTI. With further validation, DBSI may serve as a noninvasive biomarker following decompressive surgery. Level of Evidence. 3 (Source: Spine)

Preoperative Association Between Quantitative Lumbar Muscle Parameters and Spinal Sagittal Alignment in Lumbar Fusion Patients
Conclusion. Our findings indicate that psoas and lumbar spine extensor muscles interact differently on LL among men and women, creating a unique mechanical environment. Level of Evidence. Level 4. (Source: Spine)

Changes in the Utilization of Lumbosacral Epidural Injections Between 2010 and 2019
Study Design. A descriptive epidemiologic study. Objective. To analyze trends and patient characteristics for lumbosacral transforaminal and interlaminar/caudal epidural injection utilization over time. Background. Lumbosacral transforaminal and interlaminar/caudal epidural injections are considered for varying lumbar pathologies. Reported studies, physician practices, insurance authorization, and other factors may influence utilization patterns over time. Methods. Patients undergoing lumbosacral transforaminal and interlaminar/caudal epidural injections between 2010 and 2019 were identified in the...
