Study Design: Secondary analysis of prospective study.

Objective: To analyze the impact of prior total knee arthroplasty (TKA), total hip arthroplasty (THA), or both on the Oswestry Disability Index (ODI) two years after elective lumbar surgery.

Background: Degenerative conditions that cause pain and mobility loss significantly reduce quality of life.

Previous Hip or Knee Arthroplasty is Associated With Less Favorable Patient-reported Outcomes of Lumbar Surgery.

Study Design: Review of cohort studies.

Objective: To ascertain if previous hip (THA) or knee (TKA) arthroplasty was associated with patients' outcomes assessments of subsequent lumbar surgery, specifically overall satisfaction, less disability due to pain, and an affective appraisal reflecting emotional assessment of results.

Background: Hip, knee, and lumbar symptoms often co-exist and increasingly are managed with surgery.

Study Design: Retrospective review of cohort studies.

Objective: To analyze how different ODI subsections and their improvement affect patient satisfaction 2 years after elective lumbar surgery for degenerative lumbar spondylolisthesis (DLS).

The Impact of Paraspinal Muscle Degeneration on Oswestry Disability Index Subsections Two Years After Spinal Surgery for Degenerative Lumbar Spondylolisthesis.

Study Design: Secondary analysis of prospective study.

Objective: To investigate the impact of fatty infiltration (FI) in the paraspinal muscles (PM) on postoperative Oswestry Disability Index (ODI) subsection-scores in patients undergoing elective lumbar surgery for degenerative lumbar spondylolisthesis (DLS).

Background: DLS can increase FI in the PM like the multifidus (MF), erector spinae (ES), and psoas (PS), leading to greater spinal disability and higher ODI-scores.

The spinopelvic alignment in patients with prior knee or hip arthroplasty undergoing elective lumbar surgery.

Background Context: Concurrent degeneration of the lumbar spine, hip, and knee can cause significant disability and lower quality of life. Osteoarthritis in the lower extremities can lead to movement limitations, possibly requiring total knee arthroplasty (TKA) or total hip arthroplasty (THA). These procedures often impact spinal posture, causing alterations in spinopelvic alignment and lumbar spine degeneration.

The Association between prior arthroplasty and Paraspinal Muscle Degeneration in patients undergoing elective lumbar surgery.

Purpose: Spinal and lower extremity degeneration often causes pain and disability. Lower extremity osteoarthritis, eventually leading to total knee- (TKA) and -hip arthroplasty (THA), can alter posture through compensatory mechanisms, potentially causing spinal misalignment and paraspinal muscle (PM) atrophy. This study aims to evaluate the association between prior THA or TKA and PM-degeneration in patients undergoing elective lumbar surgery for degenerative conditions.

Background: Evaluating elective lumbar surgery care often involves patient-reported outcomes.

The relationship between paraspinal muscle atrophy and degenerative lumbar spondylolisthesis at the L4/5 level.

Background/context: Degenerative lumbar spondylolisthesis (DLS) is a prevalent spinal condition that can result in significant disability. DLS is thought to result from a combination of disc and facet joint degeneration, as well as various biological, biomechanical, and behavioral factors. One hypothesis is the progressive degeneration of segmental stabilizers, notably the paraspinal muscles, contributes to a vicious cycle of increasing slippage.

Predicting postoperative outcomes in lumbar spinal fusion: development of a machine learning model.

Background Context: Degenerative lumbar spondylolisthesis (DLS) is a prevalent spinal disorder, often requiring surgical intervention. Accurately predicting surgical outcomes is crucial to guide clinical decision-making, but this is challenging due to the multifactorial nature of postoperative results. Traditional risk assessment tools have limitations, and with the advent of machine learning, there is potential to enhance the precision and comprehensiveness of preoperative evaluations.

Association of abdominal aortic calcification and lower back pain in patients with degenerative spondylolisthesis.

Abdominal aortic calcification (AAC) is hypothesized to lead to ischemic pain of the lower back. This retrospective study aims to identify the relationship between AAC and lower back pain (LBP) in patients with degenerative lumbar spondylolisthesis. Lower back pain was assessed preoperatively and 2 years after surgery using the numeric analogue scale.

Association Between Osteoarthritis Burden and Intervertebral Disk Degeneration in Patients Undergoing Lumbar Spine Surgery for Degenerative Lumbar Spondylolisthesis.

Study Design: A retrospective analysis of prospectively collected data.

Objective: To assess the association between intervertebral disk degeneration and hip and knee osteoarthritis (OA) in patients with degenerative lumbar spondylolisthesis.

Background: The co-occurrence of hip OA and degenerative spinal pathologies was first described as the "hip-spine syndrome" and has also been observed in knee OA.

Examining the Role of Paraspinal Musculature in Postoperative Disability After Lumbar Fusion Surgery for Degenerative Spondylolisthesis.

Study Design: Retrospective analysis of prospectively enrolled patients.

Objective: To evaluate the relationship between paraspinal muscle (PM) atrophy and Oswestry Disability Index (ODI) improvement after spinal fusion surgery for degenerative lumbar spondylolisthesis.

Background: Atrophy of the PM is linked to multiple spinal conditions, sagittal malalignment, and increased postoperative complications.

Emerging Need for PROMs to Measure the Impact of Spine Disorders on Overall Health and Well-being: Measuring Expectations as an Example for Lumbar Degenerative Spondylolisthesis.

Assessing the impact of spine disorders such as lumbar degenerative spondylolisthesis (LDS) on overall health is a component of quality of care that may not be comprehensively captured by spine-specific and single-attribute patient-reported outcome measures (PROMs). : We sought to compare PROMs to the Lumbar Surgery Expectations Survey ("Expectations Survey"), which addresses multiple aspects of health and well-being, and to compare the relevance of surgeon-selected versus survey-selected Patient-Reported Outcomes Measurement Information System (PROMIS) items to LDS. : In a cross-sectional study, 379 patients with LDS preoperatively completed the Expectations Survey, Numerical Rating Pain Scales, Oswestry Disability Index (ODI), and PROMIS computer-adaptive physical function, pain, and mental health surveys.

Background Context: Fulfillment of expectations is a patient-centered outcome that has not been assessed based on fusion status for lumbar degenerative spondylolisthesis (LDS).

Purpose: To compare preoperatively cited expectations and 2-year postoperative fulfillment of expectations between patients undergoing decompression alone (no-fusion) vs. decompression plus fusion (fusion) for LDS.

Quantitative CT for Preoperative Assessment of Lumbar Degenerative Spondylolisthesis: The Unique Impact of L4 Bone Mineral Density on Single-Level Disease.

Quantitative computed tomography (qCT) efficiently measures 3-dimensional vertebral bone mineral density (BMD), but its utility in measuring BMD at various vertebral levels in patients with lumbar degenerative spondylolisthesis (LDS) is unclear. : We sought to determine whether qCT could differentiate BMD at different levels of LDS, particularly at L4-L5, the most common single level for LDS. In addition, we sought to describe patterns of BMD for single-level and multiple-level LDS.

Study Design: Cross-sectional preoperative and intraoperative imaging study of L4-L5 lumbar degenerative spondylolisthesis (LDS).

Objective: To determine if alternate imaging modalities would identify LDS instability that did not meet the criteria for instability based on comparison of flexion and extension radiographs.

Summary Of Background Data: Pain may limit full flexion and extension maneuvers and thereby lead to underreporting of true dynamic translation and angulation in LDS.

Psychological Stress Reported at the Start of the COVID-19 Pandemic and Subsequent Stress and Successful Coping in Patients With Rheumatic Diseases: A Longitudinal Analysis.
