Retrospective comparative study.To compare the incidence of proximal junctional kyphosis (PJK) between transverse process hooks (TPHs) and pedicle screws (PSs) at upper instrumented vertebrae (UIV) following adult spinal deformity (ASD) surgery.The choice UIV implant type may be important for avoiding PJK; however, few clinical studies have evaluated PJK according to used in ASD surgery.We retrospectively reviewed 39 consecutive patients with (mean age, 67 years; mean follow-up period, 41...
Study design. Cross-sectional study. Objective. Validate the diagnostic accuracy of a deep-learning algorithm for cervical cord compression due to degenerative canal stenosis on radiography. Summary Background Data. The diagnosis myelopathy is often delayed, resulting in improper management. Screening tools suspected would help identify patients who require detailed physical evaluation. Materials and Methods. Data from 240 (120 with magnetic resonance imaging 120 age sex-matched controls)...
Study Design: Level 3 retrospective cohort case-control study.Purpose: This study aimed to investigate the risk factors for distal junctional kyphosis (DJK) caused by osteoporotic vertebral fractures following spinal reconstruction surgery, with a focus on sagittal stable vertebra.Overview of Literature: Despite rarity reports DJK in this setting, was reported reduce when lower instrumented vertebra (LIV) extended posterior corrective fixation Scheuermann’s disease.Methods: included 46...
A retrospective case control study.The purpose of this study was to compare the surgical outcomes multilevel lateral lumbar interbody fusion (LIF) and posterior (PLIF) in treatment adult spinal deformity (ASD) evaluate sagittal plane correction by combining LIF with posterior-column osteotomy (PCO).The between PLIF ASD patients remain unclear.We retrospectively reviewed 31 who underwent combined PCO (LIF group, n=14) or (PLIF n=17) a minimum 2-year follow-up. In comparison groups, their mean...
Abstract Compensatory mechanisms, such as a decrease in thoracic spine kyphosis and posterior tilting or rotation of the pelvis, aim to achieve optimal alignment spine. However, effect muscle strength on these compensatory mechanisms has not been elucidated. This study aimed investigate impact back lower extremity elderly people. Overall, 409 community-dwelling participants (164 men, 245 women) were included. Age, disc degeneration, 2 more vertebral fractures showed significant increase risk...
The cervical ossification of the posterior longitudinal ligament (cOPLL) is sometimes misdiagnosed or overlooked on radiography. Thus, this study aimed to validate diagnostic yield our deep learning algorithm which diagnose presence/absence cOPLL radiography and highlighted areas in positive cases compare its accuracy with that experienced spine physicians. Firstly, radiographic data 486 patients (243 243 age sex matched controls) who received a computer tomography were used create...
Trunk muscles play an important role in supporting the spinal column. A decline trunk muscle mass, as measured by bioelectrical impedance analysis (TMM–BIA), is associated with low back pain and poor quality of life. The purpose this study was to determine whether TMM–BIA correlates quantitative functional assessments traditionally used for muscles. We included 380 participants (aged ≥ 65 years; 152 males, 228 females) from Shiraniwa Elderly Cohort (Shiraniwa) study, whom following data were...
Abstract Ligamentum flavum (LF) hypertrophy is a major cause of lumbar spinal canal stenosis. Although mechanical stress thought to be factor involved in LF hypertrophy, the exact mechanism by which it causes has not yet been fully elucidated. Here, changes gene expression due long‐term were analyzed using RNA‐seq rabbit model. In combination with previously reported analysis results, periostin was identified as molecule whose fluctuates stress. The and function further investigated human...
Several studies have examined the relationship between sagittal spinopelvic alignment and clinical outcomes after spinal surgery. However, long-term reciprocal changes in patients with lumbar stenosis decompression surgery remain unclear. The aim of this study was to investigate radiographic at 2-year 5-year follow-ups minimally invasive
Hypertrophy of the ligamentum flavum (LF) is a major cause lumbar spinal stenosis (LSS), and pathology involves disruption elastic fibers, fibrosis with increased cellularity collagens, and/or calcification. Previous studies have implicated expression proteoglycan family in hypertrophied LF. Furthermore, gene profile rabbit experimental model LF hypertrophy revealed that biglycan (BGN) upregulated by mechanical stress. However, function BGN human has not been well elucidated. To investigate...
Study Design. Retrospective cohort study. Objective. To compare the clinical outcomes 5 years after minimally invasive posterior decompression for lumber spinal stenosis (LSS) between patients with and without degenerative spondylolisthesis (DS). Summary of Background Data. Indications surgical procedures LSS DS are still under investigation. Since surgery does not affect most anatomical structures, preoperative may negatively decompression. Methods. Overall, 198 who underwent...
